Connect the injection hose by
screwing it onto the bottle. As it is
screwed in, the aluminum seal on
the bottle will be torn.
Remove the plug from the injection
hose.
Connect the injection hose to the
valve.

5-2. Steps to take in an emergency
Check the specified inflation pressure. (P. 366)
Turn the compressor switch “ON”
and fill the tire with air until the
specified inflation pressure is
reached.
Turn the switch “OFF” when the
pressure gauge connected to the
hose reads the specified pressure.
If the inflation pressure is not
attained within 8 minutes, emer-
gency repair is not possible due to
severe damage. Contact your
Lexus dealer.
After completely filling the tire with air, disconnect the hose from
the tire valve and the compress or power plug from the power
outlet.
To spread the liquid sealant ev enly in the tire, immediately drive
for about 3 miles (5 km) or 10 minutes.
Drive cautiously at a moderate speed, avoiding sudden starts, sudden
braking, and abrupt steering maneuvers.
After driving about 3 miles (5 km)
or 10 minutes, stop your vehicle in
a safe place and reconnect the
compressor.

5-2. Steps to take in an emergency
Read the inflation pressure on the
pressure gauge.
If the pressure is 18 psi (130 kPa,
1.3 kgf/cm
2 or bar) or above:
Fill the tire with air using the com-
pressor until the specified inflation
pressure is reached.
If the pressure is less than 18 psi
(130 kPa, 1.3 kgf/cm
2 or bar):
The emergency repair that has
been performed is not safe for use
as damage to the ti re is too severe.
Do not continue to drive the vehi-
cle. Contact your Lexus dealer.
Store the kit and then attach the
sticker as shown.
Taking precautions to avoid sud-
den braking and sharp turns, drive
carefully at under 50 mph (80
km/h) to the nearest Lexus dealer
or tire dealer for tire repair or
replacement.

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.

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.

NOTICE
■Vehicles with a flat tire
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.
■When performing an emergency repair
Perform the emergency repair without removing the nail or screw that has punc-
tured the tread of the tire. If the object th at has punctured the tire is removed, the
repair using the sealant in the emergenc y tire puncture repair kit may fail.
■When fixing the flat tire
●Do not put the valve core on dirty ground or in the sand.
Store it in a clean place.
●Do not remove the inside cap of the sealant bottle.
●Turn the valve core tool with your hand when screwing it in. If you use another tool
in conjunction with the valve core tool, damage may occur.
●Do not operate the compressor continuously for more than 10 minutes. The
motor may overheat and be damaged. Le t the compressor cool before using it
again.
■Compressor precautions
●The compressor power source should be 12 V DC suitable for vehicle use.
Do not connect the compressor to 24 V DC or any other power source.
●The compressor is an oil-less type. Do not lubricate with oil.
●If the compressor does not operate properly or becomes hot, it may be over-
heated. Turn off the switch and leave the compressor to cool down for at least 30
minutes.
●The compressor is not waterproof. Make sure that the compressor is not exposed
to water, such as when it is being used in the rain.
●Do not put the compressor directly onto dusty ground such as sand at the side of
the road. If the compressor vacuums up dust etc., a malfunction may occur.
●Do not disassemble or modify the compre ssor. Do not subject parts such as the
air pressure indicator to impacts. This may cause a malfunction.
