wheel cleaners may also damage the wheel
paint if the vehicle is not driven after
cleaning.
Therefore, the vehicle’s brake system
should always be warmed-up before it is
parked after cleaning. Drive your vehicle for
several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved
Tire Care and Mercedes-Benz approved
Wheel Care products, take care not to
spray them on the brake disks.
Plastic and rubber partsXUse a gentle dishwashing detergent or mild
detergent for delicate fabrics as a washing
solution.XWipe with a cloth moistened in a lukewarm
solution.
The surface may temporarily change color.
If this is the case, wait for it to dry.GWarning!
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
XUse 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.XUse a standard microfiber cloth and apply
with light pressure.
Steering wheel
XWipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved
Leather Care.
Carpets
XUse Mercedes-Benz approved Carpet and
Fabric Care for cleaning the carpets.
Headliner and shelf below rear window
XUse a soft bristle brush or a dry-shampoo
cleaner in case of excessive dirt.
Seat belts
XOnly 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.
GWarning!
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.
