RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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/cm 2
or
bar), 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. • 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 lo wer than the recommen ded level after infla-
tion for 10 minutes (35 minutes at low temperature) with the switch on, the tire
is too damaged to be repaired. Turn th e compressor 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. 513, 548)
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 valv e 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). 13

When trouble arises After driving, stop your vehicle in a
safe place on a hard, flat surface and
reconnect the compressor.
Turn the compressor switch on and
wait for several seconds, then turn it
off. Check the tire inflation pressure.
If the tire inflation 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 leve l: The tire can be repaired. Pro-
ceed to step .
If the tire inflation pressure is at 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
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.19
