Check the degree of the tire damage.
A tire should only be repaired with the
emergency tire puncture repair kit if
the damage is caused by a nail or screw
passing through the tire tread.• Do not remove the nail or screw
from the tire. Removing the object
may widen the opening and disen-
able emergency repair with the kit.
• To avoid sealant leakage, move the vehicle until the area of the puncture, if known, is positioned at the top of the tire.
Remove the valve cap from the valve
of the punctured tire.
Remove the air release cap from the
hose.
You will use the air release cap again.
Therefore keep it in a safe place.

Check the specified tire inflation
pressure.

GS450h_300h_OM_OM30F00E_(EE)
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/cm2 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.
• Turn the compressor switch off and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat the
inflation procedure until the spec-
ified tire inflation pressure is
reached.
• If the tire inflation pressure is still lower than the specified point after inflation for 10 minutes (35 minutes at low temperature) with the switch on, the tire is too
damaged to be repaired. Turn the compressor switch off and contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
• If the tire inflation pressure exceeds the recommended level, let out some air to
adjust the tire inflation pressure. ( →P. 5 3 9 , 5 7 5 )
With the compressor switch off, disconnect the hose from the valve on the tire
and then pull out the power plug from the power outlet socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.

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 dealer or repairer, or
another duly qualified and
equipped professional.
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 .

Turn the compressor switch on to inflate the tire until the recommended tire
inflation pressure is reached. Drive for about 5 km (3 miles) and then perform
step .
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.
Store the bottle in the trunk while it is connected to the compressor.
Taking precautions to avoid sudden braking, sudden acceleration and sharp
turns, drive carefully at under 80 km/h (50 mph) to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional that is
less than 100 km (62 miles) away for tire repair or replacement.
■In the following cases, the tire cannot be repaired with the emergency tire puncture
repair kit. Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
●When the tire is damaged due to driving without sufficient air pressure
●When the tire lost air pressure due to a crack or damage in the tire sidewall
●When the tire is visibly separated from the wheel
●When the cut or damage to the tread is 4 mm (0.16 in.) long or more
●When the wheel is damaged

■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is shown 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 has 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 -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 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 several seconds, and then turn it off. Check
that the air pressure indicator shows the recommended level. ( →P. 5 7 5 )
If the air pressure is lower than the recommended level, turn the compressor switch on
again and repeat the inflation procedure until 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 and 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.

■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

●Do not use the emergency tire puncture repair kit for tires that are a different size
than the specified ones or for 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.
●If sealant gets in eyes or adheres to skin, i mmediately wash it off with water. If discom-
fort persists, consult a doctor.
