information 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 dead-

Do not confuse the maintenance service indica-
tor with the engine oil level indicatorN.
!If the maintenance service indicator was
inadvertently reset, have an authorized
Mercedes-Benz Light Truck Center correct it.
Only reset if the proper maintenance service has
been performed. Resetting the system without
performing the proper service as called for by
the maintenance service indicator will result in
engine damage and/or other vehicle damage not
covered by the Mercedes-Benz Limited

427 Operation
Vehicle care
Do not apply any of these products or wax
if your vehicle is parked in the sun or if the
hood is still hot.
Use the appropriate MB-Touch-Up
Stick for quick and provisional repairs
of minor paint damage (i.e. chips from
stones, vehicle doors, etc.).
Engine 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
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the vehicle underbody, do
not forget to clean the inner sides of the
wheels.
Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
such as Mercedes-Benz approved 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 clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of water, and
a SmartKey with KEYLESS-GO* is in close
proximity, i.e. within approximately 3 ft (approxi-
mately 1 m), the vehicle could be inadvertently
locked or unlocked.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-sratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.

544 Practical hints
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses. They are included with the
vehicle tool kit (
page 495):

Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.

Spare fuses

Fuse extractor
The electrical fuses are located in different
fuse boxes:

Fuse box in engine compartment
(
page 545)

Fuse box in cargo compartment
(
page 545)

Fuse box in passenger compartment
(
page 546)Before replacing fuses:
Apply parking brake (page 68).
Make sure the automatic transmission
is set toP (
page 194).
The gear position indicator in the multi-
function display should be on
P.
Turn off all electrical consumers.
Turn off the engine (page 41).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an au-
thorized Mercedes-Benz Light Truck Center.
iA blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart. Any
Mercedes-Benz Light Truck Center will be glad to
advise you on this subject.
