2003 Chevrolet Suburban Owners Manual

Both frontal and side impact air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, seriously injure you. Safety belts help keep you in position for air bag inflation before and during a crash. Always wear your safety belt, even with frontal air bags. The driver should sit as far back as possible while still maintaining control of the vehicle. Front occupants should not lean on or sleep against the door.

The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See Air Bag Readiness Light on page 3-38 for more information. Where Are the Air Bags?

The driver’s frontal air bag is in the middle of the steering wheel.

Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see the part of this manual called “Older Children” or “Infants and Young Children”.

There is a air bag readiness light on the instrument panel cluster, which shows the air bag symbol.

The right front passernger’s frontal air bag is in the instrument panel on the passenger’s side.

If your vehicle has one, the driver’s side impact air bag is in the side of the driver’s seatback closest to the door.

1-71

If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering. Don’t let seat covers block the inflation path of a side impact air bag.

When Should an Air Bag Inflate? Frontal Air Bags The driver’s and right front passenger’s frontal air bags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact speed is above the system’s designed “threshold level.”

If your vehicle has one, the right front passenger’s side impact air bag is in the side of the passenger’s seatback closest to the door.

1-72

In addition, your vehicle has “dual stage” frontal air bags, which adjust the amount of restraint according to crash severity. For moderate frontal impacts, these air bags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs. If the front of your vehicle goes straight into a wall that doesn’t move or deform, the threshold level for the reduced deployment is about 10 to 16 mph (16 to 25 km/h), and the threshold level for a full deployment is about 20 to 25 mph (32 to 40 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range. If your vehicle strikes something that will move or deform, such as a parked car, the threshold level will be higher. The driver’s and right front passenger’s frontal air bags are not designed to inflate in rollovers, rear impacts, or in many side impacts because inflation would not help the occupant. Seat Position Sensors Vehicle’s with dual stage air bags are also equipped with special sensors which enable the sensing system to monitor the position of both the driver and passenger front seats. The seat position sensor provides information which is used to determine if the air bags should deploy at a reduced level or at full depoyment.

Side Impact Air Bags Your vehicle may or may not have a side impact air bag. See Air Bag Systems on page 1-68. Side impact air bags are designed to inflate in moderate to severe side crashes. A side impact air bag will inflate if the crash severity is above the system’s designed “threshold level.” The threshold level can vary with specific vehicle design. Side impact air bags are not designed to inflate in frontal or near-frontal impacts, rollovers or rear impacts, because inflation would not help the occupant. A side impact air bag will only deploy on the side of the vehicle that is struck. Air Bag Systems In any particular crash, no one can say whether an air bag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. For frontal air bags, inflation is determined by the angle of the impact and how quickly the vehicle slows down in frontal and near-frontal impacts. For side impact air bags, inflation is determined by the location and severity of the impact. The air bag system is designed to work properly under a wide range of conditions, including off-road usage. Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See Off-Road Driving with Your Four-wheel Drive Vehicle in the Index for tips on off-road driving.

1-73

What Makes an Air Bag Inflate? In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. For both frontal and side impact air bags, the sensing system triggers a release of gas from the inflator, which inflates the air bag. The inflator, the air bag and related hardware are all part of the air bag modules. Frontal air bag modules are located inside the steering wheel and instrument panel. For vehicles with side impact air bags, the air bag modules are located in the seatback closest to the driver’s and/or right front passenger’s door. How Does an Air Bag Restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. The air bag supplements the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually. But the frontal air bags would not help you in many types of collisions, including rollovers, rear impacts, and many side impacts, primarily because an occupant’s motion is not toward the air bag. Side impact air bags would not help you in many types of collisions, including frontal or near frontal collisions, rollovers, and rear impacts,

1-74

primarily because an occupant’s motion is not toward those air bags. Air bags should never be regarded as anything more than a supplement to safety belts, and then only in moderate to severe frontal or near-frontal collisions for the driver’s and right front passenger’s frontal air bags, and only in moderate to severe side collisions for vehicle’s with a driver’s and right front passenger’s side impact air bag.

What Will You See After an Air Bag Inflates?

