Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Brake fluid
GWARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low,v aporpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui dreneweda t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(
Ypag e315).
The brake flui dchange interval scan be found in
the Maintenance Booklet.
Only use brake flui dapproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval3 31.0.
Information about approved brake flui dcan be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake flui dregularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly cleant he
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
coul dotherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aqualified specialist workshop.
!Always use asuitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosiona nd
overheating.
iHave the coolant regularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypag e315).
The coolant is amixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).

The antifreeze concentrate/corrosion inhibitor
concentration 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 ,hea tw ill no tbe

Important safety notes
GWARNING
Windshieldw asher concentrate coul dignite if
it comes into contact with hot engine compo-
nents or the 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 MB SummerFi tand MB WinterFit
washer flui dshould be mixed together. The
sprayn ozzles may otherwise become
blocked.
Do not use distille dorde-ionized water. Other-
wise, the levels ensor may giveafals ereading. When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypag
e315).
At temperatures above freezing:
XFill the washer flui dreservoir with amixture of
water and windshield washer fluid, e.g. MB
SummerFit.
Add 1part MB SummerFi tto100 parts water.
At temperatures below freezing:
XFill the washer flui dreservoir with amixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing 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 flui dall
yea rround.
Climate control system refrigerant
Important safety notes
The climate control system of you rvehicleisf il-
led with refrigerant R ‑134a.
The instruction label regarding the refrigerant
type use dcan be found on the left, on the under-
side of the hood.
!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.
Service work, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aqualified specialist workshop. All appli-
cabl eregulations, as wellasS AE standard J639,
must be adhered to.
Always have work on the climate control system
carrie dout at aqualified specialist workshop.
