Keys

The key set

1 Master keys with remote control

unit – these keys determine the func-
tions of the Key Memory, refer to
page

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 the
remote control feature there is an

extended-life battery that is charged
automatically in the ignition lock as you
drive.
For this reason, if you have master keys
with the remote control feature that are
not being used otherwise, use those
keys at least once a year while driving
for an extended period to charge the
battery.

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 locks on the:
> doors

> luggage compartment lid

> fuel filler door.
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

When the system is actuated from the
outside, the anti-theft system is also
activated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also activated or deactivated.

If locked from inside, the central locking
system unlocks the vehicle automati-
cally in the event of an accident. In
addition, the hazard warning flashers
and interior lamps come on.
