Doors and Locks

Door Locks

WARNING:
Unlocked doors can be dangerous.
• Passengers, especially children, can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. The chance of being thrown out of the vehicle in a crash is increased if the doors are not locked. So, all passengers should wear safety belts properly and the doors should be locked whenever the vehicle is driven.
• Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock the vehicle whenever leaving it.
• Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening.

There are several ways to lock and unlock your vehicle.

From the outside, use either the key or the Remote Keyless Entry (RKE) transmitter.

From the inside, use the power door lock switches or manual lock knobs. The manual lock knobs are located at the top of the door panel near the window.

When all doors have been closed, the doors will lock automatically after several seconds. If any door is opened before this, the timer will reset itself once all the doors have been closed again.

Pressing the driver or passenger power door lock switch again or the RKE transmitter button will override this feature.

Personal Choice Programming

The delayed locking feature can be turned on or off, using the Driver Information Center (DIC) to program this feature. See “DELAY DOOR LOCK” under DIC Vehicle Customization.

Programmable Automatic Door Locks

Your vehicle is programmed so that, when the doors are closed, the ignition is on, and the shift lever is moved out of P (Park), all the doors will lock. The doors will unlock every time you stop the vehicle and move the shift lever into P (Park).

If someone needs to get out while your vehicle is not in P (Park), have the person use the manual lock knob or power door lock switch. When the door is closed again, it will not lock automatically. Use the manual lock knob or power door lock switch to lock the door.

If your vehicle has a Driver Information Center (DIC), you can choose various lock and unlock settings.
