detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service is required. Light On Steady -- An emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

If the Light Is Flashing The following may prevent more serious damage to your vehicle: 0 Reducing vehicle speed.

Avoiding hard accelerations. 0 Avoiding steep uphill grades. 0 If you are towing a trailer, reduce the amount of

cargo being hauled as soon as it is possible.

If the light stops flashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.

If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Are you low on fuel? As your engine starts to run out of fuel, your engine may not run as efficiently as designed since small amounts of air are sucked into the fuel line causing a misfire. The system can detect this. Adding fuel should correct this condition. Make sure to install the fuel cap properly. It will take a few driving trips to turn the light off. Have you recently changed brands of fuel?

If so, be sure to fuel your vehicle with quality fuel (see “Fuel” in the Index). Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, have your dealer or qualified service center check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.

Oil Pressure Gage

The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).

Don't keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced.

Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. A reading in the low pressure zone may be caused by a dangerously low oil level or other problem causing low oil pressure. Check your oil as soon as possible.

I NOTICE:

Damage to your engine from neglected oil problems can be costly and is not covered by your warranty.

Check Gages Light

Fuel Gage

The CHECK GAGES light will come on briefly when you are starting the engine.

The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank.

CHECK GAGES

If the light comes on and stays on while you are driving, check your coolant temperature and engine oil pressure gages to see if they are in the warning zones.

The gage will first.indicate EMPTY (E) before you are out of fuel, and you should get more fuel as soon as possible.

UNLEADED FUEL ONLY

Listed are four situations you may experience with your fuel gage:

At the gas station, the fuel pump shuts off before the gage reads FULL (F). It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank. The gage moves a little when you turn a corner or speed up. The gage doesn’t go back to EMPTY (E) when you turn off the ignition.

None of these indicate a problem with the fuel gage.

Engine Coolant Temperature Gage

This gage shows the engine coolant temperature. If the gage pointer moves into the red area your engine is too hot!

’%

260

It means that your engine coolant has overheated. If you have been operating your vehicle under normal operating conditions, you should pull off the road, stop your vehicle, and turn off the engine as soon as possible. In “Problems on the Road,” this manual shows what to do. See “Engine Overheating” in the Index.

Voltmeter

When your engine is not running, but the ignition is on (in the RUN position), this gage shows your battery’s state of charge in DC volts.

VOLTS

When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warnir,g zones indicate the normal operating range.

Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Electronic Road-Speed Governor (Gasoline Engines) (Option) This optional system automatically controls vehicle top speed. The system controller receives a signal from the vehicle speed sensor and reduces power when the vehicle speed reaches the maximum 65 mph (105 km/h) governed speed.

Center High-Mounted Stoplamp

If items are loaded on the roof of the vehicle, as in a luggage carrier, care should be taken not to block or damage the center high-mounted stoplamp unit. If you tow a trailer that is equipped with provisions for a center high-mounted stoplamp, see your GM dealer for instructions on how to make it operate with your vehicle’s electrical system. As with any electrical system modification, have the work performed by a qualified electrical service person.

Your vehicle’s center high-mounted stoplamp is located above the rear doors at the center of the vehicle.

Comfort Controls This section tells you how to make your air system work for you. Your comfort control system uses ozone-friendly R- 134a refrigerant. With these systems, you can control the heating, cooling and ventilation in your van. Your vehicle also has a flow-through ventilation system described later in this section. Heater Controls

Fan Knob The left knob of the heating system control panel controls the fan speed. The knob has four speed positions. To increase airflow, move the knob toward HI. To decrease airflow, move it toward LO. To turn the fan off, move the mode knob on the far right to OFF.

Temperature Knob The middle knob panel lets you select the relative temperature of the air flowing into the passenger area of your vehicle. This knob will allow you to adjust the relative air temperature independently of the function knob setting. Move the knob clockwise toward the red area for warmer air. Move the knob counter clockwise toward the blue area for cooler air.

