Luggage compartment lid
The luggage compartment lid should always
be operated via the radio remote control.
The lock cylinder for the luggage compart-
ment lid is integrated into the handle.
Emergency door locking
In the event of failure of the central locking,
e.g. due to power supply faults, each door can
be individually locked without using the lock
cylinder.
Firstly, with the door open, the cap must be
removed. Emergency locking is effected by
inserting the ignition key.
After the door has been closed, it is not possi-
ble to open it from the outside.
The door can be opened from the inside by
actuating the door release handle twice.
Continuous locking of luggage compartment
If the lock cylinder is in the horizontal posi-
tion with the key removed, the luggage com-
partment lid is no longer included in the
central locking system. Opening is then only
possible via the centre unlocking button of
the radio remote control.
When the lock cylinder is in the vertical posi-
tion, the lid is an integral part of the central
locking system.
Manual unlocking and opening
is effected by turning the key to the left.
In this position, it is not possible to remove
the key, which must subsequently be returned
to the vertical position.
Thus, it is ensured that the luggage compart-
ment lid is an integral part of the central lock-
ing system.

munication bar in the top part of the rear win-
dow for the first time.
