children always should be secured in appropriate child restraints. For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs. {CAUTION: Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’s neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear-facing seat settles into the restraint, so the crash forces can be distributed across the strongest part of an infant’s body, the back and shoulders. Infants always should be secured in appropriate infant restraints. 1-43 Child Restraint Systems An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous ﬂat surface. Make sure that the infant’s head rests toward the center of the vehicle. A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. 1-44 A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. A booster seat (F-G) is a child restraint designed to improve the ﬁt of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a ﬁve-point harness. A booster seat can also help a child to see out the window. 1-45 When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards. Then follow the instructions for the restraint. You may ﬁnd these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system or the LATCH system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury. When securing an add-on child restraint, refer to the instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this manual. The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer. Q: How do child restraints work? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint. The vehicle’s belt system secures the add-on child restraint in the vehicle, and the add-on child restraint’s harness system holds the child in place within the restraint. One system, the three-point harness, has straps that come down over each of the infant’s shoulders and buckle together at the crotch. The ﬁve-point harness system has two shoulder straps, two hip straps and a crotch strap. A shield may take the place of hip straps. A T-shaped shield has shoulder straps that are attached to a ﬂat pad which rests low against the child’s body. A shelf- or armrest-type shield has straps that are attached to a wide, shelf-like shield that swings up or to the side. 1-46 Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We, therefore, recommend that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. If you need to secure a child restraint in the right front passenger’s seat, there is a switch on the instrument panel that you can use to turn off the passenger’s air bag. See Air Bag Off Switch on page 1-68 and Securing a Child Restraint in the Right Front Seat Position on page 1-55, for more on this including important safety information. Never put a rear-facing child restraint in the right front passenger seat unless the air bag is off. Here is why: {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. Even though the air bag off switch is designed to turn off the passenger’s air bag, no system is fail safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though it is turned off. General Motors recommends that rear-facing child restraints be secured in the rear seat, even if the air bag is off. If you secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. 1-47 Wherever you install it, be sure to secure the child restraint properly. Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in your vehicle — even when no child is in it. Top Strap Some child restraints have a top strap, or “top tether.” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. Some top strap-equipped child restraints are designed for use with or without the top strap being anchored. Others require the top strap always to be anchored. Be sure to read and follow the instructions for your child restraint. If yours requires that the top strap be anchored, don’t use the restraint unless it is anchored properly. If the child restraint does not have a top strap, one can be obtained, in kit form, for many child restraints. Ask the child restraint manufacturer whether or not a kit is available. 1-48 In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. Raise the head restraint and route the top strap under it. Top Strap Anchor Location A child restraint with a top strap should only be used in the second or third row. Don’t use a child restraint with a top strap in the front seat because there’s no place to anchor the top strap. An anchor loop bracket for a top strap is located at the bottom rear of the seat cushion for each seating position in the second row and in the outboard passenger position in the third row. {CAUTION: Each top tether bracket is designed to anchor only one child restraint. Attaching more than one child restraint to a single bracket could cause the anchor to come loose or even break during a crash. A child or others could be injured if this happens. To help prevent injury to people and damage to your vehicle, attach only one child restraint per bracket. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say. Second Row Seats 1-49 Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle has the LATCH system. You will ﬁnd anchors (A) in the center and right side passenger second row seating positions. This system, designed to make installation of child restraints easier, does not use the vehicle’s safety belts. Instead, it uses vehicle anchors (A, B) and child restraint attachements to secure the restraints. Some restraints also use another vehicle anchor to secure a top tether strap (C). Third Row Seat 1-50 In order to use the LATCH system in your vehicle, you need a child restraint designed for that system. 1-51 To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a visible metal anchorage point in the seat where the seatback meets the seat cushion. {CAUTION: If a LATCH-type child restraint is not attached to its anchorage points, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual. Securing a Child Restraint Designed for the LATCH System 1. Find the LATCH anchorages for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion. See Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-50. 2. Put the child restraint on the seat. 3. Attach and tighten the LATCH attachments on the child restraint to the LATCH anchorages in the vehicle. The child restraint instructions will show you how. 4. If the child restraint is forward-facing, attach and tighten the top tether to the top tether anchorage. The child restraint instructions will show you how. Also see Top Strap on page 1-48. 5. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, simply unhook the top tether from the top tether anchorage and then disconnect the LATCH attachments from the LATCH anchorages. 1-52 Securing a Child Restraint in a Rear Seat Position If your child restraint does not have the LATCH system, you will be using the lap-shoulder belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1. Put the restraint on the seat. 2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. If your child restraint is equipped with the LATCH system, see Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-50. See Top Strap on page 1-48 if the child restraint has one. 1-53 3. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 1-54 To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. Securing a Child Restraint in the Right Front Seat Position 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you are using a forward-facing child restraint, you may ﬁnd it helpful to use your knee to push down on the child restraint as you tighten the belt. 6. Push and pull the child restraint in different directions to be sure it is secure. 1-55 If your child restraint is equipped with the LATCH system, see Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-50. See Top Strap on page 1-48 if your child restraint has one. Your vehicle has a right front passenger air bag. There is a switch on the instrument panel that you can use to turn off the right front passenger’s air bag when you need to secure a child restraint at the right front passenger’s position. See Air Bag Off Switch on page 1-68 for more on this, including important safety information. 1-56 United States {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. Even though the air bag off switch is designed to turn off the passenger’s air bag, no system is fail safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though it is turned off. General Motors recommends that rear-facing child restraints be secured in the rear seat, even if the air bag is off. If you secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. 1-57 Canada A rear seat is a safer place to secure a forward-facing child restraint. Never put a rear-facing child restraint in the right front passenger’s seat unless the air bag is off. Here is why: {CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inﬂate even though the switch is off. If this ever happens, don’t let anyone whom the national government has identiﬁed as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in the right front seat ) until you have your vehicle serviced. See “Air Bag Off Switch.” You will be using a lap-shoulder belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1. Your vehicle has a right front passenger’s air bag. See Air Bag Off Switch on page 1-68. If your child restraint is forward-facing, move the seat as far back as it will go before securing the restraint in this seat. See “Seats” in the Index. If you need to use a rear-facing child restraint in this seat, make sure the air bag is off once the child restraint has been installed. 2. Put the child restraint on the seat. 3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 1-58 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 1-59 To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. If you had turned the air bag off with the switch, remember to be sure to use the air bag off switch to turn on the right front passenger’s air bag when you remove the child restraint from the vehicle unless the person who will be sitting there is a member of the passenger air bag risk group. See Air Bag Off Switch on page 1-68. {CAUTION: If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identiﬁed by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inﬂate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See ″Air Bag Off Switch″ in the Index for more on this, including important safety information. 6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you are using a forward-facing child restraint, you may ﬁnd it helpful to use your knee to push down on the child restraint as you tighten the belt. 7. Push and pull the child restraint in different directions to be sure it is secure. 1-60 Air Bag System This part explains the air bag system. Your vehicle has air bags – one air bag for the driver and another air bag for the right front passenger. Frontal air bags are designed to help reduce the risk of injury from the force of an inﬂating air bag. But these air bags must inﬂate very quickly to do their job and comply with federal regulations. Here are the most important things to know about the air bag system: {CAUTION: You can be severely injured or killed in a crash if you are not wearing your safety belt — even if you have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Air bags are designed to work with safety belts, but do not replace them. Airbags are designed to deploy only in moderate to severe frontal and near frontal crashes. They are not designed to inﬂate in rollover, rear or low-speed frontal crashes, or in many side crashes. And, for some unrestrained occupants, air bags may provide less protection in frontal crashes than more forceful air bags have provided in the past. Everyone in your vehicle should wear a safety belt properly — whether or not there is an air bag for that person. 1-61 {CAUTION: {CAUTION: 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, it could seriously injure you. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with air bags. The driver should sit as far back as possible while still maintaining control of the vehicle. 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, butnot 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 Older Children on page 1-38 and Infants and Young Children on page 1-40. 1-62 There is a air bag readiness light on the instrument panel, which shows the air bag symbol. Where Are the Air Bags? 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 3-28 for more information. The driver’s air bag is in the middle of the steering wheel. 1-63 {CAUTION: 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. The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-64 When Should an Air Bag Inﬂate? An air bag is designed to inﬂate in a moderate to severe frontal, or near-frontal crash. The air bag will inﬂate only if the impact speed is above the system’s designed 'threshold level'. If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about 9 to 17 mph (14 to 27 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 air bag is not designed to inﬂate in rollovers, rear impacts, or in many side impacts because inﬂation would not help the occupant. 