●Stop the vehicle in a safe place on a hard, flat surface.
●Set the parking brake.
●Shift the shift lever to P.
●Stop the engine.
●Turn on the emergency flashers. (P. 580)
●Check the degree of the tire damage.
A tire should only be repaired with the
emergency tire puncture repair kit if
the damage is caused by a nail or screw
passing through the tire tread.
• Do not remove the nail or screw
from the tire. Removing the object
may widen the opening and
disenable emergency repair with the
kit.
• To avoid sealant leakage, move the vehicle until the area of the puncture, if
known, is positioned at the top of the tire.
■A flat tire that cannot be repaired with the emergency tire puncture repair kit
In the following cases, the tire cannot be repaired with the emergency tire puncture repair kit. Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●When the tire is damaged due to driving without sufficient air pressure
●When the tire lost air pressure due to a crack or damage in the tire sidewall
●When the tire is visibly separated from the wheel
●When the cut or damage to the tread is 4 mm (0.16 in.) long or more
●When the wheel is damaged

RC200t_RC F_EE(OM24728E)
Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and
the pressure will spike to 300 kPa
(3.0 kgf/cm2 or bar, 44 psi) or
400 kPa (4.0 kgf/cm2 or bar, 58
psi), 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 inflationpressure. 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 the compressor switch off and contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
• If the tire inflation pressure exceeds th e recommended level, let out some air to adjust the tire inflation pressure.
( P. 645, 679)
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 wh en 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.

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 130 kPa (1.3 kgf/cm
2 or

rized Lexus dealer or repairer, or
another duly qualified and
equipped professional.
If the tire inflation pressure is between 130 kPa (1.3 kgf/cm
2 or bar, 19 psi)
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 infl ate the tire until the recommended tire
inflation pressure is reached. Drive for about 5 km (3 miles) and then perform
step .

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 inburns.
●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.
• 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 completed, 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 performe d. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repair operation immedi- ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 35 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and after operation. Do not touch the metal part around the connecting area between the
bottle and compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one indi- cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may preven t 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 cor-
nering.
●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 separated from the wheel. • Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm2 or b ar, 1 9 p si)or below, this may indica te severe tire damage.
