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:

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

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.

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.

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 
(

page 81) before setting the vehicle 

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

Operation

Maintenance

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.

1 Knob
2 Display in the speedometer

Approximately one month before your next 
service is due, the type of service is indi-
cated in the speedometer display 2:
9

Minor service (A)

½

Major service (B)

The following information, depending on 
operating conditions throughout the year, 
is also shown:

calculated distance remaining

calculated remaining time in days

Clearing the service indicator

The service indicator is automatically 
cleared after ten seconds when you switch 
on the ignition or when reaching the ser-
vice threshold while driving. You can also 
clear it yourself.

Press knob 1.

i

The interval between services depends 
on your driving habits. A gentle driving 
style, moderate engine speeds and the 
avoidance of short-distance trips will 
lengthen the interval between services.

Operation

Maintenance

Service term exceeded

If you have exceeded the suggested ser-
vice term:

the

9 or ½ symbol appears in 

the display 2 for 30 seconds and a 
signal sounds after switching on the 
ignition.

it is preceded by a “–” (minus symbol).

The Mercedes-Benz Light Truck Center will 
reset the service indicator following a com-
pleted service.

Calling up the service indicator

Within one second press knob 1 
twice.

The FSS display will appear for 
ten seconds.

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.

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

The present status for days or distance 
is displayed.

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

page 33).

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

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

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.

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

Operation

Vehicle care

Vehicle care

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:

Air pollution

Road salt

Tar

Gravel and stone chipping

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

Grease and oil

Fuel

Coolant

Brake fluid

Bird droppings

Insects

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:

near the ocean

in industrial areas (smoke, exhaust 
emissions)

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.
