5-2. Steps to take in an emergency
■Sealant
●One tire can be repaired using the bottle of sealant stored in the emergency tire
puncture repair kit.
●The sealant can be used when the outside temperature is from -22°F (-30°C)
to 140°F (60°C).
●When the outside temperature is low, the viscosity of the sealant becomes high
and it will be more difficult to inject th e sealant. In this case, warm the sealant in
the vehicle before using it.
●The sealant has a limited lifespan. The expi ration date is marked on the bottle.
The sealant should be replaced before the expiration date. Contact your Lexus
dealer.
●If the sealant gets on your clothes, it may stain.
●After using the sealant, bring the empty bottle of sealant to your Lexus dealer
and purchase a new bottle. Keep the ne w bottle of sealant in your vehicle.
■Compressor
●The compressor is a pneumatic filling type for passenger vehicles.
●When the compressor is operating, a loud operating noise will be produced.
This does not indicate a malfunction.
■The wheel of a tire that has been repaired
If you remove the sealant adhering to the wheel with a rag, you can reuse the wheel.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the tire pres-
sure warning valve and transm itter should be replaced.
●After a tire is repaired with the emergency tire puncture repair kit, even if the
tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.

5-2. Steps to take in an emergency
CAUTION
■Precaution for children
Keep the emergency tire puncture repair kit out of the reach of children and store it
properly.
■Sealant precautions
●The sealant in the emergency tire puncture repair kit is not for human consump-
tion.
If the sealant is consumed, drink a large quantity of water and get medical atten-
tion immediately.
●If sealant gets in your eyes or on your skin, thoroughly wash with a large quantity
of water. If necessary, get medical attention.
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●If force is used to turn the valve core tool while air remains in the tire, special care
should be taken because the valve core could fly out.
●Be careful, as sealant may fly out if you shake the bottle with the hose installed.
●If the hose is not securely installed, sealant may leak out when filling.
●Connect the valve and hose securely with the tire installed on the vehicle.
●Be careful handling the compressor, as parts of the compressor get hot during
operation. Some parts of the compressor may remain hot after use.
●Do not attach the vehicle speed warning sticker to an area other than the one
indicated. If the sticker is attached to an area where an SRS airbag is located,
such as the pad of the steering wheel, it may prevent the SRS airbag from operat-
ing properly.
■Driving to spread the liquid sealant evenly
Drive cautiously at a moderate speed, avoi ding sudden starts, sudden braking, and
abrupt steering maneuvers.

6-1. Specifications
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and
they represent the tire's ability to stop on wet pavement as measured
under controlled condit ions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turning) trac-
tion.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Mo tor Vehicle Safety Standard No. 139.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excess ive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
