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 232. 
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 239. Top up the oil at the next opportunity ⇒ page 240.
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 239. 
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 204.
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.

Electronic Stability Control (ESC)
General Observations
The Electronic Stability Control increases the vehicle's stabil-
ity on the road.
Fig. 164 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 197. 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. 

198Intelligent 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 197. 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) 

199
Intelligent technology
The traction control system (ASR) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be dif-
ficult or even impossible.
How it works
The ASR works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors , the ASR monitors the speed of the driven wheels
⇒  page 197. If the wheels start to spin, the engine speed is reduced auto-
matically to match the amount of grip available. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS. If a failure occurs in the ABS,
the ASR will also stop working.
In general, the ASR should be left switched on at all times. It should only be
switched off manually in particular circumstances where a certain amount of
wheel slip may be desirable. Examples:
● when driving with snow chains
● when driving in deep snow or on loose surfaces
● when rocking the vehicle backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as possible.
Note
To ensure that the ASR works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒  page 257.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first 200 km
(250 miles); first they must be “run in”. However, the reduced braking ca-
pacity may be compensated by pressing on the brake pedal a little harder.
Avoid overloading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed ⇒
