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 opera-
tion 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.
■Note for checking the emergency tire
puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do

Turn the compressor switch off and then
check the tire inflation pressure. Being
careful not to over inflate, check and
repeat the inflation pr ocedure until the rec-
ommended tire inflation pressure is
reached.
If the tire inflation pre ssure is still lower than
the recommended level after inflation for
10 minutes (35 minutes at low tempera-
ture) with the switch on, the tire is too dam-
aged to be repaired. Turn the compressor
switch off and contact your Lexus dealer.
If the tire inflation pressure exceeds the
recommended level, let out some air to
adjust the tire inflation pressure. ( P.327,
347)
14 With the compressor switch off, dis-
connect 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.
15Install the valve cap onto the valve
of the emergency repaired tire.
16 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.
17Temporarily store the bottle in the
trunk while it is connected to the
compressor.
18 To spread the liquid sealant evenly
within the tire, immediately drive safely for about 3 miles (5 km)
below 50 mph (80 km/h).
19 After driving, stop your vehicle in a
safe place on a hard, flat surface
and reconnect the compressor.
20 Turn the compressor switch on and
wait for several seconds, then turn it
off. Check the tire inflation pres-
sure.
If the tire inflatio n pressure is below
19 psi (130 kPa, 1.3 kgf/cm
2 or bar):
The puncture cannot be repaired.
Contact your Lexus dealer.
If the tire inflation pressure is
between 19 psi (130 kPa, 1.3
kgf/cm
2 or bar) and a point below
the recommended level: The tire
can be repaired. Proceed to step

23Store the bottle in the trunk while it
is connected to the compressor.
24 Taking precautions to avoid sud-
den braking, sudd en acceleration
and sharp turns, drive carefully at
under 50 mph (80 km/h) to your
Lexus dealer that is less than 62
miles (100 km) away for tire repair
or replacement.
■After a tire is repaired with the emer-
gency tire puncture repair kit
●The tire pressure warning valve and
transmitter should be replaced.
●Even if the tire inflat ion pressure is at the
recommended level, the tire pressure
warning light may come on/flash.
■If the tire is inflated to more than the
recommended level
1 Disconnect the hose from the valve.
2 Install the air release cap to the end of
the hose and push th e protrusion on the air release cap into the valve to let some
air out.
3 Disconnect the hose from the valve,
remove the air release cap from the
hose and then reconnect the hose.
4 Turn the compressor switch on and wait
for several seconds, then turn it off.
Check that the air pressure indicator
shows the recommended level.

If the air pressure is lower than the rec-
ommended level, turn the compressor
switch on again and repeat the inflation
procedure until the recommended
pressure is reached.
WARNING
■When fixing the flat tire
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●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.

3287-2. Steps to take in an emergency
WARNING
• 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 com- pleted, 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
followed, the sealant may spray out.
●Keep back from the tire while it is
being repaired, as th ere 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 35 minutes.
●Parts of the kit become hot during
operation. Be careful handling the kit
during and after operation. Do not
touch the metal part around the con-
necting area between the bottle and
compressor. It will be extremely hot.
●Do not attach the vehicle speed warn-
ing 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 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 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 sepa- rated 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 with-
out 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 possi-
ble.
●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.
●Make sure to stand the kit with the bot-
tle vertical. The kit cannot work prop-
erly if it is laid on its side.
■Handling the emergency tire punc-
ture 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.
