Fuels, coolants, lubricants, etc.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any
authorized Mercedes-Benz Center will
provide you with additional information.Premium unleaded gasoline
Warning!G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere. Under extremely strenuous
operating conditions, this moisture content
can lead to the formation of bubbles in the
system, thus reducing the system’s
efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
Warning!G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to
your health.
!To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded gasoline is not avail-
able and low octane fuel is used, follow these
precautions:

Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.

Avoid full throttle driving and abrupt
acceleration.

Do not exceed an engine speed of 3 000 rpm
if the vehicle is loaded with a light load such
as two persons and no luggage.

Do not exceed 2/3of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.