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. Inﬂation is determined by the angle of the impact and how quickly the vehicle slows down in frontal or near-frontal impacts. 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 on page 4-17 for more tips on off-road driving. 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. The sensing system triggers a release of gas from the inﬂator, which inﬂates the air bag. The inﬂator, air bag, and related hardware are all part of the air bag modules inside the steering wheel and in the instrument panel in front of the right front passenger. 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. Air bags supplement 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 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 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. 1-65 What Will You See After an Air Bag Inﬂates? After an 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 – the steering wheel hub for the driver’s air bag, or the instrument panel for the right front passenger’s bag – will be hot for a short time. 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. {CAUTION: When 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. 1-66 Your vehicle has a feature that will automatically unlock the doors and turn the interior lamps on when the air bags inﬂate (if battery power is available). You can lock the doors again and turn the interior lamps off by using the door lock and interior lamp controls. In many crashes severe enough to inﬂate the air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. (cid:127) Air bags are designed to inﬂate only once. After they inﬂate, 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. (cid:127) Your vehicle is equipped with a crash sensing and diagnostic module, which records information about the air bag system. The module records information about the readiness of the system, when the system commands air bag inﬂation and driver’s safety belt usage at deployment. The module also records speed, engine rpm, brake and throttle data. Let only qualiﬁed technicians work on your air bag system. Improper service can mean that an air bag system won’t work properly. See your dealer for service. If you damage the covering for the driver’s Notice: or the right front passenger’s air bag, the bag may not work properly. You may have to replace the air bag module in the steering wheel or both the air bag module and the instrument panel for the right front passenger’s air bag. Do not open or break the air bag coverings. 1-67 (cid:127) Air Bag Off Switch Your vehicle has a switch on the instrument panel that you can use to turn off the right front passenger’s air bag. Canada United States 1-68 This switch should only be turned to the off position if the person in the right front passenger’s position is a member of a passenger risk group identiﬁed by the national government as follows: Infant.An infant (less than 1 year old) must ride in the front seat because: (cid:127) my vehicle has no rear seat; (cid:127) my vehicle has a rear seat too small to accommodate a rear-facing infant seat; or the infant has a medical condition which, according to the infant’s physician, makes it necessary for the infant to ride in the front seat so that the driver can constantly monitor the child’s condition. Child age 1 to 12.A child age 1 to 12 must ride in the front seat because: (cid:127) my vehicle has no rear seat; although children ages 1 to 12 ride in the rear seat(s) whenever possible, children ages 1 to 12 sometimes must ride in the front because no space is available in the rear seat(s) of my vehicle; or the child has a medical condition which, according to the child’s physician, makes it necessary for the child to ride in the front seat so that the driver can constantly monitor the child’s condition. Medical Condition.A passenger has a medical condition which, according to his or her physician: causes the passenger air bag to pose a special risk for the passenger; and (cid:127) makes the potential harm from the passenger air bag in a crash greater than the potential harm from turning off the air bag and allowing the passenger, even if belted, to hit the dashboard or windshield in a crash. {CAUTION: If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identiﬁed by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inﬂate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. 1-69 (cid:127) (cid:127) (cid:127) (cid:127) United States Canada To turn off the right front passenger’s air bag, insert your ignition key into the switch, push in, and move the switch to the off position. The air bag off light will come on to let you know that the right front passenger’s air bag is off. The right front passenger’s air bag will remain off until you turn it back on again, and the air bag off light will stay on to remind you that the air bag is off. 1-70 {CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inﬂate even though the switch is off. If this ever happens, don’t let anyone whom the national government has identiﬁed as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in the right front seat) until you have your vehicle serviced. United States 1-71 Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system 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 7-11. {CAUTION: For up to 2 minutes 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 wires, wires wrapped with yellow tape or 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. The air bag system does not need regular maintenance. Canada To turn the right front passenger’s air bag on again, insert your ignition key into the switch, push in, and move the switch to the on position. 1-72 Adding Equipment to Your Air Bag-Equipped Vehicle Q: Is there anything I might add to the front 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 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 on page 7-2. 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.) 1-73 Replacing Restraint System Parts After a Crash {CAUTION: 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. 