XPull out oil dipstick:.
XWipe oil dipstick:using a lint-free cloth.
XInsert oil dipstick :back into the guide tube
as far as it will go and remove it again.
If the level is between MIN mark =and MAX
mark ;, the oil level is adequate.
XIf the oil level has dropped to or below mini-
mum mark =, open cap ?and add engine oil
(
Ypage 253).
The difference in quantity between marks ;

Adding engine oil
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
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.
GWARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.
!Do not use any additives in the engine oil.
This could damage the engine.
Engine oil filler neck (example)
Observe the information regarding approved
motor oil under "Service products and capaci-
ties" (
Ypage 307).
XOpen the hood (Ypage 251).
XUnscrew and remove cap :.
XAdd engine oil.
XReplace cap:on the filler neck and tighten.
When doing so, make sure that the cap
engages correctly.
XCheck the oil level with the oil dipstick
(Ypage 252).
XClose the hood.
Coolant
GWARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original

Adding coolant
XIfthe coolant drops under marker bar=in
the filler neck, add coolant.
Observe the information on the correct cool-
ant mixture rat ioand the required water qual-
ity under "Service products and capacities"
(
Ypage 309). To prevent damage to the
engine co oling system, use only appr oved
corrosion inh ibitor/antifreeze that co mplies
wit h the Mercedes-Benz Specifications for
Service Products.
XReplac e cap:and tighten ina clock wise

XStart the engine.
XSet the temperature inthe veh icleinterior to
the maximum output on the air-conditioning

XAfter approximate lyfive minutes, switch off
the engine again and allow itto cool down.
XCheck the coolant level again and add coolant
ifnecessary.
XClose the hood.

Service products may be poisonous and haz-
ardous to health. There isa risk of injury.
Comp ly with instructions on the use, storage
and dispo sal of service products on the labels
of the respective original containers. Always
store service products sealed intheir original
containers. Always keep service products out
of the reach of ch ildren.
GWAR NING
Opening the hood when the engine isover-
heated or when there isa fire inthe engine
compartment could expose you to hot gases
or other service products. There isa risk of
injury.
Let an overheated engine cool downbefore
opening the hood. Ifthere isa fire inthe
engine compartment, keep the hood closed
and contact the fire department.
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 downand
touch only the components describe d in the
foll owin g.
Brake fluid is hazardous to health. Also observe the safety notes under "Service products and
capacities" (
Ypage 304).
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. Ifthe boilin g point of the brake
fluid is too low,vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!If the brake fluid level in the brake fluid res-
ervoir has fallen to the MIN mark or below,
check the brake system immediately for
leaks. Also check the thickness of the brake
linings. Visit a qualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake fluid corrodes paint, plastic and rub-
ber. Ifpaint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every two years at a qualified specialist workshop. Observe the
information regarding brake fluid in the "Service
products and capacities" section (
Ypage 309).

Maintenance and care
Z
Check the antifreeze/corrosion inhibitor con-
centration inthe coolant every six months.
The percentage of corrosion inh ibitor/ant i-
freeze additiveinthe engine co oling system
should:
Rbe at least 50 %.This way, the engine co oling
system isprotected against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Other wise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
More information can be obtained at any quali-
fied specialist workshop.

Important safety notes
The climate control system of your vehicle is fil-
led with the refrigerant R‑ 134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged. Maintenance work such as adding refrigerant or
replacing components may only be carried out
by a qualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
must be adhered to.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
