If you have a flat tire (vehicles with emergency tire

emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be
repaired temporarily with the em ergency tire puncture repair kit.

Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel beyond
repair, which could result in an accident.

Remove the 12-volt battery cover.

Check the degree of the tire damage.
A tire should only be repaired with the

may widen the opening and disen-
able emergency repair with the kit.