After the air bag inflates, it quickly deflates, so quickly that some people may not even realize the air bag inflated. Some components of the air bag module will be hot for a short time. These components include the steering wheel hub for the driver’s frontal air bag and the instrument panel for the right front passenger’s frontal air bag. For vehicles with side impact air bags, the side of the seatback closest to the driver’s and/or right front passenger’s door will be hot. The parts of the bag that come into contact with you may be warm, but not too hot to touch. There will be some smoke and dust coming from the vents in the deflated air bags. Air bag inflation doesn’t prevent the driver from seeing or being able to steer the vehicle, nor does it stop people from leaving the vehicle.

WIBum~ an air bag inflates, there is dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but can’t get out of the vehicle after an air bag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an air bag deployment, you should seek medical attention.

In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. Air bags are designed to air bag inflates, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts.

Your vehicle is equipped with electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. Your vehicle is also equipped with a crash sensing and diagnostic module, which records information about the frontal air bag system. The module records information about the readiness of the system and when the system commands are bag inflation. It records the status of the driver’s safety belt usage in a crash in which the air bag deploys or a crash in which the air bag nearly deploys. The module also records speed, engine RPM, brake and throttle data.

systems. Improper service can mean that an air bag system won’t work properly. See your dealer for service.

Notice: If you damage the covering for the driver’s or the right front passenger’s air bag, or the air bag covering on the driver’s and right front passenger’s seatback, the bag may not work properly. You may have to replace the air bag module in the steering wheel, both the air bag module and the instrument panel for the right front passenger’s air bag, or both the air bag module and seatback for the driver’s and right front passenger’s side impact air bag. Do not open or break the air bag coverings.

Passenger Sensing System

If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system. The indicator will be visible when you turn your ignition key to START or RUN. The words ON and OFF or the symbol for on and off, will be visible on the rearview mirror during the system check. When the system check is complete, either the word ON or the word OFF, or the symbol for on or the symbol for off will be visible. See Passenger Air Bag Status Indicator on page 3-38. If your rearview mirror doesn’t have either of the indicators pictured below, then your vehicle doesn’t have the passenger sensing system.

Passenger Air Bag Status Indicator - United States

1-76

Passenger Air

Bag Status

Indicator - Canada

The passenger sensing system will turn off the right front passenger’s frontal air bag under certain conditions. The driver’s air bag and the side air bags are not part of the passenger sensing system. The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt. The sensors are designed to detect the presence of a properly-seated occupant and determine if the passenger’s frontal air bag should be enabled (may inflate) or not.

The passenger sensing system is designed to turn off the right front passenger’s frontal air bag if:

the right front passenger seat is unoccupied, the system determines that an infant is present in a rear-facing infant seat, the system determines that a small child is present in a forward-facing child restraint, the system determines that a small child is present in a booster seat, a right front passenger takes hidher weight off of the seat for a period of time. the right front passenger seat is occupied by a smaller person, such as a child who has outgrown child restraints or a very small person, or if there is a critical problem with the air bag system or the passenger sensing system.

When the passenger sensing system has turned off the passenger’s frontal air bag, the off indicator will light and stay lit to remind you that the air bag is off. The passenger sensing system is designed to turn off the passenger’s frontal air bag when a rear facing infant seat, a forward-facing child restraint or a booster seat is detected. If the child restraint has been installed and the on indicator is lit, turn the vehicle off, remove the child restraint from the vehicle and reinstall the restraint following the child restraint manufacturer’s

directions and refer to Securing a Child Restraint in the Right Front Seat Position on page 1-64 of this manual. If after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, secure the child in the child restraint in a rear seat position in the vehicle and check with your dealer. The passenger sensing system is designed to enable (may inflate) the right front passenger’s frontal air bag anytime the system senses that a person of adult size is sitting properly in the right front passenger’s seat. When the passenger sensing system has allowed the air bag to be enabled, the on indicator will light and stay lit to remind you that the air bag is active. If a person of adult-size is sitting in the right front passenger’s seat, but the off indicator is lit, it could be because that person isn’t sitting properly in the seat. If this happens, turn the vehicle off and ask the person to place the seatback in the full upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended. Restart the vehicle and have the person remain in this position for about two minutes. This will allow the system to detect that person and then enable the passenger’s air bag.

