Pull the cap out of the opening Fig. 2.
Insert the key in the slot inside and turn it as far as the stop to the right (if the door is on the right* side) or to the left (if the door is on the left side).
Once the front passenger's door/rear doors* have been closed, they can no longer be opened from the outside. The door can be opened from the inside by pulling the door handle. If the child lock is engaged on one of the rear doors*, the door can be opened by pulling the inside door handle and then opening the door from the outside.
On vehicles with an anti-theft alarm system*, do not leave anyone (especially children) in the car if it is locked from the outside and the safelock mechanism* is activated: the doors and windows cannot then be opened from the inside
