Fully deflating the tyre may take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
X Place the valve extractor back into the vehi-
cle tool kit.
X Stow the collapsible emergency spare
wheel in the emergency spare wheel well
under the luggage compartment and fasten
in place. Flat tyre
Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
X Stop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Firmly depress the parking brake.
X Bring the front wheels into the straight-
ahead position.
X Vehicles with manual transmission:
engage first or reverse gear.
X Vehicles with automatic transmission:
move the DIRECT SELECT lever to P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO: open the
driver's door.
The on-board electronics have status 0,
which is the same as the key having been
removed.
X Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(Y page 147). X
All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door.
X Place the warning triangle (Y page 326) a
suitable distance away. Observe legal
requirements. TIREFIT kit
Using the TIREFIT kit TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up
to 4 mm, particularly those in the tyre tread.
You can use TIREFIT at outside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
There is a risk of accident.
Do not drive any further. Contact a qualified
specialist workshop.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove the tyre sealant bottle, the accom-
panying "max. 80 km/h" sticker and the
tyre inflation compressor from the stowage Flat tyre

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
