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 luggage compartment 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 for about 5 km (3
miles), stop your vehicle in a safe
place on a hard, flat surface and
remove the air release cap from
the hose before reconnecting the
repair kit.

Turn the compressor switch on
and wait for an approximately 5
seconds, and then turn it off.
Check the tire inflation pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi): The puncture cannot
be repaired. Contact any autho-
rized Lexus dealer or repairer, or
another duly qualified and
equipped professional.
If the tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or bar, 19 psi) or
higher, but less than the specified air pressure: Proceed to .
If the tire inflation pressure is the specified air pressure (P. 570): Pro-
ceed to .
Turn the compressor switch on to inflate the tire until the specified air
pressure is reached. Drive for about 5 km (3 miles) and then perform
.
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.
Store the bottle in the luggage compartment 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 the nearest
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for tire repair or replacement.

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.

When trouble arises
IS300h_EE(OM53B95E)
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.

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.
