5-2. Steps to take in an emergency
Inflate the tire until the specified
air pressure is reached.
The sealant will be injected
and the pressure will spike to
44 psi (300 kPa, 3.1 kgf/cm
2
or bar) or 58 psi (400 kPa, 4.1
kgf/cm2 or bar), and then
gradually decrease.
The air pressure gauge will
display the actual tire inflation
pressure about 1 minute (15
minutes at low temperature)
after the switch is turned on.
Inject to specified air pressure.
• 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 specified
tire inflation pressure is
reached.
• If the tire inflation pressure is still lower than the specified
point after inflation for 10
minutes (40 minutes at low
temperature) with the switch
on, the tire is too damaged to
be repaired. Turn the com-
pressor switch off and con-
tact your Scion dealer.
• If the tire inflation pressure exceeds the specified air
pressure, let out some air to
adjust the tire inflation pres-
sure. ( P. 301, 327)

298 5-2. Steps to take in an emergency
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 luggage room while it is
connected to the compressor.
To spread the liquid sealant evenl y 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.

■Emergency tire puncture repair kit
●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 replaced, contact your Scion dealer.
●The sealant can be used when the outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●The repair kit is exclusively designed for size and type of tires origi-
nally installed on your vehicle. Do not use it for tires that a different
size than the original ones, or for any other purposes.
●The sealant has a limited lifespan. The expiration date is shown on
the bottle. The sealant should be re placed before the expiration date.
Contact your Scion dealer.
●If the sealant gets on your 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 check or to adjust the tire pressure.

■If the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valve, 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 specified air pressure.
If the air pressure is under the designated pressure, turn the
compressor switch on again and repeat the inflation procedure
until the specified air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the tire
pressure warning valve and transmitter should be replaced.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiration date occasionally.
The expiry date is shown on the bottle.
Install the air release cap to the end of
the hose and push the protrusion on
the air release cap into the tire valve to
let some air out.

CAUTION
■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 room.
Otherwise, the repair kit may fly out and break in events such as sud-
den braking, and may cause an accident.
●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 completely
repaired, it could lead 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
doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the ar ea 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 in burns.
●Connect the valve and hose securely with the tire installed on the vehi-
cle. If the hose is not properly con nected to the valve, air leakage may
occur as sealant may be sprayed out.

CAUTION
■When fixing the flat tire
●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 comp leted, the sealant may splatter when
the hose is disconnected or so me air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures 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 ope ration is being performed. If 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 time. Do not
operate the repair kit continuously for more than 60 minutes.
●Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the metal part
connecting the bottle and the co mpressor. 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 may prevent
the SRS airbag from operating properly.
■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 cause death or
serious injury.
●Drive the vehicle carefully at a lo w speed. Be especially careful when
turning and cornering.
●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 the tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely damaged.

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 object may
widen the opening and disenable emergency 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 sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction
may occur.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle
use. Do not connect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate.
Take care not to allow gasoline 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 room out of reach of children.
●Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmit-
ters
When a tire is repaired with liquid se alants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Scion dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 223)
