Rims and tires
Rims and tires
Only use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as
poor handling characteristics
increased noise
increased fuel consumption
Rims and tires
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and
different tire deformation characteris-
tics that could cause them to come into
contact with the vehicle body or axle
parts. This may result in damage to the
tires or the vehicle.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Light Truck Center. A
tire inflation pressure table is located
on the fuel filler cap of the vehicle. The
tire pressure should be checked regu-
larly and should only be adjusted on
cold tires. Follow tire manufacturer’s
maintenance recommendation includ-
ed with vehicle.

Premium unleaded gasoline
Fuel requirements
Only use premium unleaded fuel.
The octane number (posted at the
p um p) m us t be 91 mi n. It i s an a vera ge
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M) / 2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Gasoline additives
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon depos-
its.
After an extended period of using fuels
without such additives carbon deposits
can build up, especially on the intake
valves and in the combustion area, leading
to engine performance problems such as:
Warm-up hesitation
Unstable idle
Knocking / pinging
Misfire
Power loss
!To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
is not available and low octane fuel is
used, follow these precautions:
Have the fuel tank only partially
filled 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
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.
