Do not switch off the tyre inflation com-
pressor during this phase.
X
Let the tyre inflation compressor run for a
maximum of 15 minutes, then allow it to
cool down.
The tyre pressure must be at least 180 kPa
(1.8 bar/26 psi) in pressure gauge C.
Allow any leaking tyre sealant to dry. It can
then be removed like a layer of film.
Have any clothing stained with tyre sealant
cleaned as soon as possible with perchloro-
ethylene.
Further procedure if the pressure of the
sealed tyre is below 180 kPa

WARNING
If the specified tyre pressure still cannot
be reached, the tyre is too badly damaged.
The tyre sealant cannot repair the tyre in
this instance. Damaged tyres and low tyre
pressures can significantly impair the
vehicle's braking and driving character-
istics. There is a risk of an accident.
Do not drive any further. Contact a quali-
fied specialist workshop.
X
Switch off the tyre inflation compressor.
X
Unscrew the filler hose from the valve of
the defective tyre.
Please note that tyre sealant may escape
when unscrewing.
X
Slow move the vehicle approximately 10 m
forwards or backwards.
X
Pump up the tyre again.
After a maximum of 15 minutes, the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi).
Further procedure if the pressure of the
sealed tyre is at least 180 kPa
X
Switch off the tyre inflation compressor.
X
Unscrew the hose from the valve of the
defective tyre.
Please note that tyre sealant may escape
when unscrewing.
Sealing tyres using the TIREFIT kit
X
Stow the tyre sealant bottle and the tyre
inflation compressor.
X
Perform a test drive.
The maximum permissible speed for a tyre
sealed with tyre sealant is 80 km/h.
X
Stop after driving for approximately 3 km
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). The precise values
are located on the door pillar (B-pillar) on
the driver's side.
X
If necessary, adjust the tyre pressure.
X
Unscrew the filler hose from the valve on
the sealed tyre.
Please note that tyre sealant may escape
when unscrewing.
X
Screw the valve cap onto the valve of the
sealed tyre.
X
Pull the tyre sealant bottle out of the tyre
inflation compressor. The filler hose stays
on the tyre sealant bottle.
X
Drive to the nearest qualified specialist
workshop and have the tyre changed there.
X
Have the tyre sealant bottle and filler hose
replaced as soon as possible at a qualified
specialist workshop.
