Remove the cap from valve 7 on the faulty
#
tyre.
Screw filling hose 8 onto valve 7.
#
Insert connector 4 into a 12 V socket in
#
your vehicle.
Switch on the ignition.
#
Press on and off switch 3 on the tyre infla‐
#
tion compressor.
The tyre inflation compressor is switched on.
The tyre is inflated. First, tyre sealant is pum‐
ped into the tyre. The pressure may briefly
rise to approximately 500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation compres‐
sor during this phase!
Let the tyre inflation compressor run for a
#
maximum of eight minutes.
The tyre should then have attained a tyre
pressure of at least 180 kPa (1.8 bar/26 psi).
If tyre sealant leaks out, make sure you clean the
affected area as quickly as possible. It is prefera‐
ble to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy‐
lene.
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after eight minutes:
Switch off the tyre inflation compressor.
#
Unscrew the filling hose from the valve of the
#
defective tyre.
Please note that tyre sealant may leak out when
unscrewing the filling hose.
Drive forwards or reverse very slowly for
#
approximately 10 m.
Pump up the tyre again.
#
After a maximum of eight minutes the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi).
& WARNING Risk of accident due to the
specified tyre pressure not being ach‐
ieved
If the specified tyre pressure is not achieved
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 braking and
handling characteristics.
Do not drive on.