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. 1-74 Section 2 Features and Controls Keys ...............................................................2-2 Remote Keyless Entry System .........................2-3 Remote Keyless Entry System Operation ...........2-4 Doors and Locks .............................................2-7 Door Locks ....................................................2-7 Power Door Locks ..........................................2-8 Delayed Locking .............................................2-9 Programmable Automatic Door Locks ................2-9 Rear Door Security Locks ..............................2-11 Lockout Protection ........................................2-12 Liftgate ........................................................2-13 Windows ........................................................2-14 Power Windows ............................................2-15 Sun Visors ...................................................2-16 Theft-Deterrent Systems ..................................2-16 Content Theft-Deterrent .................................2-16 Passlock® ....................................................2-18 Starting and Operating Your Vehicle ................2-18 New Vehicle Break-In ....................................2-18 Ignition Positions ..........................................2-19 Starting Your Engine .....................................2-20 Engine Coolant Heater ..................................2-21 Automatic Transmission Operation ...................2-22 All-Wheel Drive ............................................2-25 Parking Brake ..............................................2-29 Shifting Into Park (P) .....................................2-30 Shifting Out of Park (P) .................................2-32 Parking Over Things That Burn .......................2-32 Engine Exhaust ............................................2-33 Running Your Engine While You Are Parked ....2-33 Mirrors ...........................................................2-34 Automatic Dimming Rearview Mirror with Compass and Temperature Display ..............2-34 Outside Power Mirrors ...................................2-37 Outside Convex Mirror ...................................2-38 Outside Heated Mirrors ..................................2-39 Outside Automatic Dimming Mirror with Curb View Assist ..............................................2-39 OnStar® System .............................................2-40 HomeLink® Transmitter ...................................2-42 Programming the HomeLink® Transmitter .........2-42 Storage Areas ................................................2-45 Glove Box ...................................................2-45 Center Overhead Console ..............................2-46 Center Console Storage Area .........................2-46 Luggage Carrier ...........................................2-46 Rear Seat Armrest ........................................2-49 Sunroof .........................................................2-50 Vehicle Personalization ...................................2-51 Memory Seat ...............................................2-51 2-1 Keys {CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons.

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. 2-3 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: (cid:127) Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather. (cid:127) Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again. (cid:127) Check to determine if battery replacement is necessary. See “Battery Replacement” under Remote Keyless Entry System Operation on page 2-4. If you are still having trouble, see your dealer or a qualiﬁed technician for service. Remote Keyless Entry System Operation You can lock and unlock your doors from about 3 feet (1 m) up to 100 feet (30 m) away using the remote keyless entry transmitter supplied with your vehicle. K (Unlock): Press this button once to unlock the driver’s door. The interior lamps will come on. Pressing unlock again within three seconds will cause the remaining doors to unlock. You can choose different feedback options for each press of the unlock button. See DIC Operation and Displays on page 3-44 for more information. 2-4 (cid:127) 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. Q (Lock): Press this button once to lock all of the doors. Pressing lock again within three seconds may cause the horn to chirp for lock conﬁrmation. You can choose different feedback options for each press of the lock button. See DIC Operation and Displays on page 3-44 for more information. L (Panic): Press this button to sound the horn and ﬂash the headlamps and taillamps for up to 30 seconds. Panic can be turned off by pressing the button again, by waiting for 30 seconds, or by 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. 2-5 3. Align the covers and snap them together. 4. Resynchronize the transmitter. See “Resynchronization” next. 5. Check the operation of the transmitter. Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. To resynchronize your transmitter, stand close to your vehicle and press and hold the lock and unlock buttons on the transmitter at the same time for 15 seconds. The door locks should cycle to conﬁrm synchronization. If the locks do not cycle, see your dealer for service. To replace the battery in the keyless entry transmitter, do the following: 1. Insert a thin object, such as a coin, in the slot between the covers of the transmitter housing near the key ring hole. Remove the bottom by twisting the coin. 2. Remove and replace the battery with a three-volt CR2032 or equivalent battery, positive (+) side up. 2-6 Doors and Locks Door Locks {CAUTION: There are several ways to lock and unlock your vehicle. To unlock the door from the outside, use the keyless entry system or the key. To unlock or lock the door from the inside, slide the manual lever forward or rearward. Unlocked doors can be dangerous. (cid:127) Passengers — especially children — can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. You increase the chance of being thrown out of the vehicle in a crash if the doors are not locked. So, wear safety belts properly and lock the doors whenever you drive. (cid:127) 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. (cid:127) 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. 2-7 Power Door Locks Cargo Area Door Lock Switch The power door lock switches are located on the driver’s and front passenger’s armrests. Your vehicle may have a power lock switch in the cargo area on the passenger side of the liftgate opening trim. This switch operates identically to the power door lock switches on the driver’s and front passenger’s armrests. Q (Lock): Remove the ignition key and press the lock symbol to lock all of the doors. If the delayed locking feature is on, the doors will not lock until ﬁve seconds after the last door is closed.

