Cleaning the DVD Player When cleaning the outside DVD faceplate and buttons, use only a clean cloth dampened with clean water. Cleaning the Video Screen When cleaning the video screen, use only a clean cloth dampened with clean water. Use care when directly touching or cleaning the screen, as damage may result. Rear Seat Audio (RSA) If your vehicle has rear seat audio (RSA), this feature allows rear seat passengers to listen to and control any of the following audio sources: AM/FM tuner, front CD player, and XM™ Satellite Radio Service (if equipped). However, the rear seat passengers can only control the sources that the front seat passengers are not listening to. For example, rear seat passengers may listen to and control a CD through headphones while the driver listens to the radio through the front speakers. The rear seat passengers have control of the volume for each set of headphones. The front seat audio controls always have priority over the RSA controls. If the front seat passengers switch the source for the main radio to a remote source, the RSA will not be able to control the remote source. You can operate the RSA when the main radio is off. The DVD or auxiliary device will always be available on channel (CHA or CH1) of the wireless headphones. All other RSA sources are available on CHB or CH2 of the wireless and wired headphones. If the RSA is off, the wired headphones will provide DVD or auxiliary device audio. You will not be able to listen to XM, on CHB or CH2, if you are listening to a DVD or an auxiliary device on CHB or CH2 and vice versa. The remote control will not operate any of the RSA features. 3-109 BAND: Press this button to switch between FM1, FM2, AM, or XM1 or XM2 (if equipped). The selected radio station will appear on the display. If the front passengers are listening to the radio, the RSA will not switch between the bands and cannot change the station. tr / [ u (Tune): When listening to the radio, press the right or the left arrow to go to the next or the previous station and stay there. This function is inactive if the front seat passengers are listening to the radio. When a CD is playing, press the left arrow to go to the start of the current track or to the previous track. Press the right arrow to go to the next track on the CD. This function is inactive if the front seat passengers are listening to a CD. PROG (Program): Press this button to select the next preset station stored on the radio. Each press of this button will take you to the next preset station. This function is inactive if the front seat passengers are listening to the radio. O (Power): Press this button to turn the system on or off. RSA CHB or RSA CH2 will appear on the display when the system is on to indicate the channel to receive audio for the wireless headphones. Press this button when the system is on to silence the rear speakers. Press this button again to turn the sound back on. 3-110 When a CD is playing in the single CD player, press this button to select the next track. This function is inactive if the front seat passengers are listening to a CD. When a CD is playing in the six-disc CD changer, press this button to select the next CD, if multiple CDs are loaded. This function is inactive if the front seat passengers are listening to a CD. SRCE (Source): Press this button to switch between playing the AM/FM tuner, front CD player, and XM™ Satellite Radio Service (if equipped). If one of the sources are not loaded, the system will skip over the source when this button is pressed. X (Headphone): Press the right or the left headphone button to enable volume control of the wired headphone connected to the corresponding jack. Press the right and left arrow buttons to change the volume. rj (Parental Control): This button is located behind the video screen, below the auxiliary jacks. Press this button while using RSA, or when a DVD or CD is playing to blank the video screen and to mute the audio. The power indicator lights on the DVD player will ﬂash. Turning on the parental control will also disable all other button operations from the remote control and the DVD player, except for the eject button. Press this button again to restore operation of the RSA, DVD player, and remote control. This button may also be used to turn the DVD player power on and automatically resume play if the vehicle is on and a disc is in the player. If no disc is in the player then the system will power up in auxiliary mode. 3-111 Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identiﬁcation Number (VIN). If the radio is moved to a different vehicle, it will not operate and LOCKED will appear on the display. With THEFTLOCK® activated, the radio will not operate if stolen. Audio Steering Wheel Controls They include the following: wt u x (Seek): Press the up or the down arrow to go to the next or previous station and stay there. To scan stations, press and hold either arrow for two seconds until FREQUENCY SCAN appears on the display. The radio will go to a station, play for a few seconds, then go to the next station. Press either arrow again to stop scanning. The sound will mute while seeking or scanning. The radio will only seek or scan stations with a strong signal that are in the selected band. When a CD is playing, press either arrow to go to the previous or next track, if more than eight seconds have played. If either arrow is held or pressed more than once, the player will continue moving backward or forward through the CD. If your vehicle has this feature, some audio controls can be adjusted at the steering wheel. 3-112 BAND: Press this button to switch between FM1, FM2, AM, or XM1 or XM2 (if equipped). 1 - 6: Press this button to scan the stations that are programmed on the radio preset pushbuttons. The radio will go to the next preset station stored on the pushbuttons, play for a few seconds, then go on to the next preset station. Press this button again to stop scanning. The radio will only scan preset stations with a strong signal that are in the selected band. $ (Mute): Press this button to silence the system. Press this button again, to turn the sound on. r (Play): When listening to the radio, press this button to play a cassette tape or CD. wu x (Volume): Press the up or down arrow to increase or decrease the volume. Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. Static can occur on AM stations caused by things like storms and power lines. Try reducing the treble to reduce this noise. FM Stereo FM stereo will give the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to fade in and out. XM™ Satellite Radio Service XM™ Satellite Radio Service gives digital radio reception from coast to coast. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. The radio may display NO SIGNAL to indicate interference. 3-113 Care of Your CDs and DVDs Handle discs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge. Be sure never to touch the side without writing when handling discs. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge. Care of Your CD and DVD Player The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism. Fixed Mast Antenna The ﬁxed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, straighten it out by hand. If the mast is badly bent, replace it. Check occasionally to make sure the mast is still tightened to the antenna base located on the hood of the vehicle. If tightening is required, tighten by hand. XM™ Satellite Radio Antenna System The XM™ Satellite Radio antenna is located on the roof of your vehicle. Keep this antenna clear of snow and ice build up for clear radio reception. Loading items onto the roof of your vehicle can interfere with the performance of the XM™ system. Make sure that the XM™ satellite antenna is not obstructed. 3-114 Section 4 Driving Your Vehicle Your Driving, the Road, and Your Vehicle ..........4-2 Defensive Driving ...........................................4-2 Drunken Driving .............................................4-2 Control of a Vehicle ........................................4-6 Braking .........................................................4-6 Anti-Lock Brake System (ABS) .........................4-7 Braking in Emergencies ...................................4-8 Traction Control System (TCS) .........................4-9 StabiliTrak® System ......................................4-10 All-Wheel Drive (AWD) System .......................4-12 Steering ......................................................4-13 Off-Road Recovery .......................................4-15 Passing .......................................................4-15 Loss of Control .............................................4-17 Driving at Night ............................................4-18 Driving in Rain and on Wet Roads ..................4-20 City Driving ..................................................4-23 Freeway Driving ...........................................4-24 Before Leaving on a Long Trip .......................4-25 Highway Hypnosis ........................................4-26 Hill and Mountain Roads ................................4-26 Winter Driving ..............................................4-28 If Your Vehicle is Stuck in Sand, Mud, Ice or Snow ..............................................4-32 Rocking Your Vehicle to Get It Out .................4-33 Loading Your Vehicle ....................................4-33 Towing ..........................................................4-39 Towing Your Vehicle .....................................4-39 Recreational Vehicle Towing ...........................4-39 Level Control ...............................................4-40 Towing a Trailer ...........................................4-41 4-1 Your Driving, the Road, and Your Vehicle Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See Safety Belts: They Are for Everyone on page 1-22. Defensive driving really means “be ready for anything.” On city streets, rural roads, or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It is the best defensive driving maneuver, in both city and rural driving. You never know when the vehicle in front of you is going to brake or turn suddenly. Defensive driving requires that a driver concentrate on the driving task. Anything that distracts from the driving task — such as concentrating on a cellular telephone call, reading, or reaching for something on the ﬂoor — makes proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do things like this, or pull off the road in a safe place to do them yourself. These simple defensive driving techniques could save your life. Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: Judgment (cid:127) Muscular Coordination (cid:127) Vision (cid:127) Attentiveness 4-2 (cid:127) Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 16,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with more than 300,000 people injured. Many adults — by some estimates, nearly half the adult population — choose never to drink alcohol, so they never drive after drinking. For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological and developmental reasons for these laws. The obvious way to eliminate the leading highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is “too much” if someone plans to drive? It is a lot less than many might think. Although it depends on each person and situation, here is some general information on the problem. The Blood Alcohol Concentration (BAC) of someone who is drinking depends upon four things: The amount of alcohol consumed The drinker’s body weight The amount of food that is consumed before and during drinking The length of time it has taken the drinker to consume the alcohol 4-3 (cid:127) (cid:127) (cid:127) (cid:127) According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin, or vodka. 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. The law in most U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.10 percent after three to six drinks (in one hour). Of course, as we have seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them. 4-4 But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision. At a BAC level of 0.10 percent, the chance of this driver having a collision is 12 times greater; at a 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. 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. 