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 DIC Warnings and Messages on page 3-55 for further information. 2-43 Shifting into Four-Wheel High or AUTO 4WD (Automatic Four-Wheel Drive) Press and release the four-wheel high or AUTO 4WD switch. 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. Shifting into Two-Wheel High Press and release the Two-Wheel High switch. This can be done at any speed, except when shifting from Four-Wheel Low. Shifting into Four-Wheel Low Notice: Shifting the transfer case into Four-Wheel Low while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into Four-Wheel Low while the vehicle is moving faster than 3 mph (5 km/h). To shift to Four-Wheel Low, 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 switch. 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 (N) with the engine running. If the Four-Wheel Low switch 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. 2-44 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 switch. 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. The transfer case may make noise and the vehicle may jerk when the transfer case is shifted between Four-Wheel Low and Four-Wheel High ranges or from NEUTRAL with the engine running. 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 {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 2-52. 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. 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 red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 2-45 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. Electronic Transfer Case If your four-wheel-drive vehicle has the electronic transfer case, the transfer case switches are located to the left of the instrument panel cluster. 7. If the engine is running, shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles equipped with a manual transmission. 8. Turn the engine off, by turning the key to ACCESSORY. 9. Place the transmission shift lever in PARK (P). 10. Turn the ignition to LOCK. Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and apply the regular brake pedal. 2. Turn the ignition to RUN with the engine off. 3. Shift the transmission to NEUTRAL (N). 4. Press the button for the desired transfer case shift position (Two-Wheel High, Four-Wheel High, AUTO 4WD, or Four-Wheel Low). 5. After the transfer case has shifted out of NEUTRAL the red light will go out. 6. Release the parking brake. 7. You may start the engine and shift the transmission to the desired position. 2-46 Recommended Transfer Case Settings Transfer Case Settings 2 m 4 m 4 n N YES Driving Conditions Normal Severe Extreme YES YES Vehicle in Tow* YES *See Recreational Vehicle Towing on page 4-62 or Towing Your Vehicle on page 4-62 for further information. Use these switches to shift into and out of four-wheel drive. You can choose among three driving settings: 2 m (Two-Wheel High): This setting is for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. {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 2-52. (N) NEUTRAL: Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 4-62 or Towing Your Vehicle on page 4-62 for more information. 4 m (Four-Wheel High): This setting engages your front axle to help drive your vehicle. Use four-wheel high when you need extra traction, such as on snowy or icy roads, or in most off-road situations. 2-47 4 n (Four-Wheel Low): This setting also engages your front axle to give you extra traction. You may never need Four-Wheel Low. It sends the maximum power to all four wheels. You might choose Four-Wheel Low if you were driving off-road in sand, mud or deep snow and while climbing or descending steep hills. When operating in Four-Wheel Low, the gear ratio provides additional torque when compared to Four-Wheel High. The transmission gear shift feel will be exaggerated. Indicator lights in the switches show you which setting you are in. The indicator lights will come on brieﬂy when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take your vehicle in for service. An indicator light will ﬂash while shifting. Fast ﬂashing means the conditions were not met to make the desired shift, typically the vehicle was going too fast, the automatic transmission was not in neutral, or the clutch pedal was not fully pressed. Slow ﬂashing means the shift is in progress. It will stay on when the shift is completed. If for some reason the transfer cannot make a requested shift, it will return to the last chosen setting. Shifting from Two-Wheel High to Four-Wheel High Press and release the Four-Wheel High switch. This can be done at any speed, and the front axle will lock automatically with some delay. Shifting from Four-Wheel High to Two-Wheel High Press and release the Two-Wheel High switch. This can be done at any speed, and the front axle will unlock automatically with some delay. It is normal to hear and feel your vehicle’s transfer case shift into Four-Wheel Low. If you shift with the vehicle stopped, the indicator light may remain ﬂashing slowly. It may be necessary to shift the transmission momentarily into REVERSE (R) and DRIVE (D), for an automatic transmission, or REVERSE (R) and FIRST (1) for a manual transmission to have the light stop ﬂashing. 2-48 Shifting from Two-Wheel High or Four-Wheel High to Four-Wheel Low Notice: Shifting the transfer case into Four-Wheel Low while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into Four-Wheel Low while the vehicle is moving faster than 3 mph (5 km/h). To shift from Two-Wheel High or Four-Wheel High to Four-Wheel Low, the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) for an automatic transmission or the clutch pedal pressed for a manual transmission. The preferred method for shifting into four-wheel low is to have your vehicle moving 3 mph (5 km/h). Press and release the Four-Wheel Low switch. You must wait for the four-wheel low indicator light to stop ﬂashing and stay on before shifting your transmission into gear or releasing the clutch pedal. 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. If the Four-Wheel Low switch 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 slower than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). The transfer case will shift to Four-Wheel High while waiting to complete the shift. 