case; observe possible restrictions of the
approved SAE viscosity classes)
To achieve the lowest possible fuel consumption,
it is recommended to use the engine oil speciNca-
tions marked in the table for the lowest SAE vis-
cosity class. Possible restrictions of the approved
SAE viscosity classes must be observed.

WARNING Risk of an accident due t
o
vapour pockets forming in the brake sys-
tem
The brake Ouid cons
tantly absorbs moisture
from the air. This lowers the boiling point of
the brake Ouid. If the boiling point is too low,
vapour pockets may form in the brake system
when the brakes are applied hard. This impairs the braking
eMect. 
Have the brake Ouid r
enewed at the
speciNed intervals. Have the brake
Ouid r
egularly replaced at a quali-
Ned specialist workshop.
Only use a brake Ouid appr
oved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0. Coolant

NOTE Damag
e caused by incorrect cool-
ant 
Only use coolant that has been premixed
wit
h the required antifreeze protection.
Information on coolant is available at the fol-

stem is not suPciently protected against
overheating and corrosion at high outside

Observe the instructions in the
Mer
cedes-Benz SpeciNcations for Oper-
ating Fluids 320.1. Have the coolant regularly replaced at a
q
ualiNed
specialist workshop.
Proportion of antifreeze concentrate in the cool-

ously.
Recommended windscreen washer Ouid:
= above freezing point: e.g. MB SummerFit
= below freezing point: e.g. MB WinterFit
For the correct mixing ratio, refer to the informa-
tion on the antifreeze container.
