A tire should only be repaired with
the emergency tire puncture repair
If you have a flat tire
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-

Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair. Driving with a
flat tire may cause a circumferential groove on the side wall. In such a
case, the tire may explode when
using the emergency tire puncture repair kit, resulting in death or serious
injury.