You can exit the program mode any time by turning the ignition to RUN (the doors will automatically lock and unlock and the horn will chirp twice to indicate that you are leaving the program mode). If the lock/unlock switches are not pressed while in the programming mode, the current automatic settings will not be modiﬁed. Rear Door Security Locks With this feature, you can lock the rear doors so they can’t be opened from the inside by passengers. This feature is located on the inside edge of the rear doors. 2-11 To use one of the locks, do the following: 1. Open one of the rear doors. 2. Turn the lock counterclockwise with your ignition key to engage the rear door security lock. The rear doors or your vehicle cannot be opened from the inside when this feature is in use. If you want to open the rear door while the security lock is engaged, unlock the door and open the door from the outside. To disengage the child security lock feature, turn the lock clockwise with your ignition key. Lockout Protection This feature protects you from locking your key in the vehicle when the key is in the ignition and a door is open. If the power lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver’s door will unlock. 3. Close the door. 4. Do the same thing to the other rear door. 2-12 Liftgate {CAUTION: It can be dangerous to drive with the liftgate open because carbon monoxide (CO) gas can come into your vehicle. You can not see or smell CO. It can cause unconsciousness and even death. If you must drive with the liftgate open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate: (cid:127) Make sure all other windows are shut. (cid:127) Turn the fan on your heating or cooling system to its highest speed and select the control setting that will force outside air into your vehicle. See Automatic Climate Control System on page 3-19. If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust on page 2-33. To unlock the liftgate, press the unlock button on any of the power door lock switches or the remote keyless entry transmitter. Open the liftgate by pulling the handle located in the center of the door. To lock the liftgate, press the lock button on any of the power door lock switches or the remote keyless entry transmitter. 2-13 (cid:127) Windows {CAUTION: Leaving children, helpless adults, or pets in a vehicle with the windows closed is dangerous. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke. Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather. 2-14 Power Windows The controls for the power windows are located on the armrest on each of the side doors. The switches operate the windows when the ignition is in RUN, ACCESSORY or when Retained Accessory Power (RAP) is active. See “Retained Accessory Power” under Ignition Positions on page 2-19. The driver’s door also has a switch for each of the passenger’s windows. Press the top of the switch to lower the window. Pull up the top of the switch to raise the window. Express-Down Windows The driver’s and front passenger’s window switches have an express-down feature that allows you to lower the window without continuously pressing the switch. Press the top of the window switch down fully to activate the feature. Lightly tap the switch to open the window slightly. The express-down feature can be interrupted at any time by pulling up on the top of the switch. Lockout Switch Press the lockout switch to prevent passengers from operating the power windows from their switches. A light in the lockout switch will come on to show that the switch has been activated. Press the lockout switch again to return to normal operation. 2-15 Sun Visors To block out glare, you can swing down the visors. You can also swing them out to help block glare at the front and side windows. Illuminated Visor Vanity Mirrors Pull the sunvisor down and lift the mirror cover to turn on the lamps. 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. Content Theft-Deterrent Your vehicle is equipped with a content theft-deterrent alarm system. With this system, the security light in the instrument panel cluster will ﬂash as you open the door if your ignition is off. This light reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or the remote keyless entry transmitter. The security light should come on and stay on. 3. Close all doors. The security light should go off after about 30 seconds. The alarm is not armed until the security light goes off. If a locked door is opened without the key or the remote keyless entry transmitter, the alarm will go off. The headlamps and parking lamps will ﬂash for two minutes, and the horn will sound for 30 seconds, then will turn off to save the battery power. You can choose different feedback options for the alarm. See Driver Information Center (DIC) on page 3-44. 2-16 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: If you don’t want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. (cid:127) 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 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. The alarm won’t stop if you try to unlock a door any other way. 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. While the alarm is set, the power door unlock switch is not operational. If the alarm does not sound when it should but the 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 5-102. If the alarm does not sound or the headlamps do not ﬂash, the vehicle should be serviced by your dealer. 2-17 (cid:127) 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, the fuel system is disabled and the vehicle will not start. During normal operation, the security light will turn off approximately ﬁve seconds after the key is turned to RUN. If the engine stalls and the security light ﬂashes, wait about 10 minutes 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 does not start after three tries, the vehicle needs service. 