advertently reset, have an authorized
Mercedes-Benz Center correct it.

Vehicle care
Cleaning and care of vehicle
Regular and proper care will help to
maintain the value of your vehicle. The
best way to protect your vehicle from
harmful environmental influences is to
wash it and use protective treatments reg-
ularly.While in operation, even while parked, your
vehicle is subject to varying external
influences 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 chipping
To avoid paint damage, you should
immediately remove:

Grease and oil

Fuel

Coolant

Brake fluid

Bird droppings

Insects

Tree resins, etc.Frequent washing reduces and / or
eliminates the aggressiveness and
potency of the above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:

near the ocean

in industrial areas (smoke, exhaust
emissions)

during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a
thorough check is a washing of the
underbody followed by a thorough
inspection. Damaged areas need to be
re-undercoated.
Your vehicle has been treated at the
factory with a wax-base rustproofing in the
body cavities which will last for the lifetime
of the vehicle. Post-production treatment Warning!G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle’s doors or windows when cleaning
the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.

Vehicle care
Wet cleaning:
Brush the top with a soft-bristled
brush.
Wash with clear water or with a mild
detergent and an ample supply of
lukewarm water by wiping with a
soft-bristled brush or sponge from
front to rear.Then rinse thoroughly
with clear water.
Wash the top only when heavily soiled.
If only parts of the top have been washed,
wet the entire top and allow it to air-dry
before lowering it into the storage
compartment.For cleaning soft top or wind screen never
use:

gasoline

thinner

tar and stain removers

glass cleaner

similar organic solvents
They will cause damage which is not
covered by the Mercedes-Benz Limited
Warranty.Ornamental moldings
For regular cleaning and care of
ornamental moldings, use a damp cloth.
iIn general, regular spraying or cleaning with
clear water is sufficient to keep the soft top
clean.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome
cleaner. If in doubt whether an ornamental
molding is chrome-plated, contact an authorized
Mercedes-Benz Center.

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.
!Do not use oil, wax or scouring agents on
these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the surface.
Do not attempt to wipe the surface with a dry
cloth or sponge.

fueling
appears while the engine is
running and at operating temperature, the
engine oil level has dropped to
approximately the minimum level.When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.
Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest ser-
vice station where the engine oil should be
topped to the required level with an

Replacing bulbs
Notes on bulb replacement

Only use 12 volt bulbs of the same type
and with the specified watt rating.

Switch lights off before changing a bulb
to prevent short circuits.

Always use a clean lint-free cloth when
handling bulbs.

Your hands should be dry and free of oil
and grease.

If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.

Additional turn signal lamps in the exte-
rior rear view mirrors

High mounted brake lamp

Bi-Xenon* lamps

Front fog lamps

Front side marker lamps
Warning!G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot

drop the bulb

scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the
vehicle. Only have the LEDs replaced by an
authorized Mercedes-Benz Center.
