Engine oils are specifically tested
for their suitability in our engines.
Therefore, use only engine oils recom­
mended by us. Information on recom­
mended brands is available at your
authorized MERCEDES-BENZ dealer.
Engine Oils
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 reducing the system’s efficiency.
The brake fluid must therefore be re­
placed annually, preferably 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.
Brake Fluid
Premium Unleaded Gasoline
Caution!
To maintain the engines durability and
performance, premium unleaded
gasoline must be used. If premium un­
leaded is not available and low octane
fuel is used, follow these precautions:
• have the fuel tank filled only par­
tially with unleaded regular and fill
up with premium unleaded 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 per­
sons and no luggage,
• do not exceed
2h
of maximum
accelerator pedal position, if the
vehicle is fully loaded or operating
in mountainous terrain.
