If you lose or damage a PASS-Key® III+ key, see your dealer/retailer or a locksmith who can service PASS-Key® III+ to have a new key made. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. 3-21 Starting and Operating Your Vehicle New Vehicle Break-In Notice: The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: (cid:129) Keep your speed at 55 mph (88 km/h) or less for the ﬁrst 500 miles (805 km). (cid:129) Do not drive at any one constant speed, fast or slow, for the ﬁrst 500 miles (805 km). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle. (cid:129) Avoid making hard stops for the ﬁrst 200 miles (322 km) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. (cid:129) Do not tow a trailer during break-in. See Towing a Trailer on page 5-26 for the trailer towing capabilities of the vehicle and more information. Following break-in, engine speed and load can be gradually increased. 3-22 Ignition Positions The ignition switch has four different positions. To shift out of P (Park), the ignition must be in ON/RUN and the regular brake pedal applied. A (LOCK/OFF): This position locks the ignition and transmission. You will only be able to remove the key when the ignition is turned to LOCK/OFF. Notice: Using a tool to force the key to turn in the ignition could cause damage to the switch or break the key. Use the correct key, make sure it is all the way in, and turn it only with your hand. If the key cannot be turned by hand, see your dealer/retailer. B (ACC/ACCESSORY): This is the position in which you can operate things like the radio and the windshield wipers when the engine is off. C (ON/RUN): This position can be used to operate the electrical accessories and to display some instrument panel cluster warning and indicator lights. The switch stays in this position when the engine is running. If you leave the key in the ACC/ACCESSORY or ON/RUN position with the engine off, the battery could be drained. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. D (START): This is the position that starts the engine. When the engine starts, release the key. The ignition switch returns to ON/RUN for driving. A warning tone will sound when the driver door is opened, the ignition is in ACC/ACCESSORY or LOCK/OFF and the key is in the ignition. Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: • Audio System • Power Windows (if equipped) These features will work when the ignition key is in ON/RUN or ACC/ACCESSORY. Once the key is turned from ON/RUN to LOCK/OFF, power to the radio will continue to work 10 minutes or until the driver door is opened. The power windows will continue to work for up to 10 minutes or until any door is opened. Starting the Engine If the vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. To place the transmission in the proper gear: Move the shift lever to P (Park) or N (Neutral). The engine will not start in any other position. To restart the engine when the vehicle is already moving, use N (Neutral) only. 3-23 2. If the engine does not start after 5-10 seconds, especially in very cold weather (below 0°F or −18°C), it could be ﬂooded with too much gasoline. Try pushing the accelerator pedal all the way to the ﬂoor and holding it there as you hold the key in START for up to 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key and accelerator. If the vehicle starts brieﬂy but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. Notice: The engine is designed to work with the electronics in the vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty. Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in START for many seconds, cranking will be stopped after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Engine cranking can be stopped by turning the ignition switch to the ACC/ACCESSORY or LOCK/OFF position. Notice: Cranking the engine for long periods of time, by returning the key to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. 3-24 Fast Idle System Fast Idle System with Switch If the vehicle has this feature it is available only with cruise control. The manual fast idle switch is operated using the cruise control buttons located on the left hand side of the steering wheel. This system can be used to increase engine idle speed whenever the following conditions are met: • The park brake is set. • The brake pedal is not pressed. • The vehicle must not be moving and the accelerator must not be pressed. To control the fast idle: • To Enable the Fast idle, press and release the Cruise Control On/Off button and ensure that the LED is lit. • For the preset Fast Idle, press and release the cruise set switch. This will set the preset fast idle speed. • For the variable fast idle, press and hold the accelerator at the desired RPM, then press and release the cruise control cruise set switch to set the desired idle speed. When the fast idle is active the Driver Information Center (DIC) will display “FAST IDLE ON.” One of the following actions will turn off the fast idle: • Pressing the brake. • Selecting the Cancel button. • Releasing the Parking Brake. • The transmission shifter is moved out of P (Park) or N (Neutral). • Selecting the cruise control on/off button when it was previously on. Engine Coolant Heater If the vehicle has the DURAMAX Diesel engine, see the DURAMAX Diesel manual for more information. The engine coolant heater can provide easier starting and better fuel economy during engine warm-up in cold weather conditions at or below 0°F (−18°C). Vehicles with an engine coolant heater should be plugged in at least 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). 3-25 To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord for the engine coolant heater is located on the driver side of the engine compartment and is attached to the hose for the power steering reservoir. 3. Plug it into a normal, grounded 110-volt AC outlet. { WARNING: 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 and prevent damage. 3-26 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. Automatic Transmission Operation (Six Speed Automatic Transmission) Vehicles with a six speed automatic transmission have a shift position indicator within the instrument panel cluster. There are several different positions for the shift lever. 