■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 wi th 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 re paired, as there is a chance of it bursting
while the repair operation is being perfor med. 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 35 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 airbag 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 19 psi (130 kPa, 1.3 kgf/cm
2 or
bar) 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 possible.
●The kit is not waterproof. Make sure that th e 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.
●Make sure to stand the kit with the bottle ve rtical. 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 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 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 pressu re warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and trans-
mitter may not operate properly. If a liquid se alant is used, contact your Lexus dealer as
soon as possible. Make sure to replace the tire pressure warning valve and transmitter
when replacing the tire. ( P. 4 9 2 )