If your vehicle does not have air conditioning, your heater controls will look like this.

the vehicle’s interior reaches a comfortable temperature, move the knob clockwise to place the air conditioning system in the A/C mode. A/C: Use for normal cooling on hot days. This setting cools outside air and directs it through the instrument panel outlets. +e

‘fl BI-LEVEL A/C: Use this setting to divide airflow between the heater floor vents and instrument I,. panel vents. The air conditioning compressor may operate in this setting to cool the air. /J VENT This setting directs air through the instrument panel vents. +H HEAT This setting directs air through the heater we floor vents. This setting is useful for cold weather. +# HEATmEFROST: Use this setting to divide airflow between the heater floor vents and windshield.

DEFROST This setting directs air through the windshield defroster vents. This setting is useful when you have fog or ice on the windshield.

Rear Heater (Without Air Conditioning) If you have a rear heater (without rear air conditioning), the control switch is located on the instrument panel.

Rear Air Conditioning and Rear Heater If your vehicle has a rear air conditioning and rear heater system combination, controls are provided to regulate the temperature, location and speed of the airflow.

To increase and decrease the flow of heated air to the rear floor vents, move the switch marked REAR HEAT to the blower speed you want. The knob has three speed positions. To increase the flow of heated air, move the switch toward HIGH. To turn the fan off, move the switch to OFF.

Front Passenger Control

To adjust the air temperature, turn the temperature knob on the right side of the control panel.

For warmer air, turn the knob clockwise toward the red side, and for cooler air, turn the knob counterclockwise toward the blue side. To regulate the airflow location, adjust the center knob on the control panel. Turn the knob counterclockwise for floor vent airflow or clockwise for headliner vent airflow. Generally, the upper vents are used for air conditioning and the floor vents for heating. The control knob can be set to any blend setting. To adjust the airflow speed, turn the fan control knob on the left side of the control panel to the desired blower setting. To activate the rear control, move the fan knob on the front control to REAR CNTL.

3-6

Rear Passenger Control

The rear control works just like the front control. It will allow second seat passengers to adjust the controls as they desire.

Air Conditioning Before using your vehicle’s air conditioning, open the windows to clear the vehicle of hot air. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work at its best. You can use MAX A/C with the temperature knob in the blue area, when it’s really hot outside and you need to cool the inside air quickly. MAX A/C lets in only a little air from the outside. If you first use MAX A/C, you can then use A/C with the temperature knob in the blue area, as soon as the vehicle has cooled down, so outside air will be going through your vehicle. If your vehicle has rear air conditioning, setting it on LO may enhance front A/C performance by allowing trapped refrigerant in rear lines to circulate. When the air conditioning, DEFROST or BLEND is on, you may notice a slight increase or decrease in engine speed, due to compressor operation. This is normal because the system is designed to cycle the compressor on and off to keep the desired temperature.

Heating On cold days, use HEATER with the temperature knob in the red area. Outside air will be brought in through the floor outlets. The heater works best if you keep your windows closed while using it. If you use the optional engine coolant heater before starting your engine, your heating system will produce warmer air faster to heat the passenger compartment in cold weather. See “Engine Coolant Heater” in the Index. Ventilation Tips

Keep the hood and front air inlet free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. When you enter a vehicle in cold weather, turn the blower fan to HI for a few moments before driving off. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of yow windows.

3-7

0 Keep the air path under the front seats clear of throughout

objects. This helps air to circulate your vehicle.

Your vehicle has air vents in the center and on the sides of your instrument panel. You can move the vents from side to side or up and down to direct the flow of air, or close the vents altogether. When you close a vent, it will increase the flow of air coming out of any vents that are open. Audio Systems Your Delco@ audio system has been designed to operate easily and give years of listening pleasure. You will get the most enjoyment out of it if you acquaint yourself with it first.

