The right front passenger’s frontal airbag is now enabled (may inﬂate). See Airbag Off Light on page 3-35 for more information. Servicing Your Airbag-Equipped Vehicle Airbags affect how your vehicle should be serviced. There are parts of the airbag system in several places around your vehicle. Your dealer/retailer and the service manual have information about servicing your vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 7-15. {CAUTION: For up to 10 seconds after the ignition is turned off and the battery is disconnected, an airbag can still inﬂate during improper service. You can be injured if you are close to an airbag when it inﬂates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualiﬁed to do so. Adding Equipment to Your Airbag-Equipped Vehicle Q: Is there anything I might add to or change about the vehicle that could keep the airbags from working properly? A: Yes. If you add things that change your vehicle’s frame, bumper system, height, front end or side sheet metal, they may keep the airbag system from working properly. Changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module, steering wheel, instrument panel, roof-rail airbag modules, ceiling headliner or pillar garnish trim, overhead console, front sensors, side impact sensors, rollover sensor module, or airbag wiring can affect the operation of the airbag system. 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. If your vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels on page 5-72 for additional important information. 1-75 Q: Because I have a disability, I have to get my vehicle modiﬁed. How can I ﬁnd out whether this will affect my airbag system? A: If you have questions, call Customer Assistance. 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. In addition, your dealer/retailer and the service manual have information about the location of the airbag sensors, sensing and diagnostic module and airbag wiring. Restraint System Check Checking the Restraint Systems Safety Belts 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. Make sure the safety belt reminder light is working. See Safety Belt Reminders on page 3-33 for more information. Keep safety belts clean and dry. See Care of Safety Belts on page 5-103.

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 have had a crash, do you need new belts or LATCH system (if equipped) parts? After a very minor crash, nothing may be necessary. But the belt assemblies that were used during any crash may have been stressed or damaged. See your dealer/retailer to have your safety belt assemblies inspected or replaced. If your vehicle has the LATCH system and it was being used during a crash, you may need new LATCH system parts. New parts and repairs may be necessary even if the belt or LATCH system (if equipped), was not being used at the time of the crash. If an airbag inﬂates, you will need to replace airbag system parts. See the part on the airbag system earlier in this section. Have your safety belt pretensioners checked if your vehicle has been in a crash, if your airbag readiness light stays on after you start your vehicle, or while you are driving.

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. To activate the theft-deterrent system: 1. Open the door. 2. Lock the door with the Remote Keyless Entry (RKE) transmitter. The security light will illuminate to inform the driver the system is arming. If a door is open when the doors are locked, the security light will ﬂash. 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 the delayed locking feature is turned on, the theft-deterrent system will not start the arming process until the last door is closed and the delay timer has expired. See Delayed Locking on page 2-11. If a locked door is opened without the RKE transmitter, the alarm will go off. The headlamps and parking lamps will ﬂash and the horn will sound for 30 seconds, then will turn off to save the battery power. 2-24 Remember, the theft-deterrent system will not activate if you lock the doors with the vehicle’s 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 RKE transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here is how to avoid setting off the alarm by accident: If you do not want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. (cid:129) Always unlock a door with the RKE transmitter. Unlocking a door any other way will set off the alarm. If you set off the alarm by accident, press unlock on the RKE transmitter or place the key in the ignition and turn it to START to turn it off. The alarm will not stop if you try to unlock a door any other way. Testing the Alarm To test the alarm: 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 RKE 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 Instrument Panel Fuse Block on page 5-111 and Underhood Fuse Block on page 5-113. If the alarm does not sound or the headlamps do not ﬂash, the vehicle should be serviced by your dealer/retailer. 