4-5 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. 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 three-fourths 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 three-fourths 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, whether it is wet, dry, or 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. 4-6 Anti-Lock Brake System (ABS) Your vehicle has anti-lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid. When you start your engine and 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. If there is a problem with the anti-lock brake system, this warning light will stay on. See Anti-Lock Brake System Warning Light on page 3-38. 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. 4-7 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. 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 With anti-lock brakes, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. 4-8 Traction Control System (TCS) Your vehicle may have a traction control system that limits wheel spin. This is especially useful in slippery road conditions. On a front-wheel-drive vehicle, the system operates if it senses that one or both of the front wheels are spinning or beginning to lose traction. On an all-wheel-drive vehicle, the system will operate if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, the system brakes the spinning wheel(s) and/or reduces engine power to limit wheel spin. The TRACTION CONTROL ACTIVE message will come on in the Driver Information Center (DIC) when the traction control system is limiting wheel spin. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re-engage the cruise control. This warning light will come on to let you know if there is a problem with your traction control system. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the SERVICE TRACTION SYSTEM message in the CIB comes on and stays on or comes on while you are driving, there’s a problem with your traction control system. Have the traction control system serviced by your GM dealer as soon as possible. When this warning message is on, the TRACTION CONTROL OFF message in the CIB will come on to remind you that the system will not limit wheel spin. Adjust your driving accordingly. 4-9 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 or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 4-33 and If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-32. To turn the system off, press the traction control button located on the center of the instrument panel. If the system is limiting wheel spin when you press the button, the TRACTION CONTROL ACTIVE message will go off, but the system will not turn off until there is no longer a current need to limit wheel spin. The TRACTION CONTROL OFF message will come on to remind you the system is off. You can turn the system back on at any time by pressing the button again. The traction control system warning message should go off. 4-10 StabiliTrak® System Your vehicle may be equipped with StabiliTrak® which combines anti-lock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions. When you ﬁrst start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If the system fails to turn on or activate, the SERVICE STABILITY SYSTEM message will be displayed on the Driver Information Center (DIC). If the vehicle has gone through heavy acceleration or braking or multiple turns during the ﬁrst two miles of driving after starting your vehicle, the STABILITY CONTROL OFF message may appear on the DIC. If this is the case, your vehicle does not need servicing. You will need to turn the vehicle off and then restart it to initialize StabiliTrak®. If either message appears on the DIC, and your vehicle has not gone through hard acceleration, braking or multiple turns in the ﬁrst two miles of driving, your vehicle should be taken in for service. The STABILITY CONTROL ACTIVE message will appear on the DIC only when the system is both on and activated. It means that an advanced computer-controlled system has come on to help your vehicle continue to go in the direction in which you are steering. StabiliTrak® activates when the computer senses that your vehicle is just starting to spin, as it might if you hit a patch of ice or other slippery spot on the road. When the system activates, you may hear a noise or feel a vibration in the brake pedal. This is normal. When the STABILITY CONTROL ACTIVE message is on, you should continue to steer in the direction you want to go. The system is designed to help you in bad weather or other difficult driving situations by making the most of whatever road conditions will permit. For more information on the stability messages, see Driver Information Center (DIC) on page 3-45. If the StabiliTrak® system turns off, the traction control system warning light will illuminate, and the STABILITY CONTROL OFF message will appear on the DIC to warn the driver that StabiliTrak® is no longer available to assist you with directional control of the vehicle. Adjust your driving accordingly. To limit wheel spin and realize the full beneﬁts of the stability enhancement system, you should normally leave traction control on, but it may be necessary to turn the system off if your vehicle is stuck in sand, mud, ice or snow, and you want to “rock” your vehicle to attempt to free it. See Rocking Your Vehicle to Get It Out on page 4-33 and If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-32. Traction Control Operation The traction control system is part of the StabiliTrak® system. Traction control limits wheel spin by reducing engine power to the wheels (engine speed management) and by applying brakes to each individual wheel (brake-traction control) as necessary. The traction control system is enabled automatically when you start your vehicle. It will activate and display the TRACTION CONTROL ACTIVE message in the DIC if it senses that any of the wheels are spinning or beginning to lose traction while driving an all-wheel-drive vehicle, or if one or both of the front wheels are spinning or beginning to lose traction while driving a front-wheel-drive vehicle. 4-11 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. 