level of 0.15 percent, the chance is 25 times greater! The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I will be careful” is not the right answer. What if there is an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.


4-5


It is the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight will when each has the same number of drinks.


There is something else about drinking and driving that many people do not know. Medical research shows that alcohol in a person’s system can make crash injuries worse, especially injuries to the brain, spinal cord, or heart. This means that when anyone who has been drinking — driver or passenger — is in a crash, that person’s chance of being killed or permanently disabled is higher than if the person had not been drinking.


{CAUTION:


Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink.


Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering, and the accelerator.


All three systems have to do their work at the places where the tires meet the road.


Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Also see Traction Control System (TCS) on page 4-10.


4-6


Braking Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That is perception time. Then you have to bring up your foot and do it. That is reaction time. Average reaction time is about 3/4 of a second. But that is only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface of the road (whether it is pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied.


Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life. If your engine ever stops while you are driving, brake normally but do not pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push.


4-7


Anti-Lock Brake System (ABS) Your vehicle may have anti-lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid.


If your vehicle has anti-lock brakes, this warning light on the instrument panel will come on briefly when you start your vehicle.


When you start your engine, or when you begin to drive away, your anti-lock brake system will check itself. You may hear a momentary motor or clicking noise while this test is going on, and you may even notice that your brake pedal moves or pulses a little. This is normal.


4-8


Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel.


The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard.


As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.


Remember: Anti-lock does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel a slight brake pedal pulsation or notice some noise, but this is normal.


Braking in Emergencies At some time, nearly every driver gets into a situation that requires hard braking. If you have anti-lock, you can steer and brake at the same time. However, if you do not have anti-lock, your first reaction — to hit the brake pedal hard and hold it down — may be the wrong thing to do. Your wheels can stop rolling. Once they do, the vehicle can not respond to your steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling. That could be off the road, into the very thing you were trying to avoid, or into traffic.


4-9


If you do not have anti-lock, use a “squeeze” braking technique. This will give you maximum braking while maintaining steering control. You can do this by pushing on the brake pedal with steadily increasing pressure. In an emergency, you will probably want to squeeze the brakes hard without locking the wheels. If you hear or feel the wheels sliding, ease off the brake pedal. This will help you retain steering control. If you do have anti-lock, it is different. See Anti-Lock Brake System (ABS) on page 4-8
In many emergencies, steering can help you more than even the very best braking.


Traction Control System (TCS) Your vehicle may have a traction control system that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power to limit wheel spin.


This light will come on when your traction control system is limiting wheel spin. You may feel or hear the system working, but this is normal.


The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud, ice or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 4-32.


4-10


The traction control system can be turned off by pressing the traction control button, located on the instrument panel above the audio system. The traction control system can be activated again by pressing the traction control button.


If the system is limiting wheel spin when you press the button, the traction control off light will appear on the instrument panel cluster. The system will not turn off until there is no longer a current need to limit wheel spin. You can turn the system back on at any time by pressing the button again. If the light does not come on, you may not have traction control and your vehicle should be serviced by a dealer.


All-Wheel Drive (AWD) System If your vehicle has all-wheel drive (AWD), the AWD system operates automatically without any action required by the driver. If the front drive wheels begin to slip, the rear wheels will automatically begin to drive the vehicle as required. There may be a slight engagement noise during hard use but this is normal.


This light will come on when engine torque is reduced to protect the AWD system from overheating. You may feel or hear a change in engine output, but this is normal.


During heavy AWD applications, the engine torque may be reduced to protect AWD system components. If the vehicle is exposed to extended heavy AWD usage, the AWD system will shut itself off to protect the system from overheating. When the system cools down, the AWD system will activate itself again automatically; this cool-down can take up to 20 minutes depending on outside temperature and vehicle use. If the AWD system is unable to protect the system from overheating, the traction off light will come on to indicate no protection capability. If this light comes on, take your vehicle in for service.


4-11


Steering Electric Power Steering If the engine stalls while you are driving, the power steering assist system will continue to operate until you are able to stop your vehicle. If you lose power steering assist because the electric power steering system is not functioning, you can steer, but it will take more effort. If you turn the steering wheel in either direction several times until it stops, or hold the steering wheel in the stopped position for an extended amount of time, you may notice a reduced amount of power steering assist. The normal amount of power steering assist should return shortly after a few normal steering movements. The electric power steering system does not require regular maintenance. If you suspect steering system problems and/or the SERVICE light comes on, contact your dealer for service repairs.


