four hours before starting. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above 0°F (−18°C). To Use the Engine Coolant Heater 1. Turn off the engine. 2. 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 the cord into a normal, grounded 110-volt AC outlet. { CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a ﬁre. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you do not, it could be damaged. The length of time the heater should remain plugged in depends on several factors. Ask a dealer/retailer in the area where you will be parking the vehicle for the best advice on this. Active Fuel Management™ Vehicles with V8 engines may have Active Fuel Management™. This system allows the engine to operate on either all or half of its cylinders, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will operate in the half cylinder mode, allowing the vehicle to achieve better fuel economy. When greater power demands are required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation. If your vehicle has an Active Fuel Management™ indicator, see DIC Operation and Displays (With DIC Buttons) on page 3-52 or DIC Operation and Displays (Without DIC Buttons) on page 3-58 for more information on using this display. 2-31 Automatic Transmission Operation If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. If the vehicle is has an automatic transmission, it has an electronic shift position indicator within the instrument panel cluster. This display comes on when the ignition key is turned to the ON/RUN position. There are several different positions for the shift lever. Hydra-Matic® 4-Speed Automatic Transmission 2-32 Hevay Duty 6-Speed Automatic Transmission Shown (Light Duty Similar) See “Range Selection Mode” later in this section. P (Park): This position locks the rear wheels. It is the best position to use when starting the engine because the vehicle cannot move easily. When parked on a hill, especially when the vehicle has a heavy load, you might notice an increase in the effort to shift out of P (Park). See Torque Lock (Automatic Transmission) under Shifting Into Park on page 2-47 for more information. { CAUTION: { CAUTION: It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake ﬁrmly set. The vehicle can roll. Do not leave the 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 the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 2-47. If you are pulling a trailer, see Towing a Trailer on page 4-50. If you have Four-Wheel Drive, the vehicle will be free to roll — even if the shift lever is in P (Park) — if the transfer case is in Neutral. So, be sure the transfer case is in a drive gear, Two-Wheel Drive High or Four-Wheel Drive High or Four-Wheel Drive Low — not in Neutral. See Shifting Into Park on page 2-47. R (Reverse): Use this gear to back up. Notice: Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-31. 2-33 N (Neutral): In this position, the engine does not connect with the wheels. To restart the engine when the vehicle is already moving, use N (Neutral) only. Also, use N (Neutral) when the vehicle is being towed. { CAUTION: Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is ﬁrmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed. Notice: Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, and you are: (cid:129) Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. (cid:129) Going about 35 mph (55 km/h) or more, push the accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has more power. D (Drive) can be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. You might want to shift the transmission to a lower gear selection if the transmission shifts too often. Downshifting the transmission in slippery road conditions could result in skidding. See Skidding under Loss of Control on page 4-11. 2-34 The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing things such as vehicle speed, throttle position, and vehicle load. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the transmission does not upshift and instead holds the current gear. In some cases, this could appear to be a delayed shift, however the transmission is operating normally. The vehicle’s transmission uses adaptive shift controls. Adaptive shift controls continually compares key shift parameters to pre-programmed ideal shifts stored in the transmissions computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with a heavy load or when the temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings. When temperatures are very cold, the Hydra-Matic® 6-Speed transmission’s gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable with a cold transmission. This difference in shifting is normal. M (Manual Mode): This position is available on vehicles with the Hydra-Matic® 6-Speed transmission. It lets drivers select the range of gears appropriate for current driving conditions. If the vehicle has this feature, see Range Select Mode (Hydra-Matic® 6-Speed transmission) later in this section. 