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
display the actual tire infla-
tion pressure about 1 minute
(15 minutes at low tempera-
ture) 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,

When there is more than one hole or cut in the damaged tire
When the sealant has expired
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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional 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 pressure.

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. 936)
If the air pressure is lower than the recommended level, turn the compres-
sor switch on again and repeat the inflation procedure until the recom-
mended pressure is reached.
The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the valve
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.
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.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.

CAUTION
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 doc-
tor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
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 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 disconnected or some air is let out of the tire.
Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, 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 performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 35 minutes.
Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the metal part con-
necting 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 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 air
bag from operating properly.

CAUTION
Driving to spread the liquid sealant evenly
Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
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/cm
2
or bar, 19 psi) or less, the tire may be severely damaged.
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 pos-
sible.
The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction may
occur.
