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.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the engine running, the vehicle doors will lock if
the left front wheel spins at vehicle speeds of
approximately 9 mph (15 km/ h) or more.
To prevent vehicle door locks from locking, deactivate
the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
retractor deploys (this is intended to aid rescue and
exit). However, the key must still be in the steering lock
position 1 or 2.
Additionally the hazard warning flashers turn on
automatically and the interior lights switch on for
approximately 30 minutes.
