NOTETE Damage caused by wrong cleaners

Do not use solvent-based cleaning

agents such as tar remover or wheel

or waxes. Otherwise you may damage

the nish.

ded for Mercedes-Benz.

Leather care: Use a leather care agent that

has been recommended for Mercedes-Benz.

Do not allow the leather to become too damp.

Do not use a microber cloth.

Leather is a natural product. It has natural

surface properties, such as dierences in

structure, marks caused by growth and injury

or subtle color dierences. These surface

properties are characteristics of leather and

not material faults. What's more, leather is

subject to a natural aging process during

which the surface properties change.

Leather care: Use a leather care agent that

has been recommended for Mercedes-Benz.

Do not allow the leather to become too damp.

Do not use a microber cloth.

Regular cleaning and care of the leather

reduces soiling, wear marks and aging dam-

age and thus signicantly extends its life

span. Clothing that can leave stains, e.g.

jeans, can leave discoloration on the leather.