Press RECALL again to return to the time display. AM-FM: While in the CD mode, press this button to stop playing the CD and play the radio. The CD symbol will still display but the word CD will be replaced with either AM, FMl or FM2. (If the radio is turned off, the disc stays in the player and will resume playing at the point where it stopped.) CD AUX: To switch between the player and the radio when a disc is playing, press the AM-FM button. To return to the player, press CD AUX. When a disc is playing, the letters CD and the CD symbol will appear on the display. (If the radio is turned off, the disc stays in the player and will resume playing at the point where it stopped.) EJECT Press this button to eject the disc from the player and play the radio. When the same or a new disc is inserted, the disc will start playing on track one. If a compact disc is left sitting in the opening for more than a few seconds, the player will pull the CD back in. The radio will continue playing. When the ignition is off, press this button to load a CD. If you leave a compact disc in the player while listening to the radio, it may become warm.

Playing a Compact Disc in the Single Remote Disc Player (If Equipped)

If you have this option, you can play one compact disc (CD) at a time. To load a CD into the player, hold the disc with the label side up and insert it carefully into the player (approximately halfway). The disc will automatically be pulled into the player. If the radio is off and the ignition is on when a CD is inserted, the radio will turn on and begin playing the CD. It is possible to load and unload CDs with the ignition off. To load a disc with the ignition off, press the EJECT button on the remote player and then insert the disc. To remove the disc, press the EJECT button and remove the disc from the player. A disc that has been ejected but is still sitting in the remote CD player will be pulled back into the player after approximately 30 seconds. This protects the disc

and player from damage. The disc will not start playing. To remove the disc, press the EJECT button and remove the disc from the player. All of the compact disc functions are controlled by the radio buttons except for EJECT. When a disc is in the player, a CD symbol will appear on the display. When a disc is playing, the letters CD will appear next to the CD symbol in the bottom left corner. The track number will also be displayed. If the disc comes back out and ERR appears on the display, it could be that: 0 The disc is upside down. 0 It is dirty, scratched or wet.

There’s too much moisture in the air. (Wait about an hour and try again.) You are driving on a very rough road.

RECALL: Press this button to see what track is currently playing. Press RECALL again within five seconds to see how long the track has been playing. When a new track starts to play, the track number will

also appear. Press RECALL a third time and the time of day will be displayed. TAPE AUX: With a disc loaded in the player and the radio playing, press this button once to play the compact disc. To return to playing the radio, press AM-FM. If both a cassette tape and CD are loaded, press TAPE AUX to switch between the tape and compact disc. EJECT Press this button on the remote player to eject a compact disc. If you leave a compact disc in the player while listening to the radio, it may become warm. Theft-Deterrent Feature THEFTLOCK is designed to discourage theft of your radio. It works by using a secret code to disable all radio functions whenever battery power is removed. The THEFTLOCK feature for the radio may be used or ignored. If ignored, the system plays normally and the radio is not protected by the feature. If THEFTLOCK is activated, your radio will not operate if stolen. When THEFTLOCK is activated, the radio will display LOC to indicate a locked condition anytime battery power is removed. If your battery loses power for any reason, you must unlock the radio with the secret code before it will operate.

Activating the Theft-Deterrent Feature The instructions which follow, explain how to enter your secret code to activate the THEFTLOCK system. It is recommended that you read through all nine steps before starting the procedure. NOTE: If you allow more than 15 sec.onds to elapse between any steps, the radio automatically reverts to time and you must start the procedure over at Step 4. Write down any three or four-digit number from 1. 000 to 1999 and keep it in a safe place separate from the vehicle. Turn the ignition to ACCESSORY or RUN. Turn the radio off. Press the 1 and 4 buttons together. Hold them down until --- shows on the display. Next you will use the secret code number which you have written down. Press MN and 000 will appear on the display. Press MN again to make the last two digits agree with your code. Press HR to make the first one or two digits agree with your code.

Press AM-FM after you have confirmed that the code matches the secret code you have written down. The display will show REP to let you know that you need to repeat Steps 5 through 7 to confirm your secret code. Press AM-FM and this time the display will show SEC to let you know that your radio is secure. The indicator by the volume control will begin flashing when the ignition is turned off.

Unlocking the Theft-Deterrent Feature After a Power Loss Enter your secret code as follows; pause no more than 15 seconds between steps: 1. LOC appears when the ignition is on. 2. Press MN and 000 will appear on the display. 3. Press MN again to make the last two digits agree

with your code.