Steering Tips Driving on Curves It is important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there is no traction, inertia will keep the vehicle going in the same direction. If you have ever tried to steer a vehicle on wet ice, you will understand this. The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at which the curve is banked, and your speed. While you are in a curve, speed is the one factor you can control. Suppose you are steering through a sharp curve. Then you suddenly apply the brakes. Both control systems — steering and braking — have to do their work where the tires meet the road. Unless you have four-wheel anti-lock brakes, adding the hard braking can demand too much of those places. You can lose control.


4-12


The same thing can happen if you are steering through a sharp curve and you suddenly accelerate. Those two control systems — steering and acceleration — can overwhelm those places where the tires meet the road and make you lose control. See Traction Control System (TCS) on page 4-10. What should you do if this ever happens? Ease up on the brake or accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you will want to go slower. If you need to reduce your speed as you approach a curve, do it before you enter the curve, while your front wheels are straight ahead. Try to adjust your speed so you can “drive” through the curve. Maintain a reasonable, steady speed. Wait to accelerate until you are out of the curve, and then accelerate gently into the straightaway.


Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking — if you can stop in time. But sometimes you can not; there is not room. That is the time for evasive action — steering around the problem. Your vehicle can perform very well in emergencies like these. First apply your brakes — but, unless you have anti-lock, not enough to lock your wheels. See Braking on page 4-7. It is better to remove as much speed as you can from a possible collision. Then steer around the problem, to the left or right depending on the space available.


4-13


Off-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving.


An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object. The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly.


4-14


If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement. You can turn the steering wheel up to one-quarter turn until the right front tire contacts the pavement edge. Then turn your steering wheel to go straight down the roadway.


Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds. A miscalculation, an error in judgment, or a brief surrender to frustration or anger can suddenly put the passing driver face to face with the worst of all traffic accidents — the head-on collision. So here are some tips for passing: (cid:127) Drive ahead. Look down the road, to the sides and to crossroads for situations that might affect your passing patterns. If you have any doubt whatsoever about making a successful pass, wait for a better time.


(cid:127) Watch for traffic signs, pavement markings and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it is all right to pass, providing the road ahead is clear. Never cross a solid line on your side of the lane or a double solid line, even if the road seems empty of approaching traffic.


(cid:127) Do not get too close to the vehicle you want to


pass while you are awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you are following a larger vehicle. Also, you will not have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance.


(cid:127) When it looks like a chance to pass is coming up,


start to accelerate but stay in the right lane and do not get too close. Time your move so you will be increasing speed as the time comes to move into the other lane. If the way is clear to pass, you will have a running start that more than makes up for the distance you would lose by dropping back. And if something happens to cause you to cancel your pass, you need only slow down and drop back again and wait for another opportunity. If other vehicles are lined up to pass a slow vehicle, wait your turn. But take care that someone is not trying to pass you as you pull out to pass the slow vehicle. Remember to glance over your shoulder and check the blind spot.


4-15


(cid:127) (cid:127) Check your mirrors, glance over your shoulder, and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. Remember that your right outside mirror is convex. The vehicle you just passed may seem to be farther away from you than it really is. Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle.


(cid:127) Do not overtake a slowly moving vehicle too rapidly.


Even though the brake lamps are not flashing, it may be slowing down or starting to turn. If you are being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right.


Loss of Control Let us review what driving experts say about what happens when the three control systems — brakes, steering, and acceleration — do not have enough friction where the tires meet the road to do what the driver has asked. In any emergency, do not give up. Keep trying to steer and constantly seek an escape route or area of less danger. Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to your vehicle’s three control systems. In the braking skid, your wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force. And in the acceleration skid, too much throttle causes the driving wheels to spin.


4-16


(cid:127) (cid:127) A cornering skid is best handled by easing your foot off the accelerator pedal. If you have the Traction Control System, remember: It helps avoid only the acceleration skid. If you do not have this system, or if the system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited.