1-77

If the air bag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the air bag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the frontal air bag. See “Air Bag Readiness Light” in the Index for more on this, including important safety information.

Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system.

Stowing of articles under the passenger’s seat or between the passenger’s seat cushion and seatback may interfere with the proper operation of the passenger sensing system.

Servicing Your Air Bag-Equipped Vehicle

Adding Equipment to Your Air Bag-Equipped Vehicle

Q: Is there anything I might add to the front or sides of the vehicle that could keep the air bags from working properly? A: Yes. If you add things that change your vehicle’s

frame, bumper system, front end or side sheet metal or height, they may keep the air bag system from working properly. Also, the air bag system may not work properly if you relocate any of the air bag sensors. If you have any questions about this, you should contact Customer Assistance before you modify your vehicle. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See Customer Satisfaction Procedure on page 7-2.

Air bags affect how your vehicle should be serviced. There air bag system parts in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see Service Publications Ordering Information on page 7- 1 1.

For up to 1 minute after the ignition key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates. Avoid yellow connectors. They are probably part of the air bag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

Air bag systems do not need regular maintenance.

Restraint System Check

Checking Your Restraint Systems

Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.

Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Also look for any opened or broken air bag covers, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

1-80

If the LATCH system was being used during a more severe crash, you may need new LATCH system parts. If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt or LATCH system wasn’t being used at the time of the collision. If an air bag inflates, you’ll need to replace air bag system parts. See the part on the air bag system earlier in this section.

Replacing Restraint System Parts After a Crash

A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it,resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

If you’ve had a crash, do you need new belts or LATCH system parts? After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts.

Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.

2-3

Your vehicle has one double-sided key for the ignition and all door locks as well as the spare tire hoist lock, if equipped.

If you ever lose your keys, your dealer will be able to assist you with obtaining replacements. Notice: Your vehicle has a number of features that can help prevent theft. You can have a lot of trouble getting into your vehicle if you ever lock your keys inside. You may even have to damage your vehicle to get in. So be sure you have spare keys.

2-4

If you ever do get locked out of your vehicle, call the GM Roadside Assistance Center. See Roadside Assistance Program on page 7-6. If your vehicle is equipped with the Onstar@ system with an active subscription and you lock your keys inside the vehicle, Onstat-@ may be able to send a command to unlock your vehicle. See OnStaP System on page 2-51 for more information. Remote Keyless Entry System If equipped, the keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause interference, and 2. This device must accept any interference received,

including interference that may cause undesired operation of the device.

This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference, and 2. This device must accept any interference received,

including interference that may cause undesired operation of the device.

Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this:

Check the distance. You may be vehicle. You may need to stand closer during rainy or snowy weather.

Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about two years. You can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery. Notice: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter.

Remote Alarm When the panic button with the horn symbol on the keyless entry transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the panic button again, waiting for 30 seconds, or starting the vehicle. Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it.

2-6

To replace the battery in the keyless entry transmitter do the following:

2. Remove and replace the battery with a three-volt CR2032 or equivalent battery, positive (+) side up.

3. Align the covers and snap them together. 4. Resynchronize the transmitter. 5. Check the operation of the transmitter.

1. Insert a dime, or similar object, in the slot between the covers of the transmitter housing near the key ring hole. Remove the bottom by twisting the dime.

Doors and Locks

Door Locks

/r\ CAUTION:

Unlocked doors can be dangerous.

Passengers - especially children - can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive. Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening.

Liftgate Glass and Liftgate To open a mechanical lock system from the outside, insert the key into the lock and turn it counterclockwise to unlock the glass and liftgate. The liftgate glass can be opened using the button on the liftgate after the doors have been unlocked. This can be done by using either the power door locks or the remote keyless entry system. To open the entire liftgate, lift the handle located in the center of the door. To lock a power lock system from the outside, insert the key into the lock button and turn clockwise. All doors will lock. You may also use the keyless entry system or the power door locks to lock the liftgate and liftgate glass.

