Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 272)
i Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a Mercedes-Benz
Service Centre.
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 Apply the electric parkin gbrake manually
(Y page 147).
X Bring the front wheels into the straight-
ahead position.

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 127).
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 whilst 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 260) a
suitable distance away.O bserve 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. Flat tyre

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.

Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor.
The tyre pressure mus tnow 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.
i In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