While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration, or braking, including engine braking by shifting to a lower gear. Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. If you have the anti-lock braking system, remember: It helps avoid only the braking skid. If you do not have anti-lock, then in a braking skid, where the wheels are no longer rolling, release enough pressure on the brakes to get the wheels rolling again. This restores steering control. Push the brake pedal down steadily when you have to stop suddenly. As long as the wheels are rolling, you will have steering control.

Driving at Night


Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue.


4-18


Here are some tips on night driving. (cid:127) Drive defensively. (cid:127) Do not drink and drive. (cid:127) Adjust your inside rearview mirror to reduce the


glare from headlamps behind you.


(cid:127) Since you can not see as well, you may need to


slow down and keep more space between you and other vehicles.


(cid:127) Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead. In remote areas, watch for animals. If you are tired, pull off the road in a safe place and rest.


No one can see as well at night as in the daytime. But as we get older these differences increase. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. But if you are driving, do not wear sunglasses at night. They may cut down on glare from headlamps, but they also make a lot of things invisible.


(cid:127) (cid:127) You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare, as from a driver who does not lower the high beams, or a vehicle with misaimed headlamps, slow down a little. Avoid staring directly into the approaching headlamps. Keep your windshield and all the glass on your vehicle clean — inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a film caused by dust. Dirty glass makes lights dazzle and flash more than clean glass would, making the pupils of your eyes contract repeatedly. Remember that your headlamps light up far less of a roadway when you are in a turn or curve. Keep your eyes moving; that way, it is easier to pick out dimly lighted objects. Just as your headlamps should be checked regularly for proper aim, so should your eyes be examined regularly. Some drivers suffer from night blindness — the inability to see in dim light — and are not even aware of it.


Driving in Rain and on Wet Roads


Rain and wet roads can mean driving trouble. On a wet road, you can not stop, accelerate, or turn as well because your tire-to-road traction is not as good as on dry roads. And, if your tires do not have much tread left, you will get even less traction. It is always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement.


4-19


The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road, and even people walking. It is wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts.


Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you cannot, try to slow down before you hit them.


{CAUTION:


Wet brakes can cause accidents. They will not work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally.


4-20


Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road. Hydroplaning does not happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles, or other vehicles, and raindrops dimple the water’s surface, there could be hydroplaning. Hydroplaning usually happens at higher speeds. There just is not a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining. Driving Through Deep Standing Water Notice: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you can not avoid deep puddles or standing water, drive through them very slowly.


Driving Through Flowing Water


{CAUTION:


Flowing or rushing water creates strong forces. If you try to drive through flowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of flowing water can carry away a smaller vehicle. If this happens, you and other vehicle occupants could drown. Do not ignore police warning signs, and otherwise be very cautious about trying to drive through flowing water.


Some Other Rainy Weather Tips


Turn on your low-beam headlamps — not just your parking lamps — to help make you more visible to others.


(cid:127) Besides slowing down, allow some extra following


distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted by road spray.


(cid:127) Have good tires with proper tread depth. See Tires


on page 5-47.

(cid:127) City Driving


Here are ways to increase your safety in city driving: (cid:127) Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. Try to use the freeways that rim and crisscross most large cities. You will save time and energy. See Freeway Driving on page 4-23. Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it. When a light turns green, and just before you start to move, check both ways for vehicles that have not cleared the intersection or may be running the red light.


One of the biggest problems with city streets is the amount of traffic on them. You will want to watch out for what the other drivers are doing and pay attention to traffic signals.


4-22


(cid:127) (cid:127) Freeway Driving


Mile for mile, freeways — also called thruways, parkways, expressways, turnpikes, or superhighways — are the safest of all roads. But they have their own special rules.


The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the flow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors, and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic flow. Once you are on the freeway, adjust your speed to the posted limit or to the prevailing rate if it is slower. Stay in the right lane unless you want to pass. Before changing lanes, check your mirrors. Then use your turn signal. Just before you leave the lane, glance quickly over your shoulder to make sure there is not another vehicle in your blind spot. Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night.


4-23


Here are some things you can check before a trip: (cid:127) Windshield Washer Fluid: Is the reservoir full? Are


all windows clean inside and outside?


(cid:127) Wiper Blades: Are they in good shape?


