The central locking system allows you to lock and unlock all doors and the lug-
gage compartment lid at the same time.
Depending on the equipment configuration, the following applies after un-
locking.
▶ The turn signal lights flash twice as confirmation that the vehicle has been
unlocked.
▶ All the doors and the boot lid are unlocked.
▶ The interior light comes on.
▶ The Safelock system is switched off.
▶ The indicator light in the driver door stops flashing.

locked.
▶ All the doors and the luggage compartment lid are locked.
▶ The interior lamp goes out.
▶ The Safelock system is switched on.
▶ The warning light in the driver door begins flashing.
If the doors or the luggage compartment lid remain open after the vehicle has
been locked, the turn signal lights do not flash until they have been closed.
Protection against unintended vehicle unlocking
If you unlock the vehicle and do not open a door or the boot lid within the next
30 seconds, the vehicle will lock again automatically and the Safelock system
will be switched on.
Automatic locking/unlocking
All the doors and the luggage compartment lid are locked automatically once
the car reaches a speed of about 15 km/h.
If the ignition key is withdrawn, the car is then automatically unlocked again. It
is also possible for the driver to unlock the car by pressing the central locking
button.
The vehicle doors can be unlocked and opened at any time by pulling once on
the door opening lever.WARNING■ Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. These individuals
might not be able to exit the vehicle by themselves or to help themselves.
Can be fatal at very high or very low temperatures!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
