300 Breakdown assistance
Remove the valve cap from valve
#
faulty tire.
Screw filling hose 8 onto valve 7.
#
Insert plug 4 into a 12 V socket in your
#
vehicle.
Switch on the ignition.
#
Switch on the tire inflation compressor using
#
On/Off switch 3.
The tire is inflated. First, tire sealant is pum‐
ped into the tire. The pressure may briefly
rise to approximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation compres‐
sor during this phase!
Let the tire inflation compressor run for a
#
maximum of ten minutes.
The tire should then have attained a tire
pressure of at least 200 kPa (2.0 bar/
29 psi).
If tire sealant leaks out, make sure you clean the
affected area as quickly as possible. It is prefera‐
ble to use clean water.
If you get tire sealant on your clothing, have it
cleaned as soon as possible with perchloroethy‐
7 on the
lene.
If, after ten minutes, a tire pressure of
200 kPa (2.0 bar/29 psi) has not been
attained:
Switch off the tire inflation compressor.
#
Unscrew the filling hose from the valve of the
#
faulty tire.
Please note that tire sealant may leak out when
unscrewing the filling hose.
Drive forwards or in reverse very slowly for
#
approximately 33 ft (10 m).
Pump up the tire again.
#
After a maximum of ten minutes the tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
& WARNING Risk of accident due to the
specified tire pressure not being attained
If the minimum 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.
The braking and driving characteristics may
be greatly impaired.
Do not continue driving.
#
Consult a qualified specialist workshop.
#
If, after ten minutes, a tire pressure of
200 kPa (2.0 bar/29 psi) has been attained:
Switch off the tire inflation compressor.

Unscrew the filling hose from the valve of the
