Keys
The key set
1 Master keys with remote control unit
– these keys determine the functions
of the Key Memory. Refer to page
64 .
You can mark the individual keys for
subsequent identification by apply-
ing the colored decals that you
received when accepting delivery of
your vehicle
In every master key with remote
control there is an extended-life
battery 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 other-
wise not used, use that key at least
once every year while driving for an
extended period to charge the bat-
tery.
<
2 Spare key – for storage in a safe
place, such as in your wallet. This key
is not intended for constant use. The
luggage compartment lid and the
glove compartment cannot be locked
and unlocked with this key. This is
useful for valet parking, for example.
Central locking system
The concept
The central locking system engages
and releases the following locks at the
same time:
> doors
> luggage compartment lid
> fuel filler door and
> glove compartment.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
> from outside via the door lock and
using the remote control
> from inside via the central locking
system button.
If it is operated from inside, the fuel
filler door will not be locked, refer to
page
34 .
Operating it from outside simulta-
neously activates the anti-theft system,
which prevents the doors from being
unlocked via the door lock buttons or
the door release handles.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.