2-49 Shifting from Four-Wheel Low to Four-Wheel High or Two-Wheel High To shift from four-wheel low to Four-Wheel High or Two-Wheel High, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) for an automatic transmission or the clutch pedal pressed for a manual transmission. The preferred method for shifting out of Four-Wheel Low is to have your vehicle moving 3 mph (5 km/h). Press and release the Two-Wheel High or Four-Wheel High switch. You must wait for the Two-Wheel High or Four-Wheel High indicator light to stop ﬂashing and remain on before shifting your transmission into gear or releasing the clutch pedal. If the Four-Wheel High switch is pressed when your vehicle is in gear and/or moving, the Four-Wheel High indicator light will ﬂash for 30 seconds but will not complete the shift unless the vehicle is moving slower than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). Shifting into NEUTRAL {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 2-52. To shift the transfer case to NEUTRAL, ﬁrst make sure the vehicle is parked so that it will not roll: 1. Set the parking brake. 2. Start the vehicle or turn the ignition to RUN. 3. Press the foot brake pedal and put the transmission in NEUTRAL (N). 2-50 4. Shift the transfer case to Two-Wheel High. 5. Simultaneously press and hold the Two-Wheel High and Four-Wheel Low buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 6. Start the engine if it is not already running. 7. Press and hold the foot brake pedal and Shift the transmission to REVERSE (R) for one second, then shift the transmission for one second to DRIVE (D) for an automatic transmission, or FIRST (1) for vehicles equipped with a manual transmission and then let out the clutch. This is to ensure the transfer case is in NEUTRAL. If not, repeat this procedure starting at Step 3. 8. Turn the engine off, by turning the key to ACCESSORY. 9. Place the transmission shift lever in PARK (P) for an automatic transmission, or FIRST (1) for vehicles equipped with a manual transmission. 10. Turn the ignition to LOCK. Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and press and hold the regular brake pedal. 2. Shift the transmission to NEUTRAL (N) for an automatic transmission, or press the clutch pedal for vehicles equipped with a manual transmission. Then turn the ignition to RUN with the engine off. 3. Press the button for the desired transfer case shift position (Two-Wheel High, Four-Wheel High, or Four-Wheel Low). 4. After the transfer case has shifted out of NEUTRAL the red light will go out. 5. Release the parking brake. 6. You may 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. 7. After the transfer case has shifted out of NEUTRAL the red light will go out. 2-51 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. 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 4-67. 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. 2-52 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. If your vehicle has four-wheel drive, 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). Shifting Into Park (P) (Automatic Transmission) {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 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 4-67. 2-53 Leaving Your Vehicle With the Engine Running (Automatic Transmission) {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 (Automatic Transmission) 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)” listed earlier in this section. 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). 2-54 Shifting Out of Park (P) (Automatic Transmission) Your vehicle has an automatic transmission shift lock control system which locks the shift lever in PARK (P) when the ignition is in the LOCK position. 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 2-26 and “Torque Lock” under Shifting Out of Park (P) (Automatic Transmission) on page 2-55. If your vehicle has an Allison Transmission®, the transmission is equipped with a park pawl designed to hold the higher weight of commercial medium duty trucks. Therefore, the Allison Transmission® uses larger parts than other automatic transmissions. These larger parts may sometimes make a clunk noise when the selector lever is moved from DRIVE (D) or REVERSE (R) to PARK (P). This is normal and there is no damage occurring during these shifts. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want. If you ever hold the brake pedal down but still can’t shift out of PARK (P), try this: 1. Turn the key to 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 transmission to NEUTRAL (N). 4. Start the vehicle and then shift to the gear you want. 5. Have the system ﬁxed as soon as you can. 2-55 Parking Your Vehicle (Manual Transmission) {CAUTION: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the manual transmission is in gear. Your 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 2-52 for more information. Before you get out of your vehicle, move the shift lever into REVERSE (R), and ﬁrmly apply the parking brake. Once the shift lever has been placed into REVERSE (R) with the clutch pedal pressed in, you can turn the ignition key to LOCK, press the key release button, remove the key and release the clutch. If you are parking on a hill, or if you are pulling a trailer, see Towing a Trailer on page 4-67. 2-56 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. CAUTION: (Continued) 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. 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. CAUTION: (Continued) 2-57 Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: It can be dangerous to get out of your vehicle if the automatic transmission 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 it is on fairly level ground, always set the parking brake and move the automatic transmission shift lever to PARK (P), or the manual transmission shift lever to NEUTRAL. {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 2-57. 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 4-42. 2-58 {CAUTION: Four-wheel drive vehicles with the transfer case in NEUTRAL will allow the vehicle to roll, even if your automatic transmission 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) (Automatic Transmission) on page 2-53. If you are pulling a trailer, see Towing a Trailer on page 4-67.

