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 198.
•
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 211, “Brake fluid”. If the fluid level has
dropped below the “MIN” mark you must not drive on. Risk of accident.

Tips and Maintenance
Te c h n i c a l D a t a
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when the vehicle is acceleratingThe warning lamp lights up when the ignition is switched on and should turn
off after about 2 seconds.
When the TCS is operating while driving, the warning lamp flashes. If the
system is deactivated or if there is any fault in the same, the warning lamp will
remain lit.
It will also come on if a fault should occur in the ABS because the TCS oper-
ates in conjunction with the ABS. For further information see ⇒page 169.Soot accumulation in the dies el engine particulate filter*

if the symbol
 lights, soot has built up in the diesel engine particulate filter
due to continuous short trips. In this case, drive the vehicle at a constant
speed of at least 60 km/h (with an engine speed of about 1400 rpm) for
about 10 minutes. The increase in temperature generated may burn the accu-
mulated soot in the filter.
If the symbol  is not deactivated, bring the vehicle to a specialized work-
shop to repair the fault.
For more information on the diesel particulate filter ⇒page 175.
WARNING
•
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.
Caution
Vehicles equipped with a diesel engine particulate filter must not be refuelled
using biodiesel (RME), given that the fuel system may be damaged.Alternator


This warning lamp signals a fault in the alternator.
The warning lamp
 lights up when the ignition is switched on. It should go
out when the engine has started running.
If the warning lamp  lights up while driving, th e alternator is no longer
charging the battery. You should immediately drive to the nearest qualified
workshop.
You should avoid using electrical equipment that is not absolutely necessary
because this will drain the battery.
If the indicator flashes, the voltage is insufficient for normal vehicle
operation.

It will light up continuously 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. If the warning lamp goes out, this means the system is fully
functional.
Operating the foot brake

The footbrake must be depressed when this warning lamp lights up. This is
necessary when the automatic gearbox* selector lever is moved out of the
positions P or N.Power steering system*

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 when the engine has started running.
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 electromechanica l steering system if the lamp does not
go out or light up, wh ils
t the vehicle is in motion. The indicator may appear in
two different colours to indicate faults. If it lights yellow, this indicates a
minor fault. If it lights red, seek wo rkshop assistance immediately, if no
assistance is available stop 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
steering assistance is reduced
or has failed completely.
Brake pad wear indicator*

As the brake pad wear indicator only monitors the front brake pads, it is advis-
able to have the rear brake pads inspected at the same time.
The information text displayed in the instrument panel display is
