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.

196Driving and the environment
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
warning lamp for the diesel engine particulate filter will light up. This
does not represent a fault, it is a warning that indicates that the filter has
not been able to regenerate automatically and that you must carry out a
cleaning cycle, as indicated in ⇒ page 81.
WARNING
● The diesel engine particulate filter may reach extremely high temper-
atures; the vehicle should be parked so that the exhaust pipe does not
come into contact with flammable materials underneath the vehicle. Oth-
erwise there is a risk of fire.
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur content may significantly reduce
the useful life of the diesel particulate filter. Your Technical Service will be
able to tell you which countries have diesel with a high sulphur content. Economical and environmentally friendly
driving
Economical and environmentally friendly driving
Fuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an eco-
nomical driving style and anticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%. Some tips on how to help you
reduce pollution while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a
gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 74.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.

Checking and refilling levels
Winter driving
Diesel can thicken in winter.
Winter-grade diesel
When using summer-grade diesel fuel, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, winter-grade diesel fuel is available in some countries during
the cold months. It can be used at temperatures as low as -22 °C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with the Technical Services
or filling stations in the country concerned regarding the type of diesel fuels
available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter-grade diesel that is
safe to -15 °C.
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24 °C, simply place the vehicle in a warm
place for a while.
CAUTION
Do not mix fuel additives (thinners or similar products) with diesel fuel. Bonnet
Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
● Never open the expansion tank when the engine is hot. The cooling
system is under pressure.
