Lubricant additives
!
Do not mix any lubricant additives with
the engine oil. This could damage the
engine. Damage resulting from the use of
such lubricant additives in the engine oil is
not covered by the Mercedes-Benz Limited
Warranty.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select the SAE classification (viscosity) of the
engine oil according to the outside
temperature. The following table shows you
the viscosity classes to be used depending on
the average air temperature.
Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a refrigerant and a special PAG
lubricant.
!
Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system.
Brake fluid
G
Warning!
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake
fluids can be obtained from any authorized
Mercedes-Benz Center.
Coolant
Important safety notes
The coolant is a mixture of water and
anticorrosion/antifreeze. It performs the
following tasks:
R
anti-corrosion protection
R
antifreeze protection
R
raising the boiling point
The cooling system is filled with coolant at the
factory which contains antifreeze/corrosion
inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).
!
Only use premixed coolant solutions.