3 (Third): This position is also used for normal driving. It reduces vehicle speed more than D (Drive) without using the brakes. You might choose 3 (Third) instead of D (Drive) when driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears and when going down a steep hill. 2 (Second): This position reduces vehicle speed even more than 3 (Third) without using the brakes. You can use 2 (Second) on hills. It can help control vehicle speed as you go down steep mountain roads, but then you would also want to use the brakes off and on. If you manually select 2 (Second) in an automatic transmission, the transmission will start in second gear. You can use this feature for reducing the speed of the rear wheels when you are trying to start the vehicle from a stop on slippery road surfaces. 2-35 1 (First): For the Hydra-Matic® 4-Speed transmission this position reduces vehicle speed even more than 2 (Second) without using the brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in 1 (First) while the vehicle is moving forward, the transmission does not shift into ﬁrst gear until the vehicle is going slowly enough. For a Hydra-Matic® 6-Speed transmission, this position reduces vehicle speed without using the brakes. You can use it for major/severe downgrades and off-road driving where the vehicle would otherwise accelerate due to steepness of grade. When you shift to 1 (First) it provides the lowest gear appropriate to the vehicle’s current road speed and continues to downshift as the vehicle slows, eventually downshifting to 1 (First) gear. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. 2-36 Range Selection Mode (Hydra-Matic® 6-Speed Transmission) Base trim shown (uplevel similar) The vehicle may have a Range Selection Mode. The Range Selection Mode helps control the vehicle’s transmission and vehicle speed while driving down hill or towing a trailer by letting you select a desired range of gears. To use this feature, do the following: 1. Move the shift lever to M (Manual Mode). 2. Press the plus/minus buttons, located on the steering column shift lever, to select the desired range of gears for the current driving conditions. When M (Manual Mode) is selected a number displays next to the M, indicating the current gear. This number is the highest gear that can be used. However, the vehicle can automatically shift to lower gears as it adjusts to driving conditions. This means that all gears below that number are available. When 5 (Fifth) is selected, 1 (First) through 5 (Fifth) gears are automatically shifted by the vehicle, but 6 (Sixth) cannot be used until the plus/minus button located on the steering column lever is used to change to the gear. Grade Braking is not available when Range Selection Mode is active. See Tow/Haul Mode on page 2-38. While using Range Selection Mode, cruise control and the Tow/Haul mode can be used. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. Low Traction Mode If the vehicle has the Hydra-Matic® 6-Speed Automatic Transmission, it has a Low Traction Mode that assists in vehicle acceleration when road conditions are slippery, such as with ice or snow. While the vehicle is at a stop, select the second gear range using Range Selection Mode. This will limit torque to the wheels after it detects wheel slip, preventing the tires from spinning. 2-37 Tow/Haul Mode When Tow/Haul mode is selected the Tow/Haul indicator light will come on. The Tow/Haul mode works with the Autoride® feature, if the vehicle has this, to enhance the ride when trailering or with a loaded vehicle. See Autoride® on page 4-50. The vehicle has a Tow/Haul mode. The selector 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 or if there is a need to charge a battery installed in a trailer. See Towing a Trailer on page 4-50 for more information. 2-38 Grade Braking (Hydra-Matic® 6-Speed Automatic Transmission) The Grade Braking shift modes can be activated by pressing the button on the end of the shift control lever. While in Range Selection Mode, Grade Braking is deactivated allowing the driver to select a desired range of gears. Grade Braking is only active while the Tow/Haul Mode is selected and you are not in the Range Selection Mode. See “Tow/Haul Mode listed previously and Automatic Transmission Operation on page 2-32 for more information on the Range Selection Mode. Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by automatically implementing a shift schedule that utilizes the engine and transmission to slow the vehicle. This reduces wear on the braking system and increases control of the vehicle. Grade Braking monitors vehicle speed, acceleration, engine torque and brake pedal usage. Using this information, it detects when the truck is on a downhill grade and the driver desires to slow the vehicle by pressing the brake. Also see Towing a Trailer on page 4-50 for more information. Cruise Grade Braking (Hydra-Matic® 6-Speed Automatic Transmission) Cruise Grade Braking assists when driving on a downhill grade. It maintains vehicle speed by automatically implementing a shift schedule that uses the engine and the transmission to slow the vehicle. Cruise Grade Braking operates while Cruise Control is engaged in Tow/Haul mode to assist in maintaining vehicle speed under loaded vehicle conditions. It utilizes vehicle acceleration and deviation from desired speed to determine the correct gear for the operating condition. If vehicle speed is above the desired speed the transmission will downshift to slow the vehicle. If vehicle speed is near or below desired speed the trans will upshift, allowing vehicle speed to increase. While in the Range Select Mode (RSM) mode, Cruise Grade Braking is not available. See Automatic Transmission Operation on page 2-32. 