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 3-36 for more information. { WARNING: 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 3-36. If you are pulling a trailer, see Towing a Trailer on page 5-26. 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 5-16. N (Neutral): In this position, the engine does not connect with the wheels. To restart when you are already moving, use N (Neutral) only. Also, use N (Neutral) when the vehicle is being towed. { WARNING: 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. 3-27 D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, and you are: • Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. • 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 or driving on steep hills. 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 5-9. 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 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 temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings. The shift quality of a new vehicle may not be ideal because the Adaptive Shift Control process may not have determined the best settings for a particular shift or condition. Shift quality will improve with continued driving. When temperatures are very cold, the 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 lets drivers select the range of gears appropriate for current driving conditions. If the vehicle has this feature, see Range Select Mode later in this section. 3-28 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. See Range Select Mode later in this section. 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. See Range Select Mode later in this section. 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. 1 (First): This position reduces vehicle speed without using the brakes. You can use it for major/severe downgrades where the vehicle would otherwise accelerate due to steepness of grade. When you shift to 1 (First) it provides the lowest gear appropriate to current road speed and continues to downshift as the vehicle slows, eventually downshifting to 1 (First) gear. The transmission can be held in 1 (First) gear using Range Select Mode or the shift lever. See Range Select Mode later in this section. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by 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. Range Selection Mode 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. 3-29 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 current driving conditions. When M (Manual Mode) is selected a number displays in the DIC 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 3-33. 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 Low Traction Mode can assist in vehicle acceleration when road conditions are slippery. 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. 3-30 Automatic Transmission Operation (Four Speed Automatic Transmission) There are several different positions for your shift lever. P (Park): This position locks your rear wheels. It is the best position to use when you start the engine because the vehicle cannot move easily. { WARNING: 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 3-36. If you are pulling a trailer, see Towing a Trailer on page 5-26. Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. You must ﬁrst press the brake pedal before you can shift from P (Park) with the ignition in ON/RUN. If you cannot shift out of P (Park), ease pressure on the shift lever and push the shift lever all the way into P (Park) as you maintain brake application. Then move the shift lever into another gear. See Shifting Out of Park on page 3-37. 3-31 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 5-16. 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. { WARNING: 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. 3-32 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: • Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. • Going about 35 mph (55 km/h) or more, push the accelerator all the way down. You will shift down to the next gear and have more power. Downshifting the transmission in slippery road conditions could result in skidding, see “Skidding” under Loss of Control on page 5-9. 3 (Third): This position is also used for normal driving. However 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. You should use 3 (Third) (or a lower gear as needed) when towing a trailer to minimize heat build-up and extend the life of the transmission. 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. You may use this feature for reducing torque to the rear wheels when you are trying to start the vehicle from a stop on slippery road surfaces. 1 (First): 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 will not shift into ﬁrst gear until the vehicle is going slowly enough. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. 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. Tow/Haul Mode Vehicles with an automatic transmission have a tow/haul mode. The tow/haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when towing or hauling heavy loads. Turn the tow/haul mode on and off by pressing the button, located to the right of the steering wheel on the instrument panel. When tow/haul is on, a light on the instrument panel cluster will come on. 3-33 Cruise Grade Braking (Six Speed Automatic Transmission) Cruise Grade Braking operates only while cruise control is engaged in Tow/Haul mode. Cruise Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades in cruise control by automatically shifting to lower gears when the cruise set speed is exceeded. While in the Range Selection Mode (RSM) mode, cruise grade braking is not available. See Automatic Transmission Operation (Six Speed Automatic Transmission) on page 3-26 or Automatic Transmission Operation (Four Speed Automatic Transmission) on page 3-31. See Tow/Haul Mode Light on page 4-36 for more information. Also see “Tow Haul Mode” under Towing a Trailer on page 5-26 for more information. Grade Braking (Six Speed Automatic Transmission) The Grade Braking shift modes can be activated by pressing the tow/haul button on the dash. 