RC350_RC300 AWD_RC300_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/cm2 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 recommended 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 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).

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 level: 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.

■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is marked on the bottle. The sealant
should be replaced before the expiry date. Contact your Lexus dealer for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to
temporarily repair a single tire. If the sealant has been used and needs to be purchased,
contact your Lexus dealer. The compressor is reusable.
●The sealant can be used when the outside temperature is from -40 F (-40 C) to
140 F (60 C).
●The kit is exclusively designed for size and type of tires originally installed on your vehi-
cle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on yo ur 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 operation noise is produc ed. This does not indicate a
malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire pres-
sure.
