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 authorized Lexus
dealer or repairer, or another duly qualified and equipped professional 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 authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
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.
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.
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.

When trouble arises

CAUTION
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 procedure is 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 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 replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve
and transmitter, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional as the tire pressure warning valve and
transmitter may be damaged if not handled correctly.
When driving over bumps
If a vehicle has a flat tire, the vehicle height will be lower than usual. Ensure
that nothing strikes the bottom of the vehicle.
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 or other qualified service shop as soon as possible. Make sure to
