To inject the sealant and inflate the
tire, turn the compressor switch on.
13
Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and the
pressure will spike to between 300
kPa (3.0 kgf/cm

or bar, 44 psi)
and 400 kPa (4.0 kgf/cm
2
or bar,
58 psi), then gradually decrease.
The air pressure gauge will display
the actual tire inflation pressure
about 1 to 5 minutes after the
switch is turned on.
Turn the compressor switch off and then
check the tire inflation pressure. Being
careful not to over inflate, check and
repeat the inflation procedure until the rec-
ommended tire inflation pressure is
reached.
If the tire inflation pressure is still lower than
the recommended level after inflation for
25 minutes with the switch on, the tire is
too damaged to be repaired. Turn the com-
pressor switch off and contact any author-
ized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.

WARNING
■
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.
438
7-2. 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 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 40 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 130 kPa (1.3 kgf/cm2 or
bar, 19 psi) 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 repair kit directly onto
dusty ground such as sand at the side
of the road. If the repair 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.
●

To avoid damage to the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and
transmitter may not operate properly. If a
liquid sealant is used, contact any author-
ized Lexus retailer or Lexus authorized
repairer, or any reliable repairer or other
qualified service shop as soon as possi-
ble. After use of liquid sealant, make sure
to replace the tire pressure warning valve
and transmitter when repairing or
replacing the tire. (

Failure to do so may result in serious
injury:
• Do not try to remove the wheel orna-
ment by hand. Take due care in han-
dling the ornament to avoid
unexpected personal injury.
• Do not touch the disc wheels or the
area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the
disc wheels and the area around the
brakes will be extremely hot. Touching
these areas with hands, feet or other

may result in burns.
●
Failure to follow these precautions
could cause the wheel nuts to loosen
and the tire to fall off, resulting in death
or serious injury.
• Never use oil or grease on the wheel
bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In
addition, the oil or grease can cause
the wheel nuts to loosen and the wheel
may fall off, causing an accident and
resulting in death or serious injury.
Remove any oil or grease from the
wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a
torque wrench to 103 N•m (10.5
kgf•m, 76 ft•lbf) as soon as possible
after changing wheels.
• When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer.
• Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