2-39 Four-Wheel Drive If the vehicle has four-wheel drive, you can send the engine’s driving power to all four wheels for extra traction. Read the following 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. While driving on clean dry pavement and during tight turns, you may experience a vibration in the steering system. The vehicle has StabiliTrak®. Shifting into Four-Wheel-Drive Low will turn Traction Control and StabiliTrak® off. See StabiliTrak® System on page 4-6. Front Axle The front axle engages and disengages automatically when you shift the transfer case. Some delay for the axle to engage or disengage is normal. 2-40 Automatic Transfer Case The transfer case knob is located to the left of the instrument panel cluster. Use this dial to shift into and out of four-wheel drive. You can choose among ﬁve driving settings: 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 the vehicle to your dealer/retailer for service. An indicator light will ﬂash while shifting. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. 2 m (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. AUTO (Automatic Four-Wheel Drive): This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO, the front axle is engaged, but the vehicle’s power is primarily sent to the rear wheels. When the vehicle’s software determines a need for more traction, the system will transfer more power to the front wheels. Driving in this mode results in slightly lower fuel economy than Two-Wheel Drive High. 4 m (Four-Wheel Drive 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 the vehicle. This is the best setting to use when plowing snow. 4 n (Four-Wheel Drive Low): This setting also engages the 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 Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. The vehicle has StabiliTrak®. Shifting into Four-Wheel-Drive Low will turn Traction Control and StabiliTrak® off. See StabiliTrak® System on page 4-6. { CAUTION: Shifting the transfer case to N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in N (Neutral). See Parking Brake on page 2-45. N (Neutral): Shift the vehicle’s transfer case to N (Neutral) only when towing the vehicle. See Recreational Vehicle Towing on page 4-43 or Towing Your Vehicle on page 4-43 for more information. If the SERVICE 4 WHEEL DRIVE message stays on, you should take the vehicle to your dealer/retailer for service. See “SERVICE 4 WHEEL DRIVE message” under DIC Warnings and Messages on page 3-64. 2-41 You must wait for the Four-Wheel Drive Low indicator light to stop ﬂashing and remain on before shifting the transmission into gear. Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging the vehicle, always wait for the Four-Wheel Drive Low indicator light to stop ﬂashing before shifting the transmission into gear. The vehicle may have signiﬁcant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from N (Neutral) while the engine is running. If the knob is turned to the Four-Wheel Drive Low position when the vehicle is in gear and/or moving, the Four-Wheel Drive Low indicator light will ﬂash for 30 seconds and not complete the shift unless the vehicle is moving less than 3 mph (5 km/h) and the transmission is in N (Neutral). After 30 seconds the transfer case will shift to Four-Wheel Drive High mode. Shifting Into Four-Wheel Drive High or AUTO (Automatic Four-Wheel Drive) Turn the knob to the Four-Wheel High or AUTO position. This can be done at any speed, except when shifting from Four-Wheel Drive Low. The indicator light will ﬂash while shifting. It will remain on when the shift is completed. Shifting Into Two-Wheel Drive High Turn the knob to the Two-Wheel High position. This can be done at any speed, except when shifting from Four-Wheel Drive Low. See shifting out of Four-Wheel Drive Low later in this section for more information. Shifting Into Four-Wheel Drive Low When Four-Wheel Low is engaged, vehicle speed should be kept below 45 mph (72 km/h). Extended high-speed operation in 4L may damage or shorten the life of the drivetrain. To shift to the Four-Wheel Drive Low position, the ignition must be in ON/RUN and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in N (Neutral). The preferred method for shifting into Four-Wheel Drive Low is to have the vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel Drive Low position. 2-42 Shifting Out of Four-Wheel Drive Low To shift from Four-Wheel Drive Low to Four-Wheel Drive High, AUTO, or Two-Wheel Drive High, the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in N (Neutral) and the ignition in ON/RUN. The preferred method for shifting out of Four-Wheel Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn the knob to the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High position. You must wait for the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High indicator light to stop ﬂashing and remain on before shifting the transmission into gear. Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging the vehicle, always wait for the Four-Wheel Drive Low indicator light to stop ﬂashing before shifting the transmission into gear. The vehicle may have signiﬁcant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from N (Neutral) while the engine is running. If the knob is turned to the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High switch position when the vehicle is in gear and/or moving, the Four-Wheel Drive High, AUTO or Two-Wheel Drive High indicator light will ﬂash for 30 seconds but will not complete the shift unless the vehicle is moving less than 3 mph (5 km/h) and the transmission is in N (Neutral). Shifting into Neutral To shift the transfer case to N (Neutral) do the following: 1. Make sure the vehicle is parked so that it will not roll. 2. Set the parking brake and apply the regular brake pedal. See Parking Brake on page 2-45 for more information. 3. Start the vehicle or turn the ignition to ON/RUN. 4. Put the transmission in N (Neutral). 5. Shift the transfer case to Two-Wheel Drive High. 6. Turn the transfer case dial clockwise to N (Neutral) until it stops and hold it there until the N (Neutral) light starts blinking. This will take at least 10 seconds. Then slowly release the dial to the Four-Wheel Drive Low position. The N (Neutral) light will come on when the transfer case shift to N (Neutral) is complete. 2-43 7. If the engine is running, verify that the transfer case is in N (Neutral) by shifting the transmission to R (Reverse) for one second, then shift the transmission to D (Drive) for one second. 8. Turn the ignition to ACC/ACCESSORY, which will turn the engine off. 9. Place the transmission shift lever in P (Park). 10. Release the parking brake prior to moving the vehicle. 11. Turn the ignition to LOCK/OFF. Shifting Out of Neutral To shift out of N Neutral do the following: 1. Set the parking brake and apply the regular brake pedal. 2. Turn the ignition to ON/RUN with the engine off, and shift the transmission to N (Neutral). 3. Turn the transfer case dial to the desired transfer case shift position (Two-Wheel Drive High, Four-Wheel Drive High, AUTO). After the transfer case has shifted out of N (Neutral), the N (Neutral) light will go out. 4. Release the parking brake prior to moving the vehicle. Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped ﬂashing could damage the transfer case. To help avoid damaging the vehicle, always wait for the Four-Wheel Drive 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. 2-44 Parking Brake For vehicles with a release handle, set the parking brake by holding the regular brake pedal down, then pushing down the parking brake pedal. If the ignition is on, the brake system warning light will come on. See Brake System Warning Light on page 3-40. A chime sounds and the warning light ﬂashes when the parking brake is applied and the vehicle is moving at least 5 mph (8 km/h). To release the parking brake, hold the regular brake pedal down. Then pull the bottom edge of the lever with the parking brake symbol, located above the parking brake pedal. If the ignition is on when the parking brake is released, the brake system warning light goes off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 4-50. 2-45 If the ignition is on, the brake system warning light will come on. See Brake System Warning Light on page 3-40. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. To release the parking brake, hold the regular brake pedal down, then push down momentarily on the parking brake pedal until you feel the pedal release. Slowly pull your foot up off the park brake pedal. If the parking brake is not released when you begin to drive, the brake system warning light will ﬂash and a chime will sound warning you that the parking brake is still on. If you are towing a trailer and are parking on a hill, see Towing a Trailer on page 4-50. For vehicles without a release handle, set the parking brake by holding the regular brake pedal down, then pushing down the parking brake pedal. 2-46 Shifting Into Park { CAUTION: It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake ﬁrmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow. With four-wheel drive, if the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So, be sure the transfer case is in a drive gear — not in N (Neutral). If you are pulling a trailer, see Towing a Trailer on page 4-50. 1. Hold the brake pedal down, then set the parking brake. See Parking Brake on page 2-45 for more information. 2. Move the shift lever into the P (Park) 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 N (Neutral). 4. Turn the ignition key to LOCK/OFF. 5. Remove the key and take it with you. If you can leave the vehicle with the ignition key in your hand, the vehicle is in P (Park). 2-47 Leaving the Vehicle With the Engine Running { CAUTION: It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake ﬁrmly set. If you have four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So be sure the transfer case is in a drive gear — not in N (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 the vehicle with the engine running unless you have to. If you have to leave the vehicle with the engine running, be sure your vehicle is in P (Park) and the parking brake is ﬁrmly set before you leave it. After you move the shift lever into P (Park), hold the regular brake pedal down. Then, see if you can move the shift lever away from P (Park) without ﬁrst pulling it toward you. If you can, it means that the shift lever was not fully locked into P (Park). Torque Lock If you are parking on a hill and you do not shift your transmission into P (Park) 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 P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To ﬁnd out how, see Shifting Into Park on page 2-47. When you are ready to drive, move the shift lever out of P (Park) 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, then you will be able to pull the shift lever out of P (Park). 