0071WARNING Risk of injury and poisoning
from tire sealant
The tire sealant is harmful and causes ir rita ‐
tion. Do not allow it tocome into contact
wi th th e skin, eyes or clo thing, and do not
swallow it. Do not inhale tire sealant fumes.
Ke ep the tire sealant away from children.
If yo u come into contact withth e tire sealant,
obser vethefo llowing:
00BBRinse off the tire sealant from your skin
immediately using water.
00BBIf tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r.
00BBIf tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately.
00BBChange out of any clo thes conta mina‐

The tire inflation compressor is switched on.
The tire is inflated. Fir st, tire sealant is pum‐

Do not switch off the tire inflation compres‐
sor du ring this phase.
00BBLet the tire inflation compressor runfo r a
maximum of ten minu tes.
The tire should then ha veattained a tire
pressure of at least 200 kPa (2.0 bar/
29 psi).
If tire sealant leaks out, make sure you clean the
af fected areas as quickly as possible. It is pref‐
erable touse clean water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene. If, af

200 kPa (2.0 bar/29 psi) has not been ach‐
ie ve d:

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

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‐
