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 and shelf below rear window
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Leather upholstery
Using aftermarket seat covers or wearing clothing that
have the tendency to give off coloring (e.g. when wet
etc.) may cause the upholstery to become permanently
discolored. By lining the seats with a proper
intermediate cover, contact-discoloration will be
prevented.Wipe leather upholstery with a damp cloth and dry
thoroughly or clean with Mercedes-Benz approved
Leather Care. Exercise particular care when cleaning
perforated leather as its underside should not become
wet.
Hard plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.
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.
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.

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
standard 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..
