Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System (U.S. vehicles, Canada vehicles,
depending on vehicle production date) or
FSS PLUS (Canada vehicles, depending on
vehicle production date). For a listing of
approved engine oils and oil filters, refer to
the Factory Approved Service Products
pamphlet (USA only), or contact an autho-
rized Mercedes-Benz Center.Engine oil additives
Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
!Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System
(U.S. vehicles, Canada vehicles, depending on
vehicle production date) or FSS PLUS (Canada
vehicles, depending on vehicle production date),
or changing of oil and oil filter at change intervals
longer than those called for by the Maintenance
System (U.S. vehicles, Canada vehicles, depend-
ing on vehicle production date) or FSS PLUS
(Canada vehicles, depending on vehicle produc-
tion date) will result in engine or emission control
system damage not covered by the
Mercedes-Benz Limited Warranty.
Please follow Maintenance System
(U.S. vehicles, Canada vehicles, depending on
vehicle production date) or FSS PLUS (Canada
vehicles, depending on vehicle production date)
recommendations for scheduled oil changes.

Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide 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 condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement inter-
val.
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 fuels and the inha-
lation 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 acceler-
ation.

D o n o t e x c e e d a n e n g i n e s p e e d o f 3 0 0 0 r p m
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
operating in mountainous terrain.