2-25 (cid:129) PASS-Key® III+ The PASS-Key® III+ 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 harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 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. PASS-Key® III+ uses a radio frequency transponder in the key that matches a decoder in your vehicle. PASS-Key® III+ Operation Your vehicle has PASS-Key® III+ (Personalized Automotive Security System) theft-deterrent system. PASS-Key® III+ is a passive theft-deterrent system. The system is automatically armed when the key is removed from the ignition. The system is automatically disarmed when the key is turned to ON/RUN, ACC/ACCESSORY or START from the LOCK/OFF position. You do not have to manually arm or disarm the system. The security light will come on if there is a problem with arming or disarming the theft-deterrent system. When the PASS-Key® III+ system senses that someone is using the wrong key, it prevents the vehicle from starting. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. If the engine does not start and the security light on the instrument panel cluster comes on when trying to start the vehicle, there may be a problem with your theft-deterrent system. Turn the ignition off and try again. 2-26 If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse, see Fuses and Circuit Breakers on page 5-110. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the ﬁrst key may be faulty. See your dealer/retailer who can service the PASS-Key® III+ to have a new key made. In an emergency, contact Roadside Assistance. It is possible for the PASS-Key® III+ decoder to learn the transponder value of a new or replacement key. Up to 10 keys may be programmed for the vehicle. The following procedure is for programming additional keys only. If all the currently programmed keys are lost or do not operate, you must see your dealer/retailer or a locksmith who can service PASS-Key® III+ to have keys made and programmed to the system. See your dealer/retailer or a locksmith who can service PASS-Key® III+ to get a new key blank that is cut exactly as the ignition key that operates the system. To program the new additional key: 1. Verify that the new key has a 1 stamped on it. 2. Insert the original, already programmed, key in the ignition and start the engine. If the engine will not start, see your dealer/retailer for service. 3. After the engine has started, turn the key to LOCK/OFF, and remove the key. 4. Insert the new key to be programmed and turn it to the ON/RUN position within ﬁve seconds of turning the ignition to the LOCK/OFF position in Step 3. The security light will turn off once the key has been programmed. 5. Repeat Steps 1 through 4 if additional keys are to be programmed. If you lose or damage your PASS-Key® III+ key, see your dealer/retailer or a locksmith who can service PASS-Key® III+ to have a new key made. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. 2-27 Ignition Positions Use the key to turn the ignition switch to four different positions. In order to shift out of PARK (P), ignition must be in the ON/RUN or ACC/ACCESSORY and the regular brake pedal must be applied. A (LOCK/OFF): This position locks the ignition and transmission. It is a theft-deterrent feature. The key can only be removed when the ignition is turned to LOCK/OFF. 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:129) Keep your speed at 55 mph (88 km/h) or less for the ﬁrst 500 miles (805 km). (cid:129) Do not drive at any one constant speed, fast or slow, for the ﬁrst 500 miles (805 km). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle. (cid:129) Avoid making hard stops for the ﬁrst 200 miles (322 km) or so. During this time the 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:129) Do not tow a trailer during break-in. See Towing a Trailer on page 4-55 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. 2-28 Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is all the way in. If it is, turn the steering wheel left and right while you turn the key hard. If none of this works, then your vehicle needs service. B (ACC/ACCESSORY): This position lets things like the radio and the windshield wipers operate while the engine is off. Lengthy operation of features such as the radio in the ACC/ACCESSORY ignition position and the ON/RUN position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the ACC/ACCESSORY ignition position for a long period of time. C (ON/RUN): This is the position for driving. It is the position the ignition switch returns to after the engine starts, and the key is released. The battery could be drained if you leave the key in the ACC/ACCESSORY or ON/RUN position with the engine off. You may not be able to start your vehicle if the battery is allowed to drain for an extended period of time. D (START): This position starts the engine. Key In the Ignition Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound, when you open the driver’s door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transmission. Also, always remember to lock the doors. The battery could be drained if you leave the key in the ignition while your vehicle is parked. You may not be able to start your vehicle after it has been parked for an extended period of time. Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: (cid:129) Audio System (cid:129) Sunroof (cid:129) Power Windows The sunroof and power windows will continue to work up to 10 minutes after the key is turned to LOCK/OFF or until any door is opened. The radio will continue to work for up to 10 minutes after the key is turned to LOCK/OFF or until the driver’s door is opened. 