MERCEDES-BENZ CL CLASS 2010 Owners Manual

Plastic and rubber parts
X
Use a gentle dishwashing detergent or mild
detergent for
delicate fabrics as a washing
solution.
X Wipe with a cloth moistened in a lukewarm
solution.
The surface

may temporarily change color.
If this is the case, wait for it to dry. G
Warning!
Do not use cleaners or cockpit care sprays
containing solvents

to clean the cockpit or the
steering wheel. Cleaners containing solvents
will make the surface porous and vehicle
occupants could suffer serious injuries from
plastic parts coming loose in the event of air
bag deployment.
! Do not use oil, wax or scouring agents.
Otherwise you may scratch or damage the
surface.
Hard plastic trim items
X Use Mercedes-Benz approved Interior Care
on a

soft, lint-free cloth and apply with light
pressure.
COMAND display !
You must
switch off the COMAND display
and allow it to cool prior to cleaning.
! Do not use any liquids or cleaning agents.
These can damage or even destroy the
COMAND display screen.
X Use a standard microfiber cloth and apply
with light pressure.
Steering wheel X
Wipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved

Headliner and shelf below rear window X
Use a soft bristle brush or a dry-shampoo
cleaner in case of excessive dirt.
Seat belts X
Only use clear, lukewarm water and soap.
! The seat belts must not be treated with
chemical cleaning agents. Do not dry the
seat belts at temperatures above 176‡
(80†) or in direct sunlight. G
Warning!
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.
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. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to a
natural aging process. Leather upholstery
may also react to certain ambient influences
such as

high humidity or high temperature by
showing wrinkles for example. Vehicle care

wood trims in your vehicle.

wheel cleaner nor polishes or waxes as
these may be abrasive.
Chrome-plated exhaust tip Regular cleaning and care of chrome-plated
exhaust tips will help to maintain their shine
and the classy appearance.
X
Use Mercedes-Benz approved Chrome
Polishing Paste each time the vehicle has
been washed,

especially during the winter.
! Do not use alkaline cleaners such as
wheel cleaners as they could cause
corrosion. 410
