heater.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:
Use of snow chains is not permissible
with all wheel/tire combinations.
Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.

proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 69) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.

´Major service (B)
Depending on operating conditions
throughout the year, one of the following
service symbols is also shown:
9 1000 Calculated distance remain-
ing, e. g. service in
1000 miles (km)š 10 Calculated remaining time in
days, e. g. service in 10 days
Clearing the service indicator

iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-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:.

194 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected 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 out-
side 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 clean-
er.
Headlamps, side makers, tail lamps,
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.

The yellow “CHECK ENGINE”
malfunction indicator lamp
comes on while driving.
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the

tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the passenger
compartment near the engine hood
release.
The fuel cap is not closed tight.
