Airbag system
30Monitoring of airbag and belt tension device system
Both the airbag and belt tension device systems operation is constantly
monitored electronically. Each time th e ignition is switched on, the warning
lamp
lights for several seconds and the display in the instrument panel*
shows AIRBAG / TENSIONER .
The system must be checked when the warning lamp
:
•
does not light up when the ignition is switched on,
•
after the ignition is switched on, it turns off after 4 seconds,
•
it turns off and then lights up again after the ignition is switched on,
•
lights up or flashes while the car is moving.
In the event of a malfunction, the warning lamp remains on continuously. In
addition, depending on the malfunctio n, a fault message appears in the
display of the combi-instrument for approx. 10 seconds and a short acoustic
signal is given. In this event, you should have a qualified workshop check the
system immediately.
If any of the airbags are de-activated by the Authorised Service Centre, the
indicator lights for several seconds more after the veri fication and will turn off
if there is no fault.
WARNING
•
If there is a malfunction, the air bag and belt tension device system
cannot properly perform its protective function.
•
If a malfunction occured, have the system checked immediately by a
qualified workshop. Otherwise, in the event of an accident, the airbag
system and belt tension devices may no t be triggered, or may not be trig-
gered correctly.
Repairs, maintenance and disposal of the airbagsThe parts of the airbag system are installed in various places in your vehicle.
If you work on the airbag system or remove and fit parts of the system when
performing other repair work, parts of the airbag system may be damaged.
The consequence may be that, in the event of an accident, the airbag inflates
incorrectly or does not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are scrapped . The specialist workshops and the
Vehicle disposal centres are familiar with these requirements.
WARNING
•
If repairs are not carried out by a professional, or if the airbags are used
incorrectly, the risk of severe or fatal injuries is increased. The airbags may
fail to inflate, or could inflate in the wrong circumstances.
•
Do not cover or stick anything on the steering wheel hub or the soft
plastic surface of the airbag unit on the passenger side of the dashboard,
and do not obstruct or modify them in any way.
•
It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units.
•
To clean the steering wheel or dash panel, you may use only a dry or a
water-moistened cloth. Never clean the dash panel and the airbag module
surface with cleansers containing solvents. Solvents cause the surface to
become porous. If the airbag trigger ed, disintegrating plastic parts could
cause substantial injuries.
•
Never attempt to repair, adjust, remove or install parts of the airbag
system.
•
Any work on the airbag system or re moval and installation of the airbag
components for other repairs (such as repairs to the steering wheel) should
be performed only by a qualified workshop. Qualified workshops have the
necessary tools, repair information and qualified personnel.

The yellow warning
lamp remains on if the system is faulty or if
the pressure is too low in at least one tyre. In the event of a system
fault, the letters TPMS are displayed in the centre of the instrument
panel ⇒page 66, fig. 45. In case the tyre pressure drops rapidly,
the message ⇒page 66, fig. 46 is shown on the central display
of the instrument panel. If the pressure loss is slowly, the message ⇒ page 66, fig. 46 is shown on the central display of the isntru-
ment panel. The message does not show the tyre affected. Should
any of these warnings be displayed:
– Stop the engine.
– Check the tyres. Although the warning corresponds to just one tyre, you should also check the others.
– Correct the tyre pressure ⇒page 228.
For more detailed information on the tyre pressure monitoring system, please
refer to ⇒page 227.Cruise control system*
The indicator lamp
on the instrument panel lights up when the cruise
control system is operating.
Trailer indicators*
This indicator lamp flashes when the indicators are operating
while towing a caravan or trailer.The indicator lamp
flashes when the indicators are operated if a trailer is
correctly coupled to the vehicle.
Where a turn signal lamp does not work, either on the trailer or on the towing
vehicle, the indicator lamp will not flash.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the integrated elec-
tronic differential lock (EDL).The warning lamp
lights up for a few seconds when the ignition is
switched on and while the engine is being started. The lamp goes out again
after the system has run through an automatic test sequence.
There is a fault in the ABS if:
•
the warning lamp does not light up when the ignition is switched on,
•
The warning lamp does not go out again after a few seconds.
•
The warning lamp lights up when the vehicle is moving.
The vehicle can still brake in the normal way (except that the ABS control func-
tion is out of action). Please take the vehicle to a specialist garage as soon as
possible. For further information on the ABS ⇒page 176.
If a malfunction should occur in the ABS, the ESP warning lamp will also light
up.

