Child-proof locks for the rear doors
WARNING
Children could open a rear door from inside
the vehicle. This could result in serious
injuries or an accident. Therefore, when children ride in the rear always secure
the rear
doors with the child-proof locks.
You secure each door individually with the child-proof locks on the rear doors. A door secured with a child-proof lock cannot be opened from inside the vehicle. When the vehicle is unlocked, the door can be opened from the outside.

Example: Sedan
•► To activate: press the child-proof lock lever up in the direction of arrow 1.
•► Make sure that the child-proof locks are working properly.
•► To deactivate: press the child-proof lock lever down in the direction of arrow 2.