Liftgate

It Can be dangerous to drive with tnn, liftgate glass, liftgate or rear doors open because carbon monoxide (CO) gas can come into your vehicle. You can’t see or smell CO. It can cause unconsciousness and even death. If you must drive with the liftgate glass, liftgate or rear doors open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate glass, liftgate or rear doors:

Make sure all other windows are shut. Turn the fan on your heating or cooling system to its highest speed with the setting on VENT or OUTSIDE AIR. That will force outside air into your vehicle. See “Comfort Controls” in the Index.

Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. Content Theft-Deterrent Your vehicle may be equipped with a content theft-deterrent alarm system.

With this system, the security light will flash as you open the door (if your ignition is off), to let you know that you are activating the system.

This message reminds you to activate the theft-deterrent system. Here’s how to do it:

1. 2.

3.

Open the door. Lock the door with the power door lock switch or the remote keyless entry transmitter. The security light should come on and flash. If using the remote keyless entry transmitter, the door does not need to be open. If the delayed locking feature is active, the alarm will not be activated until all doors are closed and the security light goes off. Close all doors. The security light will stop flashing and stay solid. The light should go off after approximately 30 seconds. The alarm is not armed until the security light goes off.

If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power.

2-1 8

Remember, the theft-deterrent system won’t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here’s how to avoid setting off the alarm by accident:

locked with the door

If you don’t want to activate the theft-deterrent system, the vehicle should be key after the doors are closed. Always unlock a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm if the system has been armed.

If you set off the alarm by accident, unlock any door with the key. You can also turn off the alarm by pressing UNLOCK on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START.

Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, lower the driver’s window

and open the driver’s door,

2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter.

3. Get out of the vehicle, close the door and wait for

the security light to go out.

4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

If the alarm does not sound when it should but the vehicle’s headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers on page 5-97. If the alarm does not sound or the vehicle’s headlamps do not flash, the vehicle should be serviced by an authorized service center.

2-1 9

Passlock@ Your vehicle is equipped with the Passlock@ theft-deterrent system. Passlock@ is a passive theft-deterrent system. Passlock@ enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock@ system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock@ at this time. You may also want to check the fuse (see Fuses and Circuit Breakers on page 5-97.) See your dealer for service. In an emergency, call the GM Roadside Assistance Center. See Roadside Assistance Program on page 7-6 under Customer Assistance Information.

Starting and Operating Your Vehicle

New Vehicle Break-in

Notice: Your vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). Don’t drive at any one speed - fast or slow - for the first 500 miles (805 km). Don’t make full-throttle starts. Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. Don’t tow a trailer during break-in. See “Towing a Trailer” in the Index for more information.

Ignition Positions

With the key in the ignition switch, you can turn the key to four different positions.

A (LOCK): This position locks your ignition and transmission. It’s a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK.

B (ACCESSORY): This position lets you use things like the radio, power windows and the windshield wipers when the engine is off.

2-2 1

Notice: If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of these works, then your vehicle needs service. C (RUN): This is the position for driving. D (START): This position starts your engine. Retained Accessory Power (RAP) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 10 minutes after the ignition key is turned to OFF. Your radio, power windows, sunroof (if equipped), and Onstar@ System (if equipped) will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to LOCK, these features will continue to work for up to 10 minutes or until a door is opened.

Starting Your Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position - that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only. Notice: Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped.

1. With your foot off the accelerator pedal, turn the

ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.

Notice: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter. 2. If it doesn’t start within 10 seconds, push the

accelerator pedal all the way to the floor, while you hold the ignition key in START. When the engine starts, let go of the key and let up on the accelerator pedal. Wait about 15 seconds between each try.

2-22

When starting your engine in very cold weather (below 0°F or -18"C), do this: 1. With your foot off the accelerator pedal, turn the

ignition key to START and hold it there up to 75 seconds. When the engine starts, let go of the key.

2. If your engine still won't start (or starts but then

stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing, but this time keep the pedal down for five or six seconds. This clears the extra gasoline from the engine.

Notice: Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you don't, your engine might not perform properly.

