Brake fluid
GWARNING
The brake fluid constantly absorbsm oisture
from the air. Thi slowers the 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. Thi swould impai rbraking efficiency.
There is ariskofana ccident.
Yo us houl dhavet he brake fluid renewe dat

!Brake fluid corrodes paint, plastic and rub-
ber .Ifp aint, plastic or rubber hasc ome into
contact with brake fluid ,rins ew ithw ater
immediately.
Whe nhandling, storing and disposing of brake
fluid ,pleas eobserve the relevant regulations
and the important safety notes for service prod-
ucts (

Technical data
for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may causedamage to the cool-
ant system and reduce the engine' sservice
life
.
The coolant is amixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
Rcorrosion protection
Rantifreeze protection
Rraises the boiling point
When the vehicl eisfirst delivered, it is filled with
ac oolant mixture that ensure sadequate anti-
freeze and corrosion protection. Coolant must
remai ninthe engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved antifreeze and corrosion
inhibitor that complies with the Mercedes-Benz Specifications for Service Products.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
Check the antifreeze/corrosio ninhibitor con-
centration in the coolant every six months.
The percentag eofcorrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing downt o
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡[-45 †]) .Otherwise, hea twilln ot be
dissipated as effectively.
If ther ehasbeen coolant loss, do not refill only
with water. If the vehicl ehaslost coolant, add
equa lparts water and antifreeze/corrosion
inhibitor. The water used as part of the coolant
mixture must fulfil lcertain requirements; these
are usuall yfulfille dbyd rinking water. If the
water quality is not sufficient, yo umusttrea tthe
water.

Important safety notes
The climate control system of you rvehicle 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 aq ualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
need to be respected.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
