When trouble arises
12 Start the EV system.
( P.231)
13 To inject the sealant and
inflate the tire, turn the com-
pressor switch on.
14 Inflate the tire until the rec-
ommended pressure is
reached.
The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa, 3.0
kgf/cm
2 or bar) and 58 psi
(400 kPa, 4.0 kgf/cm
2 or bar), then gradually decrease.
The air pressure gauge will
display the actual tire inflation
pressure about 1 to 5 min-
utes 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 speci-
fied tire inflation pressure is
reached.
• The tire can be in flated for about
5 to 20 minutes (depending on
the outside temperature). If the
tire inflation press ure is still lower
than the specified point after infla-
tion for 25 minutes, the tire is too
damaged to be repaired. Turn the
compressor switch off and con-
tact your Toyota dealer.
• If the tire inflation pressure exceeds the spec ified air pres-
sure, let out some air to adjust the
tire inflation pressure. ( P.535)
15With the compressor switch
off, pull out the power plug
from the power outlet socket
and then disconnect the hose
from the valve on the tire.
Some sealant may leak when the
hose is removed.
16Install the valve cap onto the valve of the emergency
repaired tire.
17Attach the air release cap to the end of the hose.
If the air release cap is not
attached, the sealant may leak and

18Temporarily store the bottle
in the luggage compartment
while it is connected to the
compressor.
19 To spread the liquid sealant
evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).
20 After driving, stop your vehi-
cle in a safe place on a hard,
flat surface and reconnect
the repair kit.
Remove the air release cap from
the hose before reconnecting the
hose.
21 Turn the compressor switch
on and wait for several sec- onds, 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 pres-
sure: Proceed to step 22.
If the tire inflation pressure is
the specified air pressure
( P.555): Proceed to
step 23.
22Turn the compressor switch on to inflate the tire until the
specified air pressure is
reached. Drive for about 3
miles (5 km) and then per-
form step 20.
23Attach the air release cap to the end of the hose.
If the air release cap is not
attached, the sealant may leak and

24Store the bottle in the lug-
gage compartment while it is
connected to the compres-
sor.
25 Taking precautions to avoid
sudden braking, sudden
acceleration and sharp turns,
drive carefully at under 50
mph (80 km/h) to the nearest
Toyota dealer that is less
than 62 miles (100 km) away
for tire repair or replacement.
For repair and replacement of a tire
or disposal of the tire puncture
repair kit, contact your Toyota
dealer.
When having the tire repaired or
replaced, make sure to tell the Toy-
ota dealer that the sealant is
injected.
■If the tire is i nflated to more
than the specified air pressure
1 Disconnect the hose from the
valve.
2 Install the air release cap to the
end of the hose and push the
protrusion on the air release cap
into the valve to let some air out. 3
Disconnect the hose from the
valve, remove the air release cap
from the hose and then recon-
nect the hose.
4 Turn the compressor switch on
and wait for seve ral seconds,
then turn it off. Check that the air
pressure indicator shows the
specified air pressure is reached.
(  P.555)
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.
■After a tire is re paired 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.
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 immedi-
ately 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.

WARNING
●Connect the valve and hose
securely with the tire installed
on the vehicle.
If the hose is not properly con-
nected to the valve, air leakage
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
splatter when the hose is dis-
connected or some air is let out
of the tire.
●Follow the operation procedure
to repair the tire. If the proce-
dure 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 per-
formed. If you notice any cracks
or deformation of the tire, turn
off the compressor switch and
stop the repair operation imme-
diately.
●The repair kit may overheat if
operated for a long period of
time. Do not operate the com-
pressor continuously 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 metal 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 may prevent the SRS
air bag 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
low 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 fol-
lowing:
• 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 dam-
aged.
NOTICE
■When performing an emer-
gency repair
●Perform the emergency repair
without removing the nail or
screw that has punctured the
tread of the tire. If the object
that has punctur ed the tire is
removed, repair by the emer-
gency tire puncture repair kit
may not be possible.
●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.
