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 approximately 9 mph
(15 km / h) or more.
If a door is opened from the inside at speeds of
approximately 9 mph (15 km / h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.
When a door is opened from the inside, the complete
vehicle is unlocked, if the vehicle is previously unlocked
in the global remote control mode.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 236), the
vehicle doors will lock if the left front wheel as well as
the right rear wheel spin at vehicle speeds of
approximately 9 mph (15 km / h) or more.
Emergency unlocking in case of accident
