Window cleaning
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
Note:
For safety reasons, switch off wiper and remove key
from steering lock before cleaning the windshield,
otherwise the wiper motor can suddenly turn on and
cause injury.
Light alloy wheels
Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care, using a soft
bristle brush and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could
lead to corrosion.Instrument cluster
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly or clean
with Mercedes-Benz approved Leather Care.
Cup holder
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Note:
For ease of cleaning, the cup holder between the front
seats can be removed by pulling it up when in its closed
position.

The webbing must not be treated with chemical
cleaning agents. Use only clear, lukewarm water and
soap. Do not dry the webbing at temperatures above
176 F (80 C) or in direct sunlight.
Headliner, shelf behind roll bars, and other hard
plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.
Soft top
Clean soft top with soft top raised and locked. Lower the
soft top into the storage compartment only if the top is
completely dry. If the top is kept in the storage
compartment for a lengthy period, raise it and air it out
with the windows down about every 4 months. Dry cleaning:
Brush top (always from front to rear) with a soft-bristled
brush.
Wet cleaning:
Brush the dry top. Wash 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.
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.
Wipe the rear window with a cloth soaked with a mild,
non-abrasive detergent, rinse and rub dry.
Do not use sharp-edged instruments for the removal of
ice and snow.
Notes:
Never run the vehicle through an automatic car wash
with th e sof t top in pla ce or use a power wa sher to cl ean
it, as you may damage the soft top material.
Remove bird droppings immediately. The organic acid
damages the material and causes the soft top to leak.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely
weaken them. In a crash they may not be able to
provide adequate protection.

In general, regular spraying or cleansing with clear
water is sufficient to keep the top clean.
Wash the top only when heavily soiled.
Light colored soft tops should be cleaned frequently to
prevent spots and dirt from setting in, which could stain
and discolor the soft top material permanently.
Caution!
Never use any gasoline, thinner, tar and stain removers,
glass cleaner, or similar organic solvents to clean the
soft top, plastic window or wind screen. They will cause
damage which is not covered by the Mercedes-Benz
Limited Warranty.
Headliner
Soft top:
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.Wind screen
Use only water or mild detergent to clean the wind
screen.
Automatic antenna
For trouble-free operation of the automatic antenna, we
recommend that you clean the antenna mast
periodically.
Wiper blade
Clean the wiper blade rubber with a clean cloth and
detergent solution.
Note:
For safety reasons, remove key from steering lock before
cleaning the wiper blade, otherwise the wiper motor
can suddenly turn on and cause injury.
Headlamp cleaning system
The condition of the wiper blades is important for
satisfactory cleaning of the headlamp lenses. We
therefore recommend that the blades be inspected
regularly.

Caution!
To maintain the engine‘s durability and performance,
premium unleaded gasoline must be used. If premium
unleaded is not available and low octane fuel is used,
follow these precautions:
• have the fuel tank filled only partially with unleaded
regular and fill up with premium unleaded as soon
as possible,
• avoid full throttle driving and abrupt acceleration,
• do not exceed an engine speed of 3000 rpm, if the
vehicle is loaded with a light load such as two
persons and no luggage,
• do not exceed
2/3 of maximum accelerator pedal
position, if the vehicle is fully loaded or operating in
mountainous terrain.Fuel requirements
Use only Premium unleaded meeting ASTM
standa rd D 439:
The octane number (posted at the pump) must be
91 min. It is an average of both the Research (R) octane
number and the Motor (M) octane number: [(R+M)/2].
This is also known as ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates such as
Ethanol, IPA, IBA and TBA can be used provided the
ratio of any one of these oxygenates to gasoline does not
exceed 10%, MTBE not to exceed 15%.
The ratio of Methanol to gasoline must not exceed 3%
plus additional cosolvents.
Using mixtures of Ethanol and Methanol is not allowed.
Gasohol, which contains 10% Ethanol and 90% unleaded
gasoline, can be used.
These blends must also meet all other fuel requirements
such as resistance to spark knock, boiling range, vapor
pressure etc.
