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 “Lock Feedback” and “Unlock Feedback” under DIC Vehicle Customization on page 3-60 for more information. 2-5 (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 will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it is 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 “Lock Feedback” and “Unlock Feedback” under DIC Vehicle Customization on page 3-60 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. 2-6 To replace the battery in the keyless entry transmitter, do the following: 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. 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. 3. Align the covers and snap them together. 4. Resynchronize the transmitter. See “Resynchronization” following this information. 5. Check the operation of the transmitter. 2-7 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. 2-8 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 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. Press unlock twice on the remote keyless entry transmitter. This feature will not operate if the key is in the ignition. You can also program this feature using the Driver Information Center (DIC). See “Door Lock Delay” under DIC Vehicle Customization on page 3-60. 2-9 Programmable Automatic Door Locks Your vehicle is equipped with an automatic lock/unlock feature which enables you to program your vehicle’s power door locks. You can program this feature through the Driver Information Center (DIC). See DIC Vehicle Customization on page 3-60 for more information on DIC programming. 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. To use the locks, do the following: 1. Open one of the rear doors. 2. Move the lever forward to engage the rear door security lock. 3. Close the door. 4. Do the same thing to the other rear door. The rear doors 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. Move the lever rearward to disengage the child security lock feature. 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. 2-10 Midgate® {CAUTION: It can be dangerous to drive with the cargo area covered and the tailgate and the midgate® 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 cargo CAUTION: (Continued) CAUTION: (Continued) covers on and the tailgate and midgate® open or if electrical wiring or other cable connections must pass through the seal between the body and the midgate®: (cid:127) Make sure all windows are shut. (cid:127) Turn the fan on your heating or cooling system to its highest speed on the setting that brings in outside air. This will force outside air into your vehicle. See Dual Automatic Climate Control System on page 3-22. If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust on page 2-42. 2-11 (cid:127) Midgate® Operation Your vehicle is equipped with a midgate and a removable rear glass panel. The midgate allows you to extend the length of your vehicle’s cargo area. The following are the main components of the midgate system: A. Latch Levers B. Grab Handles C. Glass-Catch Release Button D. Glass Lock Knobs E. Window Retaining Tabs F. Midgate Release Handle G. Window Alignment Arrows 2-12 Rear Glass Removal and Storage {CAUTION: If the removable rear glass is not stored properly, it could be thrown about the vehicle in a crash or sudden maneuver. People in the vehicle could be injured. Whenever you store the rear glass in the vehicle, always be sure that it is stored securely in the midgate storage pocket. Do not remove the rear glass when the rear defroster is on. If you remove the rear glass with the rear defroster on, you may see a discharge spark coming from the latch area. To remove the rear glass do the following: 1. Fold the rear seats. See Rear Seat Operation on page 1-7 for more information. The front seats may have to be moved forward slightly to allow the rear seats to fold completely. Although the rear glass can be removed without folding the rear seats, you will not be able to access the rear glass storage pocket. Be sure to fold the seats before removing the rear glass. 2. Squeeze and pull down the latch levers (A), located near the upper corners of the rear glass, to unlatch. Once unlatched, the glass-catch release button (C) will catch the rear glass and prevent it from falling forward. 2-13 3. While holding the rear glass in place, press the glass-catch release button (C) and pull the top of the rear glass toward you using the grab handle(s) (B) located at the top of the rear glass. 4. With the rear glass tilted toward you, lift it out from the lower window frame channel. Use the grab handles to assist you in removing the rear glass. 2-14 5. Load the rear glass into the storage pocket in the midgate, guiding the lower edge of the rear glass behind the three rear glass retaining tabs (E). Hold the rear glass ﬂat against the storage pocket, with grab handles facing you, until the next step. 6. Turn both glass lock knobs (D), located at both top corners of the storage pocket, to the locked position. Push in on the corner of the rear glass to allow the lock knob to engage more easily. Once both glass lock knobs are in the locked position, the rear glass is securely stored. 