Cleaning wooden trim and trim ele-
ments !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
X Wipe the wooden trim and trim elements
with a damp, lint-free cloth, e.g. a microfi-
bre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.
! Observe the following when cleaning:
R clean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth. Make sure that
the leather does not become soaked. It
may otherwise become rough and
cracked. Only use leather care agents
that have been tested and approved by
Mercedes-Benz. You can obtain these
from a qualified specialist workshop.
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid).
R clean cloth covers with a microfibre cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning
results depend on the type of dirt and
how long it has been there.
R clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines. i
Note that regular care is essential to
make sure that the appearance and com-
fort of the covers are retained over time.
Cleaning the seat belts !
Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
at temperatures above 80 † or in direct
sunlight.
X Use clean, lukewarm water and soap solu-
tion.
Cleaning the roof lining and carpets X
Roof lining: if it is very dirty, use a soft
brush or a cleaning agent recommended
and approved by Mercedes-Benz.
X Carpets: use the carpet and textile clean-
ing agents recommended and approved by
Mercedes-Benz. Care
323Maintenance and care Z

wheels and tyres for damage. Hidden tyre
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the tyres and wheels
checked at a qualified specialist workshop.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
can get damaged. Notes on regularly inspecting wheels
and tyres G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
R Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 351). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle. Do not fit any other valve caps or sys-
tems, e.g. tyre pressure monitoring sys-
tems.
R Regularly check the pressure of all the tyres
including the emergency spare wheel or the spare wheel, particularly prior to long trips,
and correct the pressure as necessary
(Y
page 353). Tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached.. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the emergency spare wheel/spare wheel. Operation