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 5-102. See your dealer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program on page 7-5. 2-18 Starting and Operating Your Vehicle New Vehicle Break-In Notice: Your vehicle does not need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines: (cid:127) Keep your speed at 55 mph (88 km/h) or less for the ﬁrst 500 miles (805 km). (cid:127) Do not drive at any one speed — fast or slow — for the ﬁrst 500 miles (805 km). Do not make full-throttle starts. (cid:127) Avoid making hard stops for the ﬁrst 200 miles (322 km) or so. During this time your new brake linings are not 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. (cid:127) Do not tow a trailer during break-in. See Towing a Trailer on page 4-75 for more information. Ignition Positions With your key in the ignition switch you can turn it 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. If your key seems stuck in LOCK and you Notice: can not 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. B (ACCESSORY): This position allows you to use things like the radio, power windows and the windshield wipers when the engine is off. C (RUN): This position is for driving. D (START): This position starts your engine. Retained Accessory Power (RAP) The Retained Accessory Power (RAP) feature will allow certain features on your vehicle to continue to work for up to 10 minutes after the ignition key is turned to LOCK. 2-19 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 15 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 do not, your engine might not perform properly. 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: Do not 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. 2-20 Engine Coolant Heater Your vehicle may be equipped with an engine coolant heater. 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. At temperatures above 32°F (0°C), use of the coolant heater is not required. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Locate the electrical cord near the front recovery loop on the driver’s side of the vehicle. 3. Plug it into a normal, grounded 110-volt AC outlet. {CAUTION: Plugging the cord into an ungrounded outlet 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 will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 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. 2-21 Automatic Transmission Operation Your vehicle is equipped with an automatic transmission and features an electronic shift position indicator located within the instrument panel cluster. There are several different positions for your shift lever. PARK (P): This position locks your drive wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. {CAUTION: 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. Do not 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) CAUTION: (Continued) suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See Shifting Into Park (P) on page 2-30. If you are pulling a trailer, see Towing a Trailer on page 4-75. {CAUTION: 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 — not in NEUTRAL. See Shifting Into Park (P) on page 2-30. 2-22 REVERSE (R): Use this gear to back up. Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. 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 4-56. NEUTRAL (N): In this position, your engine doesn’t connect with the drive wheels. To restart when you’re already moving, use NEUTRAL (N) only. {CAUTION: Shifting into a drive gear while your engine is 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. Do not shift into a drive gear while your engine is running at high speed. Notice: Shifting out of PARK (P) or NEUTRAL (N) with the engine running at high speed may damage the transmission. The repairs would not be covered by your warranty. Be sure the engine is not running at high speed when shifting your vehicle. 2-23 DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: (cid:127) Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. (cid:127) Going about 35 mph (55 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), 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. Once the vehicle is moving, shift into DRIVE (D). 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: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. 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. 2-24 Tow/Haul Mode Transfer Case Buttons Your vehicle is equipped with a tow/haul mode. The button is located on the instrument panel to the right of the steering wheel. The transfer case buttons are located to the right of the instrument panel cluster. Use these switches to shift into and out of the different all-wheel drive modes. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” under Towing a Trailer on page 4-75 for more information. All-Wheel Drive All-wheel drive sends your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of all-wheel drive, you must be familiar with its operation. Notice: Driving on pavement in 4HI Lock or 4LO Lock for extended periods may cause premature wear on your vehicle’s powertrain and tires. Do not drive in 4HI Lock or 4LO Lock on pavement for extended periods. You can choose between four modes: G (4HI): This setting is used for driving in most street and highway situations. You can also use this setting for light or variable off-road conditions. H (4HI Lock): Use this mode when you need extra traction in most off-road situations such as sand, mud, snow or level, rocky trails. 2-25 N (NEUTRAL): Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-65 or Towing Your Vehicle on page 4-65 for more information. Indicator lights in the buttons show which mode 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. If the SERVICE 4WD message stays on, you should take your vehicle to your dealer for service. See “Service 4WD message” under Driver Information Center (DIC) on page 3-44. I(4LO Lock): This mode delivers extra torque to all four wheels and is used for extreme off-road conditions. You might choose 4LO Lock if you are driving off-road, deep sand, mud, or snow and climbing or descending steep hills. When in this mode you can also choose to lock the rear axle for additional traction in extreme off-road situations. See Locking Rear Axle on page 4-11. Notice: Operating your vehicle in 4LO Lock above 50 mph (80 km/h) for any extended period of time could cause damage to the transfer case. Do not operate your vehicle in 4LO Lock above 50 mph (80 km/h) for extended periods. {CAUTION: 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 on page 2-29. 