If the warning light flashes again after the engine has started, there is a
system error.
Seek help from a specialist garage.
The following reasons can explain the warning light
being illuminated.
› The vehicle is loaded on one side. Distribute loads as evenly as possible.
› The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
› Snow chains are mounted.
› A wheel has been changed.

roads) the warning light can be delayed or does not light up at all.
Note
If the vehicle's battery has been disconnected and reconnected, the warning
light comes on after switching on the ignition. If the indicator light does not
go out after moving a short distance, this means that there is an error in the
system. Seek help from a specialist garage.

Your car is equipped with a central locking system.
The central locking system allows you to lock and unlock all doors, the fuel fill-
er flap and boot lid at the same time.
Depending on the equipment configuration, the following is true after
unlocking
› The turn signal lights flash twice as confirmation that the vehicle has been
unlocked.
› The doors, the boot lid and the fuel filler flap are unlocked.
› The interior light operated via the door contact illuminates.
› The SafeLock system is switched off.
› The indicator light in the driver door stops flashing.
› The anti-theft alarm system is deactivated.
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
or anti-theft alarm system will be switched on. This function is intended to
prevent the car being unlocked unintentionally.
Depending on the equipment configuration, the following is true after
locking
› The turn signal lights flash once as confirmation that the vehicle has been
locked.
› The doors, the boot lid and the fuel filler flap are locked.
›The interior light operated via the door contact goes out.
› The SafeLock system is switched on.
› The indicator light in the driver door begins flashing.
› The anti-theft alarm system is activated.
If the doors or the boot lid remain open after the vehicle has been locked, the
turn signal lights do not flash until they have been closed.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. The children might,
for example, release the handbrake or take the vehicle out of gear. The ve-
hicle could then start to move – risk of injury and accidents! These individu-
als might also not be able to leave the vehicle on their own 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 battery must be replaced if the central locking or anti-theft alarm system
does react to the remote control at less than approx. 3 metres
away » page 210 .
■
When leaving the vehicle, always check if it is locked.
■
If the driver's door has been opened, the vehicle cannot be locked.
Note
In the event of an accident in which the airbags are deployed, the locked doors
are automatically unlocked in order to enable rescuers to gain access to the
vehicle.51Unlocking and opening
