vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days of
disconnection will not be included in the count

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 Warran-
ty.

315 Operation
Vehicle care
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical
components and connectors from contact
with water and cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax, should be applied to
the engine compartment after every
engine cleaning. Before applying, all
control linkage bushings and joints should
be lubricated. 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
diffused 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.Automatic car wash
You can have your car washed in an
automatic car wash from the start.
Automatic car washes without brushes are
preferable.
To protect the filter system, switch the
climate control or automatic climate
control to air recirculation mode, see
“Air recirculation” (
page 165) for
climate control or (
page 175) for
automatic climate control.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you nay scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.

391 Practical hints
Fuses
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 Center.
The following aids are available to help you
replace fuses.

Fuse chart
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 392). The fuse chart ex-
plains the fuse allocation and fuse
amperages.

Spare fuses
Spare fuses are located in the vehicle
tool kit in the spare wheel well
(
page 356).

Fuse extractor
The fuse extractor is located in the cov-
er of the auxiliary fuse box in the trunk
(
page 394).The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 392)

on the driver’s side of the engine com-
partment (
page 392)

in the trunk (page 394)
Before replacing fuses:
Apply the parking brake (page 54).
Make sure the gear selector lever* is
set to positionP (
page 153) (manual
transmission: to Neutral (
page 149)).
Turn off all electrical consumers.
Turn off the engine (page 55).
Remove the SmartKey from the starter
switch.
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
authorized Mercedes-Benz 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 Center will be glad to advise
you on this subject.
