Main 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
