compressor to I.
The tire inflation compressor is switched
on. The tire is inflated.
i First, tire sealant is pumped into the tire.
The pressure can briefly rise to approx-
imately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
Allow the tire inflation compressor to run
X
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes:
( page 386).
Y
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes:
( page 386).

If tire sealant leaks out, allow it to dry. It
can then be removed like a layer of film.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene
at a dry cleaner as soon as possible.
Tire pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes:
Switch off the tire inflation compressor.
X
Unscrew the filler hose from the valve of
X
the faulty tire.
Very slowly drive forwards or reverse
X
approximately 30 ft (10 m).
Pump up the tire again.

After a maximum of five minutes the tire
pressure must be at least 180 kPa (1.8 bar/
26 psi).
G WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
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.
Tire pressure reached
G WARNING
A tire temporarily sealed with tire 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 tire that
has been repaired using tire sealant.
! Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
H Environmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes:
Switch off the tire inflation compressor.
X
Unscrew the filler hose from the valve of
X
the faulty tire.
Stow the tire sealant bottle and the tire
X
inflation compressor.
Pull away immediately.
X
The maximum speed for a tire sealed with
tire sealant is 50 mph (80 km/h). The upper
part of the TIREFIT sticker must be affixed
to the instrument cluster in the driver's
field of vision.
Stop after driving for approximately ten
X
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
