WARNING Risk of accident when using
tyre sealant
In thefo llowing situations, the tyre sealant is
unable toprov ide suf ficient breakdown assis‐
ta nce, as it is unable toseal the tyre prop‐

WARNING Risk of inju ryand poisoning
from tyre sealant
Ty re sealant is hazardous tohealth and cau‐
ses ir rita tion. Do not allow it tocome into
contact wi thyour skin, eyes or clo thing, and do not swallow it. Do not inhale any
vapours.
Ke ep the tyre sealant away from children.
Obser vethefo llowing if you come into con‐
ta ct wi th the tyre sealant: #
Rinse off the tyre sealant from your skin
using water immediatel y. #
If tyre sealant gets into your eyes, thor‐
oughly rinse them using clean water
immediatel y. #
If tyre sealant has been swallowe d,
th oroughly rinse out your mouth imme‐
diately and drink plenty of water.Do not
induce vomiting and seek medical

If th e specified tyre pressure is not achie ved
af te rth e specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the

WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs driving characteristics and is not
suitable for higher speeds. #
Adapt your driving style according lyand
drive carefull y. #
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. #
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h. #