2-15 Reinstalling the Rear Glass To reinstall the rear glass, do the following: 1. Squeeze and pull down the latch levers (A), located near the upper corners of the rear glass, to unlatch. 7. Push both latch levers up to the locked position. You should hear a click when each latch lever locks correctly. The rear seats can be returned to the normal position when the rear glass is out and stored properly in the storage pocket. 2-16 2. Hold the rear glass in place with one hand and turn the glass lock knobs, located at both top corners of the glass storage pocket, to the unlocked position. 3. Pull the rear glass out from the storage pocket using the grab handles. Be sure to align the rear glass side-to-side using the alignment arrows (G). 4. With the rear glass tilted at an angle, place the bottom edge in the lower channel of the window frame. 5. Apply a ﬁrm downward pressure and then push the rear glass ﬂat against the window frame. Use the grab handles at the top of the rear glass to assist you. 2-17 To lower the midgate, do the following: 1. Fold the rear seats. The front seats might have to be moved forward slightly to allow the rear seats to fold. See Rear Seat Operation on page 1-7 for more information. 6. Push the rear glass ﬂat against the window frame and push each latch lever up until it locks. You should hear a click when each latch lever locks correctly. Lowering the Midgate with the Rear Glass in Place The midgate can be lowered to allow the cargo area of your vehicle to extend into the cab. The rear glass can be either installed in its normal position, or it can be removed and stored in the rear glass storage pocket. 2-18 Rear Glass in Normal Position 2. Standing outside of the vehicle, hold the midgate securely so it does not fall forward. Turn the midgate handle clockwise and pull the midgate toward you. Lowering the Midgate with the Rear Glass in the Storage Pocket 3. Lower the midgate until it is ﬂat. Rear Glass Stored in Glass Storage Pocket 2-19 Raising the Midgate To return the midgate to its normal position, raise the midgate up with a ﬁrm swinging motion until it latches into place securely. This will help to ensure that the midgate closes with enough force to engage the latches. If the rear glass is removed and you would like to put it back, do so using the instructions given previously. Tailgate Use the ignition/door key to unlock/lock the tailgate. Open the tailgate by lifting up on its handle while pulling the tailgate toward you. To shut the tailgate, ﬁrmly push it upward until it latches. Push and pull on the tailgate to be sure it is latched securely. Midgate Lowered with Crossbar Attached This procedure works the same as the procedure described previously, but when you lower the midgate with the rear glass in the stored position, you will notice that the entire crossbar will lower with the midgate. This is completely normal; however, since the crossbar lowers with the midgate, it will be heavier. As you lower the midgate be ready for the extra weight and do not let the midgate fall as you lower it. 2-20 Tailgate Removal The tailgate can be removed to allow for different loading situations. Although the tailgate can be removed without assistance, you may want someone to assist you with the removal to avoid possible damage to the vehicle. To remove the tailgate, do the following: 1. Hold the tailgate up, slightly raised. 2. Release the retaining cable clip by lifting the cable so it is level with the ground and then push the cable clip toward the vehicle. 3. Raise the tailgate at a slight upward angle, pull back on the tailgate at the right edge so it releases from the block hinge and then move the tailgate to the right to release the left edge. Reverse the above procedure to reinstall. Make sure the tailgate is secure. 2-21 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. 2-22 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 while Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 2-27. 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 and front passenger windows also have an express-down feature that allows the windows to be lowered without holding the switch. Press down fully on the window switch, then release, to activate the express-down mode. This mode can be canceled at any time by pulling up on the switch. To open the window partway, press the switch to the ﬁrst position until the window is at the desired position. Window Lockout o (Window Lockout): 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. 2-23 Sun Visors Sun Visors with Slide Rod Your vehicle may have this feature. Pull the sun visor down to block glare. Detach the sun visor from the center mount and slide it along the rod from side-to-side to cover the driver or passenger side of the front window. Swing the sun visor to the side to cover the side window. It can be moved along the rod from side-to-side in this position also. Sun Visors with Fixed Rod and Pull-out Extension Your vehicle may have this feature. Pull the sun visor down to block glare. Pull the sun visor extender out for additional coverage. Detach the sun visor from the center mount and swing it to the side to cover the side window. Lighted Visor Vanity Mirror Your vehicle has lighted visor vanity mirrors on both the driver’s and passenger’s sun visors. Pull the sun visor down and lift the mirror cover to turn the lamps on. 