iFirst, tire sealant is pumped into the tire.
The pressure can briefly rise to
approximately 500 kPa (5 bar/73 psi).
Do notswitch off the tire inflation
compressor during this phase.
XLet the tire inflation compressor run for a
maximum of tenminutes. The tire should
thenhave attained a pressure of at least
200 kPa (2.0 bar/29 psi).
!Do notoperate the tire inflation
compressor for longer than ten minutes at
a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
Ifapressure of 200 kPa(2.0 bar/29 psi) has
been attained after a maximum of after ten
minutes, see (Ypage 298).
Ifapressure of 200 kPa(2.0 bar/29 psi) has
not been attained after a maximum of ten
minutes, see (Ypage 298).
iIf tire sealant leaks out, allow it to dry.It
can then be removed like a layeroffilm.
If your clothes are soiled with tire sealant,
have themcleaned with perchloroethylene
at a dry cleaner as soon as possible.
Tire pressure not reached
Ifapressure of 200 kPa(2.0 bar/29 psi) has
not been achieved after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XVery slowly drive forwards or reverse
approximately 30 ft (10 m).
XPump up the tire again.
After a maximum of ten minutes, the tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
GWARNING
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
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
GWARNING
Atire 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.
!After use, excess tire 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.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. ataqualified specialist
workshop.
Ifatire pressure of 200 kPa(2.0 bar/29 psi)
has beenachieved afterten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XStow the tire sealant bottle and the tire
inflation compressor.
XPull away immediately.
The maximum speed for a tire sealed with tire
sealant is 50 mph(80km/h). The upper part
of the TIREFIT sticker must be affixed to the
instrument cluster in the driver's field of
vision.

XStop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure mustnow be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, 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
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
XCorrect the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) (for the values,
see the Tire and Loading Information
placard on the driver's side B-pillar or tire
pressure table on the fuel filler flap).
XTo increase the tire pressure:switch on
the tire inflation compressor.
XTo reduce the tire pressure:depress
pressure release buttonnext to
pressure gauge.
XTo remove the tire sealant bottle from the
tire inflation compressor, press together
the locking tabs on the yellow cap.
XPull the tire sealant bottle out of the tire
inflation compressor.
The filler hose remains attached to the tire
sealant bottle.
XStow the tire sealant bottle and the tire
inflation compressor.
XDrive to the nearest qualified specialist
workshop and have the tire changed there.
XHave the tire sealant bottle and the filler
hose replaced as soon as possible at a
qualified specialist workshop.
XHave the tire sealant bottle replaced every
four years at a qualified specialist
workshop.
