Passive locking
On vehicles with electronic key
system, this feature locks the vehicle
automatically after several seconds if an electronic key has been
recognised previously inside the
vehicle, all doors have then been
closed and the electronic key does
not remain within the vehicle.
If the electronic key remains in the
vehicle or the ignition is not off,
passive locking will not be permitted.
If there have been two or more
electronic keys in the vehicle and the
ignition was on once, the feature
locks the vehicle if just one electronic
key is taken out of the vehicle.
To prevent passive locking of the
vehicle e.g. when refuelling or if
passengers remain in the vehicle, the system must be disabled.
