Main beam headlights 
This warning 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.
Further information  ⇒page 116.
Soot accumulation in the diesel engine particulate filter 
If the indicator lights 
 you may help the filter clear itself by driving in the 
appropriate manner.
To do this, drive about 15 minutes in 4th or 5th gear (automatic gearbox: S 
gear range) at a speed of 60 km/h, with the engine running at approximately 
2000 rpm. In this way, the pollen buil d up in the filter is burned. When 
cleaning is successful, the indicator turns off.
If the indicator 
 is not deactivated, bring the vehicle to a specialised work-
shop 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. Failure to comply could result in fire.
Anti-lock brake system (ABS) 
 
A warning lamp system monitors the ABS.
The warning lamp 
 should light up for a few seconds when the ignition is 
switched on. It goes out again after th e 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 be braked in the normal way (except that the ABS control 
function will not function). Please take the vehicle to a qualified workshop as 
soon as possible. For further information on the ABS see the  ⇒page 183.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp 
 lights up together with the brake warning lamp 
, 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 213, “Working in the engine compartment”.
•
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  ⇒page 226, “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

Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more 
wheels, the button  ⇒page 78, fig. 49  must be kept pressed while the igni-
tion is on until an acoustic signal is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or 
heavy load), the tire pressure must be increased to the recommended value 
for a full load (see the sticker on the inside of the fuel flap). If the tyre monitor 
system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure monitor indicator 
 lights up
If the tyre pressure of one or more wheels is much lower than the value set by 
the driver, then the tyre co ntrol warning lamp lights up  ⇒.
The tyre pressure monitor indicator  flashes
If the tyre pressure indicator flashes, this indicates a fault. Go to the nearest 
specialist workshop.
WARNING
•
When the tyre pressure indicator l ights, reduce speed immediately and 
avoid any sudden manoeuvre or braking. Stop when possible, and check 
the tyre pressure and status.
•
The driver is responsible for correct tyre pressure. For this reason, tyre 
pressure must be regularly checked.
•
Under certain circumstances (for exam ple, in a sports situation, in 
winter conditions or on a dirt track) the tyre monitor indicator may light or 
function incorrectly.Note
If the battery is disconne cted, the yellow indicator 
 lights up after turning 
the ignition on. This should  turn off after a brief journey.

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. 74   .
Those vehicles fitted with xenon gas discharge headlights are fitted with an 
automatic headlight range system.
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 traffi c 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 wh eel down   from the basic setting 0.Dynamic headlight range control
Vehicles with 
gas discharge lamps  (“xenon lamps”) 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 lamps do not have headlight range control.
Self directional headlights*
When driving around bends, the headlights will light the 
most important areas of the road.Dynamic curve lights (AFS)
The  dynamic curve lights  only operate if the vehicle is travelling at more than 
10 km/h and the dipped headlamps are on. When taking a bend, the road is 
illuminated better with directional gas discharge lamps than with conven-
tional fixed headlamps.
