mended level: The tire can
be repaired. Proceed to step
.
If the tire inflation pressure
is at the recommended
level: Proceed to step .
Turn the compressor switch on to inflate the tire until the recom-
mended tire inflation pressure is reached. Drive for about 5 km (3

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
When two or more tires have been punctured
When there is more than one hole or cut in the damaged tire
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 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 in the bottle and other
parts of the kit have been used and need to be purchased, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
The sealant can be used when the outside temperature is from -30 C (-22
F) to 60 C (140 F).
The 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 kit, a loud operation noise is produced. This does
not indicate a malfunction.

When trouble arises

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, then turn it
off. Check that the air pressure indicator shows the recommended level.
(P. 850)
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. 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.
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, then immediately consult a doctor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.

CAUTION
When fixing the flat tire
Stop your vehicle in a safe and flat area.
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.
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 kit may overheat if operated for a long period of time. Do not operate
the compressor continuously for more than 10 minutes.
Parts of the kit become hot during operation. Be careful handling the kit
during and after operation.
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.
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 below, this may indicate 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 pos-
sible.
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 kit, 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 transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (P. 674)
