Power Door Locks (If Equipped) Rear Door SecurityLock (If Equipped) With this feature, you can lock the rear doors they so can't be opened from the inside by passengers. Move the lock up to lock the doors and down to release the door locks. Lockout Prevention If your vehicle has power door locks, the switch is located on the armrest. Remove the ignition key and press LOCK to lock all the doors at once. To unlock the doors, press the raised area next to the key symbol. On four-door models, the lever on each rear door works only that door's lock. To protect you from locking your key in the vehicle, this feature stops the power door locks from locking when the keys are in the ignition and a door is open. If the power lock switch is pressed when a door is open and the key is in the ignition, all the doors will lock and the driver's door will unlock. 2-5
