84Main beam headlights

The indicator lamp lights up when the main beams are on.The warning lamp
 is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒page 124.
Soot accumulation in the diesel engine particulate filter

If the warning lamp
 lights up you should help the filter clean itself by
driving in the appropriate manner.
To do this, drive about 15 minutes in fourth or fifth gear (automatic gearbox:
S gear range) at a speed of 60 km/h, with the engine running at approxi-
mately 2000 rpm. In this way, the pollen build up in the filter is burned. When
cleaning is successful, the indicator turns off.
If the warning lamp  does not turn off, or the three lamps turn on (partic-
ulate filter
, emission control system fault
 and glow plugs
D), take
the vehicle to a specialised workshop to repair the fault.
WARNING
•Always drive according to the road weather conditions, the terrain and
traffic. Driving recommendations should never lead to illegal manoeuvres
in surrounding traffic.•The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.
Anti-lock brake system (ABS)*
J
A warning lamp monitors the ABS.
The indicator lamp
J should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
•The warning lamp
J 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 be braked in the normal way, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒page 185.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp
J lights up together with the brake warning lamp
H, this indicates not only a fault in the ABS function, but also a possible fault
in the brake system ⇒.
WARNING
•Before opening the bonnet, read and observe the warnings on
⇒ page 221, “Working in the engine compartment”.•If the brake warning lamp
H should light up together with the ABS
warning lamp
J, stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒page 233, “Brake fluid”. If the fluid level has
dropped below the “MIN” mark you must not drive on. Risk of accident.
Obtain technical assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS system. This could cause the rear

Automatic lighting
If automatic headlight control is switched on, dipped beam headlights are
automatically switched on by a photosensor if you drive into a tunnel, for
example.
The rain sensor switches on the dipped beam headlights when the wind-
screen wipers have been operating continuously for a few seconds and it
switches the lights off when the continuous or intermittent wipe is switched
off for some minutes ⇒
page 129.
When the automatic dipped light control is connected but the dipped lights
are off, the warning lamp

lights up on the light control ⇒fig. 72 . If the
automatic control switches on the dipped lights, the instrument and control
lighting is also switched on.
WARNING
•Even if the automatic headlight control is switched on, the dipped
headlights will not be switched on with fog. Therefore, the dipped beam
must be switched on manually.Note
•For those vehicles with the automatic headlight system, when the key is
removed from the ignition, the acoustic signal will only sound if the light
control is in the position
 or  if the vehicle is not fitted with the coming
home function.

Instrument and switch lighting / Headlight range controlInstrument and switch lighting
When the headlights are switched on, the brightness of the instruments and
switch lighting can be regulated to suit your requirements by turning the
thumb wheel ⇒fig. 73 .
The instrument lighting (dials and needles), the centre console illumination
and the illumination of the displays are regulated by a photodiode incorpo-
rated in the instrument panel.
The instrument lighting (dials and needles) is switched on when the ignition
is on and the vehicle lights are off . The instrument lighting is dimmed auto-
matically as the daylight starts to fade. It goes out completely when the
ambient light level is very low. This function is intended to remind the driver
to switch on the dipped beam headlights in good time when light conditions
become poor.
Headlight range control
By using the electrical headlight range control, you can adjust the head-
light range to the load level that is being carried in the vehicle. This way, it is possible to avoid dazzling oncoming traffic more than necessary. At the same
time, by using the correct headlight settings, the driver has the best possible
lighting for the road ahead.
The headlights can only be adjusted when the dipped beam is switched on.
To lower the beam, turn the thumb wheel down from the basic setting
0.
Dynamic headlight range control
Vehicles with gas discharge bulbs (“xenon bulbs”) are equipped with
dynamic headlight range control . This means that the headlights will be
adjusted to suit the load level of the vehicle and “nodding movements” when
pulling off and braking are automatically compensated for.
Vehicles with gas discharge bulbs do not have headlight range control.
Adaptive headlights* (for driving round bends)
When driving around bends, the headlights will light the
most important areas of the road.

122Dynamic cornering lights (AFS)
The dynamic cornering lights only operate if the vehicle is travelling at more
than 10 km/h and the dipped headlights are on. When taking a bend, the
road is illuminated better with directional gas discharge bulbs than with
conventional fixed headlights.
A fault in the system is indicated via the flashing of the control lamp
 on the
instrument panel. At the same time, a text message with information or
instructions to perform necessary operations may appear on the instrument
panel display. Take the vehicle to a specialised workshop and have the fault
repaired.
If the warning lamp
 lights up on the instrument panel but all the bulbs are
operating correctly ⇒page 259, there may still be a fault in the dynamic
cornering light system (AFS). Take the vehicle to a specialised workshop and
have the fault repaired.
WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for the
correct use of lights in all situations. “Automatic headlight control” is
merely a system to support the driver. Where necessary, switch on the
lights manually using the light switch.Fog lights with cornering function*When the turn signal is switched on to turn or on very tight bends, the right
or left fog lamp automatically comes on to function as a cornering light. The
cornering light only operates if the dipped lights are on.
WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for the
correct use of lights in all situations. “Automatic headlight control” is
merely a system to support the driver. Where necessary, switch on the

The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving traffic.
