336 OperationVehicle carePaintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”, normally
every three to five months, depending on
climate and washing detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface
shows signs of embedded dirt (i.e. loss of
gloss).
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, vehi-
cle 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
Do not use hot water or wash your vehicle
in direct sunlight. Only use 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.

404 Practical hintsFusesThe electrical fuses in your vehicle serve to
stop the supply of electricity to a device
that is malfunctioning. This helps to
prevent damage to the other vehicle
electronics.
The following aids are available to help you
change fuses:
Fuse chart
Spare fuses
Fuse extractor
The electrical fuses are located in different
fuse boxes:
Main fuse box in passenger compart-
ment (
page 405).
Fuse box in engine compartment
(page 406).
Aids for changing fuses
Fuse chart
The fuse chart is found in the main fuse
box in the passenger compartment
(page 405). The amperages of the fuses
are also given there.
Spare fuses
Spare fuses are found in the vehicle tool kit
in the spare wheel well (
page 369).
Fuse extractor
The fuse extractor is also found in the vehi-
cle tool kit in the spare wheel well
(
page 369).
Warning!
G
Only use fuses approved for Mercedes-Benz
with the specified amperage for the system
in question. Otherwise, a short circuit could
result and cause a fire.
!Only install fuses that have been tested
and approved by Mercedes-Benz and
that have the specified amperage rat-
ing.
Otherwise, electrical parts or systems
could be damaged.
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Center.