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 (Six Speed Automatic Transmission) on page 3-26 or Automatic Transmission Operation (Four Speed Automatic Transmission) on page 3-31 for more information on the Range Selection Mode. Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by automatically shifting to lower gears when the driver desires to slow the vehicle by applying the brake. This reduces wear on the braking system and increases control of the vehicle. Also see Towing a Trailer on page 5-26 for more information. 3-34 Parking Brake To set the parking brake, hold the regular brake pedal, then push down the parking brake pedal. If the ignition is on, the brake system warning light will come on. To release the parking brake, hold the regular brake pedal down. Pull the handle, located just above the parking brake pedal, with the parking brake symbol, to release the parking brake. If the ignition is on when the parking brake is released, the brake system warning light will go off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Verify that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on a hill, see Towing a Trailer on page 5-26. 3-35 Shifting Into Park { WARNING: 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. If you are pulling a trailer, see Towing a Trailer on page 5-26. 1. Hold the brake pedal down and set the parking brake. See Parking Brake on page 3-35 2. Move the shift lever into P (Park) by pulling the shift lever toward you and moving it up as far as it will go. 3. Turn the ignition key to LOCK/OFF. 4. 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). 3-36 Leaving the Vehicle With the Engine Running { WARNING: 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. 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. If you have to leave the vehicle with the engine running, be sure the 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 the vehicle 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 3-36. 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, so you can pull the shift lever out of P (Park). Shifting Out of Park The vehicle has an automatic transmission shift lock control system. You have to fully apply the brakes before you can shift from P (Park) when the ignition is in ON/RUN. See Automatic Transmission Operation (Six Speed Automatic Transmission) on page 3-26 or Automatic Transmission Operation (Four Speed Automatic Transmission) on page 3-31. The shift lock control system is designed to do the following: • Prevent the ignition key from being removed unless the shift lever is in P (Park). • Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN and the regular brake pedal is applied. The shift lock control system is always functional except in the case of a dead battery or low voltage (less than 9 V) 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 6-41 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, push 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. 3-37 Parking Over Things That Burn WARNING: (Continued) { WARNING: 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. Engine Exhaust { WARNING: Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. WARNING: (Continued) 3-38 Exhaust may enter the vehicle if: • The vehicle idles in areas with poor ventilation (parking garages, tunnels, deep snow that may block underbody airﬂow or tail pipes). • The exhaust smells or sounds strange or • The exhaust system leaks due to corrosion or different. damage. • The vehicle’s exhaust system has been modiﬁed, damaged or improperly repaired. • 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: • Drive it only with the windows completely down. • 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. 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. { WARNING: { WARNING: 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 3-38. 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. 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). Follow the proper steps to be sure the vehicle will not move. See Shifting Into Park on page 3-36. If parking on a hill and pulling a trailer, see Towing a Trailer on page 5-26. 3-39 Mirrors Outside Towing Mirrors Vehicles with towing mirrors can be adjusted manually for a clear view of the objects behind you. On the lower portion of each mirror there is an auxiliary convex mirror that can be adjusted manually to provide an extended ﬁeld of view. The mirrors can be manually folded in or out. Manual Rearview Mirror Hold the inside rearview mirror in the center to move it for a clearer view behind your vehicle. Adjust the mirror to avoid glare from the headlamps behind. Push the tab forward for daytime use and pull it for nighttime use. If you have a cargo van without the rear door glass, the vehicle may not have an inside rearview mirror. Outside Manual Mirrors Adjust the mirrors by pressing the mirror up and down and left and right so you can see a little of the side of your vehicle, and have a clear view of objects behind you. The mirrors can be manually folded in or out. On the lower portion of each mirror is an auxiliary convex mirror. A convex mirror’s surface is curved so you can see more from the driver seat. The auxiliary convex mirrors can be adjusted manually by pressing the mirror. 3-40 Outside Power Mirrors Outside Convex Mirror Vehicles with outside power mirrors have controls located on the driver side door. Select each mirror by turning the knob clockwise for the passenger side mirror or counterclockwise for the driver side mirror. The center position is neutral. Then, adjust the mirror angle by moving the knob in the desired direction. The auxiliary convex mirrors can only be adjusted manually. { WARNING: 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. 3-41 Outside Heated Mirrors For vehicles with heated mirrors: < (Rear Defogger): Press to heat the mirrors. An indicator light in the button lights when the outside heated mirrors are activated. See “Rear Window Defogger” under Climate Control System on page 4-15 for more information.

