Disconnect the hose from the valve.
Disconnect the hose from the valv e, remove the air release cap from
the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then
turn it off. Check that the air pressure indicator shows the sp ecified air
pressure. ( P. 725)
If the air pressure is under the designated pressure, turn the compres-
sor switch on again and repeat the inflation procedure until th e speci-
fied air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repai r kit, the

■After a tire is repaired with the emergency tire puncture repai r kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire
pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.

●The sealant has a limited life span. The expiry date is marked on the
bottle. The sealant should be repl aced before the expiry date. Contact
your Toyota dealer for replacement.
●The sealant stored in the emergency tire puncture repair kit ca n be used
only once to temporarily repair a single tire. If the sealant i n the bottle
and other parts of t he kit have been used a nd need to be replaced, con-
tact your Toyota dealer.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -4 0°F
(-40°C) to 140°F (60°C).
●The kit is exclusively designed for size and type of tires orig inally
installed on your vehicle. Do not use it for tires that a diffe rent 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. Immedi ately wipe
away the sealant with a wet cloth.
●During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
●Do not use to che ck or to adjust the tire pressure.

When trouble arises
WARNING
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side
wall. In such a case, the tire may explode when using a repair kit.
■Caution while driving
●Store the repair kit in the luggage compartment.
Injuries may result in the event of an accident or sudden braki ng.
●The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
●Do not use repair kit for tires that are different size than the original
ones, or for any other purpose. If the tires have not been comp letely
repaired, it could le ad to an accident causing death or serious injury.
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a

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 immediate ly
after the vehicle has been driven.
After the vehicle has been driven, the wheels and the area arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on the vehi-
cle. If the hose is not properly connected to the valve, air le akage may
occur as 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 spla tter when
the hose is disconnec ted or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the proce dures 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. I f you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
●The repair kit may overheat if operated for a long period of ti me. Do not
operate the repair kit continuous ly for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the met al part
connecting the bottle and the compressor. It will be extremely hot.
●Do not attach the vehicle speed warning 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 ma y prevent
the SRS airbag from operating properly.

When trouble arises
WARNING
■Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and ca use death
or serious injury.
●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 throu gh the
steering wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 p si
(130 kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely dam-
aged.
NOTICE
■When performing an emergency repair
●A tire should only be repaired with the emergency tire puncture repair
kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread.
Do not remove the sharp object from the tire. Removing the obje ct may
widen the opening and disenable e mergency repair with the repair kit.
●The repair kit is not waterproof. Make sure that the repair 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 sa nd at the
side of the road. If the repair kit vacuums up dust etc., a mal function
may occur.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehi cle
use. Do not connect the repa ir kit to any other source.
●If fuel splatters on the repair kit, the repair kit may deterio rate. Take
care not to allow fuel to contact it.
●Place the repair kit in a storage to prevent it from being exposed to dirt
or water.
●Store the repair kit in the luggage compartment out of reach of chil-
dren.
●Do not disassemble or modify the repair kit. Do not subject par ts such
as the air pressure indicator to impacts. This may cause a malfunction.
