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 doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with water. If dis-
comfort 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 seal-
ant 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 followed,
the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it burst-
ing 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 opera-
tion 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 connecting 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 operat-
ing 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 punc-
tured 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 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.
■Handling the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not
connect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate. Take care not
to allow gasoline to contact it.
●Store the emergency tire puncture repair kit in the trunk.
The kit may be thrown around during sudden braking and so forth, damaging the
kit.
●Store the repair kit in the trunk out of reach of children.
●Do not disassemble or modify the repair 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 (vehicles
with the tire pressure warning system)
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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (→P. 4 6 8 )