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 brake traction-control system activates constantly or if the brakes have heated up due to high-speed braking, brake traction-control will be disabled and the TRACTION CONTROL ACTIVE message will be displayed. In the limited mode, the traction control system will only use engine traction-control and is limited in its ability to provide optimal performance since the system will not utilize brake traction-control to control slip on the drive wheels. The system will return to normal operation after the brakes have cooled. This can take up to two minutes or longer depending on brake usage. The traction control system may activate on dry or rough roads or under conditions such as heavy acceleration while turning or abrupt upshifts/downshifts of the transmission. When this happens you may notice a reduction in acceleration, or may hear a noise or vibration. This is normal. If your vehicle is in cruise control when the system activates, the STABILITY CONTROL ACTIVE message will appear on the DIC and the cruise control will automatically disengage. When road conditions allow you to use cruise again, you may re-engage the cruise control. See Cruise Control on page 3-10. StabiliTrak® may also turn off automatically if it determines that a problem exists with the system. If the problem does not clear itself after restarting the vehicle, you should see your dealer for service. 4-12 Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. 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. 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 4-9. 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. 4-13 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 cannot; 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. See Braking on page 4-6. 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. 4-14 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. 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. 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. 4-15 (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. (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. 4-16 (cid:127) (cid:127) (cid:127) 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. A cornering skid is best handled by easing your foot off the accelerator pedal. If you have the Traction Control System (TCS), remember: It helps avoid only the acceleration skid. See Traction Control System (TCS) on page 4-9. 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. 4-17 Driving at Night 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 (ABS), remember: It helps avoid only the braking skid. If you do not have ABS, 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. 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 cannot 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. You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to re-adjust 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. 4-19 (cid:127) (cid:127) Driving in Rain and on Wet Roads 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. Rain and wet roads can mean driving trouble. On a wet road, you cannot 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. 4-20 {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. 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 cannot avoid deep puddles or standing water, drive through them very slowly. 4-21 Driving Through Flowing Water Some Other Rainy Weather Tips {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. 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 5-51. 4-22 (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 4-24. 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. 4-23 (cid:127) (cid:127) 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. 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. 4-24 Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. 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. 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? 4-25 (cid:127) (cid:127) (cid:127) Hill and Mountain Roads Driving on steep hills or mountains is different from driving in ﬂat or rolling terrain. 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. 4-26 (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. (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. 4-27 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 5-51. 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. Winter Driving 4-28 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. 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 the traction control system (TCS), it will improve your ability to accelerate when driving on a slippery road. But you can turn the TCS off if you ever need to. You should turn the TCS off if your vehicle ever gets stuck in sand, mud, ice, or snow. See If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-32. Even though your vehicle has TCS, you will want to slow down and adjust your driving to the road conditions. Under certain conditions, you may want to turn the TCS off, such as when driving through deep snow and loose gravel, to help maintain vehicle motion at lower speeds. See Traction Control System (TCS) on page 4-9. If you do not have TCS, 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. 4-29 If You Are Caught in a Blizzard 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. (cid:127) Put on extra clothing or wrap a blanket around you. If you do not have 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. Unless you have the anti-lock braking system (ABS), you will want to brake very gently, too. If you do have ABS, see Anti-Lock Brake System (ABS) on page 4-7. ABS improves your vehicle’s stability when you make a hard stop on a slippery road. Whether you have ABS or not, you will want to begin stopping sooner than you would on dry pavement. Without ABS, 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 ABS, 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 cannot reach, such as 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. 4-30 (cid:127) (cid:127) You can run the engine to keep warm, but be careful. {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 cannot 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. 