With the compressor switch off, disconnect the hose from the valve on
the tire and then pull out the power plug from the power outlet socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.
Attach the air release cap to the
end of the hose.
If the air release cap is not attached,
the sealant may leak and the vehicle
may get dirty.
Temporarily store the bottle in the trunk while it is connected to the
compressor.
To spread the liquid sealant evenly within the tire, immediately drive
safely 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.

Store the bottle in the trunk while it is connected to the compressor.
Taking precautions to avoid sudden braking, sudden acceleration and
sharp turns, drive carefully at under 80 km/h (50 mph) to any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional that is less than 100 km (62 miles) away for tire repair or
replacement.
■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is marked on the bottle. The seal-
ant should be replaced before the expiry date. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional for replace-
ment.
●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 needs to be pur-
chased, contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional. The compressor is reusable.
●The sealant can be used when the outside temperature is from -40 C (-40F) to
60 C (140F).
●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 indi-
cate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire
pressure.

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 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.
■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 gas-
oline 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 pres-
sure 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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. After use of liquid sealant,
make sure to replace the tire pressure warning valve and transmitter when repair-
ing or replacing the tire. ( P. 508)