2-29 Starting the Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position – this is a safety feature. To restart when you are 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. Starting Procedure 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. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. Your vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in START for many seconds, cranking will be stopped after 15 seconds to prevent cranking motor damage. 2-30 To prevent gear damage, this system also prevents cranking if the engine is already running. Engine cranking can be stopped by turning the ignition switch to the ACC/ACCESSORY or LOCK/OFF position. Notice: Cranking the engine for long periods of time, by returning the key to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. 2. If the engine does not start after 5-10 seconds, especially in very cold weather (below 0°F or −18°C), it could be ﬂooded with too much gasoline. Try pushing the accelerator pedal all the way to the ﬂoor and holding it there as you hold the key in START for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key and accelerator. If the vehicle starts brieﬂy but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. Notice: The 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/retailer. If you do not, your engine might not perform properly. Any resulting damage would not be covered by your vehicle’s warranty. Engine Coolant Heater The engine coolant heater, if available, can help in cold weather conditions at or below 0°F (−18°C) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting your vehicle. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above 0°F (−18°C). 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 do not, 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/retailer in the area where you will be parking your vehicle. The dealer/retailer can give you the best advice for that particular area. 2-31 Automatic Transmission Operation Your vehicle has a Hydra-Matic® 6L80 automatic transmission, and has an electronic shift position indicator within the instrument panel cluster. This display comes on when the ignition key is turned to the ON/RUN position. There are several different positions for the shift lever. PARK (P): This position locks the rear wheels. It is the best position to use when you start your engine because your vehicle cannot move easily. When parked on a hill, especially when the vehicle has a heavy load, you may notice an increase in the effort to shift out of PARK (P). See Torque Lock (Automatic Transmission) under Shifting Into PARK (P) on page 2-41 for more information. 2-32 {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 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 2-41. If you are pulling a trailer, see Towing a Trailer on page 4-55. 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 the transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-39. NEUTRAL (N): In this position, the engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed. {CAUTION: Shifting into a drive gear while the 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. DRIVE (D): This position is for normal driving. It provides the best fuel economy for your vehicle. If you need more power for passing, and you are: (cid:129) Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. (cid:129) Going about 35 mph (55 km/h) or more, push the accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has 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 a lower gear selection if the transmission shifts too often. Downshifting the transmission in slippery road conditions could result in skidding, see Skidding under Loss of Control on page 4-12. MANUAL MODE (M): This position lets drivers select the range of gears appropriate for current driving conditions. If your vehicle has this feature, see Driver Shift Control (DSC) later in this section. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. 2-33 SECOND (2): This position reduces vehicle speed without using the brakes. Use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you may also want to use the brakes off and on. FIRST (1): This position reduces vehicle speed without using the brakes. Use it for major/severe downgrades and off-road driving where the vehicle would otherwise accelerate due to steepness of grade. When you shift to SECOND (2) or FIRST (1) it provides the lowest gear appropriate to your current road speed and continues to downshift as the vehicle slows, eventually downshifting to the selected gear. Your vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine will be able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position and vehicle load. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this may appear to be a delayed shift, however the transmission is operating normally. Your vehicle’s transmission uses adaptive shift controls that compares key shift parameters to pre-programmed ideal shifts stored in the transmissions computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with a heavy load or when temperature changes. During this adaptive shift controls process, shifting may feel different as the transmission determines the best settings. When temperatures are very cold, the Hydra-Matic® 6L80 automatic transmission’s gear shifting may be delayed providing more stable shifts until the engine warms up. Shifts may be more noticeable with a cold transmission. This difference in shifting is normal. 