WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Make sure that engine oil does not spil lout
over the filler neck. Allow the engine to cool
downa nd thoroughly clea nthe components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the oil,t ake care not to spill
any. If oil enters the soil or waterways, it is
harmfu ltothe environment.
! Only use engine oilsa
nd oil filters that
have been approved for vehicles with aser-
vice system. You can obtai nalistoft he
engine oilsa nd oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damag etothe engine or exhaust system is
caused by the following:
R using engine oilsa nd oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil.T
opping up with
too much engine oil can result in damage to
the engine or to the catalytic converter.
Have excess engine oil siphoned off. Example
X Turn cap :anti-clockwise and remove it.
X Top up the engine oil.
If the oil leve lisatorbelow the MIN mark on
the oil dipstick, top up with 1.0 lofe ngine
oil.
X Replace cap :on the filler neck and turn
clockwise.
Make sure that the cap locks securely into place.
X Check the oil level again with the oil dip-
stick (Y page 381).

Checking the coolant level G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is arisk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. G
WARNING
The engine cooling system is under pressure, particularly if the engine is warm. You could
be scalded by hot coolant spraying out when
opening the cap. There is adanger of injury. 382
Engine compartmentMaintenance and care

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clean water and seek medical attention at once. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Vehicles with
apetrol engine: avoid repeated and lengthy startinga ttempts. Otherwise,
the non-combusted fuel may damage the catalytic converter.
HYBRID vehicles: make sure that you read the "HYBRID" Supplement included in the vehicle
literature. You could otherwise fail to recognise dangers, e.g. due to high voltage. Jump-starting

You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain

i Only for certain countries: you can find
the curren tconsumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These documents are delivered with your vehicle.
The consumption figures were, in each
case, based on the currently applicable ver- sion:
R for vehicles that comply with standards
up to and including the EURO 4standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the EURO 5standard, in accordance with

(Y page 473). AdBlue
®
is aw ater-soluble fluid for the
exhaust gas aftertreatmen tofdiesel engines.
It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank ,small amounts
of ammonia vapour may be released.
Ammonia vapours have apungent odour and
are particularly irritating to the skin ,to
mucous membranes and to the eyes. You may experience aburning sensation in your eyes,
nose and throat. You may also experience
coughing and watery eyes.
Do not inhale any ammonia vapours that may
be released. Only fill the AdBlue ®
tank in well-
ventilated areas.
Low outsid etemperatures AdBlue
®
freezes at atemperature of approx-
imately -11 †. The vehicle is delivered from
the factory equipped with an AdBlue ®
pre-
heating system. Winter operation can thus be guaranteed even at temperatures below
-11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destro ythe BlueTEC exhaust gas after-
treatment system.

Impurities in AdBlue ®
(e.g. due to other
servic eproducts, cleanin gagents or dust)
lead to:
