Airbag system
Monitoring the airbag system
The warning light
comes on for a few seconds when the ignition is switched on.
There is a fault in the system if the warning light does not go out or flashes while driving
. This also applies if the warning light does not come on when the ignition is
switched on.
The following text will be displayed in the information display*:
Error: Airbag
The functionality of the airbag system is also monitored electronically when one airbag
has been switched off.
The following situation applies if the fr ont, side and head airbags or belt
tensioner have been switched off using the vehicle system tester:
The warning light
lights up for 4 seconds after switching on the ignition and then
flashes again for 12 seconds in intervals of 2 seconds.
The following text will be displayed in the information display*:
Airbag/belt tensioner deactivated
The following situation applies if the ai rbag has been switched off using the
switch for the airbag* in the storage compartment:
the warning light
comes on for 4 seconds after the ignition has been switched
on,
switching off the airbag is indicated in the middle of the dash panel by the lighting
up of the indicator light
(airbag switched off) page 157.
WARNING
Have the airbag system checked immediat ely by a specialist garage if a fault
exists. Otherwise, there is a risk of the airbag not being activated in the event of
an accident.Control system for exhaust
The warning light
comes on after the ignition has been switched on. If the warning light does not go out after starti
ng the engine or it lights up when driving,
a fault exists in an exhaust relevant co mponent. The engine management system
selects an emergency programme which enables you to drive to the nearest specialist
garage by adopting a ge ntle style of driving.
Electromechanical power steering
The warning light
comes on for a few seconds when the ignition is switched on.
If the warning light after switching on the ignition or when driving lights up continu-
ously, a fault exists in the electromechanical power steering.
If the yellow warning light lights up
, this indicates a partial failure of the power
steering and the steering forces can be greater.
If the red warning light lights up
, this indicates a complete failure of the power
steering and the steering assist has failed (significantly higher steering forces).
Further information page 172.
WARNING
Contact your specialist garage if the power steering is defective.
Note
If the yellow warning light
goes out after starting the engine again and a short
drive, it is not necessary to visit a specialist garage.
If the battery has been di sconnected and reconnected, the yellow warning light
comes on after switching on the ignition. Th e warning light must go out after driving a
short distance.
Engine oil pressure
The warning light comes on for a few seconds
4) when the ignition is switched on.
4)The warning light on vehicles fitted with information display does not come on after switch-
ing the ignition on, but only if a fault exists or the engine oil level is too low.

Selector lever lock*
If the green warning light
lights up, operate the brake pedal. This is necessary, in
order to be able to move the selector lever out of the position P or N.
Further information about the selector lever lock page 116.
Tyre inflation pressure*
The warning light
lights up, if there is a substantia l drop in inflation pressure in one
of the tyres. Reduce the speed and check or correct as soon as possible the inflation
pressure in the tyres page 208.
If the warning light flashes, there is a system fault. Visit the nearest specialist garage and
have the fault rectified.
Further information about the tyre pressure monitoring system page 172.
WARNING
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvr es. Please stop the vehicle without
delay at the nearest possible stop and in spect the tyres and their inflation pres-
sures.
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light
can be delayed or does not light up at all.
Note
If the battery has been disconnected, the warning light
comes on after switching on
the ignition. The warning light must go out after driving a short distance.
Antilock brake system (ABS)
The warning light
shows the functionality of the ABS.
The warning light comes on for a few seconds after the ignition has been switched on
or when starting the engine. The warning light goes out after an automatic check
sequence has been completed. A fault in the ABS
The system is not functioning properly if the ABS warning light
does not go out
within a few seconds after switching on the igni tion, does not light up at all or lights up
while driving. The vehicle will only be br aked by the normal brake system. Visit a
specialist garage immediately and adjust your style of driving appropriately as you will
not know how great the damage is.
Further information about ABS page 171, “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 fault not only in the ABS but also in another
part of the brake system .
WARNING
If the brake system warning light
comes on together with the ABS
warning light
stop the vehicle immediately an d check the brake fluid level in
the reservoir page 202, “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 instructions before checking the brake fluid
level and opening the bonnet page 197, “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 specialist garage and have the fault
rectified.
Bonnet
The warning light
comes on if the bonnet is unlocked. If the bonnet unlocks while
driving, the warning light lights up
and as a warning an audible signal sounds.
The warning light comes on even when the ig nition is switched off. The warning light
lights up for a maximum of 5 minutes.

Switching on side lights– Turn the light switch into position
.
Switching on the low beam and main beam– Turn the light switch into position
.
– Press the main beam lever forward in order to switch on the main beam page 57, fig. 43 .
Switching off lights (except daylight driving lights)– Turn the light switch into position°0.
Low beam comes on only if the ignition is switched on. After switching off the ignition,
the low beam is switched off automatica lly and only the side lights come on.
On vehicles with separate ligh ts* for daylight driving lights in the fog lights or in the
front bumper, the low beam does not light up when the light switch is in position 0
even if the ignition is switched on. On models fitted with
right-hand steering the position of certain switches differs
from that shown in fig. 37 . The symbols which mark the switch positions are iden-
tical, however.
WARNING
Never drive with side lights on - risk of accident! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by other
oncoming traffic. In this case, always switch on the low beam when it is dark or
if visibility is poor.
Note
An audible warning will sound if you wi thdraw the ignition key and open the
driver's door when the vehicle lights are still on.
The acoustic warning signal is switched off over the door contact when the driver's
door is closed (ignition off). The vehicle can be parked with the side lights on.
If the car is parked for a lengthy period, we recommend switching off all lights, or
leaving only the parking lights switched on.
The switching on of the described lights should only be undertaken in accordance
with the legal requirements.
If a fault occurs in the light switch , the low beam comes on automatically
In the event of cool or humid weather cond itions, the headlights can be misted up
from inside.
The temperature difference between interior and external area of the headlight
lenses is decisive.
When the driving lights are switched on, the light outlet surfaces are free from
mist after a short period. The headlight lenses can possibly mist up at the border
areas.
It also concerns reverse light and turn signal lights.
This mist has no influence on th e life of the lighting system.

Lights & Vision
On vehicles with separate ligh ts* for daylight driving lights in the fog lights or in the
front bumper, the parking lights and the lice nce plate light do not come on when acti-
vating the function daylight drivin g lights (neither front nor rear).
If the vehicle is not equipped with separate lights* for daylight driving lights, the
combination of the low beam, the parking ligh ts (front and rear) including the licence
plate light is used as daylight driving lights.
In some countries, the na tional legal provisions require that the rear parking lights also
come on together with the separate lights* for daylight driving lights when activating
the function daylight driving lights.
When the daylight driving lights are switch ed on, the illumination of the instrument
cluster is switched off, however, it is switched on in the position
when it is dark
and the low beam shines with full br ightness (100% of the performance).

If the light comes on automatically, the side lights and low beam as well as licence plate
light light up at the same time.
If the automatic light control* is switched on , the light is regulated with the light sensor
in the rear mirror holder. If the light intensity drops below the set value, e.g when
driving during the day into a tunnel, the lo w beam and the side lights as well as the
licence plate light come on automatically. If the light intensity increases again, the
lights switch off automatically.
