When trouble arises
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 temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.) After tempor ar-
ily repairing the tire with the kit, have the tire repaired or
replaced by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
Q If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the t ire and the
wheel beyond repair, which could result in an accident.