So, do not use the 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 excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. With cruise control, a speed of about 25 mph (40 km/h) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 25 mph (40 km/h). When the brakes are applied, cruise control is turned off. If the vehicle has StabiliTrak®, and the system begins to limit wheel spin, cruise control will automatically disengage. See StabiliTrak® System on page 5-5. When road conditions allow the cruise control to be safely used again, it can be turned back on. The cruise control buttons are located on left side of the steering wheel. Setting Cruise Control Cruise control will not work if the parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster comes on after the cruise control has been set to the desired speed. T (On/Off): This button can both activate and turn off the system.

SET − (Set/Coast): Press to set the speed or make the vehicle decelerate. [ (Cancel): Press to cancel cruise control without erasing the set speed from memory. { WARNING: 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. Press the I button. 2. Get up to the desired speed. 3. Press the SET− button located on the steering wheel and release it. 4. Take your foot off the accelerator. 4-7 Resuming a Set Speed If the cruise control is set at a desired speed and then the brakes are applied, this shuts off the cruise control. But it does not need to be reset. Once the vehicle speed reaches about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle returns to the previously set speed and stays there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: • Press and hold the +RES button on the steering wheel until the desired speed is reached, then release it. • To increase vehicle speed in small increments, press the +RES button. Each time this is done, the vehicle goes about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control To reduce the vehicle speed while using cruise control: • Press and hold the SET– button on the steering wheel until the desired lower speed is reached, then release it. • To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time this is done, the vehicle goes about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previous set cruise speed. 4-8 Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle’s speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle’s speed down. When the brakes are applied the cruise control turns off. Ending Cruise Control There are three ways to end cruise control: • Step lightly on the brake pedal. • Press the [ button on the steering wheel. • Press the I button on the steering wheel. Erasing Speed Memory The cruise control set speed memory is erased when the cruise control or the ignition is turned off. Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. It controls the following systems: • Headlamps • Taillamps • Parking Lamps • License Plate Lamps • Instrument Panel Lights 4-9 2 (Headlamps): Turns on the headlamps together with the following lamps listed below. • Parking Lamps • Instrument Panel Lights • Taillamps • License Plate Lamps If the headlamps are turned on while the vehicle is on, the headlamps turn off automatically 10 minutes after the ignition is turned off. If the headlamps are turned on while the vehicle is off, the headlamps will continue to stay on. To prevent the battery from being drained, turn the control to the 9 position. A warning chime sounds if the driver door is opened while the ignition switch is off and the headlamps are on. To change the headlamps from low beam to high beam, push the turn signal/multifunction lever toward the instrument panel. The exterior lamps control has four positions: O (Off): Brieﬂy turn the control to this position to turn the automatic headlamps and daytime running lamps (DRL) off or back on. For vehicles ﬁrst sold in Canada, the off position only works for vehicles that are shifted into the P (Park) position. AUTO (Automatic): Turns on the headlamps automatically at normal brightness, together with the following: • Parking Lamps • Instrument Panel Lights • Taillamps • License Plate Lamps ; (Parking Lamps): Turns on the parking lamps together with the following: • Instrument Panel Lights • Taillamps • License Plate Lamps 4-10 Headlamps on Reminder If a door is open, a reminder chime sounds when the headlamps or parking lamps are manually turned on and the key is out of the ignition. To turn off the chime, turn the headlamp switch to off or auto and then back on, or close and re-open the door. In the auto mode, the headlamps turn off once the ignition is in LOCK/OFF or may remain on until the headlamp delay ends, if enabled in the Driver Information Center (DIC). See “Exit Lighting” under DIC Vehicle Customization on page 4-52. Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system comes on in daylight when the following conditions are met: • The ignition is on. • The exterior lamps control is in the AUTO position. • The shift lever is not in P (Park). • The light sensor determines it is daytime. When the DRL are on, the taillamps, sidemarker, instrument panel and other lamps will not be on. The automatic headlamp system automatically switches from DRL to the headlamps depending on the darkness of the surroundings. To turn off the DRL, turn the exterior lamp control to the off position and then release it. For vehicles ﬁrst sold in Canada, the transmission must be in the P (Park) position, before the DRL can be turned off. Automatic Headlamp System When it is dark enough outside and the headlamp switch is in AUTO, the automatic headlamp system turns on the headlamps, along with the taillamps, sidemarker, parking lamps, roof marker 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. For vehicles ﬁrst sold in Canada, the transmission must be in the P (Park) position, before the automatic headlamp system can be turned off. The vehicle has a light sensor located on the top of the instrument panel. Do not cover the sensor or the system will come on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage or tunnel. 