271 Operation
Vehicle care
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 moist-
ened in lukewarm solution. Do not use 
scouring agents.
Hard plastic trim items
Pour Mercedes-Benz approved Interior 
Care onto soft lint-free cloth and apply 
with light pressure.Headliner and rear window shelf
Clean with soft bristle brush, or use a 
dry-shampoo cleaner in case of excessive 
dirt.
Seat belts
The webbing must not be treated with 
chemical cleaning agents. Only use clear, 
lukewarm water and soap. Do not dry the 
webbing at temperatures above 176°F 
(80°C) or in direct sunlight.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 dis-
colored. By lining the seats with a proper 
intermediate cover, contact-discoloration 
will be prevented.
Leather upholstery
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.
Warning!
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.
