specialist workshop.
4 The yellow engine
oil level warning
lamp lights up and
the warning buz-
zer sounds after
starting the
engine or while
the vehicle is in
motion.The engine oil level is above the maximum level.
There is a risk of damaging the engine or catalytic converter.
XCheck the oil level with the oil dipstick (Ypage 222).
XIf the oil level is too high: have the engine oil extracted as soon as
possible at a qualified specialist workshop.
XIf the oil level is correct: have the malfunction rectified as soon as
possible at a qualified specialist workshop.
4 On vehicles with a
diesel engine, the
yellow warning
lamp lights up
repeatedly during
the journey.There is a malfunction in the engine oil level display.
XHave the vehicle checked immediately at a qualified specialist
workshop.
%The yellow cool-
ant level warning
lamp lights up
while the engine
is running.The coolant level is too low.
Never run the engine if the coolant level is too low. The engine could
overheat and be damaged.
XStop the vehicle as soon as possible, paying attention to road and
traffic conditions.
XSwitch off the engine and let it cool down.
XAdd coolant and be sure to observe the warning notes
(Ypage 223).
XIf you need to add coolant frequently, have the engine cooling sys-
tem checked at a qualified specialist workshop.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The fuel injection system operates with a high
voltage. If you touch the live components, you could receive an electric shock. There is a risk
of injury.
Never touch components of the fuel injection
system when the ignition is switched on.
The live components of the fuel injection system
are, for example, the injectors.
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
If you have to carry out work in the engine com-
partment, only touch the following components:
RHood
ROil dipstick
REngine oil filler neck cap
RWasher fluid reservoir cap
RCoolant expansion tank cap
Opening the hood
!Make sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield wip-
ers or the hood.

Diesel
Fuel grade
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
!Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers. This will prevent malfunctions in the fuel sys-
tem due to contaminated fuel.
!You will damage the diesel engine if you do
not refuel with ULSD or a diesel fuel with a
sulfur content of more than 15 ppm.
!Do not use the following:
Rmarine diesel
Rheating oil
Rvegetable oil
Rgasoline
Rparaffin
Rkerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. This can other-
wise lead to engine damage. This does not
include flow improvers. For further informa-
tion, see "Flow improvers".
Usually you will find information about the fuel
grade on the filling pump. If there is no identifi-
cation on the filling pump, consult a gas station
attendant.
For mo
re information about refueling
(Ypage 126).
Diesel at very low outside temperatures
GWARNING
If you heat fuel system components, e.g. with
a hot-air gun or open flame, these compo-
nents could be damaged. This can cause fuel
to escape and ignite. Depending on the type
of damage, fuel may also not escape until the
engine is running. There is a risk of fire and
explosion.
Never heat fuel system components. Contact
a qualified specialist workshop to rectify the
malfunction.
Refill only with commercially available ULTRA-
LOW SULFUR DIESEL (ULSD, maximum sulfur
content 15 ppm), which fulfills the ASTM D975
standard.
The flow properties of diesel may be inadequate
at low outside temperatures due to paraffin sep-
aration.
iMalfunctions resulting from paraffin sepa-
ration can only be rectified by heating the
entire fuel system. Park the vehicle in a
heated garage, for example.
