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. 2-8 Power Door Locks The power door lock switches are located 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. Press the lock symbol twice to override this feature and lock all of the doors immediately. See Delayed Locking on page 2-9 for more information. K (Unlock): To unlock the doors, press the unlock symbol. Delayed Locking When locking the doors with the power lock switch or the keyless entry transmitter and a door or the liftgate (if equipped) is open, the delayed locking feature will delay locking the doors until ﬁve seconds after the last door is closed. You will hear three chimes to signal that the delayed locking feature is in use. Pressing the power lock switch or the lock button on the keyless entry transmitter twice will override the delayed locking feature and immediately lock all the doors. You can turn the delayed locking feature off or back on again by doing the following: 1. Press and hold the power door lock switch in the lock position. 2.

You or others could be injured and the window could be damaged. Before you use express override, make sure that all people and obstructions are clear of the midgate window path. Midgate Window Express Override Mode If window movement is stopped, either by an obstruction or weather conditions such as severe icing, auto-reversal to a partially open position will occur. The midgate window function will return to normal operation once the obstruction or condition is removed. If you override this function and activate express override mode, window express functions are disabled. In this mode, the window can only be operated manually by pressing and holding the midgate window switch or the global window button within two seconds after the midgate window has stopped at a partially open position. The express override mode can only be activated immediately following a window auto-reversal. Midgate Window Error/Jog Mode If the midgate window has detected abnormal operating conditions which may lead to system damage or malfunction, the midgate window will automatically go into Error/Jog mode. In this mode, window express functions are disabled and the window can only be operated manually by pressing the midgate window switch or the global window button. The window will move slightly and stop. Press and hold the window switch or global window button to continue to close the window a small amount at a time. 2-21 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. To Exit Error/Jog Mode 1. Ensure normal midgate window operating conditions have been resumed. 2. Press and hold the midgate window down switch approximately one second to engage window express-down. 3. Release the window down switch and allow the window to fully open. Do not activate any window function switches once glass movement has been initiated. 4. Press the midgate glass up switch and visually conﬁrm that the express-up has been accomplished. 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. 2-22 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 3-43. 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. 2-23 (cid:127) 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 5-103 and Underhood Fuse Block on page 5-107. If the alarm does not sound or the headlamps do not ﬂash, the vehicle should be serviced by your dealer. 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 Instrument Panel Fuse Block on page 5-103 and Underhood Fuse Block on page 5-107. See your dealer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program on page 7-6. 2-24 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 4-68 for more information. Ignition Positions Use the key to turn the ignition switch to four different positions. A (LOCK): This position locks the ignition and transmission. It is a theft-deterrent feature. You will only be able to remove the key when the ignition is turned to LOCK. 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 in all the way. If none of this works, then your vehicle needs service. 2-25 B (ACCESSORY): This position lets you use things like the radio and the windshield wipers when the engine is off. Notice: Lengthy operation of features such as the radio in the accessory ignition position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the accessory ignition position for a long period of time. C (RUN): This is the position for driving. D (START): This position starts the 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 or until one of the doors is opened. Starting Your Engine Your vehicle is equipped with Starter Motor Control. This feature assists in starting the engine and protects the electrical system. This feature may cause the engine to crank even after the ignition key is not in START. Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position — that 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. 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 disengage the starter motor, cause your battery to be drained much sooner, and add excessive heat that can damage your starter motor. Try not to hold the key in START for longer than 15 seconds and wait about 15 seconds between each try to help avoid draining your battery or damaging your starter. 2. If it does not 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. 2-26 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 will not 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. 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 will 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. Your vehicle may also have an internal thermostat in the plug end of the cord. This will prevent operation of the engine coolant heater when the temperature is at or above 0°F (-18°C) as noted on the cord. 2-27 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. 2-28 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 will be parking your vehicle. The dealer can give you the best advice for that particular area. 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 is the best position to use when you start your engine because your vehicle cannot move easily. {CAUTION: {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 2-37. If you are pulling a trailer, see Towing a Trailer on page 4-68. 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 2-37. 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 4-52. 2-29 NEUTRAL (N): In this position, your engine does not connect with the drive wheels. To restart when you are 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. DRIVE (D): This position is for normal driving. If you need more power for passing, and you are: (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 will 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). 2-30 Tow/Haul Mode Your vehicle is equipped with a tow/haul mode. The button is located on the instrument panel to the right of the steering wheel. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” under Towing a Trailer on page 4-68 for more information. 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 will not 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. 2-31 All-Wheel Drive All-wheel drive sends your engine’s driving power to all four wheels for extra traction. To get the most 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. Transfer Case Buttons 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 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. 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 4-10. 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. 2-32 If the SERVICE 4WD message stays on, you should take your vehicle to your dealer for service.

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 lit 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. {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 2-36. N (NEUTRAL): Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-64 or Towing Your Vehicle on page 4-64 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. 2-33 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 lit 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.

It is normal for your vehicle to have 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 lit before shifting your transmission into gear. It is normal for your vehicle to have engagement noise and bump when shifting between 4LO and 4HI ranges or from NEUTRAL with the engine running. 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 light stops ﬂashing before putting the transmission back in gear. 2-34 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. 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.