2-34 Driver Shift Control (DSC) Your vehicle has a Driver Shift Control (DSC). The DSC controls the vehicle’s transmission and vehicle speed while driving down hill or towing a trailer by allowing you to select a desired range of gears. To use this feature: 1. Move the shift lever to the MANUAL MODE (M). This will force a downshift from the current gear, for gears 3 through 6. 2. Press the (+) plus or (−) minus button on the left side of the steering wheel, to select the desired range of gears for your current driving conditions. When in the MANUAL MODE (M) a number will display next to the M, indicating the maximum available gear. The DIC display will show the message MANUAL SHIFT on the ﬁrst line and the maximum available gear will be displayed on the second line. See Driver Information Center (DIC) on page 3-49 and DIC Operation and Displays (Using DIC Buttons) on page 3-49 or DIC Operation and Displays (Using Trip Odometer Reset Stem) on page 3-54 for more information. The number displayed in the DIC is the highest gear available. The transmission will be limited to the gear selected and lower gears. Shifting will occur normally while driving, however the cluster will continue to display the maximum available gear. Higher gears will not be available unless the selection is changed to include higher gears using the (+) plus button. Grade Braking is not available when the Driver Shift Control is active. See Tow/Haul Mode on page 2-36 and Towing a Trailer on page 4-55 for more information. While using the DSC, cruise control and the tow/haul mode can be used. 2-35 Tow/Haul Mode Transfer Case Dial 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 dial is located to the right of the instrument panel cluster. Use this switch to shift into and out of the different Full-Time Four-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 4-55 for more information. Full-Time Four-Wheel Drive The transfer case on your Full-Time Four-Wheel Drive vehicle is designed to constantly send the engine’s driving power to all four wheels for extra traction. To get the most out of Full-Time Four-Wheel Drive, you must be familiar with its operation. Notice: Driving on pavement in Four-Wheel High Lock or Four Wheel Low Lock for extended periods may cause premature wear on your vehicle’s powertrain and tires. Do not drive in Four-Wheel High Lock or Four-Wheel Low Lock on pavement for extended periods. 2-36 The transfer case is a part of the Full-Time Four-Wheel Drive system and allows the following four different modes of operation: 4 m(Full-Time Four-Wheel Drive): This setting is used for driving in most street and highway situations. It can be used for light or variable off-road conditions. 4 mQ(Four-Wheel-High Lock): Use this mode when you need extra traction in most off-road situations such as sand, mud, snow, or level, rocky trails. 4 nQ(Four-Wheel-Low Lock): This mode delivers extra torque to all four wheels and is used for extreme off-road conditions. Choose Four-Wheel-Low Lock while driving off-road in 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 4-6. Notice: Operating your vehicle in Four-Wheel-Low 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 Four-Wheel-Low 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 2-40. N (NEUTRAL): Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-51 or Towing Your Vehicle on page 4-51 for more information. Indicator lights in the dial shows 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, take your vehicle to your dealer/retailer for service. An indicator light will ﬂash while shifting the transfer case. It will remain on 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/retailer for service. See “Service 4WD message” under Driver Information Center (DIC) on page 3-49. 2-37 Shifting between Four-Wheel High and Four-Wheel-High Lock With the vehicle traveling less than 40 mph (64 km/h), turn the dial to the Four-Wheel High or Four-Wheel-High Lock position. The indicator light on the dial will ﬂash while shifting. It will remain on 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 Four-Wheel-Low Lock To shift into Four-Wheel-Low Lock, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into Four-Wheel Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the dial to the Four-Wheel-Low Lock position. You must wait for the Four-Wheel-Low Lock indicator light on the dial to stop ﬂashing and remain lit before shifting the transmission in gear. When the transfer case is shifted into Four-Wheel-Low Lock position a StabiliTrak® indicator light will come on to show that the system has been turned off and a message will show in the DIC. See DIC Warnings and Messages on page 3-56 for more information. Notice: Shifting the transmission into gear before the indicator light stops ﬂashing could cause damage to the transfer case. Always wait until the indicator light stops ﬂashing before putting the transmission back in gear. It is normal for your vehicle to have engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High or Four-Wheel-High Lock ranges or from NEUTRAL with the engine running. If the Four-Wheel-Low Lock position is selected when your vehicle is in gear and/or moving, the Four-Wheel Low Lock indicator light will ﬂash for 15 seconds and not complete the shift unless your vehicle is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). After 15 seconds the transfer case will return to the setting last chosen. 