Automatic central locking
With the automatic central locking system activated, the
doors and trunk are locked at vehicle speeds of approx.
9 mph (15 km/h) or more. The fuel filler flap remains
unlocked.
The automatic central locking function can be switched
on or off. See page 138 for “Individual settings”.
Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approx. 9 mph (15 km/h) or
more.
If a door is opened from the inside at speeds of approx.
9 mph (15 km/h) or less with the automatic central
locking activated, the door will again be automatically
locked at speeds of approx. 9 mph (15 km/h) or more.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: operation position, see page 224), the
vehicle doors will lock if the left front wheel as well as
the right rear wheel spin at vehicle speeds of approx.
9mph (15km/h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See page 138
for “Individual settings”.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
