Mobility System
Principle
With the Mobility System, minor tyre damage
can be quickly sealed, to allow you to drive on.
For this purpose, liquid sealant is pumped into
the tyres which encloses the damage from the
inside when it hardens.
General
▷ Please observe the notes on the application
of the Mobility System which are on the com‐
pressor and the sealant container.
▷ Applying the Mobility System can be ineffec‐
tive for tyre damage larger than approximately
4 mm.
▷ Contact a Service Partner of the manufac‐
turer or another qualified Service Partner or a
specialist workshop if you are unable to put
the tyre back in operation.
▷ If possible, foreign matter that has penetrated
the tyre should remain inside the tyre. Only
remove foreign objects if they are visibly pro‐
truding from the tyre.
▷ Remove the speed limit sticker from the seal‐
ant container and attach to the steering
wheel.
▷ Using sealants can damage the TPM wheel
electronics. In this case, have the electronics
replaced at the next opportunity.
▷ The compressor can be used to check the
tyre inflation pressure.
