The idle speed will go down as the 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. If the transmitter is not in the vehicle or something is interfering with the transmitter, the Driver Information Center (DIC) will display a message. See Remote Keyless Entry (RKE) System Operation on page 2-3 and Key and Lock Messages on page 5-36. If the battery in the RKE transmitter needs replacing, a DIC message displays. The vehicle can still be driven. See “Starting the Vehicle with a Low Transmitter Battery” in Remote Keyless Entry (RKE) System Operation on page 2-3. The vehicle has a Computer-Controlled Cranking System. This feature assists in
starting the engine and protects components. If the START button is pressed, 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 button is pressed 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 pressing the START button a second time.

2.
If the engine does not start after five to 10 seconds, especially in very cold weather (below −18°C or 0°F), 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 press the START button, for up to a maximum of 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 button and the 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.
Engine Heater Vehicles with the engine coolant heater can use this option in cold weather conditions at or below −18°C (0°F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting your vehicle. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above −18°C (0°F). To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the
electrical cord. The cord is clipped to the diagonal brace on the passenger side of the engine compartment.
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. If you do not, it could be damaged.
Contact your dealer for information on how long to use the heater in your particular area.

Driving and Operating
Torque Lock (Automatic Transmission) Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the transmission. This happens when parking on a hill and shifting the transmission into P (Park) is not done properly and then it is difficult to shift out of P (Park). To prevent torque lock, set the parking brake and then shift into P (Park). To find out how, see "Shifting Into Park" listed previously. If torque lock does occur, the vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift 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 movement of the shift lever
out of P (Park), unless the ignition is in ON/RUN/START and the 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 10-72. To shift out of P (Park): 1. Apply the brake pedal. 2. Turn the ignition to ON/RUN/
START.
3. Release the parking brake. See
Parking Brake (Electric) on page 9-30 or Parking Brake (Manual) on page 9-32.
4. Press the shift lever button. 5. Move the shift lever.
If unable to shift out of P (Park): 1. Fully release the shift lever
button.
2. While holding down the brake
pedal, press the shift lever button again.
3. Move the shift lever. If the shift lever will not move from P (Park), consult your dealer or a professional towing service.
Parking If the vehicle has a manual transmission, before getting out of the vehicle, move the shift lever into R (Reverse) if parking on a downhill slope. On a level surface or an uphill slope, use 1 (First) gear. Apply the parking brake. Turn the wheels toward the curb for a downhill slope, or away from the curb for an uphill slope. Once the shift lever has been placed into gear with the clutch pedal pressed in, turn the ignition to LOCK/OFF, and release the clutch.

Drive Systems
Brakes
All-Wheel Drive Vehicles with this feature always send engine power to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions.
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 5-20.
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 that 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

EPB Apply To apply the EPB: 1. Be sure the vehicle is at a
complete stop.
2. Lift up the EPB switch
momentarily.
The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come one, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. See Parking Brake Light on page 5-19. If the amber parking brake warning light is on, lift up on the EPB switch and hold it up. Continue to hold the switch until the red parking brake
status light remains on. If the amber parking brake warning light is on, see your dealer. If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is held up. If the switch is held up until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement. EPB Release To release the EPB: 1. Place the ignition in the ACC/
ACCESSORY or ON/RUN/ START position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the

Brake Assist This vehicle has a brake assist feature 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. The brake assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.
Hill Start Assist (HSA) This vehicle has an HSA feature, which may be useful when the vehicle is stopped on a grade. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. After the driver completely stops and holds the vehicle in a complete standstill on a grade, HSA will be automatically activated. During the transition period between when the driver releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds the braking pressure for a maximum of two seconds to ensure that there is no rolling. The brakes will automatically release when the accelerator pedal is applied within the two-second window. It will not activate if the vehicle is in a drive gear and facing downhill, or if the vehicle is facing uphill and in R (Reverse).
Ride Control Systems
Traction Control/ Electronic Stability Control
System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak®, an electronic stability control system. These systems help limit wheel slip and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling.

vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used and traction control or StabiliTrak begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck on page 9-11 and “Turning the Systems Off and On” later in this section.
The indicator light for both systems is in the instrument cluster. This light will:
Flash when TCS is limiting wheel spin. Flash when StabiliTrak is activated. Turn on and stay on when either system is not working.
If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.