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 has a content theft-deterrent alarm system. The security light is located on the instrument panel cluster. See Security Light on page 3-43 for additional information. To activate the theft-deterrent system, do the following: 1. Close all the doors. 2. Lock the door with the remote keyless entry transmitter. The security light should come on and ﬂash. If the lock button on the remote keyless entry transmitter is pressed, but a door is open, you may hear three chimes indicating delayed locking is enabled. 2-24 See Delayed Locking on page 2-9 for additional information. Close the door and the content theft-deterrent system will be activated. If a locked door is opened without using the remote keyless entry transmitter or OnStar, if equipped with an active subscription, the alarm will go off. Your vehicle’s lamps will ﬂash and the horn will sound for about two minutes, then will turn off to save the battery power. If this occurs, you can turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. If your vehicle has a Driver Information Center (DIC), you can customize your alarm warning. See DIC Vehicle Customization on page 3-60 for additional information. The horn may chirp for 10 seconds before the alarm goes off if the theft-deterrent system is activated using the remote keyless entry transmitter and the driver’s door is opened. If this occurs, you can turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. 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:127) Always unlock a door with the remote keyless entry transmitter. If you set off the alarm by accident, turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, activate the system by locking the doors with the remote keyless entry transmitter. 2. Wait for the security light to go out. 3. Unlock the door with the manual door lock and open the door. This should set off the alarm. 4. Turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. If the alarm does not sound when it should, but the vehicle’s headlamps ﬂash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Instrument Panel Fuse Block on page 5-112 and Underhood Fuse Block on page 5-115. If the alarm does not sound or the vehicle’s headlamps do not ﬂash, see your dealer for service. 2-25 (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 5-112. See your dealer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program on page 7-6. 2-26 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 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: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 4-62 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. 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 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 (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. 2-27 Starting the 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. 2-28 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. 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. Any resulting damage would not be covered by your vehicle’s warranty. Adjustable Throttle and Brake Pedal If your vehicle has this feature, you can change the position of the throttle and brake pedals. This feature is designed for shorter drivers, since the pedals cannot move farther away from the standard position, but can move closer to you for better pedal reach. This feature can be programmed to work with the memory function (if equipped) on your vehicle. See Memory Seat on page 2-90. The vehicle must be in PARK (P) for this feature to operate. The buttons used to adjust the pedals are located on the driver’s side door panel. 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. Press the button closest to you to move the pedals closer to you. Press the button farthest from you to move the pedals away from you. 2-29 To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is located on the driver’s side of the engine compartment, near the power steering ﬂuid reservoir. 3. Plug it into a normal, grounded 110-volt AC outlet. 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 {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. 2-30 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 2-39. If you are pulling a trailer, see Towing a Trailer on page 4-62. 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 2-39. 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 Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-44. 2-31 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). 2-32 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. Tow/Haul Mode Your vehicle is equipped with a tow/haul mode. The button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” under Towing a Trailer on page 4-62 for more information. 