Safety Locks
The vehicle has rear door security locks to prevent passengers from opening the rear doors from the inside.

Open the rear doors to access the security locks on the inside edge of each door.
To set the locks, insert a key into the slot and turn it to the horizontal position. The door can only be opened from the outside with the door unlocked. To return the door to normal operation, turn the slot to the vertical position.
