■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is marked on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to
temporarily repair a single tire. If the sealant in the bottle and other parts of the kit have
been used and need to be purchased, contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
●The sealant can be used when the outside temperature is from -30°C (-22°F) to 60°C
(140°F).
●The kit is exclusively designed for size and type of tires originally installed on your vehi-
cle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet
cloth.
●During operation of the kit, a loud operation noise is produced. This does not indicate a
malfunction.
■The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the valve should be
replaced.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry date has already
passed. Otherwise, repairs conducted using the emergency tire puncture repair kit may
not be performed properly.
