Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and
the pressure will spike to between
300 kPa (3.0 kgf/cm2 or bar, 44
psi) and 400 kPa (4.0 kgf/cm2 or
bar, 58 psi), then gradually
decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 to 5 minutes after the
switch is turned on.
• 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 recommended tire
inflation pressure is reached.
• If the tire inflation pressure is still lower than the recommended level
after inflation for 25 minutes with the switch on, the tire is too damaged
to be repaired. Turn the compressor switch off and contact any autho-
rized 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. 704)
With the compressor switch off, disconne ct the hose from the valve on the tire
and then pull out the power plug from the power outlet socket.
Some sealant may leak wh en the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.

To spread the liquid sealant evenly within the tire, immediately drive safety for
about 5 km (3 miles) below 80 km/h (50 mph).
After driving, stop your vehicle in a
safe place on a hard, flat surface and
reconnect the compressor.
Turn the compressor switch on and
wait for several seconds, then turn it
off. Check the tire inflation pressure.
If the tire inflation pressure is
below 130 kPa (1.3 kgf/cm2 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 between 130 kPa (1.3 kgf/cm2 or bar, 19 psi)
and a point below the recommended level: The tire can be repaired. Pro-
ceed to step .
If the tire inflation pressure is at the recommended level: Proceed to step
.

■Emergency tire puncture repair kit
●The sealant has a limited life span. The expiry date is marked on the bottle. The sealant should be replaced before the expiry da te. Contact any authorized Lexus dealer or repairer, or another duly qualified an d 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 seal ant has been used and needs to be purchased, contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. The compressor is reusable.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -40 C (-40F) to 60C
(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 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 kit, a loud operatio n noise is produced. This does not indicate a
malfunction.
●Do not use to check or to adjust the tire pressure.
■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 several seconds, then turn it off. Check that
the air pressure indicator sh ows the recommended level. (P. 737) 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.
■After a tire 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.
Install the air release cap to the end of the

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 beextremely hot. Touching these areas with hands, feet or other body 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 procedure is 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 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 40 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and after operation. Do not touch the metal part around the connecting area between the
bottle and 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:
• Tire condition. The tire may have separated from the wheel. • Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm2 or b ar, 1 9 p si)or below, this may indica te severe tire damage.
