Automatic central locking
The doors and the tailgate automatically
lock when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km / h) or more.
The locking knobs in the doors move down.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
mode using the control system
(page 180).
i
If the tailgate lid comes into contact with an
object while closing (e.g. luggage that has been
piled too high) in the upper motion sequence, the
closing procedure is stopped and the tailgate re-
opens slightly.
i
The doors are designed to unlock automati-
cally after an accident if the force of the impact
exceeds a preset threshold. The vehicle locks au-
tomatically when the ignition is switched on and
the wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km/h) or more. You could
therefore lock yourself out when the vehicle


is pushed or towed


is on a test stand
