Programmable Automatic Door Locks Your vehicle was programmed from the factory so that when the doors are closed, the ignition is on and the shift lever is moved out of PARK (P), all the doors will lock. The front doors can still be opened from the inside while the doors are locked. If a rear passenger needs to exit the vehicle, have that person use the manual knob or use the power door lock switch on either front door. When the door is closed again, it will not lock automatically. Use the manual knob or the power door lock switch to lock the door. The doors were also programmed from the factory to unlock every time the shift lever is moved back into PARK (P). The power door locks can be programmed through the radio display. The radio display allows you to choose various lock and unlock settings. For more information on programming, see Vehicle Personalization on page 2-60. Rear Door Security Locks Your vehicle has rear door security locks. These prevent passengers from opening the rear doors from the inside. The rear door security locks are located on the inside edge of each rear door. The rear doors must be open to access them. The label showing lock and unlock positions is located near the lock. Lock Label shown To set the locks, do the following: 1. Insert the key into the security lock slot and turn it so the slot is in the horizontal position. 2. Close the door. 2-15
