Battery

The battery is located in the engine com-
partment.

The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life. Refer to Service Booklet for bat-
tery maintenance intervals.

If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more frequent-
ly.

When replacing batteries, always use bat-
teries approved by Mercedes-Benz.

If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.

i

If the engine is already at its regular op-
erating temperature, the coolant may
be approximately 0.6 in (1.5 cm) above
the COLD LEVEL mark.

G

Observe all safety instructions
and precautions when handling
automotive batteries.

A

Risk of explosion

D

Keep flames or sparks away
from battery. Do not smoke.

allow it to come into contact
with skin, eyes or clothing.

In case it does, immediately
flush affected area with clear
water and seek medical help if
necessary.

Operation

Engine compartment

Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.

Windshield washer system and
headlamp cleaning system*

The windshield washer reservoir is located
in the engine compartment.

1 Cap

Fluid for the windshield washer system and
the headlamp cleaning system* is supplied
from the windshield washer reservoir. It
has a capacity of 8.0 US qt (7.6 l).

During all seasons, add MB Windshield
Washer Concentrate “S” to water. Premix
the windshield washer fluid in a suitable
container.

왘

Use the tab to pull cap 1 upwards
(arrow).

왘

Refill the reservoir with MB Windshield
Washer Concentrate “S” and water (or
commercially available premixed wind-
shield washer solvent/antifreeze, de-
pending on ambient temperatures).

Always use washer solvent/antifreeze
where temperatures may fall below
freezing point. Failure to do so could re-
sult in damage to the washer
system/reservoir.

E

Wear eye protection.

C

Keep children away.

F

Follow the instructions in this
Operator's Manual.

!

Only use washer fluid which is suitable
for plastic lenses. Improper washer
fluid can damage the plastic lenses of
the headlamps.

Operation

Tires and wheels

왔

Tires and wheels

See your authorized Mercedes-Benz Light
Truck Center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and pur-
chase.

Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on
retreads. Mercedes-Benz can therefore
not assure the operating safety of the vehi-
cle when such tires are used.

See your authorized Mercedes-Benz Light
Truck Center for information on tested and
recommended rims and tires for summer
and winter operation.

Important guidelines

앫

Use only sets of tires and rims of the
same type and make.

앫

Tires must be of the correct size for the
rim.

앫

Break in new tires for approximately
60 miles (100 km) at moderate
speeds.

앫

Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire pressure loss or damage to
the tire beads.

앫

If vehicle is heavily loaded, check tire
pressure and correct as required.

앫

Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under

1

/

8

in (3 mm).

앫

When replacing individual tires, you
should mount new tires on the front
wheels first.

Warning!

G

Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See your authorized
Mercedes-Benz Light Truck Center for fur-
ther information. If incorrectly sized rims
and tires are mounted:

앫

The wheel brakes or suspension compo-
nents can be damaged.

앫

The correct operating clearance of the
wheels and the tires are no longer guar-
anteed.

Warning!

G

Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.

When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can re-
sult in the bolts loosening and possibly an
accident.
