Cleaning and care of vehicle
Regular and proper care will help to main-
tain the value of your vehicle. The best way
to protect your vehicle from harmful envi-
ronmental influences is to wash it and use
protective treatments regularly.While in operation, even while parked, your
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can
attack the paintwork as well as the vehicle
underbody and cause lasting damage.
Such damage is caused not only by
extreme and varying climatic conditions,
but also by:


Air pollution


Road salt


Tar


Gravel and stone chippingTo avoid paint damage, you should imme-
diately remove:


Grease and oil


Fuel


Coolant


Brake fluid


Bird droppings


Insects


Tree resins, etc.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of
the above adverse influences.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.

598 OperationVehicle careAutomatic car wash
You can have your car washed in an auto-
matic car wash from the start.
To protect the filter system, switch the
automatic climate control to air recir-
culation mode (
page 496).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.When taking the vehicle through an auto-
matic conveyor type car wash, observe the
following instructions.
Vehicles with SmartKey:

electronic parking brake (
page 413).

Switch off the ignition and leave the
SmartKey in the starter switch.Vehicles with KEYLESS-GO*:

Otherwise the caustic spray will damage the
paint or ornamental moldings.
!
Make sure that the windshield wiper switch
is set to0 (
page 400). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.

clean cloth and detergent solution.

Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.

Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light
alloy wheels.Plastic and rubber parts

Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.

Wipe with a cloth moistened in a luke-
warm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.
!

dry cloth, abrasives, solvents or cleaners con-
taining solvents. Do not touch the inside of the
front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
!
Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!
The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
Warning!
G
Do not use cleaners or cockpit care sprays
containing solvents to clean the cockpit or
the steering wheel. Cleaners containing sol-
vents will make the surface porous and vehi-
cle occupants could suffer serious injuries
from plastic parts coming loose in the event
of air bag deployment.

Possible cause/consequence
Suggested solution
-
The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is run-
ning.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged sufficiently.
When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.
When the voltage is above this value again,
the ABS is operational again.