2-38 Shifting Out of Four-Wheel Low Lock To shift from Four-Wheel-Low Lock to Four-Wheel High or Four-Wheel-High Lock, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of Four-Wheel-Low Lock is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the dial to the Four-Wheel High or Four-Wheel-High Lock position. You must wait for the Four-Wheel High or Four-Wheel-High Lock indicator light to stop ﬂashing and remain lit before shifting your transmission into gear. It is normal for your vehicle to have engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High or Four-Wheel-High Lock ranges or from NEUTRAL with the engine running. If the Four-Wheel High or Four-Wheel-High Lock position is selected when your vehicle is in gear and/or moving, the Four-Wheel High or Four-Wheel-High Lock indicator light will ﬂash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (5 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 light 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 and apply the regular brake pedal. See Parking Brake on page 2-40 3. Start the vehicle or turn the ignition to ON/RUN. 4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to Two-Wheel Drive High. 6. Turn the transfer case dial clockwise to NEUTRAL position. The transfer case will not shift to NEUTRAL unless this position is held for 10 seconds. The NEUTRAL light will come on and then the dial can be slowly released. The dial will be in the Four-Wheel Low Lock position but the transfer case will be in NEUTRAL with the NEUTRAL light on. 7. If the engine is running, make sure that the transfer case is in NEUTRAL (N) by shifting the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second. 8. Turn the ignition to ACC/ACCESSORY, which will turn the engine off. 9. Place the transmission shift lever in PARK (P). 10. Release the parking brake prior to moving the vehicle. 11. Turn the ignition to LOCK/OFF. 2-39 Shifting Out of NEUTRAL To shift 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. Turn the transfer case dial to Four-Wheel High, Four-Wheel High Lock or Four-Wheel Low Lock. After the transfer case has shifted out of NEUTRAL the NEUTRAL light will go out. 4. Release the parking brake prior to moving the vehicle. Notice: Shifting the transmission into gear before the requested mode indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the mode indicator lights to stop ﬂashing before shifting the transmission into gear. 5. Start the engine and shift the transmission to the desired position. 2-40 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. Make sure 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 4-55. 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 4-55. 1. Hold the brake pedal down with your foot and set the parking brake. See Parking Brake on page 2-40 for more information. 2. Move the shift lever into PARK (P) by pressing the button on the shift lever and pushing the lever all the way toward the front of the vehicle. 3. Turn the ignition key to LOCK/OFF. 4. Remove the key and take it with you. If you can leave your vehicle with the key, 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 your parking brake is ﬁrmly set before you leave it. After you have moved 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 pressing the button on the console shift lever. If you can, it means that the shift lever was not fully locked into PARK (P). 2-41 Torque Lock If you are parking on a hill and you do not 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 Into PARK (P) on page 2-41. 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) This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: (cid:129) Prevent ignition key removal unless the shift lever is in PARK (P) with the shift lever button fully released, and (cid:129) Prevent movement of the shift lever out of PARK (P), unless the ignition is in ON/RUN or ACC/ACCESSORY and the regular brake pedal is applied. The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery. If your vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting on page 5-40 for more information. To shift out of PARK (P) use the following: 1. Apply the brake pedal. 2. Then press the shift lever button. 3. Move the shift lever to the desired position. 2-42 If you still are unable to shift out of PARK (P): 1. Fully release the shift lever button. 2. While holding down the brake pedal, press the shift lever button again. 3. Move the shift lever to the desired position. If you still cannot move the shift lever from PARK (P), consult your dealer/retailer or a professional towing service. 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 cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: (cid:129) The exhaust system sounds strange or different. (cid:129) Your vehicle gets rusty underneath. (cid:129) Your vehicle was damaged in a collision. (cid:129) Your vehicle was damaged when driving over high points on the road or over road debris. (cid:129) Repairs were not done correctly. (cid:129) Your vehicle or the exhaust system has been modiﬁed improperly. If you ever suspect exhaust is coming into your vehicle: (cid:129) Drive it only with all the windows down to blow out any CO; and (cid:129) Have your vehicle ﬁxed immediately. 