Engine Oils

Engine oils are specifically tested
for their suitability in our engines.
Therefore, use only engine oils
recommended by Mercedes-Benz.
Information on recommended
brands is available at your
authorized Mercedes-Benz dealer.
Please follow maintenance booklet
recommendations for scheduled
oil changes. Failure to do so could
result in engine damage not
covered by the Mercedes-Benz
Limited Warranty.
Engine Oil A dditives
Do not blend oil additives with
engine oil. They may be harmful to
the engine operation.
Damage or malfunctions resulting
from blending oil additives are not
covered by the Mercedes-Benz
Limited Warranty.

A ir C onditioner R efrigerant
Ozone-friendly HFC-134a refrige­
rant and special lubricating oil is
used in the air conditioner system.
Never use R-12 (CFC) or mineral-
based lubricating oil, otherwise
damage to the system will occur.

Brake Fluid

During vehicle operation, the
boiling point of the brake fluid is
continuously reduced through the
absorption of moisture from the
atmosphere. Under extremely hard
operating conditions, this moisture
content can lead to the formation
of bubbles in the system thus re­
ducing the system's efficiency.
The brake fluid must therefore be
replaced every two years, prefer­
ably in the spring.
It is recommended to use only
brake fluid approved by Mercedes-
Benz. Your authorized Mercedes-
Benz dealer will provide you with
additional information.
Prem ium Unleaded G asoline
Caution!
To maintain the engine's dura­
bility and performance, premium
unleaded gasoline must be used.
If premium unleaded is not avail­
able and low octane fuel is used,
follow these precautions:
• have the fuel tank filled only
partially with unleaded regular
and fill up with premium un­
leaded as soon as possible,
• avoid full throttle driving and
abrupt acceleration,
• do not exceed an engine speed
of 3000 rpm, if the vehicle is
loaded with a light load such as
two persons and no luggage,
• do not exceed 2/3 of maximum
accelerator pedal position, if the
vehicle is fully loaded or operat­
ing in mountainous terrain.