2-33 Four-Wheel Drive If your vehicle has four-wheel drive, you will see the buttons shown below. You can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. Notice: Driving on clean, dry pavement in Four-Wheel-Drive High or Four-Wheel-Drive Low for an extended period of time may cause premature wear on your vehicle’s powertrain. Do not drive on clean, dry pavement in Four-Wheel Drive High or Four-Wheel-Drive Low for extended periods of time. The transfer case buttons are located to the left of the instrument panel cluster. 2-34 The front axle locks and unlocks automatically when you shift the transfer case. Some delay for the axle to lock or unlock is normal. For information on StabiliTrak®, see StabiliTrak® System on page 4-9. Use these buttons to shift into and out of four-wheel drive. You can choose among four driving settings: AUTO 4WD (Automatic Four-Wheel Drive): This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent only to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four-wheel drive. Driving in this mode results in slightly lower fuel economy than Two-Wheel High. 2 m (Two-Wheel High): This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4 m (Four-Wheel High): Use the four-wheel high position when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4 n (Four-Wheel Low): This setting also engages your front axle and delivers extra torque. You may never need this setting. It sends maximum power to all four wheels. You might choose Four Wheel-Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. StabiliTrak® will not engage in this mode. See StabiliTrak® System on page 4-9 for more information. {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 2-38. NEUTRAL (N): Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-57 or Towing Your Vehicle on page 4-57 for more information. Indicator lights in the button show which setting you are in. The indicator lights will come on brieﬂy when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will ﬂash while shifting the transfer case. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. If the SERVICE 4WD message stays on, you should take your vehicle to your dealer for service. See “Service 4WD message” under DIC Warnings and Messages on page 3-50. Shifting Into Four-Wheel High or AUTO 4WD (Automatic Four-Wheel Drive) Press and release the Four-Wheel High or AUTO 4WD button. This can be done at any speed, except when shifting from Four-Wheel Low, and the indicator light will ﬂash while shifting. It will remain on when the shift is completed.

This can be done at any speed, except when shifting from Four-Wheel Low. 2-35 Shifting Out of Four-Wheel Low To shift from Four-Wheel Low to Four-Wheel High, AUTO 4WD or Two-Wheel High, 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 is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the Four-Wheel High, AUTO 4WD or Two-Wheel High button. You must wait for the Four-Wheel High, AUTO 4WD or Two-Wheel High indicator light to stop ﬂashing and remain on before shifting your transmission into gear. Notice: Shifting the transmission into gear before the Four-Wheel Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Low indicator light to stop ﬂashing before shifting the transmission into gear. It is typical for your vehicle to exhibit signiﬁcant engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High ranges or from NEUTRAL with the engine running. Shifting Into Four-Wheel Low To shift to the Four-Wheel Low position, 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). Press and release the Four-Wheel Low button. You must wait for the four-wheel low indicator light to stop ﬂashing and remain on before shifting your transmission in gear. Notice: Shifting the transmission into gear before the Four-Wheel Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Low indicator light to stop ﬂashing before shifting the transmission into gear. It is typical for your vehicle to exhibit signiﬁcant engagement noise and bump when shifting between Four-Wheel Low and Four-Wheel High ranges or from NEUTRAL with the engine running. If the Four-Wheel Low button is pressed when your vehicle is in gear and/or moving, the Four-Wheel Low indicator light will ﬂash for 30 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 30 seconds the transfer case will shift to Four-Wheel High mode. 2-36 If the Four-Wheel High, AUTO 4WD or Two-Wheel High switch is pressed when your vehicle is in gear and/or moving, the Four-Wheel High, AUTO 4WD or Two-Wheel High 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). 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. See Parking Brake on page 2-38 for more information. 3. Start the vehicle or turn the ignition to RUN. 4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to Two-Wheel High. 6. Simultaneously press and hold the Two-Wheel High and Four-Wheel Low buttons for 10 seconds. The NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 7. If the engine is running, verify that the transmission 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 ACCESSORY, which will turn the engine off. 9. Place the transmission shift lever in PARK (P). 10. Turn the ignition to LOCK. 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.

