Soot accumulation in the diesel
engine particulate filter  If the control lamp
 lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h (37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp
 does not turn off, or the three
l amp

s turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Always drive according to the road weather
conditions, the terrain and traffic. Driving rec-
ommendations should never lead to illegal
manoeuvres in surrounding traffic.
● The diesel engine particulate filter may
reach extremely high temperatures; in this
case the vehicle should be parked so that it
does not enter into contact with highly flam-
mable materials underneath the vehicle. Oth-
erwise there is a risk of fire. Anti-lock brake system (ABS)* 
The warning lamp  lights up for a few sec-
onds when the ignition is switched on. It
goes out again after the system has run
through an automatic test sequence.

Operation
There is a fault in the ABS if:
● The warning lamp 
does not light up
when the ignition i
s switched on.
● The control lamp does not go out again af-
ter a few seconds.
● The control lamp lights up when the vehicle
is moving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi-
cle to a specialised workshop as soon as
possible. For further information on the ABS
see the ››› page 136
.
If a fault occurs in the ABS, the ESC* control
lamp will also light up.
Brake system fault
If the ABS warning lamp  lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ››› .
WARNING
● Before opening the bonnet, read and ob-
serve the warnings ››› page 163, Working in
the engine compartment.
● If the br

ake system 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 172, Brake fluid. If the brake fluid
l ev

el 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 wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Washer fluid* 
This warning lamp lights up to indicate that
the windscreen washer level is very low.
This serves as a reminder to fill up the reser-
voir at the earliest opportunity

SCREEN WASHER FLUID .
Alternator  This warning lamp signals a fault in the alter-
nator.The warning lamp

lights up when the igni-
tion i

s switched on. It should go out when the
engine has started running.
If the warning lamp 
lights up while driv-
ing, the alternator is no longer charging the
battery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment

Tyre pressure  Fig. 32
Centre console: tyre monitoring sys-
tem button. The tyre pressure monitoring system controls
tyre speed and the frequency spectrum of
each tyre.
The tyre monitoring lamp
1)
compares wheel
revolutions and with it, using the ESC, the
wheel diameter of each wheel. If the diame-
ter of a wheel changes, the tyre control lamp
 lights up. The wheel diameter 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 steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
Following the modification to tyre pressure or
after changing one or more wheels, the but-
ton ››› Fig. 32 must be pressed down while
the ignition i s
on until an audible warning is
heard and the warning lamp goes out.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
tyre pressure must be increased to the rec-
ommended 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 control lamp  lights up
If the tyre pressure of one or more wheels is
much lower than the value set by the driver,
the tyre control warning lamp lights up ››› .The tyre pressure control lamp
 flashes
If the ty

re pressure control lamp flashes, this
indicates a fault. Go to the nearest special-
ised workshop. WARNING
● When the tyre pressure monitoring lamp
lights up, reduce speed immediately and
avoid any sudden manoeuvre or braking.
Stop when possible, and check the tyre pres-
sure and status.
● The driver is responsible for maintaining
correct tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a sporty manner, in winter condi-
tions or on a dirt track) the tyre monitoring
lamp may light up or function incorrectly. Note
If the battery is disconnected, the yellow
warning lamp  lights up after turning the
ignition on.

This should turn off after a brief
journey. 1)

Indicator for open doors or boot*  This warning lamp lights up if one of the
doors 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 disappear approxi-
mately 15 seconds after the vehicle has been
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 dis-
tance of approx. 50 m.
There is a fault in the electromechanical
steering system if the lamp does not go out
or lights up while the vehicle is in motion.
The warning lamp may appear in two differ-
ent colours to indicate faults. If the light is
yellow, it indicates a minor fault. If the light is
red, seek assistance from a specialised work-
shop immediately, as the power steering 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 (e.g.
for towing). You should take into account that
you will need considerably more power than
normal to steer the vehicle if the power steer-
ing is not working correctly or at all.
For those vehicles fitted with ESC*, the
“Steering manoeuvre recommendation”

Operation
Safety

Operation
The warning lamp 
has the following
f
unctions:
● It flashes whilst driving when the ASR/ESC
is activated.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light will also come on if a fault
should occur in the ABS.
If the ESC control lamp 
stays on after the
engine is started, this may mean that the
control system has temporarily switched off
the ESC. In this case the ESC can be reactiva-
ted by switching the ignition off and then on
again. If the control 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 is disconnected
when pressing the  switch.
Differential lock fault (EDL)* The EDL operates along with the ABS in vehi-
cles equipped with Electronic Stability Con-
trol (ESC)*.
A malfunction in the EDL is indicated by the
ABS control lamp
. Take the vehicle to a specialised workshop as soon as possible.
For further information on the EDL see
››› page 135, Electronic differential lock
(EDL)* .
T r

action control system (ASR)*  /  The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
There are two warning lamps for the traction
control system:
 and . Both warning lamps
light up together when the ignition is switch-
ed on and should turn off after approximately
2 seconds. This is the time taken for the func-
tion check.
The  lamp has the following function:
● It flashes when the ASR is working if the ve-
hicle is moving.
If the system is deactivated or if it has any
fault, the warning lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ›››
page 137. The
 lamp provides information about the
di

sconnection status of the system:
● It stays lit when the ASR is disconnected
when pressing the ASR OFF switch.
By pressing it again, the ASR function is reac-
tivated and the warning lamp switched off.