Adjustable Throttle and Brake Pedal

If your vehicle is equipped with this feature, you can change the position of the throttle and brake pedals. This feature is designed for shorter drivers, since the pedals can not move farther away from the standard position, but can move forward for better pedal reach. The vehicle must be in PARK (P) for this feature to operate.

The switch used to adjust the pedals is located on the driver's side door panel.

Press the arrow at the end of the switch closest to you to move the pedals closer to your body. Press the arrow at the far end of the switch to move the pedals away from your body.

Engine Coolant Heater

3. Plug it into a normal, grounded 1 IO-volt AC outlet.

In very cold weather, 0°F (-18°C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.

the cord into an una. wnded outlet

PIL,,--lg could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord won’t reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

At temperatures above 32°F (OOC), use of the coolant heater is not required. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The

cord is located on the driver’s side of the engine compartment, near the power steering fluid reservoir. If you have a diesel engine, refer to diesel supplement for location.

4. Before starting the engine, be sure to unplug and

store the cord as it was before to keep it away from moving engine parts. If you don’t, it could be damaged.

How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you’ll be parking your vehicle. The dealer can give you the best advice for that particular area.

2-24

Automatic Transmission Operation There are several different positions for your shift lever. Your vehicle is equipped with an automatic transmission and features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P).

PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.

lers cl---- De injure

- J su enly. be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See “Shifting Into Park (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move

CAUTION:

(Continued)

If you have four- wheel drive, your vehicle will be free to roll - even if your shift lever is in PARK (P) - if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear, two-wheel high (2H) or four- wheel high (4H) or four-wheel low (4L) - not in NEUTRAL. See ”Shifting into Park (P)” in the index.

2-25

REVERSE (R): Use this gear to back up.

Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage your transmission. Shift to REVERSE (R) only after your vehicle is stopped. To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see If You Are Stuck: In Sand, Mud, Ice or Snow on page 4-50.

NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your two-wheel drive vehicle is being towed.

Sh-- --ng into a d.. . e gear w ... Je your engine is “racing” (running at high speed) is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Don’t shift into a drive gear while your engine is racing.

!-26

Notice: Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty.

DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re:

Going less than about 35 mph (56 km/h), push your accelerator pedal about halfway down. Going about 35 mph (56 km/h) or more, push the accelerator all the way down.

You’ll shift down to the next gear and have more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often.

THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D).

SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on.

If you manually select SECOND (2) in a light duty automatic transmission, the transmission will drive in second gear. You may use this feature for reducing the speed of the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces.

FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough. Notice: If your rear wheels won’t turn, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill. On cold days, approximately 32°F (0°C) or colder, your transmission is designed to shift differently until the engine reaches normal operating temperature. This is intended to improve heater performance.

Tow/HauI Mode

Your vehicle may be equipped with a tow/haul mode. If so, the selector button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. See Towing a Trailer on page 4-59 for more information.

When tow/haul mode is selected the tow/haul indicator light will illuminate.

The tow/haul mode also interacts with the AutorideTM feature, if your vehicle is so equipped, to enhance the ride when trailering or with a loaded vehicle. See AutorideTM on page 4-58. Four-wheel Drive

If your vehicle has four-wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle.

Notice: Driving in the 4-WHEEL HIGH (4HI) or 4-WHEEL LOW (4LO) positions for a long time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.

2-28

Automatic Transfer Case

The transfer case buttons are located to the left of the instrument pane! cluster.

Use these switches to shift into and out of four-wheel drive. You can choose among four driving settings:

a (2HI): This setting is used for driving in most street

and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy.

AUTO 4WD: This setting is ideal for use when road conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent only to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four-wheel drive. Driving in this mode results in slightly lower fuel economy than 2HI.

(4HI): Use the 4HI position when you need extra

traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow.

(4LO): This setting also engages your front axle

and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels. You might choose 4LO if you are driving off-road in deep sand, deep mud, deep snow and climbing or descending steep hills.

2-29

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See ”Parking Brake” in the Index.

NEUTRAL: Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-53 or Towing Your Vehicle on page 4-53 for more information. Indicator lights in the switches show which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while shifting the transfer case. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting.