Fuel, Engine Oil, Other Fluids: Have you checked all levels? Lamps: Are they all working? Are the lenses clean? Tires: They are vitally important to a safe, trouble-free trip. Is the tread good enough for long-distance driving? Are the tires all inflated to the recommended pressure?


(cid:127) Weather Forecasts: What is the weather outlook


along your route? Should you delay your trip a short time to avoid a major storm system?


(cid:127) Maps: Do you have up-to-date maps?


When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit. The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are.


Before Leaving on a Long Trip Make sure you are ready. Try to be well rested. If you must start when you are not fresh — such as after a day’s work — do not plan to make too many miles that first part of the journey. Wear comfortable clothing and shoes you can easily drive in. Is your vehicle ready for a long trip? If you keep it serviced and maintained, it is ready to go. If it needs service, have it done before starting out. Of course, you will find experienced and able service experts in GM dealerships all across North America. They will be ready and willing to help if you need it.

(cid:127) (cid:127) (cid:127) Highway Hypnosis Is there actually such a condition as highway hypnosis? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy. Do not let it happen to you! If it does, your vehicle can leave the road in less than a second, and you could crash and be injured. What can you do about highway hypnosis? First, be aware that it can happen. Then here are some tips: (cid:127) Make sure your vehicle is well ventilated, with a


comfortably cool interior.


(cid:127) Keep your eyes moving. Scan the road ahead and


to the sides. Check your mirrors and your instruments frequently. If you get sleepy, pull off the road into a rest, service, or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency.


Hill and Mountain Roads


Driving on steep hills or mountains is different from driving in flat or rolling terrain.


4-25


(cid:127) If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable. (cid:127) Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system, and transaxle. These parts can work hard on mountain roads.


(cid:127) Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill.


{CAUTION:


If you do not shift down, your brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let your engine assist your brakes on a steep downhill slope.


{CAUTION:


Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have your engine running and your vehicle in gear when you go downhill.


(cid:127) Know how to go uphill. You may want to shift down


to a lower gear. The lower gears help cool your engine and transaxle, and you can climb the hill better.


4-26


Winter Driving


(cid:127) Stay in your own lane when driving on two-lane roads in hills or mountains. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.


(cid:127) As you go over the top of a hill, be alert. There


could be something in your lane, like a stalled car or an accident.


(cid:127) You may see highway signs on mountains that


warn of special problems. Examples are long grades, passing or no-passing zones, a falling rocks area, or winding roads. Be alert to these and take appropriate action.


Here are some tips for winter driving: (cid:127) Have your vehicle in good shape for winter. (cid:127) You may want to put winter emergency supplies in


your vehicle.


Also see Tires on page 5-47.


4-27


Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and a couple of reflective warning triangles. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet, or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle. Driving on Snow or Ice Most of the time, those places where your tires meet the road probably have good traction. However, if there is snow or ice between your tires and the road, you can have a very slippery situation. You will have a lot less traction, or grip, and will need to be very careful.


4-28


What is the worst time for this? Wet ice. Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it is about freezing (32°F; 0°C) and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition — smooth ice, packed, blowing or loose snow — drive with caution.


If you have traction control, keep the system on. It will improve your ability to accelerate when driving on a slippery road. But you can turn the traction system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud, ice, or snow. See If You Are Stuck: In Sand, Mud, Ice or Snow on page 4-32. Even though your vehicle has a traction system you will want to slow down and adjust your driving to the road conditions. See Traction Control System (TCS) on page 4-10. If you do not have a traction system, accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. Unless you have the anti-lock braking system, you will want to brake very gently, too. If you do have anti-lock, see Anti-Lock Brake System (ABS) on page 4-8. This system improves your vehicle’s stability when you make a hard stop on a slippery road.) Whether you have the anti-lock braking system or not, you will want to begin stopping sooner than you would on dry pavement. Without anti-lock brakes, if you feel your vehicle begin to slide, let up on the brakes a little. Push the brake pedal down steadily to get the most traction you can.


Remember, unless you have anti-lock, if you brake so hard that your wheels stop rolling, you will just slide. Brake so your wheels always keep rolling and you can still steer. (cid:127) Whatever your braking system, allow greater


following distance on any slippery road.


