Fuses
The electrical fuses in your vehicle serve to
stop the supply of electricity to a device
that is malfunctioning. This helps to
prevent damage to the other vehicle
electronics. If a fuse is blown, the compo-
nents and systems secured by this fuse
will stop operating.
The following aids are available to help you
change fuses (

Warning!
G
Only use fuses approved for Mercedes-Benz
with the specified amperage for the system
in question. Never attempt to repair or
bridge a blown fuse. Otherwise, a short cir-
cuit could result and cause a fire.!Only install fuses that have been tested
and approved by Mercedes-Benz and
that have the specified amperage
rating. Otherwise, electrical parts or
systems could be damaged.
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Light Truck Center.
!Keep the fuse boxes free by contamina-
tion and wetness. Otherwise, electrical
parts or systems could be damaged.

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 re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Light Truck Center.
Using engine oils and oil filters of specifica-
tion other than those expressly required
for the Maintenance System
(U.S. vehicles) or FSS (Canada vehicles), or
changing of oil and oil filter at change inter-
vals longer than those called for by the
Maintenance System (U.S. vehicles) or
FSS (Canada vehicles) will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehicles)
recommendations for scheduled oil chang-
es. Failure to do so could result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Light Truck
Center will provide you with additional in-
formation.Warning!
G
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
every two years, preferably in the spring.

496 Technical dataFuels, coolants, lubricants, etc.Premium unleaded gasoline
Fuel requirements
Only use premium unleaded fuel.

The octane number (posted at the
pump) must be 91 min. It is an average
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.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials. Never allow sparks,
flame or smoking materials near gasoline!
!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.