2-43 Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {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 the parking brake and move the shift lever to PARK (P). {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 2-43. 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 4-36. 2-44 {CAUTION: Full-time four-wheel drive vehicles with the transfer case in NEUTRAL will allow the vehicle to roll, even if the shift lever is in PARK (P). So, be sure the transfer case is in a drive gear — not in NEUTRAL. Always set the parking brake. Follow the proper steps to be sure your vehicle will not move. See Shifting Into PARK (P) on page 2-41. If you are pulling a trailer, see Towing a Trailer on page 4-55. Mirrors Automatic Dimming Rearview Mirror with Compass and Temperature Display Your vehicle may have this mirror. When on, an automatic dimming mirror will dim to the proper level to minimize glare from lights behind you after dark. The mirror also includes a dual display in the upper right corner of the mirror with the compass reading and the outside temperature. Yb: Brieﬂy press this button to turn the display on or off. Your vehicle may also have a Rear Vision Camera. See Rear Vision Camera on page 2-50. 2-45 Compass Operation Press the compass/temperature button once brieﬂy to turn the compass on or off. Compass Calibration The compass may need calibration if the following occurs: 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 compass/temperature button for approximately eight seconds or until CAL is displayed. The compass can only be calibrated by driving the vehicle forward in circles at 5 mph (8 km/h) or less until the display reads a direction. Do not attempt to calibrate the compass by driving in reverse. Automatic Dimming Mirror Operation O: Press this button to turn the automatic dimming feature on or off. The indicator light to the left of the button will turn on to indicate when the feature is on. Once the mirror is turned off, it will remain off until it is turned back on, or until the vehicle is restarted. Temperature Display The temperature can be displayed by pressing the compass/temperature button. Pressing the compass/temperature button once brieﬂy, will toggle the temperature reading on and off. To alternate the temperature reading between Fahrenheit and Celsius, press and hold the compass/temperature button for approximately four seconds until the display blinks F and C. Press and release the compass/temperature button to toggle between the Fahrenheit and Celsius readings. After approximately four seconds of inactivity, the display will stop blinking and display the last selection made. If an abnormal reading is displayed, for an extended period of time, please consult your dealer/retailer. Under certain circumstances, a delay in updating the temperature is normal. 2-46 (cid:129) 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 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: 1. Find your current location and variance zone number on the following zone map. 2. Press and hold the compass/temperature button for ﬁve seconds until a zone number appears in the display. Cleaning the Mirror When 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. 2-47 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 Foldaway Mirrors” next. Resetting the Power Foldaway Mirrors You will need to reset the power foldaway mirrors if the following occurs: The mirrors are accidentally obstructed while folding. They are accidentally 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 foldaway mirrors, fold and unfold them three times using the mirror controls. This will reset them to their normal position. Outside Power Foldaway Mirrors If your vehicle has outside power foldaway mirrors, the controls are located on the driver’s door armrest. (cid:129) Press (A) to select the driver side mirror. Then press the arrows located on the four-way control pad to adjust the mirror. Press (A) again to deselect this mirror. (cid:129) Press (B) to select the passenger side mirror. Then press the arrows located on the four-way control pad to adjust the mirror. Press (B) again to deselect this mirror. (cid:129) Press (C), to fold the mirrors out to the driving position. (cid:129) Press (D) to fold the mirrors in to the folded position. 2-48 (cid:129) (cid:129) (cid:129) (cid:129) Outside Automatic Dimming Mirror If the vehicle has this feature, the driver’s outside mirror adjusts for the glare of the headlamps behind you. See Automatic Dimming Rearview Mirror with Compass and Temperature Display on page 2-45. Park Tilt Mirrors The vehicle’s outside mirrors can also perform a park tilt function. This causes 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 viewing the curb when parallel parking. When the vehicle is shifted out of REVERSE (R) and a short delay has occurred, the passenger’s and/or driver’s mirror will return to its original position. To change the preselected tilt position, adjust the mirrors to the desired position while the vehicle is in REVERSE (R). When the vehicle is shifted out of REVERSE (R), this new position is saved in memory as the tilt position. This feature can be enabled/disabled through the Driver Information Center. See DIC Vehicle Customization (With DIC Buttons) on page 3-63 for more information. Outside Convex Mirror {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. The passenger side mirror is convex. A convex mirror’s surface is curved so more can be seen from the driver seat. It also makes things, like other vehicles, look farther away than they really are. Outside Heated Mirrors The vehicle may have outside heated mirrors which help clear them of condensation, snow, and ice. When the rear window defogger button is pressed, the heated mirrors are also turned on. See “Rear Window Defogger” under Dual Automatic Climate Control System on page 3-22 for more information. 