Child-Protection Door Lock
To provide a safer environment for children riding in the
rear seat, the rear doors (if equipped) of your vehicle
have the Child-Protection Door Lock system.
To use the system, open each rear door, use a flat blade
screwdriver (or emergency key) and rotate the dial to
engage and disengage the Child-Protection locks. When
the system on a door is engaged, that door can only be
opened by using the outside door handle even if the
inside door lock is in the unlocked position.
