Caution
Take special care if you have to repair a tyre on a gradient.
Note
Do not use the compressor for longer than 6 minutes at a time,
as it could overheat. When the compressor has cooled down, you
can use it again.
If tyre sealant should leak out, leave it to dry and then pull it off
like foil.
After carrying out a tyre repair remember to buy a new tyre
sealant can at a qualified workshop. This will ensure that the Tyre
Mobility System is operative again.
Please observe the relevant regulations.

lever to position P (automatic gearbox).
