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

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

imately 500 kPa (5 bar, 73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for a
maximum of ten minutes. The tyre should
the nhave attained a pressure of at least
200 kPa (2.0 bar, 29 psi).
! Do not operate the tyre inflation com-
pressor for longer than ten minutes at a
time without a break .Itmay otherwise
overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
If a pressure of 200 kP a(2 .0 ba r,29 psi) has
bee nachieved afte rten minutes, see
(Y page 265).
If a pressure of 200 kPa (2.0 ba r,29 psi) has
not bee nachieved afte rten minutes, see
(Y page 265).
