Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Light Truck
Center will provide you with additional
information.
Premium unleaded gasoline
(gasoline engine)
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 in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with gasoline and the in-
halation of gasoline vapors are damaging to
your health.
! To maintain the engine’s durability and
performance, premium unleaded gasoline must
be used. If premium unleaded gasoline is not
available and low octane fuel is used, follow
these precautions:
ț Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.
ț Avoid full throttle driving and abrupt acceler-
ation.
ț 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.
ț Do not exceed 2 /
3
of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.