4-11 Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The dome lamps can also be turned on by turning the instrument panel brightness knob, located on the instrument panel to the left of the steering column, clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. 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 is only affected when the light sensor sees a change in lighting lasting longer than the delay. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it takes approximately 30 seconds for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 4-12. Instrument Panel Brightness The knob for this feature is located next to the exterior lamps control. D (Instrument Panel Lights): Push the knob to extend and then turn clockwise or counterclockwise to brighten or dim the instrument panel lights and the radio display. This only works if the headlamps or parking lamps are on. To turn on the dome lamps, with the vehicle doors closed, turn the knob all the way clockwise. 4-12 Dome Lamp Override The dome lamp override button is located next to the exterior lamps control. The dome lamp override sets the dome lamps to remain off or come on automatically when a door is opened. E (Dome Lamp Override): Press the button in and the dome lamps remain off when a door is opened. Press the button again to return it to the extended position so that the dome lamps come on when a door is opened. Entry/Exit Lighting The vehicle has an illuminated entry/exit feature. The dome lamps come on if the dome override button is in the out position, when a door is opened or the key is removed from the ignition. Reading Lamps For vehicles with reading lamps, press the button located next to each lamp to turn it on or off. The vehicle may also have reading lamps in other locations. The lamps cannot be adjusted. Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. 4-13 A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 4-44. Battery Run-Down Protection This feature shuts off the dome lamps if they are left on for more than 10 minutes when the ignition is in LOCK/OFF. This helps to prevent the battery from running down. 4-14 Accessory Power Outlet(s) The accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular phone. The vehicle may have two accessory power outlets located on the instrument panel. To use the accessory power outlet lift the cover. The spring cap cover closes by itself when the outlet is empty. Certain power accessory plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer for additional information on the accessory power plugs. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Notice: damage not covered by the vehicle warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Improper use of the power outlet can cause If papers, pins, or other ﬂammable items Ashtray(s) and Cigarette Lighter For vehicles with an ashtray it is located in the center console or on the instrument panel. Pull up on the ashtray door to open it if it is in the console or pull the door open it if it is on the instrument panel.

If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service. { WARNING: If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 4-23 for more information, including important safety information. Charging System Light Voltmeter Gage This light comes on brieﬂy when the ignition key is turned to START, but the engine is not running, as a check to show it is working. When the engine is not running, but the ignition is on, this gage shows the battery’s state of charge in DC volts. If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 4-44 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner. When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. 4-27 When the ignition is on, the brake system warning light also comes on when the parking brake is set. See Parking Brake on page 3-35 for more information. The light stays on if the parking brake does not fully release. If it stays on after the parking brake is fully released, it means the vehicle has a brake problem. If the light comes on while driving, pull off the road and stop carefully. The pedal might be harder to push, or the pedal might go closer to the ﬂoor. It could take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 5-22. { WARNING: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service. The vehicle can be only driven for a short time with the reading in either warning zone. If it must be driven, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Brake System Warning Light The vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking, both need to work. If the warning light comes on, there could be a brake problem. Have the brake system inspected right away. United States Canada This light should come on brieﬂy when ignition key is turned to ON/RUN. If it does not come on, have it ﬁxed so it will be ready to warn if there is a problem. 4-28 Antilock Brake System (ABS) Warning Light For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 4-44 for all brake related DIC messages. For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. StabiliTrak® Indicator Light For vehicles with the StabiliTrak® system, this light comes on or ﬂashes, according to the description table for the StabiliTrak system. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light comes on while driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 4-28. For more information, see StabiliTrak® System on page 5-5. Three chimes sound if the light turns on and one chime if the light turns off. If this light remains on steady, the vehicle needs to be taken in for service. 4-29 Engine Coolant Temperature Gage Tire Pressure Light For vehicles with a tire pressure monitoring system, this light comes on brieﬂy when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gage will read 100°C (210°F) or less. If the vehicle is pulling a load or going up hills, it is normal for the temperature to ﬂuctuate and approach the 122°C (250°F) mark. If the gage reaches the 125°C (260°F) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 6-33. 