Operation

Winter driving

Block heater (Canada only)

The engine is equipped with a block
heater.

The electrical cable may be installed at
your authorized Mercedes-Benz Light
Truck Center.

Snow chains

Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.

Observe the following guidelines when
using snow chains:

앫

Use of snow chains is not permissible
with all wheel/tire combinations.

앫

Snow chains should only be used on all
four wheels. With only two chains avail-
able, they should be mounted on the
rear wheels. Follow the manufacturer’s
mounting instructions.

앫

Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Light Truck
Center will be glad to advise you on this
subject.

앫

Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.

i

When driving with snow chains, you
may wish to deactivate the ESP
(

컄

page 81) before setting the vehicle

in motion. This will improve the
vehicle’s traction.

Maintenance

We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Light Truck Center, in
accordance with the Service Booklet at the
times called for by the FSS (Flexible Ser-
vice System).

Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.

FSS will notify you when your next service
is due.

The interval between services depends
on your driving habits. A gentle driving

Resetting the service indicator

In the event that the service on your vehi-
cle is not carried out by an authorized
Mercedes-Benz Light Truck Center, you
can reset the service indicator yourself.

왘

Switch ignition on and immediately
press knob 1 twice within
one second.

The present status for days or distance
is displayed.

왘

Within ten seconds turn the key in
steering lock to position 0 (

컄

page 33).

왘

Press and hold knob 1 while switch-
ing the ignition on.

The present status for days or distance
is displayed once more.

왘

Continue to hold knob 1.

After approximately ten seconds a sig-
nal sounds, and the display shows
10 000 miles (Canada: 15 000 km) for
approximately ten seconds.

왘

Release knob 1.

i

If the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.

Only reset if the proper service has
been performed. Resetting the system
without performing the proper service
as called for by the FSS will cause the
FSS to incorrectly determine the next
service interval which will result in en-
gine damage not covered by the
Mercedes-Benz Limited Warranty.

If the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service dead-
line, you will need to subtract these
days from the days shown in the ser-
vice indicator.

Do not confuse the service indicator
with the engine oil level indicator

Cleaning and care of the vehicle

While in operation, even while parked, your
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can at-
tack the paintwork as well as the
underbody and cause lasting damage.

Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:

앫

Air pollution

앫

Road salt

앫

Tar

앫

Gravel and stone chipping

To avoid paint damage, you should imme-
diately remove:

앫

Grease and oil

앫

Fuel

앫

Coolant

앫

Brake fluid

앫

Bird droppings

앫

Insects

앫

Tree resins, etc.

Frequent washing reduces and /or elimi-
nates the aggressiveness and potency of
the above adverse influences.

More frequent washings are necessary to
deal with unfavorable conditions:

앫

near the ocean

앫

in industrial areas (smoke, exhaust
emissions)

앫

during winter operation

You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.

In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.

Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others ap-
plied later.

Warning!

G

Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.

Never use fluids or solvents that are not de-
signed for cleaning your vehicle.
