Inflate the tire until the recom- 
mended pressure is reached.
The sealant will be injected and the
pressure will spike to 300 kPa 
(3.0 kgf/cm 2
 or bar, 44 psi) or
400 kPa (4.0 kgf/cm 2
 or bar, 58
psi), and then gradually decrease. 
The air pressure gauge will dis- 
play the actual tire inflation pres- 
sure about 1 minute (15 minutes at 
low temperature) after the switch 
is turned on. 
Inject to recommended pressure.

Attach the air release cap to the end 
of the hose. 
If the air release cap is not attached, the 
sealant may leak and the vehicle may
get dirty. 
Temporarily store the bottle in the trunk while it is connected to the compres- 
sor. 
To spread the liquid sealant evenly within the tire, immediately drive safely for 
about 5 km (3 miles) below 80 km/h (50 mph). 
After driving for about 5 km 
(3 miles), stop your vehicle in a safe 
place on a hard, flat surface and 
remove the air release cap from the 
hose before reconnecting the repair 
kit. 
Turn the compressor switch on and 
wait for several seconds, and then 
turn it off. Check the tire inflation 
pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm 2
 or
bar, 19 psi): The puncture cannot
be repaired. Contact any autho- 
rized Lexus retailer or Lexus 
authorized repairer, or any reli- 
able repairer. 
If the tire inflation pressure is 130 kPa (1.3 kgf/cm 2
 or bar, 19 psi) or higher,
but less than the recommended level: Proceed to step  .
If the tire inflation pressure is the recommended level: Proceed to step  .15

■Emergency tire puncture repair kit
●The sealant has a limited lifespa n. The expiry date is shown on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus retailer or 
Lexus authorized repairer, or any  reliable repairer 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 has been used and need to be purchased,
contact any authorized Lexus retailer or  Lexus authorized repairer, or any reliable
repairer.
●The sealant can be used when the outside temperature is from -40  C (-40  F) to
60 C (140  F).
●The repair kit is exclusively designed for size  and type of tires originally installed on your
vehicle. 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 repair kit, a loud  operation noise is produced. This does not
indicate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire pres- 
sure.
■If the tire is inflated to mo re than the recommended level
Disconnect the hose from the valve. 
Disconnect the hose from the valve, remove the air release cap from the hose and then 
reconnect the hose. 
Turn the compressor switch on and wait for se veral seconds, and then turn it off. Check
that the air pressure indicator shows the recommended level. ( P. 629)
If the air pressure is lower than the reco mmended level, turn the compressor switch on
again and repeat the inflation procedure un til the recommended pressure is reached.
Install the air release cap to the end of the 
hose and push the protrusion on the air 
release cap into the tire valve to let some air
out.

■After a tire is repaired with the  emergency tire puncture repair kit
●The tire pressure warning valve an d transmitter should be replaced.
●Vehicles with the tire pressure warning system: Even if the tire inflation pressure is at the 
recommended level, the tire pressure warning light may come on/flash.
■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.
WARNING
■Caution while driving 
Observe the following precautions. 
Failure to do so may cause an accident.
●The emergency tire puncture repair kit is made exclusively for your vehicle. Do not 
use it on other vehicles.
●Do not use the emergency tire puncture repair kit for tires that are a different size 
than the specified ones or fo r any other purpose. Doing so may cause the tires to not
be repaired properly.
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant, consume as 
much water as possible, and then immediately consult a doctor.

WARNING
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around  the brakes immediately after the vehicle
has been driven. 
After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other bo dy parts may result in
burns.
●Connect the valve and hose securely with the tire installed on the vehicle.
●If the hose is not properly connected to the valve, air leakage may occur or sealant 
may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will 
move abruptly due to air pressure.
●After inflation of the tire has completed, the sealant may splatter when the hose is dis- 
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not followed, the 
sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it bursting 
while the repair operation is being performe d. If you notice any cracks or deforma-
tion of the tire, turn off the compressor switch and stop the repair operation immedi-
ately.
●The repair kit may overheat if operated for a long period of ti me. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during op eration. Be careful handling the repair kit
during and after operation. Do not touch the metal part connecting the bottle and the 
compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one indi- 
cated. 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 air bag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be  especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop 
the vehicle and check the following:
