yellowblue Rear Door Security Locks Your vehicle is equipped with rear door security locks that help prevent passengers from opening the rear doors of your vehicle from the inside. When you want to open a rear door when the security lock is on: 1. Unlock the door from the inside. 2. Then open the door from the outside. To cancel the rear door lock: 1. Unlock the door and open it from the outside. 2. Move the lever all the way down. 3. Do the same for the other rear door. The rear door locks will now work normally. Anti-Lockout Feature To use this lock: 1. Move the lever on the door all the way up to the ENGAGED position. 2. Close the door. 3. Do the same thing to the other rear door lock. The rear doors of your vehicle cannot be opened from the inside when this feature is in use. Leaving your key in any ignition position with any door open will disable the use of the power door lock buttons as well as the lock button on the remote keyless entry transmitter. If you close the doors, you can lock them using the remote keyless entry transmitter. It is always recommended that you remove the ignition key when locking your vehicle. Note: The anti-lockout feature can be overridden by holding the driver's power door lock button for three seconds or longer. 2-6
