To save fuel, run the engine for only short periods as needed to warm the vehicle and then shut the engine off and close the window most of the way to save heat. Repeat this until help arrives but only when you feel really uncomfortable from the cold. Moving about to keep warm also helps.
If it takes some time for help to arrive, now and then when you run the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible to save fuel.
If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. See “Rocking the Vehicle to Get It Out” later in this section. The Traction Control System (TCS) can often help to free a stuck vehicle. See Traction Control/ Electronic Stability Control on page 9-44. If TCS cannot free the vehicle, see “Rocking the Vehicle to Get it Out” following.

(B-pillar). With the driver door open, you will find the label attached below the door lock post (striker). The tire and loading information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires on page 10-46 and Tire Pressure on page 10-53. There is also important loading information on the vehicle Certification/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for
the front and rear axles. See “Certification/Tire Label” later in this section.
“Steps for Determining Correct Load Limit– 1. Locate the statement "The
combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.

The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo. The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle. The Certification/Tire label also contains information about your Front Axle Reserve Capacity. And, if you do have a heavy load, you should spread it out.

1 (STOPPING THE ENGINE/LOCK/ OFF): When the vehicle is stopped, turn the ignition switch to LOCK/ OFF to turn the engine off. Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9-27. This position locks the ignition and steering wheel. It also locks the transmission on automatic transmission vehicles. The key can be removed in LOCK/OFF. The steering can bind with the wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ACCESSORY. If this does not work, then the vehicle needs service. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.
If the vehicle must be shut off in an emergency: 1. Brake using a firm and steady
pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.
2. Shift the vehicle to N (Neutral).
This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position.
4. Set the parking brake. See
Parking Brake on page 9-42.
{ Warning
Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.
If the vehicle cannot be pulled over, and must be shut off while driving, turn the ignition to ACC/ ACCESSORY.
{ Caution
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.

4 (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 and the ignition is in ACC/ACCESSORY or LOCK/OFF, and the key is in the ignition.
Ignition Positions (Keyless Access)
2 (ACC/ACCESSORY): This position lets things like the radio and the windshield wipers operate while the engine is off. It also unlocks the steering wheel. Use this position if the vehicle must be pushed or towed. 3 (ON/RUN): This position can be used to operate the electrical accessories and to display some instrument cluster warning and indicator lights. This position can also be used for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. The switch stays in this position when the engine is running. The transmission is also unlocked in this position on automatic transmission vehicles. If the key is left in the ACC/ ACCESSORY or ON/RUN position with the engine off, the battery could be drained. The vehicle may not start if the battery is allowed to drain for an extended period of time.
Vehicles with Keyless Access have pushbutton starting. Pressing the button cycles it through three modes: ACC/ACCESSORY, ON/RUN/START, and Stopping the Engine/OFF. The transmitter must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the Keyless Access system. See Remote Keyless Entry (RKE) System Operation (Key Access) on page 2-5 or Remote Keyless Entry (RKE) System Operation (Keyless Access) on page 2-8.

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 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 9-28.
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. You will then be able to pull the shift lever out of P (Park).
Shifting out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: . Prevent ignition key removal
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 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 10-79. To shift out of P (Park): 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

Parking over Things That Burn
{ 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.
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 the vehicle has an Active Fuel Management indicator, see Driver Information Center (DIC) (Base Level) on page 5-30 or Driver Information Center (DIC) (Uplevel) on page 5-32 for more information on using this display.
Engine Exhaust { Warning
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:
. 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 different.
. The exhaust system leaks
due to corrosion or damage. . The vehicle exhaust system
has been modified, damaged, or improperly repaired.

increase in the effort to shift out of P (Park). See “Torque Lock” under Shifting Into Park on page 9-28.
{ 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. 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 9-28 and Driving Characteristics and Towing Tips on page 9-74.
R (Reverse): Use this gear to back up.
{ Caution
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 the Vehicle Is Stuck on page 9-13. 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.
{ Caution 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 55 km/h (35 mph), push the accelerator pedal about halfway down.
. Going about 55 km/h (35 mph) or
more, push the accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has more power.
Use D (Drive) and Tow/Haul Mode when towing a trailer, carrying a heavy load, driving on steep hills, or driving off-road. 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 9-5.
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. The adaptive shift control process continually compares key shift parameters to pre-programmed ideal shifts stored in the transmission’s 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 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 allows selection of a range of gears appropriate for current driving conditions. If equipped, see “Range Selection Mode” under Manual Mode on page 9-34.

Normal Mode Grade Braking If equipped with a gasoline engine and an automatic transmission, Normal Mode Grade Braking is enabled when the vehicle is started, but is not enabled in Range Selection Mode. It assists in maintaining desired vehicle speeds when driving on downhill grades by using the engine and transmission to slow the vehicle. The first time the system engages for each ignition key cycle, a DIC message will be displayed. See Transmission Messages on page 5-45.
To disable or enable Normal Mode Grade Braking within the current ignition key cycle, press and hold the Tow/Haul button for five seconds. When the button is released, the requested mode change is made. A DIC message displays. See Transmission Messages on page 5-45. For other forms of grade braking, see Tow/Haul Mode on page 9-36

Range Selection Mode
If equipped, Range Selection Mode helps control the vehicle's transmission and vehicle speed
while driving downhill or towing a trailer by letting you select a desired range of gears. To use this feature: 1. Move the shift lever to
M (Manual Mode).
2. Press the plus/minus buttons on
the shift lever to select the desired range of gears for current driving conditions.
When the shift lever is moved from D (Drive) to M (Manual Mode), a number displays next to the M, indicating the current transmission range. This number is the highest gear that the transmission will command while operating in M (Manual Mode). All gears below that number are available. As driving conditions change, the transmission can automatically shift to lower gears.

For example, when 5 (Fifth) is selected, 1 (First) through 5 (Fifth) gears are automatically shifted by the transmission, but 6 (Sixth) cannot be used until the plus/minus button on the shift lever is used to change to the range. In vehicles with gasoline engines, when the shift lever is moved from D (Drive) to M (Manual Mode), a downshift may occur. The gear that the transmission is operating in when the shift lever is moved from D (Drive) to M (Manual Mode) determines if a downshift occurs. See the following chart.

Brakes
Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.
If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-25.

suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You may hear the ABS pump or motor operating and feel the brake pedal pulsate. This is normal. Braking in Emergencies ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.
If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle

{ Caution
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 parking 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 Driving Characteristics and Towing Tips on page 9-74.
Brake Assist The Brake Assist feature is designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates.