2-48 Shifting Out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: (cid:129) Prevent ignition key removal unless the shift lever is in P (Park) with the shift lever button fully released, and (cid:129) Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN or ACC/ACCESSORY and the regular brake pedal is applied. The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery. If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting on page 5-44 for more information. To shift out of P (Park) use the following: 1. Apply the brake pedal. 2. Move the shift lever to the desired position. If you still are unable to shift out of P (Park): 1. Ease the pressure on the shift lever. 2. While holding down the brake pedal, press the shift lever all the way into P (Park). 3. Move the shift lever to the desired position. If you are still having a problem shifting, then have the vehicle serviced soon. Parking Over Things That Burn { CAUTION: Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. 2-49 CAUTION: (Continued) (cid:129) The vehicle’s exhaust system has been modiﬁed, damaged or improperly repaired. (cid:129) There are holes or openings in the vehicle body from damage or after-market modiﬁcations that are not completely sealed. If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle: (cid:129) Drive it only with the windows completely down. (cid:129) Have the vehicle repaired immediately. Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation. Engine Exhaust { CAUTION: Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if: (cid:129) The vehicle idles in areas with poor ventilation (parking garages, tunnels, deep snow that may block underbody airﬂow or tail pipes). (cid:129) The exhaust smells or sounds strange or (cid:129) The exhaust system leaks due to corrosion or different. damage. CAUTION: (Continued) 2-50 Running the Vehicle 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 a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation. For more information, see Engine Exhaust on page 2-50. { CAUTION: It can be dangerous to get out of the vehicle if the automatic transmission shift lever is not fully in P (Park) with the parking brake ﬁrmly set. CAUTION: (Continued) CAUTION: (Continued) The vehicle can roll. Do not leave the 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 the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). { CAUTION: Four-wheel drive vehicles with the transfer case in N (Neutral) will allow the vehicle to roll, even if the automatic transmission shift lever is in P (Park). So, be sure the transfer case is in a drive gear — not in N (Neutral). Always set the parking brake. Follow the proper steps to be sure the vehicle will not move. See Shifting Into Park on page 2-47. If pulling a trailer, see Towing a Trailer on page 4-50. 2-51 Automatic Dimming Mirror Operation Automatic dimming reduces the glare from the headlamps of the vehicle behind you. The dimming feature comes on and the indicator light illuminates each time the ignition is turned to start. Cleaning the Mirror Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water. Outside Manual Mirrors Adjust the outside mirror so that the side of the vehicle and the area behind are seen. Manually fold the mirrors inward to prevent damage when going through an automatic car wash. To fold, push the mirror toward the vehicle. Push the mirror outward, to return to its original position. Using hood-mounted air deﬂectors and add-on convex mirror attachments could decrease mirror performance.

Park Tilt Mirrors Vehicles with the memory package have a passenger and/or driver mirror that tilts to a preselected position when the vehicle is in R (Reverse). This feature lets the driver view the curb when parallel parking. The mirror(s) return to the original position when the vehicle is shifted out of R (Reverse), or the ignition is turned off. Turn this feature on or off through the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 3-74 for more information. Outside Convex Mirror { CAUTION: A convex mirror can make things, like other vehicles, look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on the right. Check the inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex shaped. A convex mirror’s surface is curved so more can be seen from the driver seat. 2-55 Object Detection Systems Ultrasonic Rear Parking Assist (URPA) For vehicles with the Ultrasonic Rear Parking Assist (URPA) system, it operates at speeds less than 5 mph (8 km/h), and assists the driver with parking and avoiding objects while in R (Reverse). The sensors on the rear bumper are used to detect the distance to an object up to 8 feet (2.5 m) behind the vehicle, and at least 10 inches (25.4 cm) off the ground. { CAUTION: CAUTION: (Continued) If you do not use proper care before and while backing; vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing, be sure to look for objects and check the vehicle’s mirrors. The display is located near the passenger side rear window and can be seen by looking over your right shoulder. The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect: (cid:129) objects that are below the bumper, underneath the vehicle, or if they are too close or far from the vehicle children, pedestrians, bicyclists, or pets. CAUTION: (Continued) 2-56 URPA uses three color-coded lights to provide distance and system information. (cid:129) How the System Works URPA comes on automatically when the shift lever is moved into R (Reverse). The rear display brieﬂy illuminates to indicate the system is working. URPA operates only at speeds less than 5 mph (8 km/h). If the vehicle is above this speed, the red light on the rear display will ﬂash. To be detected, objects must be at least 10 inches (25.4 cm) off the ground and below liftgate level. Objects must also be within 8 feet (2.5 m) from the rear bumper. This distance may be less during warmer or humid weather. A single beep will sound the ﬁrst time an object is detected between 40 inches (1 m) and 8 feet (2.5 m) away. Beeping will occur continuously when the vehicle is at 23 inches (0.6 m) or closer to an object. The following describes what will occur with the URPA display as the vehicle gets closer to a detected object: Description amber light amber/amber lights amber/amber/red lights and continuous beeping for ﬁve seconds amber/amber/red lights ﬂashing and continuous beeping for ﬁve seconds English 8 ft 40 in 23 in Metric 2.5 m 1.0 m 0.6 m 1 ft 0.3 m The system can be disabled by pressing the rear park aid disable button located next to the radio. The indicator light will come on and PARK ASSIST OFF displays on the Driver Information Center (DIC) to indicate that URPA is off, see DIC Warnings and Messages on page 3-64 for information about clearing the message. 2-57 When the System Does Not Seem to Work Properly If the URPA system will not activate due to a temporary condition, the message PARK ASSIST OFF will be displayed on the DIC and a red light will be shown on the rear URPA display when the shift lever is moved into R (Reverse). This occurs under the following conditions: The driver disables the system. The ultrasonic sensors are not clean. Keep the vehicle’s rear bumper free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle on page 5-110. (cid:129) A trailer was attached to the vehicle, or a bicycle or an object was hanging out of the liftgate during the last drive cycle, the red light may illuminate in the rear display. Once the attached object is removed, URPA will return to normal operation. (cid:129) A tow bar is attached to the vehicle. The vehicle’s bumper is damaged. Take the vehicle to your dealer/retailer to repair the system. (cid:129) Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck. If the system is still disabled, after driving forward at least 15 mph (25 km/h), take the vehicle to your dealer/retailer. 2-58 Side Blind Zone Alert (SBZA) The vehicle may have a Side Blind Zone Alert (SBZA) system. Read this entire section before using the system. The SBZA system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. This device complies with RSS-310 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. Frequency of operation: 24.05GHz – 24.25GHz Field Strength: Not greater than 2.5V/m peak (0.25V/m average) at a distance of 3m (cid:129) (cid:129) (cid:129) The manufacturer is not responsible for any radio or TV interference caused by unauthorized modiﬁcations to this equipment. Such modiﬁcations could void the user’s authority to operate the equipment. { CAUTION: When the system detects a vehicle in the side blind zone, amber SBZA displays light up in the side mirrors. This indicates that it may be unsafe to change lanes. Before making a lane change, always check the SBZA display, check the outside and rearview mirrors, look over your shoulder for vehicles and hazards, and use the turn signal. SBZA is only a lane changing aid and does not replace driver vision. SBZA does not detect: (cid:129) Vehicles outside the side blind zones which may be rapidly approaching. (cid:129) Pedestrians, bicyclists, or animals. Failure to use proper care when changing lanes may result in damage to the vehicle, injury, or death. Always check the outside and rearview mirrors, glance over your shoulder, and use the turn signal before changing lanes. 2-59 SBZA Detection Zones The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, 11 ft. or 3.5 m. This zone starts at each side mirror and goes back approximately 16 ft. (5.0 m). The height of the zone is approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off the ground. Use caution while changing lanes when towing a trailer, as the SBZA detection zones do not change when a trailer is towed. How the System Works Left Side Mirror Display Right Side Mirror Display When the vehicle is started, both outside mirror displays will brieﬂy come on to indicate that the system is operating. When the vehicle is moving forward, the left or right side mirror SBZA display will light up if a vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the SBZA display will ﬂash to give you extra warning not to change lanes. SBZA displays do not come on while the vehicle is approaching or passing other vehicles. At speeds greater then 20 mph (32 km/h), SBZA displays may come on when a vehicle you have passed remains in or drops back into the detection zone. 2-60 SBZA can be disabled through the Driver Information