4. Press HR to make the first one or two digits agree

with your code.

5. Press AM-FM after you have confirmed that the

code matches the secret code you have written down. The display will show SEC, indicating the radio is now operable and secure.

If you enter the wrong code eight times, INOP will appear on the display. You will have to wait an hour with the ignition on before you can try again. When you try again, you will only have three chances to enter the correct code before INOP appears. If you lose or forget your code, contact your dealer. Disabling the Theft-Deterrent Feature Enter your secret code as follows; pause no more than 15 seconds between steps: 1. Turn the ignition to ACCESSORY or RUN. 2. Turn the radio off. 3. Press the 1 and 4 buttons together. Hold them down

until SEC shows on the display.

4. Press MN and 000 will appear on the display. 5. Press MN again to make the last two digits agree

with your code.

6. Press HR to make the first one or two digits agree

with your code.

7. Press AM-FM after you have confirmed that the

code matches the secret code you have written down. The display will show ---, indicating that the radio is no longer secured.

If the code entered is incorrect, SEC will appear on the display. The radio will remain secured until the correct code is entered. When battery power is removed and later applied to a secured radio, the radio won’t turn on and LOC will appear on the display. To unlock a secured radio, see “Unlocking the Theft-Deterrent Feature After a Power Loss” earlier in this section. Understanding Radio Reception FM Stereo FM stereo will give you 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 come and go. AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it.

3-25

Tips About Your Audio System Hearing damage from loud noise is almost unaerectable until it is too late. Your hearing can adapt to higher volumes of sound. Sound that seems normal can be loud and harmful to your hearing. Take precautions by adjusting the volume control on your radio to a safe sound level before your hearing adapts to it. To help avoid hearing loss or damage:

Adjust the volume control to the lowest setting. Increase volume slowly until you hear comfortably and clearly.

I NOTICE:

Before you add any sound equipment to your vehicle -- like a tape player, CB radio, mobile telephone or two-way radio -- be sure you can add what you want. If you can, it’s very important to do it properly. Added sound equipment may interfere with the operation of your vehicle’s engine, Delco radio or other systems, and even damage them. Your vehicle’s systems may interfere with the operation of sound equipment that has been added improperly. So, before adding sound equipment, check with your dealer and be sure to check Federal rules covering mobile radio and telephone units.

Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes or a damaged mechanism. Cassette tapes should be stored in their cases away from contaminants, direct sunlight and extreme heat. If they aren’t, they may not operate properly or may cause failure of the tape player. Your tape player should be cleaned regularly after every 50 hours of use. Your radio may display CLN to indicate that you have used your tape player for 50 hours without resetting the tape clean timer. If this message appears on the display, your cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to your tapes and player. If you notice a reduction in sound quality, try a known good cassette to see if it is the tape or the tape player at fault. If this other cassette has no improvement in sound quality, clean the tape player. Cleaning may be dc : with a scrubbing action, non-abrasive cleaning cassette with pads which scrub the tape head as the hubs of the cleaner cassette turn. It is normal for the cassette to eject while cleaning. Insert the cassette at least three times to ensure thorough cleaning. A scrubbing action cleaning cassette is available through your GM dealership.

You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassette will not eject and, it may not clean as thoroughly as the scrubbing type cleaner. After you clean the player, press and hold EJECT for five seconds to reset the CLN indicator. The radio will display --- to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before you have your tape player serviced. Care of Your Compact Discs 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 signal surface when handling discs. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge.

Power Antenna Mast Care (If Equipped) Your power anteilfia will look its best and work well if it’s cleaned from time to time. To clean the antenna mast: 1. 2.

Turn on the ignition and radio to raise the antenna. Dampen a clean cloth with mineral spirits or equivalent solvent. Wipe the cloth over the mast sections, removing any dirt. Wipe dry with a clean cloth. Make the antenna go up and down by turning the radio or ignition off and on. Repeat if necessary.

