To do this, drive about 15 minutes in fourth or fifth gear (automatic gear-
box: S gear range) at a speed of 60 km/h, with the engine running at ap-
proximately 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 ), 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 ma-
noeuvres in surrounding traffic.
● The diesel engine particulate filter may reach extremely high temper-
atures; 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)*
A warning lamp monitors the ABS.
The indicator lamp should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automat-
ic 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, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒ page 194. If a fault occurs in the ABS, the ESC* (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 230, 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 243, Brake fluid. If the fluid level has drop-
ped below the “MIN” mark you must not drive on. Risk of accident. Ob-
tain 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 wheels to lock quickly when you brake. This could cause the rear to
break away. Risk of skidding. Stop the vehicle and seek technical assis-
tance.
Washer fluid
This warning lamp lights up to indicate that the windscreen
washer level is too low. This serves as a reminder to fill up the reservoir at the earliest opportunity

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, the alternator is no longer
charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery.
Worn brake pads
If the symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop. Tyre pressure
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.
Fig. 52 Centre console:

ton
The tyre warning lamp 2)
compares wheel revolutions and with this informa-
tion, the diameter of each wheel using the ESC (ESP) sensors. If the diame-
ter of a wheel changes, the tyre warning lamp lights up. The wheel diam-
eter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains.

ing, the brake fluid level ⇒ page 243, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.
Handbrake
This lamp lights up when the handbrake is applied. If you drive faster than 6 km/h with the handbrake on, the following mes-
sage will appear on the instrument panel display 1)
: HANDBRAKE ON. You will
also hear an acoustic warning signal ⇒ page 185. Engine oil pressure
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil ⇒ page 233.
The instrument panel displays the following message 1)
: STOP ENGINE OIL
PRESSURE INSTRUCTION MANUAL .
If the symbol flashes although the oil level is correct, do not drive on. The
engine must not even run at idle speed. Obtain technical assistance.
Checking the oil level
If the warning lamp is yellow the engine oil level should be checked as
soon as possible. Top up the oil ⇒ page 236 at the next opportunity.
Oil level sensor faulty*
If the yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel.

Indicator for open doors or tailgate*
This warning lamp lights up if one of the doors or the tail-
gate is open.
The warning light should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off ap-
prox. 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 en-
gine running. The warning light only goes off after a distance of approx.
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
indicates a minor fault. If it lights red, seek workshop assistance immedi-
ately, 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 exam-
ple, for towing). You should take into account that you will need considera-
bly more power than normal to steer the vehicle if the power steering is not
working correctly or at all. For those vehicles fitted with ESC (ESP)* the function “Recommended steer-
ing manoeuvre” is included. See
⇒ page 196.

Electronic Stability Control ESC (ESP) * /
There are two control lamps for the electronic stability con-
trol. The lamp provides information concerning the func-
tion and the provides information on the disconnection
status
Both lamps come on together when the ignition is switched on and should
go out after approx. 2 seconds, which is how long the function check lasts.
This programme includes the ABS, EDL and ASR (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 ASR (TCS)/ESC (ESP) is activated when driving.
● It will light up continuously if there is a malfunction in the ESC (ESP).
● The ESC (ESP) lamp will also come on if a fault should occur in the ABS
because the ESC (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 ESC (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.
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR (TCS) is disconnected after pressing the
switch. Differential lock fault (EDL)*EDL operates along with the ABS in vehicles equipped with
the Electronic Stability Control ESC (ESP)*
A malfunction in the EDL is indicated by the ABS warning lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 197, Electronic differential lock (EDL)*.

The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system: and . Both
lamps come on together when the ignition is switched on and should go out
after approx. 2 seconds, which is how long the function check lasts.
The lamp has the following function:
● It flashes when the ASR (TCS) is activated while driving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The ASR (TCS) lamp will also come on if a fault should occur in the
ABS because the ASR (TCS) operates in conjunction with the ABS. For fur-
ther information, see ⇒ page 194, Brakes
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR (TCS) is disconnected after pressing the OFF
switch.
By pressing again, the ASR (TCS) function is reactivated and the warning
lamp switched off.
