i First, tyre sealant is pumped into the tyre.
The pressure may briefly rise to approx-
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
five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tyre
pressure reached" (
Y
page 359).
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes, see
"Tyre pressure not reached" (
Y
page 359).
i If the 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.
Tyre pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been attained 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
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 upper part of the
TIREFIT sticker must be affixed to the instru-
ment cluster where it will be easily seen by
the driver.
!
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 which contained the TIREFIT kit.
H Environmental note
Have the used tyre sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes:
X
Switch off the tyre inflation compressor.
X
Unscrew the filler hose from the valve of
the faulty tyre.
X
Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X
Pull away immediately.
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
