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

well underneath the luggage compartment
floor (Y page 327). X
Affix part :of the sticker within the driv-
er's field of vision.
X Affix part ;of the sticker near the valve
on the wheel with the defective tyre. G
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

X Press on/off switch =on the tyre inflation
compressor to I.
The tyre inflation compressor is switched
on. The tyre is inflated.
i First, tyre sealant is pumped into the tyre.
The pressure can briefly rise to approx-
imately 500 kPa (5 bar/73 psi). 330
Flat tyreBreakdown assistance

Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for
five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tyre inflation com-
pressor for longer than eight minutes at a
time without a break. It may otherwise
overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
If a pressure of 180 kP a(1 .8 ba r/26 psi) has
been achieved after five minutes, see
(Y page 331).
If a pressure of 180 kPa (1.8 ba r/26 psi) has
not been achieved after five minutes, see
(Y page 331).
Tyre pressure not reached If a pressure of 180 kPa
(1.8 ba r/26 psi) has
not been achieved after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again.
After a maximum of five minutes the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and a tyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop. Tyre pressure reached X
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
! After use, excess tyre sealant may run out
of the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag that contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately. G
WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum speed for a tyre sealed with
tyre sealant is 80 km/h. The "max. 80 km/h"
sticker must be affixed to the instrument clus-
ter within the driver's field of vision.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too
badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres
and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.

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
