Engine oil level correct
If the symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even
at idle speed .
Note
The oil pressure warning lamp is not an indicator for the oil level. The oil
level should therefore be checked regularly, preferably every time you fill
the tank.

Cockpit
Yellow symbols are used to indicate a Priority 2 fault (warning).
Yellow symbols are accompanied by one warning buzzer. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time.
Brake light failure
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right).
Fuel level low
When this symbol comes on for the first time, there are about 8 to 10 li-
tres of fuel left in the tank. You should fill up as soon as possible
⇒ page 224.
Engine speed governing
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp
on the instrument panel will light up. The engine speed will be governed to
the speed displayed in the driver information system. Please ensure that
the engine speed does not exceed the speed shown (for example, when
changing down a gear).
Take the vehicle to a specialised workshop immediately to have the fault re-
paired. Checking the engine oil level
If the symbol lights up, please check the engine oil level as soon as pos-
sible ⇒ page 231. Top up the oil at the next opportunity ⇒ page 232.
Engine oil sensor defective*
If the symbol lights up, take the vehicle to a specialised workshop and
have the oil level sensor checked. Until then it is advisable to check the oil
level every time you fill up with fuel ⇒ page 231.
Diesel particulate filter obstructed
If the symbol lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes
in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h,
with the engine running at approximately 2,000 rpm. The increase in tem-
perature will burn off any soot in the filter. When cleaning is successful, the
symbol switches off.
If the symbol does not turn off, or the three lamps turn on (particulate
filter , emission control system fault and heaters ), take the vehicle
to a specialised workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 196.
WARNING
It is essential that you adjust your speed to suit the weather, road, ter-
rain and traffic conditions. The recommended driving speed must never
lead to the driver disregarding the traffic regulations.

Photosensor/rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol lights up, this means that the photosensor/rain sensor is
not working. For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with
the light switch. If the rain sensor is faulty, the functions operated via the
windscreen wiper lever will still be available. You should have the photosen-
sor/rain sensor checked by a specialised workshop as soon as possible.
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.
Speed warning 1
If the symbol lights up, this means you are exceeding the speed that has
been pre-set with the speed warning function. You should reduce your
speed accordingly ⇒ page 83.
Headlight range control faulty
This symbol indicates a malfunction in the dynamic headlight range con-
trol. Take the vehicle to a specialised workshop to have the dynamic head-
light range control function repaired. Adaptive headlights* faulty
Adaptive headlights faulty
This symbol indicates that the adaptive headlight system is faulty. Take
the vehicle to a specialised workshop to have the headlights or the adap-
tive headlight control unit repaired.
Washer fluid level low
If the symbol lights up, top up the fluid for the windscreen washer and
headlight washer system* ⇒ page 235.
Speed warning 2
If the symbol lights up, this means you are exceeding the speed that has
been pre-set. You should reduce your speed accordingly ⇒ page 83.
Battery voltage too high or too low
If the symbol lights up, take the vehicle to a specialised workshop and
have the following items checked:
● Poly V-belt
● Battery condition
It is also advisable to check whether the alternator warning lamp has come
on ⇒ page 70.

Electronic Stability Control (ESC)
General Observations
The Electronic Stability Control increases the vehicle's stabil-
ity on the road.
Fig. 153 Centre console
with ESC switch
The ESC is designed to increase the degree of control in situations where
the vehicle approaches the limits of adhesion, especially when accelerating
and cornering. It reduces the risk of skidding and improves stability in all
road conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (ASR) are all integrated into the Electronic Stabil-
ity Control.
How it works
The ESC control unit processes data from the three integrated systems. It al-
so processes additional inputs provided by other high-precision sensors.
These register the vehicle's rotation about the vertical axis (yaw rate), later-
al acceleration, brake pressure and steering wheel angle.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESC
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle
over swerves (tendency of the rear to leave the
road), the brakes will act on the front wheel facing the outside of the bend.
If the vehicle under swerves (tendency to leave the bend), the braking force
is applied to the rear wheel facing the inside of the bend.
The ESC works in conjunction with the ABS ⇒ page 189. If a malfunction
should occur in the ABS, the ESC will also stop working.
Deactivating
The ESC is activated automatically when the engine is started and performs
a self-test routine.
The ESC cannot be deactivated.
190Intelligent technology
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.
Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning. General notes
The electronic differential lock (EDL) helps the vehicle to start moving, ac-
celerate and climb a gradient in slippery conditions where this may other-
wise be difficult or even impossible.
How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels ⇒ page 189. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the
drive wheels is on ice), keep pressing the accelerator gradually until the ve-
hicle starts moving. Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. In this case, the vehi-
cle will continue to run and will have the same running properties as those
of another without EDL.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a uniformly slippery surface (for instance all
four wheels on ice or snow), press the accelerator gradually and careful-
ly. Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.
● Even with EDL, you should always adjust your speed to suit the road
and traffic conditions. Do not let the extra safety features tempt you into
taking any risks when driving. Failure to do so could result in an accident.
Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Take the vehicle to a specialised workshop as soon as possible.
Traction control system (ASR)
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating. General notes
The traction control system (ASR) is one of the functions incorporated in the
Electronic Stability Control (ESC)