(cid:127) Watch for slippery spots. The road might be fine


until you hit a spot that is covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun can not reach: around clumps of trees, behind buildings, or under bridges. Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it. Try not to brake while you are actually on the ice, and avoid sudden steering maneuvers.


4-29


If You Are Caught in a Blizzard


(cid:127) Put on extra clothing or wrap a blanket around you.


If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats — anything you can wrap around yourself or tuck under your clothing to keep warm.


If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe:


Turn on your hazard flashers. Tie a red cloth to your vehicle to alert police that you have been stopped by the snow.


4-30


You can run the engine to keep warm, but be careful.


(cid:127) (cid:127) {CAUTION:


Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can not see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And check around again from time to time to be sure snow does not collect there. Open a window just a little on the side of the vehicle that is away from the wind. This will help keep CO out.


Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged. You will need a well-charged battery to restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for a while. Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.


4-31


If You Are Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you do not want to spin your wheels too fast. The method known as rocking can help you get out when you are stuck, but you must use caution.


{CAUTION:


If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you are stuck, spin the wheels as little as possible. Do not spin the wheels above 35 mph (55 km/h) as shown on the speedometer.


Notice: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle. See Rocking Your Vehicle to Get It Out on page 4-32. For information about using tire chains on your vehicle, see Tire Chains on page 5-60.


Rocking Your Vehicle to Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If your vehicle has traction control, you should turn your traction control system off. See Traction Control System (TCS) on page 4-10. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. By slowly spinning your wheels in the forward and reverse directions, you will cause a rocking motion that may free your vehicle. If that does not get you out after a few tries, you may need to be towed out. If you do need to be towed out, see Towing Your Vehicle on page 4-38.

Tire and Loading Information Label


Loading Your Vehicle It is very important to know how much weight your vehicle can carry. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Vehicle Certification label.


{CAUTION:


Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle.


United States version shown, Canada similar


The Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar). With the driver’s door open, you will find the label attached below the door lock post (striker). The tire and loading information label lists the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. The Tire and Loading Information label also lists the tire size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation, see Tires on page 5-47 and Inflation - Tire Pressure on page 5-53.


4-33


If your vehicle does not have the Tire and Loading Information label, the Certification/Tire label shows the tire size and recommended inflation pressures needed to obtain the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certification/Tire Label” later in this section. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of


occupants and cargo should never exceed XXX kg or XXX pounds” on your vehicle’s placard.


2. Determine the combined weight of the driver and


passengers that will be riding in your vehicle.


3. Subtract the combined weight of the driver and


passengers from XXX kilograms or XXX pounds.


4. The resulting figure equals the available amount of


cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400 − 750 (5 x 150) = 650 lbs.).


5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.


6. If your vehicle will be towing a trailer, the load from


your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity for your vehicle.


If your vehicle can tow a trailer, see Towing a Trailer on page 4-39 for important information on towing a trailer, towing safety rules, and trailering tips.

The Certification/Tire label is found on the rear edge of the driver’s door. The label shows the size of your original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle. This is called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo.

Refer to your vehicle’s tire and loading information label for specific information about your vehicle’s maximum vehicle capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s maximum vehicle capacity weight.


4-36


The Certification/Tire label also tells you the maximum weights for the front and rear axles, called the Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle or the GAWR for either the front or rear axle.


{CAUTION:


Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle.


Notice: Overloading your vehicle may cause damage. Repairs would not be covered by your warranty. Do not overload your vehicle.


If you put things inside your vehicle – like suitcases, tools, packages, or anything else – they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going.


{CAUTION:


Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash.


(cid:127) Put things in the cargo area of your


vehicle. Try to spread the weight evenly.


(cid:127) Never stack heavier things, like suitcases,


inside the vehicle so that some of them are above the tops of the seats.


(cid:127) Do not leave an unsecured child restraint


in your vehicle.


(cid:127) When you carry something inside the vehicle, secure it whenever you can.


(cid:127) Do not leave a seat folded down unless


you need to.

Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-6. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see “Recreational Vehicle Towing” following.


Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as “dinghy towing” (towing your vehicle with all four wheels on the ground) and “dolly towing” (towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”). With the proper preparation and equipment, many vehicles can be towed in these ways. See “Dinghy Towing” and “Dolly Towing,” following. Here are some important things to consider before you do recreational vehicle towing: (cid:127) What’s the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer’s recommendations.


