at yre press ureof1 80 kPa (1.8 bar/
26 psi) ha snot been attaine dafter five
minutes :(Ypage 381).
i If the tyr esealant leaks out, allow it to dry.
It can then be removed like alayer of film.
If you get tyre sealant on you rclothing,
have it cleaned as soon as possible with
perchloroethylene.
Tyre pressur enot reached If
ap ressure of 180 kPa (1.8 ba r/26 ps i)has
not been achieved after five minutes:
X Switc hoff th etyre inflation compressor.
X Unscrew the filler hos efrom the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximatel y10m.
X Pum pupt he tyreagain.
Af teram aximum 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 atyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.

lnote
Have the used tyre sealant bottle disposed of
professionally, e.g. at aqualified specialist
workshop.
If at yrep ressure of 18 0kPa (1. 8bar/2 6psi)
has been attained after five minutes:
X Switc hoff th etyre inflation compressor.
X Unscrew the filler hos efrom th evalve of
the faulty tyre.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately.
The maximum spee dfor atyre sealed with
tyre sealant is 80 km/h. The upper part of
the TIREFI Tsticker must be affixed to the
instrument cluster in the driver's field of
vision.
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 ashort period, the tyr eistoo
badly damaged. The tyr esealant can not
re pair the tyr einthis instance. Damaged tyres
and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi) (see the fuel filler
flap for values).
X To increase the tyre pressure: switch on
the tyre inflation compressor. Flat tyre