68Entire brake system fault
If the ABS warning lamp
lights up together with the brake warning lamp
⇒ page 70 (with the handbrake released), this indicates not only a fault
in the ABS function, but probably also a malfunction in the main brake system
as well ⇒ .
The symbol
will light up in the instrument panel if a fault occurs in the
brake system . Please refer to ⇒ page 77.
Electronic differential lock (EDL) fault
The EDL works in conjunction with the ABS. The ABS indicator lamp will light
up
to indicate an EDL fault. Please take the vehicle to a specialist garage
as soon as possible. For further information on the EDL ⇒page 177.WARNING
•
Before opening the bonnet and checki ng the brake fluid level, observe
the warning information in ⇒ page 213, “Work in the engine compart-
ment”.
•
If the brake warning lamp
should light up together with the ABS
warning lamp
, stop the vehicle immediately and check the brake fluid
level in the reservoir. If the fluid level has dropped below the "MIN" mark
you must not drive on otherwise ther e may be an increased accident risk.
Obtain technical assistance.
•
If the brake fluid level is correct, the fault in the brake system may have
been caused by a fault in the ABS control function. As a result, the rear
wheels can lock relatively easily when braking. Under certain circum-
stances, the rear of the vehicle could suddenly sway from side to side, with
the subsequent danger of skidding. Drive carefully to the nearest specialist
garage and have the fault rectified.
Seat belt warning lamp*
The warning lamp acts as a reminder to the driver to fasten
the seat belt.After switching on the ignition, the warning lamp
will remain lit until the
driver and front passenger (if applicable) have fastened their seat belts.
When the vehicle has reached a certain speed, you will also hear a warning
signal and the warning light will flash.
For further information on the seat belts, see ⇒page 22.
Indicators and hazard warning lights
Depending on which turn signal is operated, either the left
or right
indi-
cator lamp flashes. Both indicator lamp s will flash when the hazard warning
lights are switched on.
If one turn signal fails, the indicator lamp will start flashing twice as fast as
normal.
This does not apply when towing a trailer. Where a turn signal lamp does not
work, either on the trailer or on the towing vehicle, the indicator lamp will not
flash. For further informatio n on the indicators, see ⇒page 119.
Electronic stabilisation programme
This warning lamp monitors the electronic stabilisation
program (ESP).The warning lamp
has the following functions:

•
It will start flashing to indicate that ESP is counteracting an unstable
driving condition.
•
It lights up when the ignition is switched on for approx. 2 seconds while
the function is checked.
•
The warning lamp will light up if there is a malfunction in the ESP.
•
It will light up after the battery has been disconnected.
•
The warning lamp will light up if the ESP is switched off.
•
It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp lights up and stays on after the engine is started, this
may mean that the control system has temporarily switched off the ESP. In this
case the ESP can be reactivated by switching the ignition off and then on
again. After this the warning lamp should go out to show that the system is
fully functional.
The warning lamp will light up when the ignition is switched on if the battery
has been disconnected and then reconnected. It should go out again after
driving a short distance if the steering wheel is turned slightly.
For further information on the ESP, see ⇒ page 177.
Alternator
The warning lamp signals a fault in the alternator or in the
vehicle's electrical system.The warning lamp
lights up when the ignition is switched on. It should
switch off after the engine has started.
If the warning lamp lights up when you are driving, you can normally
continue as far as the nearest specialist garage. However, given that the
battery will be running down, any electr ical consumption not absolutely vital
should be switched off.
Caution
If the coolant warning lamp
in the instrument panel lig h t s u p a s w e l l a s t h e
alternator waning lamp while driving ⇒page 77, stop the vehicle immedi-
ately and switch off the engine. In this case the coolant pump is no longer
being driven, and there is a risk of engine damage.
Main beam headlights
The indicator lamp
lights up when the main beams are on or when the
headlight flasher is operated.
For further information on the main beam headlights, see ⇒page 119.
Engine management
This warning lamp monitors the engine management system
for petrol engines.The warning lamp
(Electronic Power Control) li ghts up while the function
is being checked.
Note
If the warning lamp lights up while the vehicle is moving, this indicates a fault
in the engine management system. The vehicle must be taken immediately to
a specialist garage to have the engine serviced.