4-30 When the Light is On Steady This indicates that one or more of the tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See Driver Information Center (DIC) on page 4-37 for more information. Stop and check the tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Inﬂation - Tire Pressure on page 6-63 for more information. When the Light Flashes First and Then is On Steady This indicates that there may be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor Operation on page 6-66 for more information. Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. This light should come on when the ignition is on, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer/retailer. If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. 4-31 If the vehicle is continually driven with this Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: light on, after a while, the emission controls might not work as well, the vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 6-3. This light comes on during a malfunction in one of two ways: Light Flashing: A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required. To prevent more serious damage to the vehicle: • Reduce vehicle speed. • Avoid hard accelerations. • Avoid steep uphill grades. • If towing a trailer, reduce the amount of cargo being hauled as soon as it is possible. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the key off, wait at least 10 seconds, and restart the engine. If the light is still ﬂashing, follow the previous steps and see your dealer/retailer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. 4-32 An emission system malfunction might be corrected by doing the following: • Make sure the fuel cap is fully installed. See Filling the Tank on page 6-10. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. • If the vehicle has been driven through a deep puddle of water, the vehicle’s electrical system might be wet. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off. • Make sure to fuel the vehicle with quality fuel. Poor fuel quality causes the engine not to run as efficiently as designed and can cause: stalling after start-up, stalling when the vehicle is changed into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Gasoline Octane on page 6-6. If none of the above have made the light turn off, your dealer/retailer can check the vehicle. The dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection: • The vehicle will not pass this inspection if the check engine light is on with the engine running, or if the key is in ON/RUN and the light is not on. • The vehicle will not pass this inspection if the OBD II (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if the battery has recently been replaced or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/retailer can prepare the vehicle for inspection. 4-33 A reading in the low pressure zone may be caused by a dangerously low oil level or other problem causing low oil pressure. Check your oil as soon as possible. { WARNING: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil. Oil Pressure Gage United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. 4-34 Oil Pressure Light { WARNING: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil. This light comes on brieﬂy while starting the engine. If it does not, have the vehicle serviced by your dealer/ retailer. If the system is working normally the indicator light then goes off. If the light comes on and stays on, it means that oil is not ﬂowing through the engine properly. The vehicle could be low on oil and it might have some other system problem. Security Light For information regarding this light and the vehicle’s security system, see PASS-Key® III+ Electronic Immobilizer Operation on page 3-20. 4-35 Cruise Control Light Tow/Haul Mode Light The cruise control light comes on whenever the cruise control is set. This light comes on when the Tow/Haul mode has been activated. The light goes out when the cruise control is turned off. See Cruise Control on page 4-6 for more information. Highbeam On Light For more information, see Tow/Haul Mode on page 3-33. Fuel Gage This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 4-5 for more information. United States Canada The fuel gage, when the ignition is on, indicates how much fuel is left in the vehicle’s fuel tank. 4-36 An arrow on the fuel gage indicates the side of the vehicle the fuel door is on. The gage ﬁrst indicates empty before the vehicle is out of fuel, and the fuel tank should be refueled soon. Listed are four situations customers might experience with the fuel gage. None of these indicate a problem with the fuel gage: • At the gas station, the fuel pump shuts off before the gage reads full. • It takes a little more or less fuel to ﬁll up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. • The gage moves a little while turning a corner or speeding up. • The gage does not go back to empty when the ignition is turned off. If the vehicle has the DURAMAX Diesel engine, see the DURAMAX Diesel manual for more information. Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC). All messages will appear in the DIC display located at the bottom of the instrument panel cluster. The DIC buttons are located on the instrument panel, next to the instrument panel cluster. The DIC comes on when the ignition is on. After a short delay, the DIC will display the information that was last displayed before the engine was turned off. The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. If your vehicle has these features, the DIC also displays the compass direction and the outside air temperature when viewing the trip and fuel information. The compass direction appears on the top right corner of the DIC display. The outside air temperature automatically appears in the bottom right corner of the DIC display. If there is a problem with the system that controls the temperature display, the numbers will be replaced with dashes. If this occurs, have the vehicle serviced by your dealer/retailer. The DIC also allows some features to be customized. See DIC Vehicle Customization on page 4-52 for more information. 4-37 DIC Operation and Displays The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, next to the instrument panel cluster.
