223

Operation

Engine compartment

1 Cap
2 COLD LEVEL mark

The coolant level should reach the COLD 
LEVEL mark 2 in the reservoir.

Using a rag, turn the cap slowly approx-
imately one half turn to the left to re-
lease any excess pressure.

Continue turning the cap to the left and 
remove it.

Add coolant as required.

Replace and tighten cap.

More information on coolant can be found 
in the “Technical data” section 
(

page 304).

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.

B

Battery acid is caustic. Do not 
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.

224

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.

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

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.

225

Operation

Engine compartment

More information can be found in the 
“Technical data” section (

page 307).

Warning!

G

Washer solvent/antifreeze is highly flam-
mable. Do not spill washer 
solvent/antifreeze on hot engine parts, be-
cause it may ignite and burn. You could be 
seriously burned.

226

Operation

Tires and wheels

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

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

Tires must be of the correct size for the 
rim.

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

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

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

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).

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:

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

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.
