Power Assist Steps

Warning

To avoid personal injury or property damage, before entering or exiting the vehicle, be sure the power assist step is fully extended. Do not step on the power assist step while it is moving. Never place hands or other body parts between the extended power assist step and the vehicle.

If equipped, the power assist steps, when enabled, will extend when the door is opened. They will retract three seconds after the door is closed or immediately if the vehicle starts moving. Keep hands, children, pets, objects, and clothing clear of the power assist steps when in motion.

The steps will reverse direction if there is an obstruction. If possible, carefully remove the obstruction, then open and close the door on the same side to complete the motion. If the obstruction is not cleared, the assist steps remain extended. Slight movement of the steps while extended is normal.

1. Place the vehicle in P (Park) and unlock the doors.
2. Kick the switch to extend the power assist step to the tire. A Driver Information Center (DIC) message displays.
3. Kick the switch again to return to normal operation.

Vehicle Security

This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.

Vehicle Alarm System

The indicator light, on the instrument panel near the windshield, indicates the status of the system.

Off: The alarm system is disarmed.
On Solid: The vehicle is secured during the delay to arm the system.
Fast Flash: The vehicle is unsecured. A door or the hood is open.
Slow Flash: Alarm system is armed.

Arming the Alarm System

1. Turn off the vehicle.
2. Lock the vehicle in one of two ways: . Use the remote key. With a door open, press Q on the interior of the door.
3. After 30 seconds, the alarm system will arm and the indicator light will begin to slowly flash. Pressing Q on the remote key a second time will bypass the 30- second delay and immediately arm the alarm system.

The vehicle alarm system will not arm if the doors are locked with the key. If the driver door is opened without first unlocking with the remote key, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing K on the remote key during the 10-second pre-alarm, the alarm will be activated. The alarm will also be activated if a passenger door or the hood is opened

Steering Column Lock

be turned and the vehicle must be started again indicates that the column lock mechanism is bound, the column locking device was unable to unlock the steering column, and the vehicle did not start.
If this happens, immediately turn the steering wheel from side to side to unbind the column lock. If this does not unlock the steering column, turn the vehicle off and open the driver door to reset the system. Then turn the vehicle on and immediately turn the steering wheel side to side for about 15 seconds. In some cases, it may take significant force to unbind the column.

Immobilizer Operation

This vehicle has a passive theft-deterrentsystem. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the vehicle is turned off. The system is automatically disarmed when the ignition is turned from off to on. The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system. The system has one or more remote keys matched to an immobilizer control unit in your vehicle. Only a correctly matched remote key will start the vehicle. If the remote key is ever damaged, you may not be able to start your vehicle.

When trying to start the vehicle, the security light may come on briefly when the ignition is turned on. If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again.
If the vehicle will not change ignition modes (accessory mode, on, off), and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the remote key pocket located in the center console. See Remote Key Operation 0 15.
If the ignition mode will not change with the other remote key or with the remote key in the remote key pocket, your vehicle needs service. If the ignition does change modes, the first remote key may be faulty. See your dealer who can service the
theft-deterrent system and have a new remote key programmed to the vehicle.
It is possible for the immobilizer system to learn new or replacement remote keys. Up to eight remote keys can be programmed for the vehicle. To program additional remote keys, see “Programming Remote Keys to the Vehicle” under Remote Key Operation 0 15.

Do not leave the remote key or device that disarms or deactivates the vehicle theft system in the vehicle.

Windows

Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke.

The vehicle aerodynamics are designed to improve fuel economy performance. This may result in a pulsing sound when either rear window is down and the front windows are up. To reduce the sound, open either a front window or the sunroof, if equipped.

Power Windows

Children could be seriously injured or killed if caught in the path of a closing window. Never leave the remote key in a vehicle with children. When there are children in the rear seat, use the window lockout switch to prevent operation of the windows. See Keys 0 14.
