When trouble arises
Attach the 2 stickers as shown.
Remove any dirt and moisture
from the wheel before attaching
the sticker.
Check the specified tire inflation
pressure.
Tire inflation pressure is specified
on the label as shown. (→P. 421)
Start the fuel cell system. ( →P. 172)
To inject the sealant and inflate
the tire, turn the compressor
switch on.

Inflate the tire until the specifiedair 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 infla-
tion pressure about 1 minute
(15 minutes at low tempera-
ture) after the switch is
turned on.
Inject to specified air pres-
sure.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the infla-
tion procedure until the
specified tire inflation pres-
sure is reached.
• If the tire inflation pr essure 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
compressor switch off and contact your Toyota dealer.
• If the tire inflation pressure exceeds the specified air pressure, let out some air to adjust the tire inflation pressure. ( →P. 421)

When trouble arises
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
compressor.
To spread the liquid sealant evenly 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 sur-
face and remove the air release
cap from the hose before
reconnecting the repair kit.

Turn the compressor switch on
and wait for several seconds,
and then turn it off. Check the
tire inflation pressure.If the tire inflation pressure is
under 19 psi (130 kPa,
1.3 kgf/cm
2 or bar): The
puncture cannot be repaired.
Contact your Toyota dealer.
If the tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm
2 or bar)
or higher, but less than the specified air pressure: Proceed to
step .
If the tire inflation pressure is the specified air pressure: Proceed
to step .
Turn the compressor switch on to in flate the tire until the specified
air 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 su dden braking, sudden acceleration
and sharp turns, drive carefully at under 50 mph (80 km/h) to the
nearest Toyota dealer tire repair or replacement.

When trouble arises
■In the following cases, the tire cannot be repaired with the emer-
gency tire puncture repair kit. Contact your Toyota dealer.
●When the tire is damaged due to driving without sufficient air pressure
●When there are any cracks or damage at any location on the tire, such
as on the side wall, except the tread
●When the tire is visibly separated from the wheel
●When the cut or damage to the tread is 0.16 in. (4 mm) long or more
●When the wheel is damaged
●When two or more tires have been punctured
●When more than two sharp objects su ch as nails or screws have passed
through the tread on a single tire
●When the sealant has expired
■Emergency tire puncture repair kit
●The sealant stored in the emergency ti re 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, purchase a new bottle at your Toyota 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 repair kit is exclusively designed for size and type of tires originally
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 expiry date is shown on the bot-
tle. The sealant should be replaced before the expiry date. Purchase a
new bottle at your Toyota dealer for replacement.
●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. Immediately 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 se conds, then turn
it off. Check that the air pressure indicator shows the specified air pres-
sure. ( →P. 421)
If the air pressure is under the designated pressure, turn the compres-
sor switch on again and repeat the inflation procedure until the speci-
fied air pressure is reached.
■After a tire is repaired with the emergency tire puncture repair 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 expiry date is shown on the bottle. Do not use sealant whose expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly.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.
WARNING
■
Caution while driving
●Store the repair kit in the trunk.
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 accide nt causing death or serious injury.
