Start the hybrid system.
To inject the sealant and inflate the
tire, turn the compressor switch on.
Inflate the tire until the specified air
pressure is reached.
The sealant will be injected and
the pressure will surge and then
gradually decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 minute (5 minutes at
low temperature) after the switch
is turned on.
Inflate the tire until the specified
air pressure.
• Turn the compressor switch off
and then check the tire infla-
tion pressure. Being careful
not to over inflate, check and
repeat the inflation procedure
until the specified tire inflation
pressure is reached.
• If the tire inflation pressure is still lower than the specified point after
inflation for 35 minutes with the swit ch on, the tire is too damaged to be
repaired. Turn the compressor swit ch off and contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
• If the tire inflation pressure exceed s the specified air pressure, let out
some air to adjust the tire inflation pressure. ( P. 622, 652)

■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 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 in the bottle and other parts of the kit have been used and need to be purchased, cont act any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
●The sealant can be used when the outside temperature is from -30C (-22F) to 60C (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 yo ur 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. I mmediately 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.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●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.

■If the tire is inflated to more 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, then turn it off. Check that the air pressure indicator sh ows the recommended level. (P. 652)
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 valve to let some air out.
WARNING
■Caution while driving
Observe the following precautions. Failure to do so may cause an accident.
●The emergency tire puncture re pair kit is made exclusively for your vehicle. Do not
use it on other vehicles.
●Do not use the emergency tire puncture repa ir kit for tires that are a different size
than the specified ones or for any other pu rpose. Doing so may cause the tires to not
be repaired properly.
■Precautions for use of the sealant
●Ingesting the sealant is haza rdous to your health. If you ingest sealant, consume as
much water as possible, 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 body parts may result in
burns.
●Connect the valve and hose securely wi th 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 ha s 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 procedure is not followed, the
sealant may spray out.
●Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repair operation immedi- ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 10 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and
after operation.
●Do not attach the vehicle speed warning stic ker 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:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire infl ation pressure is 130 kPa (1.3 kgf/cm2 or bar, 19 psi) or below, this may indi cate severe tire damage.

NOTICE
■When performing an emergency repair
●Perform the emergency repair without removing the nail or screw that has punctured
the tread of the tire. If the object that has punctured the tire is removed, repair by the
emergency tire puncture repair kit may not be possible.
●The kit is not waterproof. Make sure that the kit is not exposed to water, such as when
it is being used in the rain.
●Do not put the kit directly onto dusty ground such as sand at the side of the road. If the kit vacuums up dust etc., a malfunction may occur.
●Use the kit with the top facing upward. The kit cannot work properly if it is laid on its
side.
■Handling the emergency tire puncture repair kit
●The compressor power source should be 12 V DC suitable for vehicle use. Do not
connect the compressor to any other source.
●If gasoline splatters on the ki t, the kit may deteriorate. Take care not to allow gasoline
to contact it.
●Store the kit in its assigned place out of reach of children.
●Do not disassemble or modify the kit. Do not subject parts such as the air pressure
indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants , the tire pressure warning valve and trans-
mitter may not operate properly. If a liqui d sealant is used, contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible. After use of liquid sealant, make sure to replace the tire pressure warning valve and
transmitter when repairing or replacing the tire. (P. 526)