2-49 Object Detection Systems Rear Vision Camera Your vehicle may be equipped with a rear vision camera system. Read this entire section before using the camera system. The rear vision camera system is designed to help the driver when backing up by displaying a view of the area behind the vehicle. When the driver shifts the vehicle into REVERSE (R), the video screen will automatically slide out from the rear view mirror. Once the driver shifts out of REVERSE (R), the video screen will slide back into the rear view mirror after a delay. If your vehicle does not have a rearview mirror slide-out video screen, your vehicle may have a navigation radio system. See the Navigation System manual for more information on the rear vision camera display video screen. Turning the Rear Vision Camera System On or Off To turn off the rear vision camera system, do the following: 1. Shift into (P) PARK. 2. Turn the ignition key to the RUN position. 3. Press the right button on the inside rear view mirror brieﬂy; the right green light indicator will turn off. The rear camera vision display is now disabled. To turn on the rear camera vision feature again, press the right button on the inside rear view mirror brieﬂy. The green light indicator will illuminate. The rear camera vision system is now enabled and the display will slide out from the mirror normally. 2-50 Cleaning the Camera Screen To manually slide out the rear camera screen for cleaning, do the following: 1. Shift into (P) PARK. 2. Turn the ignition key to the RUN position. 3. Press and hold the right button on the inside rear view mirror for ﬁve seconds. The display will slide out from the mirror for 30 seconds; the right green LED indicator will remain illuminated. The camera screen will not be on when it slides out of the mirror. 4. If additional time is required for cleaning, repeat step 3. To resume normal operation, press the right button momentarily while the rear camera screen is out or wait 30 seconds for screen to slide back into the mirror. For more information on the automatic dimming, compass, and temperature features of the mirror, see Automatic Dimming Rearview Mirror with Compass and Temperature Display on page 2-45. {CAUTION: The Rear Vision Camera (RVC) system does not replace driver vision. RVC does not: (cid:129) Detect objects that are outside the camera’s ﬁeld of view, below the bumper, or underneath the vehicle. (cid:129) Detect children, pedestrians, bicyclists, or pets. Do not back the vehicle by only looking at the rear vision camera screen, or use the screen during longer, higher speed backing maneuvers or where there could be cross-traffic. Your judged distances using the screen will differ from actual distances. So if you do not use proper care before backing up, you could hit a vehicle, child, pedestrian, bicyclist, or pet, resulting in vehicle damage, injury, or death. Even though the vehicle has the RVC system, always check carefully before backing up by checking behind and around your vehicle. 2-51 Rear Vision Camera Location The image is provided by the camera located on the rear bumper. The camera uses a special lens. The distance of the image that appears on the screen differs from the actual distance. The area displayed by the camera is limited. The camera does not display objects which are close to either corner of the bumper or under the bumper. The spare tire and carrier extends rearward of the rear bumper. The area displayed on the screen may vary according to vehicle orientation or road conditions. The following illustration shows the ﬁeld of view that the camera provides. 2-52 Notice: The spare tire extends farther away from rear of the vehicle than the trailer hitch shown on rear vision camera display. Your spare tire could hit an object even though there appears to be enough distance on the display between the trailer hitch and objects behind you causing vehicle or property damage. Do not use this system to judge the distance between the spare tire and objects behind you. When the System Does Not Seem To Work Properly The rear vision camera system may not work properly or display a clear image in the following situations: In the dark. (cid:129) When the sun or the beam of headlights is shining directly into the camera lens. If ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. If the back of the vehicle is in an accident, the position and mounting angle of the camera may change or the camera may be affected. Be sure to have the camera and its position and mounting angle checked at your dealer. (cid:129) Extreme high or low temperatures or extreme temperature changes can affect the image displayed.