4-31 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. If Your Vehicle is 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 4-33. For information about using tire chains on your vehicle, see Tire Chains on page 5-64. 4-32 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 4-9. 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 4-39. Loading Your Vehicle It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Certiﬁcation/Tire label. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (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. 4-33 The Tire and Loading Information label also shows the 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 5-51 and Inﬂation - Tire Pressure on page 5-57. There is also important loading information on the vehicle Certiﬁcation/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. 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. Tire and Loading Information Label Example Label A vehicle speciﬁc Tire and Loading Information label is attached to the center pillar (B-pillar) of your vehicle. With the driver’s door open, you will ﬁnd the label attached below the door lock post (striker). The tire and loading information label shows the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. 4-34 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. See Towing a Trailer on page 4-41 for important information on towing a trailer, towing safety rules, and trailering tips. Example 1 Item Description Total Vehicle Capacity Weight for Example 1 = Subtract Occupant Weight 150 lbs (68 kg) × 2 = Available Occupant and Cargo Weight = 1,000 lbs (453 kg) 300 lbs (136 kg) 700 lbs (317 kg) 4-35 Example 2 Example 3 Item Description Total Item Description Total 1,000 lbs (453 kg) Vehicle Capacity Weight for Example 2 = Subtract Occupant Weight 150 lbs (68 kg) × 5 = Available Cargo Weight = 250 lbs (113 kg) 750 lbs (340 kg) 1,000 lbs (453 kg) Vehicle Capacity Weight for Example 3 = Subtract Occupant Weight 200 lbs (91 kg) × 5 = Available Cargo Weight = 0 lbs (0 kg) 1,000 lbs (453 kg) Refer to your vehicle’s tire and loading information label for speciﬁc information about your vehicle’s capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s capacity weight. 4-36 Certiﬁcation/Tire Label The label shows 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. 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. A vehicle speciﬁc Certiﬁcation/Tire label is attached to the rear edge of the driver’s door. 4-37 Never exceed the GVWR for your vehicle or the GAWR for either the front or rear axle. {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. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (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. 4-38 Towing 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 know 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. (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 4-25. 4-39 (cid:127) 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 the two rear 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 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. Dolly Towing If you have a two-wheel-drive vehicle, it can be towed with its two rear 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. Level Control On vehicles equipped with automatic level control, the rear of the vehicle is automatically kept level as you load or unload your vehicle. However, you should still not exceed the GVWR or the GAWR. See Loading Your Vehicle on page 4-33. You may hear the compressor operating when you load or unload your vehicle, and periodically as the system self-adjusts. This is normal. The compressor should operate for brief periods of time. If the sound continues for an extended period of time, your vehicle needs service. Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. 4-40 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. 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. 4-41 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? 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. Look in the following chart to ﬁnd the maximum trailer weight for your vehicle. 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’ll 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. (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 THIRD (3) or, as you need to, a lower gear when towing a trailer. Operating your vehicle in THIRD (3) when towing a trailer will minimize heat buildup and extend the life of your transaxle. 4-42 (cid:127) Vehicle Axle Ratio Two-Wheel-Drive (Short Wheel Base) Two-Wheel-Drive (Long Wheel Base) All-Wheel Drive 3.29 3.29 3.29 Maximum Trailer Weight *GCWR 2,000 lbs (907 kg) 7,000 lbs (3 175 kg) 3,500 lbs (1 588 kg) 8,500 lbs (3 856 kg) 3,500 lbs (1 588 kg) 8,500 lbs (3 856 kg) *The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversion. The GCWR for your vehicle should not be exceeded. You can ask your dealer for our trailering information or advice, or you can write us at the address listed in your Warranty and Owner Assistance Information Booklet. In Canada, write to: General Motors of Canada Limited Customer Communication Center, 163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 4-43 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, equipment, passengers, or cargo in your 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. 4-44 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 (350 lbs (159 kg)), 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. 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: The bumpers on your vehicle are not intended for hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper. 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 are 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 later 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 2-41. Dirt and water can, too. 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. 4-45 (cid:127) (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 cannot see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-41. 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 3-25. 4-46 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.