The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push in the COMP button for approximately eight seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. 2-66 (cid:127) (cid:127) Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings. To adjust for compass variance: 1. Find your current location and variance zone number on the following zone map. 2. Press and hold the COMP button for ﬁve seconds until a zone number appears in the display. 3. Press the COMP button on the bottom of the mirror until the new zone number appears in the display. After you stop pressing the button, the display will show a compass direction within a few seconds. 2-67 Outside Camper-Type Mirrors If your vehicle is equipped with this style camper-type mirrors, they can be adjusted so you can have a clear view of the objects behind you.

If your vehicle is equipped with the Universal Home Remote Transmitter, it complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device. Changes and modiﬁcations to this system by other than an authorized service facility could void authorization to use this equipment. 2-75 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. 2-76 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. 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. 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. 2-77 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.

Headlamp High/Low-Beam Changer 53(Headlamp High/Low Beam Changer): To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. As you signal a turn or a lane change, if the arrows ﬂash more quickly than normal, a signal bulb may be burned out and other drivers won’t see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check for burned-out bulbs and a blown fuse. See Fuses and Circuit Breakers on page 5-123. Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each ﬂash of the turn signal and the message TURN SIGNAL ON will also appear in the DIC. To turn the chime and message off, move the turn signal lever to the off position. 3-8 Flash-to-Pass This feature lets you use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If your headlamps are in the automatic position or on low beam, your high-beam headlamps will turn on. They’ll stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster will come on. Release the lever to return to normal operation. Windshield Wipers Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement on page 5-71 Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Clear away snow or ice to prevent an overload. You control the windshield wipers by turning the band with the wiper symbol on it. 8(Mist): For a single wiping cycle, turn the band to mist. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. N(Delay): You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. 6 (Low Speed): For steady wiping at low speed, turn the band away from you to the ﬁrst solid band past the delay settings. For high-speed wiping, turn the band further, to the second solid band past the delay settings. To stop the wipers, move the band to off. 1 (High Speed): For high-speed wiping, turn the band further, to the second solid band past the delay settings. 9(Off): To stop the wipers, move the band to off. 3-9 Windshield Washer Cruise Control LQ (Washer Fluid): There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer ﬂuid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed. {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. 3-10 9(Off): This position turns the system off. If your vehicle is equipped with an Allison® automatic transmission, see “Grade Braking and Cruise Grade Braking (Allison Transmission®) under Tow/Haul Mode on page 2-31 for an explanation of how cruise control interacts with the tap up/down gear selection, tow/haul and grade braking systems. R(On): This position activates the system. + (Resume/Accelerate): Push the lever to this symbol to make the vehicle accelerate or resume to a previously set speed. T(Set): Press this button to set the speed. With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). If you apply your brakes, the cruise control will shut off. {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. Setting Cruise Control {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Move the cruise control switch to on. 2. Get up to the speed you want. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. The cruise symbol on the instrument panel will illuminate when the cruise control is engaged. 3-11 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you don’t need to reset it. Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch brieﬂy from on to resume/accelerate. You’ll go right back up to your chosen speed and stay there. If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at resume/accelerate. Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: (cid:127) Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You’ll now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off. (cid:127) Move the cruise switch from on to resume/ accelerate. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch brieﬂy to resume/accelerate. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster. 3-12 Ending Cruise Control There are four ways to turn off the cruise control: (cid:127) Step lightly on the brake pedal, (cid:127) move the cruise control switch to off, or shift the transmission to NEUTRAL (N). If the accelerator pedal is held for 60 seconds or longer, cruise control will turn off. Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. Reducing Speed While Using Cruise Control (cid:127) Press in the button at the end of the lever until you reach the lower speed you want, then release it. To slow down in very small amounts, brieﬂy press the set button. Each time you do this, you’ll go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier. Using Cruise Control on Hills How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers ﬁnd this to be too much trouble and don’t use cruise control on steep hills. 