aked by the normal brake system. Visit a
specialist garage as quickly as possible and
adjust your style of driving appropriately as
you will not know how great the damage is. Further information about ABS
⇒page 167, “Antilock brake system (ABS)”.
A fault in the entire brake system If the ABS warning light
comes on together with the brake system warning light
(handbrake must be released), there is a fa

WARNING
•
If the brake system warning light
comes on together with the ABS
warning light
stop the vehicle immediately and check the brake fluid level in
the reservoir
⇒page 209, “Brake fluid”. If the fluid level has dropped below the
MIN marking, do not drive any further - risk of accident! Obtain professional assistance.•
Pay attention to the following instruct
ions before checking the brake fluid
level and opening the bonnet
⇒page 204, “Working in the engine compart-
ment”.
•
If the brake fluid is at the correct leve
l, the ABS control function has failed.
The rear wheels may then block very rapi
dly when braking. In certain circum-
stances, this can result in the rear end of the car breaking away - risk of skid-ding! Drive carefully to the nearest sp
ecialist garage and have the fault
rectified.Seat belt warning light
The warning light
comes on after the ignition is sw
itched on as a reminder for the

the driver or front passenger, a permanent
warning signal sounds at vehicle speeds gr
eater than 20 km/h and simultaneously the
warning light
flashes.
If the seat belt is not fastened by the dr
iver or front passenger during the next 90
seconds, the warning signal is deactivated and the warning light
lights up perma-
nently. Further information on the seat belts

indicator light in the driver door flashes for
about 2 seconds fast, goes out and starts to
flash slowly after about 30 seconds. If the indicator light first of all flashes fast for about 2 seconds, afterwards lights up for about 30 seconds and then flashes slowly, there is a fault in the system of the central locking or the interior monitor*

WARNING
Locking the doors prevents
involuntary opening in an exceptional situation (an
accident). Locked doors prevent unwanted
entry into the vehicle from outside,
for example at road crossings. Locked do
ors do, however, make it more difficult
for rescuers to get into the vehicle
in an emergency - danger to life!

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.

Safe securingThe central locking system is equipped with a
safe securing
6) system. Locking the
vehicle from the outside causes
the door locks to be automatically blocked. It is not
possible to open the doors with the door ha
ndle either from the inside or from the
outside. This acts as
an effective deterrent for attemp
ts to break into your vehicle.
You can deactivate the safe securing sy
stem by locking twice within 2°seconds.
If the safe securing system is not operating, the warning light in the driver door flashes for about 2 seconds fast, goes out and starts to flash slowly again after about 30°seconds. The safe securing system is again activate
d the next time the vehicle is unlocked and
locked again. If the vehicle is locked and the safe securi
ng system is deactiva
ted, you can open the
vehicle from the inside by pulling on the door opening lever. The door is unlocked and opened at the same time.6)Only valid for some countries.WARNING (continued)
