G
WARNING
Certain componentsint he engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is arisk of injur ywhen accessin gthe
engin ecompartment.
As far as possible, allow the engine to cool
down and only touch the componentsd escri-
bed in the following. G
WARNING
When the bonnet is open, and the windscreen wipers are set in motion ,you can be injured by
the wiper linkage. There is arisk of injury.
Always switch off the windscreen wipers and
the ignition before opening the bonnet.
! Make sure that the windscreen wipers are
not folded away from the windscreen. Oth-
erwise, you could damage the windscreen
wipers or the bonnet. X
Make sure that the windscreen wipers are
switched off.
X Pull release lever :on the bonnet.
The bonnet is released. X
Reach intot he gap, pull bonnet catc hhan-

If you lift the bonnet by approximately
40 cm, the bonnet is opened and held open automatically by the gas-filled strut.
Closing the bonnet X
Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
If the bonnet can be raised slightly, it is not
properly engaged. Open it again and close
it with alittle more force. Radiator
Vehicles with adiesel engine: do not cover
the radiator. Do not use thermal mats, insect
protection cover soranythin gsimilar. Doing
so can cause the Onboard Diagnostics Sys-
tem to display inaccurate values. Some of
these values are legally required and must
alway sbec orrect. Engine oil

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).

Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduousc onditions
or increased loads, for example:
R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R for frequent operation in mountainous ter-
rain or on poor road surfaces
R if the engine is often left idling for long peri-
ods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tyres
must be checked more frequently if the vehi-
cle is operated under increased loads. Fur-
ther information can be obtained at aquali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre.
Driving abroad
An extensive Mercedes-Benz Service network is also available in other countries. You can
obtain further information from any
Mercedes-Benz Service Centre. AdBlue

To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the

up as part of the service. Under normal oper-
ating conditions, afull tank of AdBlue ®
should
last until the next service due date.
Depending on how and where the vehicle is
used, there may be an increase in the

qualified specialist workshop only. The
vehicle may otherwise be damaged or
soiled.
Before driving your vehicle outside Europe,
have the AdBlue ®
supply checked at aquali-
fied specialist workshop. If necessary, have
AdBlue ®
topped up. Before aprolonged stay
outside of Europe, consult aqualified special-
ist workshop.
Observe the notes on AdBlue ®

Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man- ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. aring or ice

385Maintenance and care Z

Observe the service intervals in the Service
Booklet or contact aqualified specialist
workshop for more information.
! You should have all work involving the
battery carried out at aqualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery yourself, make sure that:
R you switch off the engine and remove the
key. On vehicles with KEYLESS-GO,
ensure that the ignition is switched off.
Check that all the indicator lamps in the
instrument cluster are off. Otherwise,
electronic components, such as the
alternator, may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R in vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be fitted securely dur- ing operation.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Fire, naked flames and smoking
are prohibited when handling the
battery. Avoid creating sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear suitablep rotective clothing,
in particularg loves, an apron and a
face mask.
Immediately rinse acid splashes
off with clean water. Consult adoc-
tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
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.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz.T hese batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damagedint he event of
an accident.
In order for the battery to achieve the maxi-
mum possibles ervice life, it must always be
sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at aqualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, pleasec ontactaquali-
fied specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Consult aqualified specialist
workshop if you wish to leave your vehicle
parked up for along period of time.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little energy, thus conserving battery power. Battery (vehicle)