4-38


(cid:127) How far will you tow? Some vehicles have


restrictions on how far and how long they can tow.


(cid:127) Do you have the proper towing equipment? See your dealer or trailering professional for additional advice and equipment recommendations. Is your vehicle ready to be towed? Just as you would prepare your vehicle for a long trip, you’ll want to make sure your vehicle is prepared to be towed. See Before Leaving on a Long Trip on page 4-24.


Dinghy Towing Your vehicle was not designed to be towed with all of its wheels on the ground. If you have a two-wheel-drive vehicle, it can be towed with two of its wheels on the ground. See “Dolly Towing” following. If you have an all-wheel-drive vehicle, it cannot be towed with any of its wheels on the ground. It can be towed with the car carrier equipment. Notice: Towing an all-wheel-drive vehicle with all four wheels on the ground, or even with only two of its wheels on the ground, will damage drivetrain components. Do not tow an all-wheel-drive vehicle if any of its wheels will be on the ground.


(cid:127) Dolly Towing If you have a two-wheel-drive vehicle, it can be towed with two of its wheels on the ground. To dolly tow your vehicle, do the following: 1. Put the front wheels on a dolly. 2. Put the vehicle in PARK (P). 3. Set the parking brake and then remove the key. 4. Clamp the steering wheel in a straight-ahead


position with a clamping device designed for towing.


5. Release the parking brake. If you have an all-wheel-drive vehicle, it cannot be towed with any of its wheels on the ground. It can be towed with car carrier equipment. Notice: Towing an all-wheel-drive vehicle with all four wheels on the ground, or even with only two of its wheels on the ground, will damage drivetrain components. Do not tow an all-wheel-drive vehicle if any of its wheels will be on the ground.


Towing a Trailer


{CAUTION:


If you do not use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well — or even at all. You and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle.


Notice: Pulling a trailer improperly can damage your vehicle and result in costly repairs that would not be covered by your warranty. Always follow the instructions in this section and check with your dealer for more information about towing a trailer with your vehicle. Your vehicle can tow a trailer. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. But trailering is different than just driving your vehicle by itself.


4-39


Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That is the reason for this section. In it are many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer. Load-pulling components such as the engine, transaxle, wheel assemblies and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. The trailer also adds considerably to wind resistance, increasing the pulling requirements. If You Do Decide To Pull A Trailer If you do, here are some important points:


There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you will be driving. A good source for this information can be state or provincial police. (cid:127) Consider using a sway control. See “Hitches” later in


this section.


4-40


(cid:127) Do not tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged.


(cid:127) During the first 500 miles (800 km) that you tow a trailer, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads.


(cid:127) You can use L4 or, as you need to, a lower gear


when towing a trailer. Operating your vehicle in L4 when towing a trailer will minimize heat buildup and extend the life of your transaxle.


Three important considerations have to do with weight: (cid:127) Weight of the trailer (cid:127) Weight of the trailer tongue (cid:127) Weight on your vehicle’s tires Weight of the Trailer How heavy can a trailer safely be? If you have the trailer towing package, your vehicle can tow up to 2,900 lbs. (1 300 kg) with up to five occupants or up to 3,500 lbs. (1 575 kg) with up to two occupants. But even that can be too heavy.


(cid:127) It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. You can ask your dealer for our trailering information or advice, or you can write us at:

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. If you have a lot of options, passengers, or cargo in the vehicle, it will reduce the tongue weight your vehicle can carry, which will also reduce the trailer


weight your vehicle can tow. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading Your Vehicle on page 4-33 for more information about your vehicle’s maximum load capacity.


If you are using a weight-carrying or a weight-distributing hitch, the trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight (B). Do not exceed the maximum allowable tongue weight for your vehicle. After you have loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, you may be able to get them right simply by moving some items around in the trailer.


4-41


Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground. Trailer Brakes If your trailer weighs more than 1,000 lbs. (450 kg) loaded, then it needs its own brakes – and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you will be able to install, adjust and maintain them properly. Because your vehicle may have anti-lock brakes, do not try to tap into your vehicle’s brake system. If you do, both brake systems will not work well, or at all.


Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the upper limit for cold tires. You will find these numbers on the Certification/Tire Label at the rear edge of the driver’s door, or see Loading Your Vehicle on page 4-33. Then be sure you do not go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow:


If you will be pulling a trailer that, when loaded, will weigh more than 2,000 lbs. (900 kg), be sure to use a properly mounted, weight-carrying hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving.


(cid:127) Will you have to make any holes in the body of


your vehicle when you install a trailer hitch? If you do, remember to seal the holes when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-24. Dirt and water can, too.


4-42


(cid:127) Driving with a Trailer


{CAUTION:


If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You can not see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-24. To maximize your safety when towing a trailer:


(cid:127) Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip.


(cid:127) Keep the rear-most windows closed.


If exhaust does come into your vehicle through a window in the rear or another opening, drive with your front, main heating or cooling system on and with the fan on any speed. This will bring fresh, outside air into your vehicle. Do not use the climate control setting for maximum air because it only recirculates the air inside your vehicle. See Climate Control System on page 3-18.


Towing a trailer requires a certain amount of experience. Before setting out for the open road, you will want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns.


4-43


(cid:127) Passing You will need more passing distance up ahead when you are towing a trailer. And, because you are a good deal longer, you will need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you are turning with a trailer, make wider turns than normal. Do this so your trailer will not strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.


Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have extra wiring. The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you are about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you do not shift down, you might have to use your brakes so much that they would get hot and no longer work well. If you are towing a trailer that weighs more than 1,000 lbs. (450 kg), drive in L4 instead of AUTOMATIC OVERDRIVE (D) or, as you need to, a lower gear. This will minimize heat build-up and extend the life of your transaxle.


4-44


Parking on Hills


{CAUTION:


You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged.


But if you ever have to park your rig on a hill, do the following: 1. Apply your regular brakes, but do not shift into


PARK (P) yet.


2. Have someone place chocks under the


trailer wheels.


3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.


4. Reapply the regular brakes. Then apply your


parking brake, and then shift to PARK (P).


5. Release the regular brakes.


When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down


while you do the following: (cid:127) Start your engine. (cid:127) Shift into a gear. (cid:127) Release the parking brake.


2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store


the chocks.


Maintenance When Trailer Towing Your vehicle will need service more often when you are pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid, engine oil, belts, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly. If you are trailering, it is a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.

You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See Maintenance Record on page 6-15.


{CAUTION:


You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it.


(cid:127) Be sure you have sufficient knowledge,


experience, the proper replacement parts and tools before you attempt any vehicle maintenance task.


(cid:127) Be sure to use the proper nuts, bolts and


other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.


Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle. Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle.


5-4


Gasoline Octane Use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher-octane fuel is necessary. If you are using 87 octane or higher-octane fuel and hear heavy knocking, your engine needs service.


Gasoline Specifications It is recommended that gasoline meet specifications which were developed by automobile manufacturers around the world and contained in the World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org/fuel_charter.htm. Gasoline meeting these specifications could provide improved driveability and emission control system performance compared to other gasoline.


5-5


California Fuel If your vehicle is certified to meet California Emission Standards (see the underhood emission control label), it is designed to operate on fuels that meet California specifications. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on and your vehicle may fail a smog-check test. See Malfunction Indicator Lamp on page 3-30. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty.


Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. General Motors recommends that you buy gasolines that are advertised to help keep fuel injectors and intake valves clean. If your vehicle experiences problems due to dirty injectors or valves, try a different brand of gasoline. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the specifications described earlier.


5-6


Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage would not be covered under your warranty. Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service.


Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.


5-7


Filling Your Tank


{CAUTION:


Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, flames and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle — this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel.


5-8


The tethered fuel cap is located behind a hinged fuel door on the passenger’s side of the vehicle. To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right.


{CAUTION:


{CAUTION:


If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.


If you need a new fuel cap, be sure to get


Notice: the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See Malfunction Indicator Lamp on page 3-30.


If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.


Be careful not to spill fuel. Do not top off or overfill the tank and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-75. When replacing the fuel cap, turn it to the right (clockwise) until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 3-30.

Checking Things Under the Hood


Hood Release To open the hood, do the following:


1. Pull the handle located


inside the vehicle.


Filling a Portable Fuel Container


{CAUTION:


Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others:


(cid:127) Dispense gasoline only into


approved containers.