2-26 Shifting into 4HI or 4HI Lock With the vehicle traveling less than 40 mph (64 km/h), press and release the 4HI or 4HI Lock button. The indicator light will ﬂash while shifting. It will remain illuminated when the shift is complete. It may be necessary to drive backwards for a short distance of 25 feet (7.5 m) to get the lock feature to disengage. Shifting into 4LO Lock To shift into 4LO Lock, the ignition must be in RUN and the vehicle must be stopped or moving less than 2 mph (3.2 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 4LO Lock button. You must wait for the 4LO Lock indicator light to stop ﬂashing and remain illuminated before shifting your transmission in gear. Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator lights stops ﬂashing before putting the transmission back in gear. It is typical for your vehicle to exhibit signiﬁcant engagement noise and bump when shifting between 4LO and 4HI ranges or from NEUTRAL with the engine running. If the 4LO Lock button is pressed when your vehicle is in gear and/or moving, the 4LO Lock indicator light will ﬂash for 15 seconds and not complete the shift unless your vehicle is moving less than 2 mph (3.2 km/h) and the transmission is in NEUTRAL (N). After 15 seconds the transfer case will return to the setting last chosen. Shifting Out of 4LO Lock To shift from 4LO Lock to 4HI or 4HI Lock, your vehicle must be stopped or moving less than 2 mph (3.2 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of 4LO Lock is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4HI or 4HI Lock button. You must wait for the 4HI or 4HI Lock indicator light to stop ﬂashing and remain illuminated before shifting your transmission into gear. It is typical for your vehicle to exhibit signiﬁcant engagement noise and bump when shifting between 4LO and 4HI ranges or from NEUTRAL with the engine running. 2-27 If the 4HI or 4HI Lock button is pressed when your vehicle is in gear and/or moving, the 4HI or 4HI Lock indicator light will ﬂash for 15 seconds but will not complete the shift unless your vehicle is moving less than 2 mph (3.2 km/h) and the transmission is in NEUTRAL (N). Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator lights stops ﬂashing before putting the transmission back in gear. 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 roll. 2. Set the parking brake. 3. Start the vehicle or turn the ignition to RUN. 4. Connect the vehicle to the towing vehicle. 5. Put the transmission in NEUTRAL (N). 6. Shift the transfer case to 4HI. 7. Simultaneously press and hold the 4HI and 4LO Lock buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 2-28 8. Turn the ignition to LOCK. 9. Place the transmission shift lever in PARK (P). 10. Release the parking brake prior to towing. Shifting Out of NEUTRAL To shift the transfer case out of NEUTRAL, do the following: 1. Set the parking brake and apply the regular brake pedal. 2. Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off. 3. Press the button for the desired transfer case shift position (4HI, 4HI Lock or 4LO Lock). 4. After the transfer case has shifted out of NEUTRAL the red light will go out. 5. You may start the engine and shift the transmission to the desired position. Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator lights stops ﬂashing before putting the transmission back in gear. Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. A chime will activate and the warning light will ﬂash when the parking brake is applied and the vehicle is moving at least 3 mph (5 km/h) for at least three seconds. To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, with the parking brake symbol, to release the parking brake. If the ignition is on when the parking brake is released, the brake system warning light will go off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Verify that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 4-75. 2-29 Shifting Into Park (P) {CAUTION: 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. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, use the steps that follow. If you are pulling a trailer, see Towing a Trailer on page 4-75. 1. Hold the brake pedal down with your right foot and set the parking brake. 2. Move the shift lever into PARK (P) like this: 2-30 (cid:127) Press the button on the end of the shift lever. 3. While still pressing the button, move the lever forward as far as it will go. Let go of the button and the lever. 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). Leaving Your Vehicle With the Engine Running {CAUTION: It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch ﬁre. You or others could be injured. Do not leave your vehicle with the engine running. If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and the parking brake is ﬁrmly set before you leave it. After you move the shift lever into PARK (P), hold the regular brake pedal down. 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). 2-31 Torque Lock If you are parking on a hill and you don’t shift your vehicle 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 Into Park (P) on page 2-30. 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 2-22. 2-32 Parking Over Things That Burn {CAUTION: Things that can burn could touch hot exhaust parts under your vehicle and ignite. Do not park over papers, leaves, dry grass or other things that can burn. Engine Exhaust {CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can not see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: (cid:127) Your exhaust system sounds strange or different. (cid:127) Your vehicle gets rusty underneath. (cid:127) Your vehicle was damaged in a collision. (cid:127) Your vehicle was damaged when driving over high points on the road or over road debris. (cid:127) Repairs were not done correctly. (cid:127) Your vehicle or exhaust system had been modiﬁed improperly. If you ever suspect exhaust is coming into your vehicle: (cid:127) Drive it only with all the windows down to blow out any CO; and (cid:127) Have your vehicle ﬁxed immediately. Running Your Engine While You Are Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier Caution under Engine Exhaust on page 2-33. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control 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 on page 4-52. 