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.
