Observe the notes on the cigarette lighter
(Y page 316). Observe the notes on sockets
(Y page 316).
X Turn the key to position 1in the ignition lock
(Y page 145).
X Press on and off switch ?on the tyre inflation
compressor to ON.
The tyre inflation compressor is switched on.
The tyre is inflated.
First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately
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 a
maximum of ten minutes. The tyre should
then have attained apressure of at least
200 kPa (2.0 bar/29 psi).
If ap ressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes, see "Tyre pres- sure reached" (Y page 340).
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes, see "Tyre
pressure not reached" (Y page 340).
If tyre sealant leaks out, make sure you clean the
affected area as quickly as possible.Itisp ref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy- lene.
Tyre pressure not reached If
at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Very slowly drive forwards or reverse approx-
imately 10 m.
X Pump up the tyre again.
After amaximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/
29 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged.T he 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.
Tyre pressure reached G
WARNING
At yre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitablef or higher speeds. There is arisk of
accident.
You should therefore adapty our driving style
accordingly and drive carefully.Don ot exceed
the specified maximum speed with atyre that
has been repaired using tyre sealant.
The maximum permissibles peed foratyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the
instrument cluster where it will be easilys een 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. ataqualified specialist
workshop.
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten 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 inflation
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). 340
