Tyre repairs T MS (T
yre Mobility System)* The Anti-puncture kit* (Tyre Mobility System)
will r
eliably seal punct

ures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure
about 10 minutes after starting the engine.
You should only use the tyre mobility set if the
vehicle is parked in a safe place, you are fa-
miliar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:

the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery ter-
minals.
