279 Operation
Maintenance
Resetting the maintenance service indicator
In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Light Truck
Center, you can have the maintenance ser-
vice indicator reset. The automotive main-
tenance facility carrying out the
maintenance service will find the informa-
tion for resetting the maintenance service
indicator in the maintenance-relevant in-
formation for your vehicle. Such informa-
tion is available from either your
authorized Mercedes-Benz Light Truck
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.
iIf the maintenance service indicator
was inadvertently reset, have an autho-
rized Mercedes-Benz Light Truck
Center correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper maintenance service as called
for by the maintenance service indica-
tor will result in engine damage and/or
other vehicle damage not covered by
the Mercedes-Benz Limited Warranty.

282 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as
MB Anticorrosion Wax should be applied to
the engine compartment after every en-
gine cleaning. Before applying, all control
linkage bushings and joints should be lu-
bricated. The poly-V-belt and all pulleys
should be protected from any wax.Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently.
Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in ex-
terior rear view mirrors prior to running the
vehicle through an automatic car wash to
prevent damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome
cleaner.
Headlamps, tail lamps, side marker,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
