The tire inflation compressor is switched on.
The tire is inflated. Fir st, tire sealant is pum‐
ped into the tire. The pressure may brief ly
ri se toappr oximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation compres‐
sor du ring this phase. #
Let the tire inflation compressor runfo r a
maximum of eight minutes.
The tire should then ha veattained a tire
pressure of at least 180 kPa (1.8 bar/26 psi).
If tire sealant lea ksout, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clear water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If a ti repressure of 180 kPa (1.8 bar/26 psi)
has not been attained af ter eight minutes: #
Switch off the tire inflation compressor. #
Unscr ew thefilling hose from theva lve of the
fa ulty tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose. #
Drive forw ards or reve rseve ry slowly for
appr oximately 33 ft(10 m). #
Pump up the tire again.
Af ter a maximum of eight minutes the tire
pressure must be at least 180 kPa (1.8 bar/
26 psi). &
WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te rth e specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this ins tance.
Dama ged tires and a tire pressure that is too
low can significantly impair braking and han‐
dling characteristics. #
Do not continue driving. #
Consult a qualified specialist workshop. 360

A tire temp orarily sealed with tire sealant
impairs driving characteristics and is not
suitable for higher speeds. #
Adapt your driving style according lyand

WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te r a brief drive, the tire is too badly dam‐
aged. The tire sealant cannot repair the tire
in this ins tance.
Dama ged tires and tire pressure that is too
low can significantly impair the braking prop‐

Do not continue driving. #
Consult a qualified specialist workshop. In cases such as
the one mentioned abo ve, con‐