Cruise Control { Warning
Cruise control can be dangerous where you cannot drive safely at a steady speed. 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 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). If the brakes are applied, the cruise control disengages.

(manual and automatic transmissions).
. Depress the clutch pedal for
several seconds or shift to Neutral (manual transmissions).
. Press *. . Press J. Erasing Speed Memory The cruise control set speed is erased from memory if J is pressed or if the ignition is turned off.
Adaptive Cruise Control If equipped with Adaptive Cruise Control (ACC), it allows the driver to select the cruise control set speed and following gap. Read this entire section before using this system. The following gap is the following time between your vehicle and a vehicle detected directly ahead in your path moving in the same direction. If no vehicle is detected in your path, ACC works like regular cruise control. ACC uses camera and radar sensors. See Radio Frequency Statement on page 13-15. If a vehicle is detected in your path, ACC can apply acceleration or limited, moderate braking to maintain the selected following gap. To disengage ACC, apply the brake. If ACC is controlling your vehicle speed when the Traction Control System (TCS) or StabiliTrak System activates, the ACC may automatically disengage. See Traction Control/Electronic Stability

Control on page 9-33. When road conditions allow ACC to be safely used, the ACC can be turned back on. ACC will not engage if the TCS or StabiliTrak electronic stability control system is disabled.
{ Warning
ACC has limited braking ability and may not have time to slow the vehicle down enough to avoid a collision with another vehicle you are following. This can occur when vehicles suddenly slow or stop ahead, or enter your lane. Also see “Alerting the Driver” in this section. Complete attention is always required while driving and you should be ready to take action and apply the brakes. See Defensive Driving on page 9-3.
{ Warning
Adaptive Cruise Control will not detect or brake for children, pedestrians, animals, or other objects. Do not use Adaptive Cruise Control when:
. On winding and hilly roads or
when the sensors are blocked by snow, ice, or dirt. The system may not detect a vehicle ahead. Keep the entire front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions. Adaptive Cruise Control performance is limited under these conditions.
. On slippery roads where fast
changes in tire traction can cause excessive wheel slip.

Each press cycles the gap button through three settings: Far, Medium, or Near. When pressed, the current gap setting displays briefly on the instrument cluster and HUD. The gap setting will be maintained until it is changed. Since each gap setting corresponds to a following time (Far, Medium, or Near), the following distance will vary based on vehicle speed. The faster the vehicle speed, the further back your vehicle will follow a vehicle detected ahead. Consider traffic and weather conditions when selecting the following gap. The range of selectable gaps may not be appropriate for all drivers and driving conditions. Changing the gap setting automatically changes the alert timing sensitivity (Far, Medium,
or Near) for the Forward Collision Alert (FCA) feature. See Forward Collision Alert (FCA) System on page 9-53.
Alerting the Driver
Approaching and Following a Vehicle
If ACC is engaged, driver action may be required when ACC cannot apply sufficient braking because of approaching a vehicle too rapidly. When this condition occurs, the collision alert symbol on the HUD will flash on the windshield. Either eight beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. See “Collision/Detection Systems” under Vehicle Personalization on page 5-43. See Defensive Driving on page 9-3.
The vehicle ahead symbol is in the instrument cluster and HUD display. The vehicle ahead symbol only displays when a vehicle is detected in your vehicle’s path moving in the same direction. If this symbol is not displaying, ACC will not respond to or brake to vehicles ahead. ACC automatically slows the vehicle down and adjusts vehicle speed to follow the vehicle in front at the selected follow gap. The vehicle speed increases or decreases to follow the vehicle in front of you, but will not exceed the set speed. It may apply limited braking, if necessary. When braking is active, the brake

lamps will come on. The automatic braking may feel or sound different than if the brakes were applied manually. This is normal.
Stationary or Very Slow-Moving Objects
{ Warning
Adaptive Cruise Control (ACC) may not detect and react to stopped or slow-moving vehicles ahead of you. For example, the system may not brake for a vehicle that it has never detected moving. This can occur in stop-and-go traffic or when a vehicle suddenly appears due to a vehicle ahead changing lanes. Your vehicle may not stop and could cause a crash. Use caution when using ACC. Your complete attention is always required while driving and you should be ready to take action and apply the brakes.
ACC Automatically Disengages ACC may automatically disengage and the driver will need to manually apply the brakes to slow the vehicle when:
The sensors are blocked. The Traction Control System (TCS) or electronic stability control system has activated or been disabled.