(cid:127) Do not fill a container while it is inside a


vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground. (cid:127) Bring the fill nozzle in contact with the


inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete.


(cid:127) Do not smoke while pumping gasoline.

Engine Oil Checking Engine Oil It is a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 5-12 for the location of the engine oil dipstick.


Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.


When to Add Engine Oil If the oil is at or below the cross-hatched area at the tip of the dipstick, then you will need to add at least one quart of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-84. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged.


5-13


See Engine Compartment Overview on page 5-12 for the location of the engine oil fill cap.


SAE 5W-30 may not appear on all caps.


Be sure to add enough oil to put the level somewhere in the proper operating range in the cross-hatched area. Push the dipstick all the way back in when you are through. What Kind of Engine Oil to Use Look for two things: (cid:127) GM6094M


Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M.


5-14


(cid:127) SAE 5W-30


As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, if it is going to be 0°F (–18°C) or above and SAE 5W-30 is not available, you may use SAE 10W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.


Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).


You should look for this information on the oil container, and use only those oils that are identified as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container.


Notice: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. GM Goodwrench® oil meets all the requirements for your vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol meet GM Standard GM6094M are all you will need for good performance and engine protection.

How to Reset the Change Engine Oil Light The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a change engine oil light being turned on, reset the system. 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal three


times within five seconds. The change engine oil light will flash while the system is resetting.


3. Turn the key to LOCK. If the change engine oil light comes back on and stays on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.


Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A change engine oil light will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer has GM-trained people who will perform this work using genuine GM parts and reset the system. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed.


5-16


What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.


Engine Air Cleaner/Filter When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at every oil change and replace at the first oil change after 25,000 miles (40,000 km). How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. The engine air cleaner/filter is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12
for more information on location.


5-17


See Scheduled Maintenance on page 6-4 for information on when to replace the engine air cleaner/filter.


To replace the engine air cleaner/filter, do the following: 1. Turn off the engine.


{CAUTION:


Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it helps to stop flame if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off.


If the air cleaner/filter is off, a backfire can


Notice: cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you are driving.


5-18


2. Disconnect the air flow sensor electrical connector.


3. Disconnect the crank case ventilation tube.


4. Loosen the screws on the clamps holding the air


outlet duct in place. Do not pry the clamps off.


5. Remove the air outlet duct.


5-19


7. Inspect or replace the engine air cleaner/filter.


If the air filter element is dirty, you should replace it. If it is only dusty, it may be cleaned by blowing compressed air through it from the clean side. Make sure you are away from the engine compartment when cleaning the air filter with compressed air. Wipe all dust from inside of the housing and inspect the air cleaner and air outlet duct for cracks, cuts and deterioration. The air outlet duct must be replaced if damaged.


8. Reinstall the filter cover and latch the clamps. 9. Reattach the air outlet duct and tighten the screws


on the clamps that hold the duct in place. 10. Reconnect the crank case ventilation tube. 11. Reconnect the air flow sensor electrical connector.


6. Undo the clamps on the filter cover. To remove the cover, pull up on the front and then pull the cover out.


5-20


Automatic Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, have the vehicle repaired as soon as possible. You may also have your fluid level checked when you have your oil changed. Change both the fluid and filter every 50,000 miles (83 000 km) if the vehicle is mainly driven under one or more of these conditions:


In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. In hilly or mountainous terrain.


(cid:127) When doing frequent trailer towing. (cid:127) Uses such as found in taxi, police or


delivery service.


If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing. Notice: Using any transaxle fluid other than T-IV Transaxle Fluid will result in transaxle damage. Damage caused by the use of fluid other than T-IV Transaxle Fluid will not be covered by your warranty. Use only T-IV Transaxle Fluid.


Engine Coolant The cooling system in your vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for five years or 100,000 miles (166 000 km), whichever occurs first, if you add only DEX-COOL® extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see Engine Overheating on page 5-24. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: (cid:127) Give freezing protection down to −34°F (−37°C). (cid:127) Give boiling protection up to 265°F (129°C). (cid:127) Protect against rust and corrosion. (cid:127) Help keep the proper engine temperature. Let the warning lights and gages work as they should.


Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core or radiator corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX-COOL® (silicate-free) coolant in your vehicle.