3-13 (cid:127) (cid:127) (cid:127) Headlamps The control on the driver’s side of your instrument panel operates the headlamps. Turn the control clockwise to operate the lamps. The headlamp control has four positions: 9 (Off): Turning the control to this position turns off the Daytime Running Lamps (DRL) and the automatic headlamps. AUTO (Automatic): Turning the control to this position puts the system into automatic headlamp mode. 3-14 ; (Parking Lamps): Turning the control to this position turns on the parking lamps, together with the following: (cid:127) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights (cid:127) Roof Marker Lamps (If Equipped) 5 (Headlamps): Turning the control to this position turns on the headlamps, together with the previously listed lamps and lights. You can switch your headlamps from high to low-beam by pushing the turn signal/high-beam lever towards the instrument panel. A circuit breaker protects your headlamps. If you have an electrical overload, your headlamps will ﬂicker on and off. Have your headlamp wiring checked right away if this happens. Headlamps on Reminder A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is off, in LOCK, ACCESSORY, or a door is open. To disable the chime, turn the light off then back on. (cid:127) (cid:127) (cid:127) Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system will come on when the following conditions are met: The ignition is on The exterior lamps control is in AUTO The automatic transmission is not in PARK (P) The light sensor determines it is daytime When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker and other lamps won’t be on. The instrument panel won’t be lit up either. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. When you turn the headlamp switch off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside. Shifting the transmission into PARK (P) will allow you to idle the vehicle with the DRL off. The DRL will stay off until you shift the transmission out of PARK (P). This procedure applies only to vehicles ﬁrst sold in the United States. Automatic Headlamp System When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. To turn off the automatic headlamp system, turn the exterior lamps switch to the off position and then release. Turning off the automatic headlamp system with the headlamp switch is not available for vehicles ﬁrst sold in Canada. For vehicles ﬁrst sold in Canada, you can turn off the automatic headlamp system when parked at night by applying the parking brake before starting your vehicle. The headlamps will remain off once the vehicle is started for as long as you are parked. If you release the parking brake, the lights will turn on. If the parking brake is not released before you begin to drive, the exterior lamps will turn on above 2 mph (3.2 km/h). 3-15 (cid:127) (cid:127) (cid:127) (cid:127) To idle your vehicle with the automatic headlamp system off, turn the control to the off position. You may be able to turn off your Automatic Headlamp System. See Daytime Running Lamps (DRL) on page 3-15 for more information. Your headlamps will also stay on after you exit the vehicle. You can program this feature using the Driver Information Center (DIC). See DIC Vehicle Customization on page 3-64. As with any vehicle, you should turn on the regular headlamp system when you need them. Your vehicle is equipped with a light sensor located on the top of the instrument panel in the defroster grille. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-18. 3-16 Fog Lamps If your vehicle has fog lamps, use them for better vision in foggy or misty conditions. The fog lamp button is located on the left side of the instrument panel. Your parking lamps and/or low-beam headlamps must be on for your fog lamps to work. Press the button to turn the fog lamps on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use your fog lamps in the dark without turning on your headlamps. The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. The fog lamps will be cancelled after the ignition is turned off. If you still want to use the fog lamps after you restart the vehicle, you will need to press the fog lamp button again. Some localities have laws that require the headlamps to be on along with the fog lamps. 3-17 Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the headlamp control. Turn the thumbwheel up to adjust the instrument panel lights. Turn the thumbwheel up to return the radio display to full brightness when the headlamps or parking lamps are on. To turn on the dome lamps, turn the thumbwheel all the way up. Dome Lamps The dome lamps will come on when you open a door. You can also turn the dome lamps on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the dome lamps will remain on whether a door is opened or closed. Auxiliary Roof Mounted Lamp If your vehicle has this feature, this button includes wiring provisions for a dealer or a qualiﬁed service center to install an auxiliary roof lamp. This button is located on the center of the instrument panel near the climate controls. When the wiring is connected to an auxiliary roof mounted lamp, pressing the button will activate the lamp and illuminate an indicator light near the button. Pressing the button again will turn off the roof mounted lamp. If your vehicle has this button, your vehicle may have the snow plow prep package. For further information see Adding a Snow Plow or Similar Equipment on page 4-54. 3-18 Dome Lamp Override E (Dome Lamp Override): You can use the dome override button, located below the exterior lamps control, to set the dome lamps to come on automatically when a door is opened, or to remain off. To turn the lamps off, press the button into the in position. With the button in this position, the dome lamps will remain off when the doors are open. To return the lamps to automatic operation, press the button again and return it to the out position. With the button in this position, the dome lamps will come on when you open a door. Entry Lighting Your vehicle is equipped with an illuminated entry feature. When the doors are opened, the dome lamps will come on if the dome override button is in the out position. If the dome override button is pressed in, the lamps will not come on. Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. The lights will not come on if the dome override button is pressed in.
