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

WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not
inhale TIREFIT fumes. Keep tyre sealant away
from children. There is a risk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
i If tyre sealant leaks out, allow it to dry. It
can then be removed like a layer of film.
If you get tyre sealant on your clothing,
have it cleaned as soon as possible with
perchloroethylene. X

Operation with a trailer:
the applicable
value for the rear tyres is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
The table inside the fuel filler flap may state
tyre pressures for different load conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary;
for more information, please refer to the vehi-
cle's registration documents.
The tyre pressures specified on the fuel filler
flap apply to all tyres approved for this vehi-
cle, if not stated otherwise. If a tyre size precedes a tyre pressure, the
following tyre pressure information is only
valid for that tyre size.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and
malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is
a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
speed at which you are driving and the load
on the tyres, the tyre temperature and thus
the tyre pressure change by approximately
10 kPa per 10 † (0.1 ba r/1.5 psi). Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g.
aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. 354