Center (DIC). See Driver Information Center (DIC) on page 3-51 for more information. If the SBZA is disabled by the driver, the SBZA mirror displays will not light up during normal driving. When the System Does Not Seem To Work Properly Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced due to an occasional missed alert. The number of missed alerts will increase with increased rainfall or road spray. If the SBZA displays do not light up when the system is on and vehicles are in the blind zone, the system may need service. Take the vehicle to your dealer/retailer. SBZA is designed to ignore stationary objects; however, the system may occasionally light up due to guard rails, signs, trees, shrubs, and other stationary objects. This is normal system operation, the vehicle does not need service. SBZA does not operate when the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, slush, or in heavy rainstorms. For cleaning instructions, see Washing Your Vehicle on page 5-110. If the DIC still displays the SIDE BLIND ZONE SYS. UNAVAILABLE message after cleaning the bumper, see your dealer/retailer. The SBZA displays may remain on if a trailer is attached to the vehicle, or a bicycle or object is extending out to either side of the vehicle. When SBZA is disabled for any reason other than the driver turning it off, the driver will not be able to turn SBZA back on using the DIC. The SIDE BLIND ZONE ALERT ON option will not be selectable if the conditions for normal system operation are not met. Until normal operating conditions for SBZA are met, you should not rely upon SBZA while driving. 2-61 SBZA Error Messages The following messages may appear in the DIC: SIDE BLIND ZONE ALERT SYSTEM OFF: This message indicates that the driver has turned the system off. SIDE BLIND ZONE SYS. UNAVAILABLE: This message indicates that the SBZA system is disabled either because the sensor is blocked and cannot detect vehicles in your blind zone, or the vehicle is passing through an open ﬁeld of view area, such as the desert, where there is insufficient data for operation. The sensor may be blocked by mud, dirt, snow, ice, slush, or even heavy rainstorms. This message may also activate during heavy rain or due to road spray. The vehicle does not need service. For cleaning, see Washing Your Vehicle on page 5-110. SERVICE SIDE BLIND ZONE ALERT SYSTEM: If this message appears, both SBZA displays will remain on indicating there is a problem with the SBZA system. If these displays remain on after continued driving, the system needs service. Take the vehicle to your dealer/retailer. 2-62 Rear Vision Camera (RVC) This vehicle may have a Rear Vision Camera system. Read this entire section before using it. { CAUTION: The Rear Vision Camera (RVC) system does not replace driver vision. RVC does not: (cid:129) Detect objects that are outside the camera’s ﬁeld of view, below the bumper, or underneath the vehicle. (cid:129) Detect children, pedestrians, bicyclists, or pets. Do not back the vehicle by only looking at the rear vision camera screen, or use the screen during longer, higher speed backing maneuvers or where there could be cross-traffic. Your judged distances using the screen will differ from actual distances. So if you do not use proper care before backing up, you could hit a vehicle, child, pedestrian, bicyclist, or pet, resulting in vehicle damage, injury, or death. Even though the vehicle has the RVC system, always check carefully before backing up by checking behind and around the vehicle. Vehicles Without Navigation System The rear vision camera system is designed to help the driver when backing up by displaying a view of the area behind the vehicle. When the key is in the ON/RUN position and the driver shifts the vehicle into R (Reverse), the video image automatically appears on the inside rear view mirror.

Ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. The back of the vehicle is in an accident, the position and mounting angle of the camera can change or the camera can be affected. Be sure to have the camera and its position and mounting angle checked at your dealer/retailer. There are extreme temperature changes. The rear vision camera system display in the rearview mirror may turn off or not appear as expected due to one of the following conditions. If this occurs the left indicator light on the mirror will ﬂash. (cid:129) A slow ﬂash may indicate a loss of video signal, or no video signal present during the reverse cycle. (cid:129) A fast ﬂash may indicate that the display has been on for the maximum allowable time during a reverse cycle, or the display has reached an Over Temperature limit. The fast ﬂash conditions are used to protect the video device from high temperature conditions. Once conditions return to normal the device will reset and the green indicator will stop ﬂashing. During any of these fault conditions, the display will be blank and the indicator will continue to ﬂash as long as the vehicle is in R (Reverse) or until the conditions return to normal. Pressing and holding z when the left indicator light is ﬂashing will turn off the video display along with the left indicator light. 2-67 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) OnStar service is provided subject to the OnStar Terms and Conditions included in the OnStar Subscriber glove box literature.

