In the following cases, the tire cannot be repaired with the emergency tire punc-
ture 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 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 -30C (-22F) to
60C (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
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.

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. 570)
If the air pressure is lower than the recommended level, turn the compressor
switch on again and repeat the inflation procedure until the recommended pres-
sure 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
Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
The emergency tire puncture repair kit is made exclusively for your vehicle.
Do not use it on other vehicles.
Do not use the emergency tire puncture repair kit for tires that are a different
size than the specified ones or for any other purpose. Doing so may cause the
tires to not be repaired properly.
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant, con-
sume 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.

Run-flat tires (A “RFT” or “DSST” mark is molded on the sidewall)
Take your vehicle to the nearest
Lexus dealer or authorized tire
dealer as soon as possible if any
tire goes flat.
The vehicle can be driven for a
maximum of 300 km (186 miles)
at a speed below 60 km/h (37
mph) after the tire pressure warn-
ing light comes on. (P. 510)
In some conditions (such as at high temperatures)
You cannot continue driving for up to 300 km (186 miles).
For the detailed information on run-flat tires
See the tire warranty booklet.
If you have a flat tire (vehicles with run-flat tires)
You can continue driving a vehicle with run-flat tires even if any tire
goes flat.In this case, slow down and drive with extra caution.
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
replace the tire pressure warning valve and transmitter when replacing the tire.
