Automatic central locking
The doors and the tailgate lock automatically
when the vehicle is set into motion.

Open door only when conditions are safe to
do so.

automatically after an accident if the force of
the impact exceeds a preset threshold.

ignition is switched on and the wheels are
turning at vehicle speeds of approximately
9 mph (15 km/h) or more. You could
therefore lock yourself out when the vehicle
is pushed or towed or is on a test stand.
You can deactivate the automatic central
locking using the control system