I NOTICE:

Don’t lubricate the power antenna. Lubrication could damage it.

3-28

I NOTICE:

Before entering an automatic car wash, turn off your radio to make the power antenna go down. This will prevent the mast from possibly getting damaged. If the antenna does not go down when you turn the radio off, it may be damaged or need to be cleaned. In either case, lower the antenna by hand by carefully pressing the antenna down.

If the mast portion of your antenna is damaged, you can easily replace it. See your dealer for a replacement kit and follow the instructions in the kit. Adjustable Mast Antenna The mast should be fully retracted before entering any automated wash facility to minimize the risk of antenna damage. If the mast should ever become slightly bent, you can straighten it out by hand. If the mast is badly bent, as it might be by vandals, you should replace it. Check every once in a while to be sure the antenna is still tightened to the body side panel.

Please start with a very important safety device in your vehicle: Buckle up. (See “Safety Belts” in the Index.) 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’s 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 The best advice anyone can give about driving is: Drive defensively.

Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s 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

0 Muscular Coordination

Vision

0 Attentiveness. 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, some 17,000 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 2 1, it’s 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 solve this highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is “too much” if the driver plans to drive? It’s 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: 0 The amount of alcohol consumed 0 The drinker’s body weight 0 The amount of food that is consumed before and

during drinking

0 The length of time it has taken the drinker to

consume the alcohol.

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 a liquor like whiskey, gin or vodka.

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 when each has the same number of drinks. The law in many U.S. states sets the legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limit is 0.08 percent. In some other countries, it’s even lower. 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’ve seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them. 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!

It’s 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.

4-4

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’ll be careful” isn’t the right answer. What if there‘s 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’s something else about drinking and driving that many people don’t 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.

Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness and of alcohol. You can have a serious -- or even judgment can be affected by even a small amount fatal -- collision if you drive after drinking. Please don’t drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you’re 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’re driving on snow or ice, it’s easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. 4-6

Braking Ekaking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That’s perception time. Then you have to bring up your foot and do it. That’s reaction time. Average reaction time is about 314 of a second. But that’s 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’s 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’re driving, brake normally but don’t 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.

Anti-Lock Brakes (ABS) Your vehicle has anti-lock brakes (ABS). 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. This is normal.

If there’s a problem with the anti-lock brake system, this warning light will stay on. See “Anti-Lock Brake System Warning Light” in the Index.

ANTI - LOCK

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.

Here’s how anti-lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here’s 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 front wheel and at the rear wheels.

4-8

You can steer around the obstacle while braking hard. As you brake, your c6mputer keeps receiving updates on wheel speed and controls braking pressure accordingly.

Remember: Anti-lock doesn’t 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 won’t 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 Don’t pump the brakes. Just hold the brake pedal down and let anti-lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal. Braking in Emergencies With anti-lock, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking.

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’s important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here’s 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’s no traction, inertia will keep the vehicle going in the same direction. If you’ve ever tried to steer a vehicle on wet ice, you’ll understand this.

4-9

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’t; there isn’t room. That’s 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 in Emergencies” earlier in this section.) 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.

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’re in a curve, speed is the one factor you can control. Suppose you’re steering through a sharp curve. Then you suddenly accelerate. Both control systems -- steering and acceleration -- have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. What should you do if this ever happens? Ease up on the 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’ll 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.

4-10

Off-Road Recovery You may find sometime 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.

p/y/

edge of paved surface

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:

“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.

0 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’s 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.

Do not get too close to the vehicle you want to pass while you’re awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you’re following a larger vehicle. Also, you won’t have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance.

0 When it looks like a chance to pass is coming up,

start to accelerate but stay in the right lane and don’t 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 cars are lined up to pass a slow vehicle, wait your turn. But take care that someone isn’t trying to pass you as you pull out to pass the slow vehicle. Remember to glance over your shoulder and check the blind spot.

0 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.)