Shifting into 4HI or AUTO 4WD Press and release the 4 hi or AUTO 4WD switch. This can be done at any speed (except when shifting from 4LO), and the indicator light will flash while shifting. It will remain illuminated when the shift is completed. Shifting into 2HI Press and release the 2 hi switch. This can be done at any speed (except when shifting from 4LO). Shifting into 4LO To shift to the 4 lo position, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4 lo switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission in gear. If the 4 lo switch is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). After 30 seconds the transfer case will return to the setting last chosen.

Shifting Out of 4LO To shift from 4LO to 4HI, AUTO 4WD or 2HI your vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of 4LO is to have your vehicle moving 1 to 2 rnph (1.6 to 3.2 km/h). Press and release the 4HI, AUTO 4WD or 2HI switch. You must wait for the 4HI, AUTO 4WD or 2HI indicator light to stop flashing and remain illuminated before shifting your transmission into gear. If the 4HI, AUTO 4WD or 2HI switch is pressed when your vehicle is in gear and/or moving, the 4HI, AUTO 4WD or 2HI indicator light will flash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N).

Shifting into NEUTRAL To shift the transfer case to NEUTRAL do the following:

1. Make sure the vehicle is parked so that it will

not roil

4. Turn the ignition key to LOCK. 5. Remove the key and take it with you. If you can leave your vehicle with the ignition key in your hand, your vehicle is in PARK (P).

Then, see if you can move the shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn’t fully locked into PARK (P). Torque Lock If you are parking on a hill and you don’t shift your transmission into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of PARK (P). This is called ”torque lock.” To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver’s seat. To find out how, see Shifting lnto Park (P) on page 2-36. When you are ready to drive, move the shift lever out of PARK (P) before you release the parking brake. If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission, so you can pull the shift lever out of PARK (P).

Shifting Out of Park (P) Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is in RUN. See Automatic Transmission Operation on page 2-25. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want. If you ever hold the brake pedal down but still can’t shift out of PARK (P), try this: 1. Turn the key to LOCK. 2. Apply and hold the brake until the end of Step 4. 3. Shift the vehicle to NEUTRAL (N). 4. Start the vehicle and then shift to the drive gear

you want.

5. Have the system fixed as soon as you can.

Exhaust

Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can’t see or smell. It can cause unconsciousness and death. You might have exhaust coming in if:

Your exhaust system sounds strange or different. Your vehicle gets rusty underneath. Your vehicle was damaged in a collision. Your vehicle was damaged when driving over high points on the road or over road debris. Repairs weren’t done correctly. Your vehicle or exhaust system had been modified improperly.

If you ever suspect exhaust is coming into your vehicle:

Drive it only with all the windows down to blow out any CO; and Have your vehicle fixed immediately.

Running Your Engine While You Are Parked

It’s better not to park with the engine running. But if you ever have to ‘?ere are some thi7gs to know

Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier Caution under ”Engine Exhaust.” Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the fan is at the highest setting. One place this can happen is a garage. Exhaust - with CO - can come in easily. NEVER park in a garage with the engine running. Another closed-in place can be a blizzard. See “Winter Driving” in the Index.

It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you’ve left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).

case in NEUTRAL will allow the vehicle to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear - not in NEUTRAL. Always set your parking brake.

Follow the proper steps to be sure your vehicle won’t move. See Shifting Into Park (P) on page 2-36. If you’re pulling a trailer, see Towing a Trailer on page 4-59.

Electrochromic Mirror Operation The electrochromic (self dimming) mirror function is turned on automatically each time the ignition is started. Po operate the electrochromic mirror do the following: 1. Make sure the green indicator light, located to

the left of the on/off button, is lit. If it’s not, press and hold the on/off button for approximately six seconds until the green light comes on, indicating that the mirror is in electrochromic (self dimming) mode.

2. Turn off the electrochromic mirror function by

pressing and holding the on/off button for approximately six seconds until the green indicator light turns off.

Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings.

To adjust for compass variance do the following: 1. Find your current location and variance zone

number on the following zone map.

2. Press and hold the on/off button until a Z and a

zone number appears in the display. The compass is now in zone mode.
