Keys
The key set
1 Master keys with remote control: they
determine the functions of the Key
Memory, refer to page
31 .
You can mark individual keys for subse-
quent identification by applying the col-
ored decals that you received when
accepting delivery of your vehicle
There is an extended-life battery
in every master key that is
charged automatically in the ignition
lock as you drive.
For this reason, if you have a master key
with remote control that is otherwise
not used, use that key approximately
once a year while driving for an
extended period to charge the bat-
tery.

Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. The system simultaneously
engages and releases the locks on the
> doors
> luggage compartment lid
> fuel filler door
> storage compartment between the
backrests
> opened manual convertible top.
The central locking system can be oper-
ated
> from outside using the remote control
or via the driver's door lock
> from inside via the central locking sys-
tem button.
If it is operated from inside, the fuel filler
door will not be locked. Refer to page
18 .
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle. It
prevents the doors from being unlocked
with the lock buttons or release handles.
The alarm system is also armed.
The central locking system unlocks auto-
matically in the event of an accident. In
addition, the hazard warning flashers and
interior lamps come on.
Remote control
The concept
The remote control provides two additional
functions for central locking.
> Switching on interior lamps, refer to
page
17 .
With this function, you can also search
for the vehicle when parked in an
underground garage, for instance
> Opening the luggage compartment lid
separately, refer to page
17 . It will open
slightly, regardless of whether it was
locked or unlocked.
Whenever you unlock or lock the vehicle,
you simultaneously deactivate/activate
the anti-theft system, disarm/arm the alarm
