Rims and tires
!Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to provide best
possible performance in conjunction with the
driving safety systems on your vehicle such as
ABS or ESP
®. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding the
following on the tire’s sidewall:
MO = Mercedes-Benz Original equipment
tires
AMG vehicles:
Does not apply to all approved tires on AMG
vehicles. For information on tested and
approved tires for AMG vehicles, contact an
authorized Mercedes-Benz Center.
Using tires other than those approved by
Mercedes-Benz may result in damage that is
not covered by the Mercedes-Benz Limited
Warranty.
!Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz Light
Truck Center. A placard with the recommended
tire inflation pressures is located on the driver’s
door B-pillar (
page 376). Some vehicles may
have supplemental tire inflation pressure infor-
mation for driving at high speeds (
page 381)
or for vehicle loads less than the maximum
loaded vehicle condition (
page 382). If such
information is provided, it can be found on the
placard located on the inside of the fuel filler
flap.The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Light Truck Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire
configuration on your vehicle (Appearance
Package, Sport Package etc.), equipping your
vehicle with winter tires approved for your
vehicle model may also require the purchase of
two or four wheel rims of the recommended size
for use with these winter tires. See an authorized
Mercedes-Benz Light Truck Center for more
information.

Capacities
Vehicle components and their respective
lubricants must match. Therefore use only
products tested and approved by
Mercedes Benz.
Please refer to the Factory Approved
Service Products pamphlet, or inquire at
your Mercedes-Benz Light Truck Center.
Warning!G
Comply with all valid regulations with re-
spect to handling, storing and disposing of

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 PLUS
(Canada vehicles). For a listing of approved
engine oils and oil filters, refer to the Fac-
tory Approved Service Products pamphlet,
or contact an authorized Mercedes-Benz
Light Truck Center.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.
!Using engine oils and oil filters of
specification other than those expressly re-
quired for the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada vehicles),
or changing of oil and oil filter at change intervals
longer than those called for by the Maintenance
System (U.S. vehicles) or FSS PLUS (Canada
vehicles) will result in engine or emission control
system damage not covered by the
Mercedes-Benz Limited Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS PLUS (Canada vehicles)
recommendations for scheduled oil changes.
Failure to do so could result in engine or
emission control system damage not covered by
the Mercedes-Benz Limited Warranty.

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
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 per-
formance, premium unleaded gasoline must be
used. If premium unleaded is not available and
low octane fuel is used, follow these precau-
tions:
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 acceler-
ation.
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 exceed2/3of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.

If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Light
Truck Center.

Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines ne-
cessitates that anticorrosion/antifreeze
coolant used in such engines be
specifically formulated to protect the aluminum parts. (Failure to use such anti-
corrosion/antifreeze coolant will result in
a significantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 anticorrosion/anti-
freeze agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Light Truck Center for service.
