5-2. Steps to take in an emergency
Before putting the sealant into useCheck the degree of tire damage befo re making use of the sealant in the
emergency tire puncture repair kit.
A tire should only be repaired if the
damage is caused by a nail or
screw passing through the tire
tread.
Do not remove the nail or screw
from the tire.
Move the vehicle until the area of
the puncture, if known, is posi-
tioned at the bottom, in contact
with the ground. This allows the
sealant to plug the damaged area
more effectively.
Emergency repair with the sealant in the kit is not possible in the following
cases. Contact your Lexus dealer.
● When the wheel is damaged
● When two or more tires have been punctured
● When the tire is damage d due to driving without sufficient tire inflation
pressure
● When the tire is visibly disengaged from the wheel
● When the tire lost air pressure due to a crack or damage in the tire
sidewall
● When the cut or piercing to the tread is 0.16 in. (4 mm) or more
