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 ⇒.

88Indicator for open doors or tailgate*
o
This warning lamp lights up if one of the doors or the tailgate
is open.The warning light
o should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off
approx. 15 seconds after the vehicle is locked.
Electromechanical steering*

For vehicles with power steering, the level of steering assistance depends on
the vehicle’s speed and on the steering angle.
The warning lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes off after a distance of approx. 50 m.
There is a fault in the electromechanical steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. The warning lamp may
appear in two different colours to indicate faults. If it lights yellow, this indi-
cates a minor fault. If it lights red, seek workshop assistance immediately, as
the steering assistance is not working; in this case you should not keep
driving. Stop the vehicle and seek technical assistance. The power steering
does not work if the battery is flat or if the engine is off (for example, for
towing). You should take into account that you will need considerably more
power than normal to steer the vehicle if the power steering is not working
correctly or at all.
For those vehicles fitted with ESP* the function “Recommended steering
manoeuvre” is included. See ⇒page 187.

This programme includes the ABS, EDL and TCS. This also includes the brake
assist system (BAS), automatic cleaning of the brake discs and the trailer
stability programme (TSP).
The warning lamp
 has the following functions:
•It flashes when the TCS/ESP is activated when driving.•It will light up continuously if there is a malfunction in the ESP.•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