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 4-68. 2-36 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 4-68. 1. Hold the brake pedal down with your right foot and set the parking brake. 2. Move the shift lever into PARK (P) by pressing and holding the button on the end of the shift lever and moving the lever forward as far as it will go. 3. Turn the ignition key to LOCK. 4. 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 was not fully locked into PARK (P). 2-37 Torque Lock If you are parking on a hill and you do not 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 2-37. 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 the regular brakes before you can shift from PARK (P) when the ignition is in RUN. See Automatic Transmission Operation on page 2-28. 2-38 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:127) Your exhaust system sounds strange or different. (cid:127) Your vehicle gets rusty underneath. (cid:127) Your vehicle was damaged in a collision. CAUTION: (Continued) (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. CAUTION: (Continued) 2-39 {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). 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 2-39. 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 4-48. 2-40 {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. Follow the proper steps to be sure your vehicle will not move. See Shifting Into Park (P) on page 2-37. If you are pulling a trailer, see Towing a Trailer on page 4-68. Mirrors Automatic Dimming Rearview Mirror with OnStar®, Compass and Temperature Display For information on the OnStar® system see OnStar® System on page 2-48 or consult the OnStar® manual.

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, a 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 the COMP button for about eight seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at ﬁve mph (8 km/h) or less until a direction is displayed. Compass Variance Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, the 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 the vehicle is outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. 2-42 (cid:127) (cid:127) To adjust for compass variance, do the following: 1.

Changes and modiﬁcations to this system by other than an authorized service facility could void authorization to use this equipment. Programming the HomeLink® Transmitter Do not use the HomeLink® Transmitter with any garage door opener that does not have the “stop and reverse” feature. This includes any garage door opener model manufactured before April 1, 1982. If you have a newer garage door opener with rolling codes, please be sure to follow steps 6 through 8 to complete the programming of your HomeLink® Transmitter. Read the instructions completely before attempting to program the HomeLink® Transmitter. Because of the steps involved, it may be helpful to have another person available to assist you in programming the transmitter. Keep the original transmitter for use in other vehicles as well as for future HomeLink® programming. It is also recommended that upon the sale of the vehicle, the programmed HomeLink® buttons should be erased for security purposes. Refer to “Erasing HomeLink® Buttons” or, for assistance, contact HomeLink® on the internet at: www.homelink.com or by calling 1-800-355-3515. Be sure that people and objects are clear of the garage door or gate operator you are programming. When programming a garage door, it is advised to park outside of the garage. It is recommended that a new battery be installed in your hand-held transmitter for quicker and more accurate transmission of the radio frequency. Programming HomeLink® Your vehicle’s engine should be turned off while programming the transmitter. Follow these steps to program up to three channels: 1. Press and hold down the two outside buttons, releasing only when the indicator light begins to ﬂash, after 20 seconds. Do not hold down the buttons for longer than 30 seconds and do not repeat this step to program a second and/or third transmitter to the remaining two HomeLink® buttons. 2. Position the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the HomeLink® buttons while keeping the indicator light in view. 2-51 6. Locate in the garage, the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. This can usually be found where the hanging antenna wire is attached to the motor-head unit. 7. Firmly press and release the “Learn” or “Smart” button. The name and color of the button may vary by manufacturer. You will have 30 seconds to start Step 8. 8. Return to the vehicle. Firmly press and hold the programmed HomeLink® button for two seconds, then release. Repeat the press/hold/release sequence a second time, and depending on the brand of the garage door opener (or other rolling code device), repeat this sequence a third time to complete the programming. HomeLink® should now activate your rolling-code equipped device. To program the remaining two HomeLink® buttons, begin with Step 2 of “Programming HomeLink®.” Do not repeat Step 1. 3. Simultaneously press and hold both the desired button on HomeLink® and the hand-held transmitter button. Do not release the buttons until Step 4 has been completed. Some entry gates and garage door openers may require you to substitute Step 3 with the procedure noted in “Gate Operator and Canadian Programming” later in this section. 4. The indicator light will ﬂash slowly at ﬁrst and then rapidly after HomeLink® successfully receives the frequency signal from the hand-held transmitter. Release both buttons. 5. Press and hold the newly-trained HomeLink® button and observe the indicator light. If the indicator light stays on constantly, programming is complete and your device should activate when the HomeLink® button is pressed and released. To program the remaining two HomeLink® buttons, begin with Step 2 under “Programming HomeLink®.” Do not repeat Step 1 as this will erase all of the programmed channels. If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with Steps 6 through 8 following to complete the programming of a rolling-code equipped device (most commonly, a garage door opener). 2-52 Gate Operator and Canadian Programming Canadian radio-frequency laws require transmitter signals to “time out” or quit after several seconds of transmission. This may not be long enough for HomeLink® to pick up the signal during programming. Similarly, some U.S. gate operators are manufactured to “time out” in the same manner. If you live in Canada, or you are having difficulty programming a gate operator by using the “Programming HomeLink®” procedures (regardless of where you live), replace Step 3 under “Programming HomeLink®” with the following: Continue to press and hold the HomeLink® button while you press and release every two seconds (cycle) your hand-held transmitter until the frequency signal has been successfully accepted by HomeLink®. The indicator light will ﬂash slowly at ﬁrst and then rapidly. Proceed with Step 4 under “Programming HomeLink®” to complete. Using HomeLink® Press and hold the appropriate HomeLink® button for at least half of a second. The indicator light will come on while the signal is being transmitted. Erasing HomeLink® Buttons To erase programming from the three buttons do the following: 1. Press and hold down the two outside buttons until the indicator light begins to ﬂash, after 20 seconds. Do not hold the two outside buttons for longer than 30 seconds. 2. Release both buttons. HomeLink® is now in the train (learning) mode and can be programmed at any time beginning with Step 2 under “Programming HomeLink®” shown earlier in this section. Individual buttons can not be erased, but they can be reprogrammed. See “Reprogramming a Single HomeLink® Button” following this section. 2-53 Reprogramming a Single HomeLink® Button To program a device to HomeLink® using a HomeLink® button previously trained, follow these steps: 1. Press and hold the desired HomeLink® button. Do not release the button. 2. The indicator light will begin to ﬂash after 20 seconds. While still holding the HomeLink® button, proceed with Step 2 under “Programming HomeLink®” shown earlier in this section.
