X
Press on/off switch B on 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
approximately 600 kPa (6.0 bar/86 psi).
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. The tyre should then
have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a tyre pressure of 180 kPa (1.8 bar/26 psi) is
achieved after a maximum of 15 minutes, see
"Tyre pressure reached" (
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has not been achieved after a maximum of
15 minutes, see "Tyre pressure not reached"
Y
( page 186).
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 tyre pressure of 180 kPa (1.8 bar/26 psi)
has been reached after 10 minutes:
X
Switch off the tyre inflation compressor.
X
Unscrew the filler hose from the valve of
the defective tyre.
X
Very slowly drive forwards or reverse
approximately 10 m.
X
Inflate the tyre again.
After a maximum of 10 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 characteristics. There is a
risk of accident.

Do not continue driving. Contact a quali-
fied 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 permissible speed for a tyre
sealed with tyre sealant is 80 km/h. The
80 km/h maximum speed sticker must be
affixed to the instrument cluster within the
driver's field of vision.
!
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.
H
Environmental note
Have the used tyre sealant bottle disposed
of professionally, e.g. at a qualified spe-
cialist workshop.
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has been reached after 10 minutes:
X
Switch off the tyre inflation compressor.
X
Unscrew the filler hose from the valve of
the defective 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 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).

WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is
