Do not use any care or cleaning products
containing solvents to clean the cockpit.&WARNING Risk of injury or fatal injuries
from bleached seat belts
Bleaching or dyeing seat belts can severely weaken them.

416Maintenance and care

\bLeather is a natural product. It exhibits natural
surface properties such as di"Merences in
structure, marks caused by growth and injury or subtle color di"Merences. These surface
properties are characteristics of leather and not material defects. Leather is also subjectto a natural aging process during which the
surface properties change.
Genuine leather seat covers
= Vacuum up dirt such as crumbs or dust and
then clean the seat covers with a damp cotton
cloth and wipe down with a dry cloth. Regu-
larly clean the seat covers.
= For heavy soiling: use a leather care agent rec-
ommended for Mercedes-Benz a"sercare.
= Leather care: use a leather care agent that
has been recommended for Mercedes-Benz.
= Do not use a micro"Nber cloth.
= Do not allow the leather to become too damp.
= Do not use oil-based cleaning and care prod-
ucts.

Waves or wrinkling in the seat cover may
occur due to the stress on the seat; this is
caused by the natural leather material.
Regular cleaning and care of the leather
reduces soiling, wear marks and aging dam-
age and thus signi"Ncantly extends its life
span. Clothing that can leave stains (e.g.
jeans) may discolor the leather.
DINAMICA seat covers
= Vacuum up dirt such as crumbs or dust and
then use a damp cloth to clean.
= Do not use a micro"Nber cloth.
Fabric seat covers
= Vacuum up dirt such as crumbs or dust and
then use a damp micro"Nber cloth and a 1%
soap solution to clean the entire seat cover. Do not spot clean.
= Use cleaning and care products recommen-
ded for Mercedes-Benz.
= Do not use oil-based cleaning and care prod-
ucts.
EASY-PACK trunk box
= Clean with a damp cloth.
= Do not use any alcohol-based thinners, gaso-
line or abrasive cleaning agents.Maintenance and care417
