1-16 Keys, Doors and Windows Lockout Protection If the power door lock switch is pressed when the key is in the ignition and a door is open, all the doors will lock and only the driver door will unlock. If the doors are closed, they can be locked by using the Remote Keyless Entry (RKE) transmitter. Be sure to remove the key from the ignition when locking the vehicle. This feature can be overridden by pressing the lock button on the RKE transmitter or by pressing the power lock switch a second time. On vehicles with a Keyless Access System, the system can be programmed to alert you when all the doors are closed and a transmitter has been left inside of the vehicle. See Vehicle Personalization on page 4‑51 for more information. Safety Locks The vehicle has rear door security locks. These prevent passengers from opening the rear doors from the inside. To set the locks: 1. Insert the key into the security lock slot and turn it so the slot is in the horizontal position. 2. Close the door. When you want to open a rear door when the security lock is on: 1. Unlock the door using the Remote Keyless Entry (RKE) or Keyless Access System transmitter, if the vehicle has one, the power door lock switch, or the rear door manual lock. 2. Open the door from the outside. To cancel the rear door security lock: 1. Unlock the door and open it from the outside. 2. Insert the key into the security lock slot and turn it so the slot is in the vertical position. Lock Label shown 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.