To program another Rolling Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1 through 5, choosing a different function button in Step 3 than what was used for the garage door opener. If these instructions do not work, the garage door opener is probably a Fixed Code unit. Follow the Programming instructions that follow for a Fixed Code garage door opener. Programming Universal Home Remote — Fixed Code For questions or help programming the Universal Home Remote System, call 1-866-572-2728 or go to learcar2u.com. Most garage door openers sold before 1996 are Fixed Code units. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before starting. Otherwise, the device will time out and the procedure will have to be repeated. 2-74 To program up to three devices: 1. To verify that the garage door opener is a Fixed Code unit, remove the battery cover on the hand held transmitter supplied by the manufacturer of the garage door opener motor. If there are a row of dip switches similar to the graphic above, the garage door opener is a Fixed Code unit. If you do not see a row of dip switches, return to the previous section for Programming Universal Home Remote – Rolling Code. Your hand held transmitter can have between eight to 12 dip switches depending on the brand of transmitter. The garage door opener receiver (motor head unit) could also have a row of dip switches that can be used when programming the Universal Home Remote. If the total number of switches on the motor head and hand held transmitter are different, or if the dip switch settings are different, use the dip switch settings on the motor head unit to program the Universal Home Remote. The motor head dip switch settings can also be used when the original hand held transmitter is not available. Example of Eight Dip Switches with Two Positions Example of Eight Dip Switches with Three Positions The panel of switches might not appear exactly as they do in the examples above, but they should be similar. The switch positions on the hand-held transmitter could be labeled, as follows: (cid:129) A switch in the up position could be labeled as “Up,” “+,” or “On.” (cid:129) A switch in the down position could be labeled as “Down,” “−,” or “Off.” (cid:129) A switch in the middle position could be labeled as “Middle,” “0,” or “Neutral.” 2-75 2. Write down the eight to 12 switch settings from left to right as follows: (cid:129) When a switch is in the up position, write “Left.” (cid:129) When a switch is in the down position, write “Right.” If a switch is set between the up and down position, write “Middle.” The switch settings written down in Step 2 now become the button strokes to be entered into the Universal Home Remote in Step 4.

Luggage Carrier Notice: Loading cargo on the luggage carrier that weighs more than 200 lbs (91 kg) or hangs over the rear or sides of the vehicle can damage the vehicle. Load cargo so that it rests on the slats as far forward as possible and against the side rails, making sure to fasten it securely. For vehicles with a luggage carrier, items can be loaded on top of the vehicle. The luggage carrier has siderails attached to the roof. It can also have crossrails which can be moved back and forth to help secure cargo. Tie the load to the siderails or siderail supports. Do not exceed the maximum vehicle capacity when loading the vehicle. For more information on vehicle capacity and loading, see Loading the Vehicle on page 4-33. Make sure the cargo is properly loaded. To prevent damage or loss of cargo while driving, periodically stop and check to make sure cargo is still securely fastened. If small heavy objects are placed on the roof, cut a piece of 3/8 inch plywood to ﬁt inside the crossrails and siderails to spread the load. Tie the plywood to the siderail supports. Tie the load and secure it to the crossrails or the siderail supports. Use the crossrails only to keep the load from sliding. To move a crossrail, lift the release lever up, on both sides of the rail. Then slide the crossrail to the desired position balancing the force side to side. Press the release lever down on both sides of the rail, down to tighten it. Try to slide the crossrail back and forth slightly to make sure it is tight. To carry long items, move the crossrails as far apart as possible. Tie the load to the crossrails and the siderails or siderail supports. Also tie the load to the bumpers, but do not tie the load so tightly that the crossrails or siderails are damaged. (cid:129) After moving a crossrail, be sure it is securely locked into the siderail. A Center High-Mounted Stoplamp (CHMSL) is located above the rear window glass. Make sure items loaded on the roof of the vehicle do not block or damage the CHMSL. 2-79 (cid:129) (cid:129) (cid:129) To use the cover, for vehicles that have it: 1.