0 Try not to pass more than one vehicle at a time on

two-lane roads. Reconsider before passing the next vehicle. Don’t 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’re 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’s review what driving experts say about what happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the tires meet the road to do what the driver has asked. In any emergency, don’t 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 aren’t 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 and an acceleration skid are 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’ll 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. Remember: Any anti-lock brake system (ABS) helps avoid only the braking skid.

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.

Here are some tips on night driving.

Drive defensively. Don’t drink and drive. Adjust your inside rearview mirror to reduce the glare from headlamps behind you. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles. 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’re tired, pull off the road in a safe place and rest.

Night Vision 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’re driving, don’t 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 readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t 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’s 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 aren’t even aware of it.

Driving in Rain and on Wet Roads

-----A

Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because

your tire-to-road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction. It’s 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. 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’s 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.

Wet brakes can cause accidents. They won't 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.

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 can't, try to slow down before you hit them.

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’re going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road. Hydroplaning doesn’t 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 isn’t a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining.

Driving Through Deep Standing Water

I 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’t avoid deep puddles or standing water, drive through them very slowly.

Some Other Rainy Weather Tips 0 Turn on your low-beam headlamps -- not just

your parking lamps -- to help make you more visible to others. 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.

0 Have good tires with proper tread depth. (See

“Tires” in the Index.)

City Driving

Here are ways to increase your safety in city driving:

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’ll save time and energy. (See the next part, “Freeway Driving.”) 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’ll want to watch out for what the other drivers are doing and pay attention to traffic signals.

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’s 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 isn’t 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. 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’re ready. Try to be well rested. If you must start when you’re not fresh -- such as after a day’s work -- don’t 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’s ready to go. If it needs service, have it done before starting out. Of course, you’ll find experienced and able service experts in

GM dealerships all across North America. They’ll be ready and willing to help if you need it. Here are some things you can check before a trip: Windsh.ield Washer Fluid: Is the reservoir full? Are all windows clean inside and outside? 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? Weuther Forecasts: What’s the weather outlook along your route? Should you delay your trip a short time to avoid a major storm system? Maps: Do you have up-to-date maps?

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. Don’t 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:

Make sure your vehicle is well ventilated, with a comfortably cool interior. 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.

4-22

If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads. 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.

1 A CAUTION:

If you don’t shift down, your brakes could get so hot that they wouldn’t 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.

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 wouldn’t 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.

Know how to go uphill. You may want to shift down to a lower gear. The lower gears help cool your engine and transmission, and you can climb the hill better. Stay in your own lane when driving on two-lane roads in hills or mountains. Don’t swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane. 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. 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.

Winter Dri-ving Here are some tips for winter driving: 0 Have your vehicle in good shape for winter. 0 You may want to put winter emergency supplies in

your vehicle.

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 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’ll have a lot less traction or “grip” and will need to be very careful.

4-24

V ’

What’s 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’s about freezing (32°F; OOC) 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. 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. Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti-lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-Lock” in the Index.

Allow greater following distance on any slippery road. Watch for slippery spots. The road might be fine until you hit a spot that’s covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun can’t 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’re actually on the ice, and avoid sudden steering maneuvers.

If You’re 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: 0 Turn on your hazard flashers.

0 Tie a red cloth to your vehicle to alert police that

you’ve been stopped by the snow. 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.

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’t 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 doesn’t collect there. Open a window just a little on the side of the vehicle that’s away from the wind. This will help keep CO out.

You can run the engine to keep warm, but be careful. 4-26

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 (or batteries) charged. You will need a well-charged battery (or batteries) to restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for awhile. If you have a diesel engine you may have to run it at a higher speed to get enough heat. 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.

Loading Your Vehicle

f i

The CertificatiodTire 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 GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo.

C *.UTION:

Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. 0 Put things in the cargo area of your vehicle.

Try to spread the weight evenly. Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.

0 Don’t leave an unsecured child restraint in

your vehicle. When you carry something inside the vehicle, secure it whenever you can. Don’t leave a seat folded down unless you need to.

The Certificatioflire label also tells you the maximum weights for the front and rear axles, called 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. And, if you do have a heavy load, you should spread