Bulb monitor
The bulb monitor checks whether the lights on the vehicle are
working.If a defective bulb is detected, or if one of the lights has failed for any reason,
the bulb monitor symbol
will appear in the display together with an addi-
tional message (which goes out after 5 sec onds). For instance, if the rear left
turn signal is not working, the display in the instrument panel will show the
following message:
Left rear turn signal
The message disappears after 5 seconds. Press the CHECK button briefly if
you wish to call up the message again.
If the display indicates that one of the lights is not working, this can have a
number of causes:
•
Bulb failure ⇒page 249.
•
A “blown” fuse ⇒page 247, “Changing fuses”.
•
Faulty electrical wiring.
Have the components replaced or the wiring repaired as necessary by a
specialist garage.
WARNING
•
Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
The high voltage element of gas discharge lamps* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
Speed warning
Introduction
The speed warning function can help prevent you exceeding
a particular pre-set maximum speed.The speed warning function will warn the driver if a pre-set maximum speed
is exceeded. The system gives an audible warning signal if the set speed is
exceeded by about 10 km/h. A warning symbol will also appear in the display
⇒ fig. 55 .
The speed warning function has two different warning speeds, which operate
independently and serve slightly different purposes:
Speed limit warning 1
With speed limit warning 1, the maximum speed can be changed while
driving. The speed limit that has been set remains stored until the ignition is
switched off, or until it is changed or cleared.

Automatic (sensor-controlled) headlights*
If you set the switch to “AUTO”, the headlights will come on
and switch off automatically according to the ambient light
level.The sensor-controlled dipped beam headlights have the same prop-
erties as the main beam headlights ⇒page 112.
Enabling the headlights
– Turn the light switch ⇒ fig. 84 to the AUTO position.
Disabling the headlights
– Turn the light switch to position O.The symbol on the switch lights up when the switch is in the AUTO position.
The dipped beams, side lights, rear li ghts and number plate lights come on
together when the headlights are switched on automatically. When you are using the automatic headlights, you can also operate the main
beam headlights, however, please note the following: If you enable the main
beam headlights while using the automatic headlights function
during the
day (e.g. when driving through a tunnel), but do not disable them again, only
the dipped beam headlights will come on the next time the lights are auto-
matically switched on. To be able to use the main beam headlights again, you
must first pull the main beam lever back to the "off" position and then push
it forward again to "on".
The side lights, headlights, fog lights and rear fog light can still be switched
on manually in the normal way by using the light switch ⇒page 112.
The mirror inside the vehicle is fitted with sensors that measure the ambient
light. The headlights will be switched on automatically if the available light
drops below a preset value (for instance when driving through a tunnel, etc.).
The headlights switch off again automatically when the light level increases
⇒ .
WARNING
•
The automatic headlights are only intended to assist the driver. The
driver must always ensure that the headlights are used when required and
may have to switch them on manually when the light conditions or visibility
are poor. The light sensors are, for example, unable to detect rain and fog
- you should therefore always switch on the headlights
in these condi-
tions and when driving after dark.
•
Observe all relevant legal requirements when using the signalling and
lighting systems described here.Note
•
When the automatic headlights have been enabled, the dipped-beam
headlights will go out when the ignition is switched off and the side lights will
go out when the key is removed.