2-33 Follow the proper steps to be sure your vehicle will not move. See Shifting Into Park (P) on page 2-30. If you are pulling a trailer, see Towing a Trailer on page 4-75. Mirrors Automatic Dimming Rearview Mirror with Compass and Temperature Display The automatic dimming mirror will automatically dim to the proper level to minimize glare from lights behind you after dark. The mirror also includes a display in the upper right corner of the mirror. The compass reading and the outside temperature will both appear in the display at the same time. The dual display can be turned on or off by brieﬂy pressing either the TEMP or the COMP button. {CAUTION: 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. Do not leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set your parking brake and move the shift lever to PARK (P). {CAUTION: All-wheel drive vehicles with the transfer 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. 2-34 Temperature Display The temperature can be displayed by pressing the TEMP button. Press the TEMP button once brieﬂy to toggle the temperature reading on and off. To alternate the temperature reading between Fahrenheit and Celsius, press and hold the TEMP button for approximately four seconds until the display blinks °F and °C. Press and release the TEMP button to toggle between the Fahrenheit and Celsius readings. After about four seconds of inactivity, the display will stop blinking and display the last selection made. Press and release the TEMP button to toggle the temperature display between Fahrenheit or Celsius. If an abnormal temperature reading is displayed for an extended period of time (30 minutes), see your dealer. Under certain circumstances, a delay in updating the temperature is normal. Automatic Dimming Mirror Operation Press and hold the TEMP button for about eight seconds to turn the automatic dimming feature on or off. The indicator light to the right of the TEMP button will turn on or off to show you when the automatic dimming feature is activated. Once the mirror is turned off, it will remain off until it is turned back on, or until the vehicle is restarted. Compass Operation Press the COMP button once brieﬂy to turn the compass on or off. When the ignition and the compass feature are on, the compass will show two character boxes for about two seconds. After two seconds, the mirror will display the compass heading. Compass Calibration The compass may need calibration if one of the following occurs: If CAL is displayed while driving in the vehicle. (cid:127) After about ﬁve seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic ﬁeld interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item. The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push in the COMP button for about eight seconds or until CAL is displayed. 2-35 (cid:127) (cid:127) To adjust for compass variance, do the following: The compass can be calibrated by driving the vehicle in circles at ﬁve mph (8 km/h) or less until the display reads a direction. 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. 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 zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. 1. Find your current location and variance zone number on the zone map. 2. Press and hold the COMP button for ﬁve seconds until a zone number appears in the display. 3. Press the COMP button on the bottom of the mirror until the new zone number appears in the display. After you stop pressing the button, the display will show a compass direction within a few seconds. 2-36 Cleaning the Mirror Use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing. Outside Power Mirrors The controls are located on the driver’s door armrest. Move the upper selector switch to the left or right to choose the mirror you want to adjust; then press the dots located on the four-way control pad to adjust the mirror. The mirrors may also include a memory function which works in conjunction with the memory seats. See Memory Seat on page 2-51 for more information. Power Folding Mirrors To fold or unfold the mirrors, move the selector switch, located above the mirror control, to the middle position. The mirror control will illuminate. Press the right or left side of the mirror control to fold or unfold the mirrors. You may notice the mirror glass adjust as the mirrors fold in; this is normal. The mirror glass will reposition itself once the mirrors are unfolded. If the mirrors are accidentally folded/unfolded manually, they may shake or ﬂutter at normal driving speeds and may not stay in the unfolded position. If this happens, you will need to reset the mirrors. See “Resetting the Power Folding Mirrors” next. 2-37 Resetting the Power Folding Mirrors You will need to reset the power folding mirrors if: They are accidently manually folded/unfolded. The mirrors will not stay in the unfolded position. The mirrors shake and ﬂutter at normal driving speeds. To reset the power folding mirrors, fold and unfold them at least three times using the mirror controls. This will reset them to their normal detent position. Outside Convex Mirror Your passenger’s side mirror is convex. A convex mirror’s surface is curved so you can see more from the driver’s seat. {CAUTION: A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on your right. Check your inside mirror or glance over your shoulder before changing lanes. 2-38 (cid:127) (cid:127) (cid:127) Outside Heated Mirrors Your vehicle may have this feature. This button is located on the climate control panel. Press this button to warm the heated driver’s and passenger’s outside rearview mirrors to help clear them of ice, snow and condensation. If your vehicle has a rear window defogger, it will also operate when you press this button. See “Rear Window Defogger” under Automatic Climate Control System on page 3-19 for more information. Outside Automatic Dimming Mirror with Curb View Assist Your vehicle may have this feature. The driver’s outside mirror will adjust for the glare of the headlamps behind you. See Automatic Dimming Rearview Mirror with Compass and Temperature Display on page 2-34. Your vehicle’s mirrors will also be capable of performing the curb view assist mirror function. This feature will cause the passenger’s and/or driver’s mirror to tilt to a preselected position when the vehicle is in REVERSE (R). This feature may be useful in allowing
