Check the specified tire inflation
pressure.
Tire inflation pressure is specified on the
label as shown. (P. 532)
Start the engine. ( P. 203)
To inject the sealant and inflate the
tire, turn the compressor switch on.
Inflate the tire until the recom-
mended pressure is reached. The sealant will be injected and
the pressure will spike to 44 psi
(300 kPa, 3.0 kgf/cm
2 or bar) or
58 psi (400 kPa, 4.0 kgf/cm2 or
bar), and then gradually
decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 minute (15 minutes at
low temperature) after the switch
is turned on.
Inject to recommended pressure.
• Turn the compressor switch off and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat the
inflation procedur e until the spec-
ified tire inflation pressure is
reached.

When trouble arises
• If the tire inflation pressure is still lower than the specified po int after inflation for
10 minutes (35 minutes at low temperature) with the switch on, the tire is too
damaged to be repaired. Turn the co mpressor switch off and contact your
Lexus dealer.
• If the tire inflation pressure exceeds th e recommended level, let out some air to
adjust the tire inflation pressure. ( P. 497, 532)
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 trunk while it is connected to the compres-
sor.
To spread the liquid sealant evenly within the tire, immediately drive safely for
about 3 miles (5 km) below 50 mph (80 km/h).
After driving for about 3 miles
(5 km), 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 several seconds, and then
turn it off. Check the tire inflation
pressure.If the tire inflation pressure is under
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 19 psi (130 kPa, 1.3 kgf/cm
2 or bar) or higher,
but less than the recommended level: Proceed to step .
If the tire inflation pressure is the recommended level: Proceed to step .
Turn the compressor switch on to inflate the tire until the recommended tire
inflation pressure is reached. Drive for about 3 miles (5 km) and then perform
step .
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 trunk while it is connected to the compressor.
Taking precautions to avoid sudden br aking, sudden acceleration and sharp
