Brake fluid
GWARNING
The brake fluid constantly absorbsm oisture
from the air. Thisl owersthe boiling point of
the brake fluid .Ifthe boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. Thisw ouldimpai rbraking efficiency.
There is ariskofana ccident.
Yo us houl dhavet he brake fluid renewe dat
the specified intervals.
Whe nhandling brake fluid ,observe the impor-
tant safety notes on service products
(
Ypage 290).
The brake fluid change interval scan be found in
the Maintenance Booklet.
Only us ebrake fluid approved by Mercedes-
Benz in accordance with MB-Freigab eorMB-
Approval3 31.0.

iHave the brake fluid regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Importan tsafety 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 downb efore youadd anti-
freeze.M ake surethat antifreeze is not spilled
next to the filler neck. Thoroughly clea nthe
antifreeze from components before starting
the engine.
!Only ad dcoolant that has beenp remixed
with the desire dantifreeze protection. You
coul dotherwise damag ethe engine.
Furthe rinformatio noncoolants 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.Orc on-
tact aqualifie dspecialist workshop.
!Always use asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products whe nhandling coolant
(
Ypage 290).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection downt o
-35 ‡(-37† ), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).

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.

Windshield washer system
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
year round.
Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is fil-
led with refrigerant R‑ 134a.
The instruction label regarding the refrigerant
type 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.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
carried out at aqualified specialist workshop.