After the transfer case has shifted out of NEUTRAL the NEUTRAL light will go out. 2-37 4. Release the parking brake. Notice: Shifting the transmission into gear before the Four-Wheel Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Low indicator light to stop ﬂashing before shifting the transmission into gear. 5. Start the engine and shift the transmission to the desired position. Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes. 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. 2-38 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 4-62. 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. With CAUTION: (Continued) CAUTION: (Continued) four-wheel drive, if your transfer case is in NEUTRAL, your vehicle will be free 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. If you are pulling a trailer, see Towing a Trailer on page 4-62. 1. Hold the brake pedal down with your right foot and set the parking brake. 2. Move the shift lever into the PARK (P) position by pulling the shift lever toward you and moving it up as far as it will go. 3. Be sure the transfer case is in a drive gear — not in NEUTRAL (N). 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). 2-39 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. If you have four-wheel drive and your transfer case is in NEUTRAL, your vehicle will be free 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. 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 unless you have to. 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). 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 2-39. 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). 2-40 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 2-30. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want. If you ever hold the brake pedal down but still cannot shift out of PARK (P), try this: 1. Turn the key to ACCESSORY. There is no shift interlock in this key position. 2. Apply and hold the brake until the end of Step 4. 3. Shift the vehicle to NEUTRAL (N). 4. Start the vehicle and then shift to the drive gear you want. 5. Have the system ﬁxed as soon as possible. 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. 2-41 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: 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 2-42. 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 4-40. 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. (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. 2-42 {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: Four-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.

Universal Home Remote System The Universal Home Remote System, a combined universal transmitter and receiver, provides a way to replace up to three hand-held transmitters used to activate devices such as gate operators, garage door openers, entry door locks, security systems, and home lighting. 2-58 Universal Home Remote System Operation Do not use the Universal Home Remote 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 Universal Home Remote Transmitter. Read the instructions completely before attempting to program the Universal Home Remote. Because of the steps involved, it may be helpful to have another person available to assist you in the programming steps. Keep the original hand-held transmitter for use in other vehicles as well as for future Universal Home Remote programming. It is also recommended that upon the sale of the vehicle, the programmed Universal Home Remote buttons should be erased for security purposes. See “Erasing Universal Home Remote Buttons” later in this section or, for assistance, see Customer Assistance Offices on page 7-4. 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 signal. Programming Universal Home Remote Follow these steps to program up to three channels: 1. Press and hold down the two outside Universal Home Remote buttons, releasing only when the Universal Home Remote 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 hand-held transmitter to the remaining two Universal Home Remote buttons. 2. Position the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the Universal Home Remote buttons while keeping the indicator light in view. 2-59 3. Simultaneously press and hold both the desired Universal Home Remote button 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 Universal Home Remote successfully receives the frequency signal from the hand-held transmitter. Release both buttons. 5. Press and hold the newly-trained Universal Home Remote button and observe the indicator light. If the indicator light stays on constantly, programming is complete and your device should activate when the Universal Home Remote button is pressed and released. To program the remaining two Universal Home Remote buttons, begin with Step 2 under “Programming Universal Home Remote.” 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. 2-60 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 Universal Home Remote 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. The Universal Home Remote should now activate your rolling-code equipped device. To program the remaining two Universal Home Remote buttons, begin with Step 2 of “Programming Universal Home Remote.” You do not want to repeat Step 1, as this will erase all previous programming from the Universal Home Remote buttons. 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 Universal Home Remote 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 or garage door opener by using the “Programming Universal Home Remote” procedures, regardless of where you live, replace Step 3 under “Programming Universal Home Remote” with the following: Continue to press and hold the Universal Home Remote button while you press and release every two seconds (cycle) the hand-held transmitter button until the frequency signal has been successfully accepted by the Universal Home Remote. The Universal Home Remote indicator light will ﬂash slowly at ﬁrst and then rapidly. Proceed with Step 4 under “Programming Universal Home Remote” to complete. Using Universal Home Remote Press and hold the appropriate Universal Home Remote button for at least half of a second. The indicator light will come on while the signal is being transmitted. Erasing Universal Home Remote Buttons To erase programming from the three Universal Home Remote 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. The Universal Home Remote is now in the train (learning) mode and can be programmed at any time beginning with Step 2 under “Programming Universal Home Remote” shown earlier in this section. Individual buttons cannot be erased, but they can be reprogrammed. See “Reprogramming a Single Universal Home Remote Button” following this section. 2-61 Cupholder(s) Your vehicle may be equipped with cupholders for the front and rear passengers.
