Your vehicle is equipped with rear door security locks that help prevent passengers from opening the rear doors on your vehicle from the inside. To use one of these locks do the following:
On the inside of the rear door will be a lock. Push the lever up to engage the safety lock.
The rear doors on your vehicle cannot be opened from inside the vehicle when this feature is in use. If you want to open the rear door when the security lock is on, unlock the door from the inside and then open the door from the outside.
The rear door locks will now work normally.
