Your car is equipped with a central locking system.
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.
Depending on the equipment configuration, the following applies after lock-
ing.
▶ The turn signal lights flash once as confirmation that the vehicle has been
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If the ignition key is withdrawn, the car is then automatically unlocked again.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-
nition lock.

The following applies after locking. ▶ Opening the doors and the boot lid from the outside is not possible.
▶ The doors can be unlocked and opened from the inside by a single pull on the
opening lever of the respective door.WARNINGDoors locked from the inside make it difficult for rescuers to get into the
vehicle in an emergency – risk to life!
Safe securing system
Read and observe
and on page 39 first.
As soon as the vehicle has been locked from the outside, the Safelock systemprevents the doors from being opened from the inside.
You will be informed that the safelock system has been activated after the ve-
hicle has been locked by means of the message

around 2 seconds in quick succession, afterwards it begins to flash evenly at
longer intervals.
Switching off
▶ The safelock can be switched off by locking twice within 2 seconds.
The indicator light in the driver door flashes for about 2 seconds fast, goes out
and starts to flash at longer intervals after about 30 seconds.
If the vehicle is locked and the safe securing system is switched off, the door
can be opened separately from the inside by a single pull on opening lever.
The Safelock system switches back on when the vehicle is locked.
WARNINGIf the car is locked and the safe securing system activated, no people must
remain in the car as it will then not be possible to either unlock a door or
