of the exhaust system, can become very hot.
Workin ginthe engine compartment poses a
risk of injury.
Only touch the following component sdescri-
bed.

Adding engine oil
GWARNING
Certain components in the engine compart-
ment ,such as the engine, radiator and parts
of the exhaust system, can become very hot.
Workingint he engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING

ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck.L et the engine cool down and
thoroughly clean the engine oil off the com-
ponentsb efore starting the engine.
HEnvironmenta lnote
When adding oil, take care not to spill any. If
oil enter sthe soil or waterways, it is harmful to
the environment.
!Use only engine oils and oil filters that are
approved for vehicles with aservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordanc ewith
Mercedes-Benz Specifications for Service
Products is availableata ny authorized
Mercedes-Benz Center. The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level is
above the "max" mark on the dipstick ,too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick ,add 1.1 US qt (1.0 liter) of
engine oil.
XReplace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely.
XCheck the oil level again with the oil dipstick
(Ypage 234).

Technical data

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for ServiceP roducts
310.1.
iWhen the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-
nancei nterval at aqualified specialist work-
shop.

Important safety notes
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nentsort he exhaust system. There is arisk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
!Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give afalse reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 290).
At temperatures above freezing:
XFill the washer fluid reservoir with amixture of
water and windshield washer fluid, e.g. MB
SummerFit.
XAdd 1part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with amixture of
water and washer fluid, e.g. MB WinterFit.
For the correctm ixing ratio refer to the infor-
mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all

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.O therwise, the climate
control system may be damaged.
Servicew ork, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aqualified specialist workshop. All appli-
cable regulations, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
