8-2. Steps to take in an emergency
When trouble arises
13To inject the sealant and inflate
the tire, turn the compressor
switch on.
14 Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and
the pressure will spike to
between 300 kPa (3.0 kgf/cm2
or bar, 44 psi) and 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 to 5 minutes 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 proce-
dure until the specified tire inflation
pressure is reached.
• The tire can be inflated for about 5 to
20 minutes (depending on the out-
side temperature). If the tire inflation
pressure is still lower than the speci-
fied point after inflation for 25 min-
utes, the tire is too damaged to be
repaired. Turn the compressor switch
off and contact any authorized Toyota
retailer or Toyota authorized repairer,
or any reliable repairer.
• If the tire inflation pressure exceeds
the specified air pressure, let out
some air to adjust the tire inflation
pressure. ( P.537)
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.
16 Install the valve cap onto the
valve of the emergency repaired
tire.
17 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.
18 Temporarily store the bottle in
the luggage compartment while
it is connected to the compres-
sor.
19 To spread the liquid sealant
evenly within the tire, immedi-
ately drive safely for about 5 km
(3 miles) below 80 km/h (50
mph).
20 After driving, stop your vehicle in
a safe place on a hard, flat sur-
face 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 seconds,
then turn it off. Check the tire
inflation pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm2 or
bar, 19 psi): The puncture can-
not be repaired. Contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
If the tire inflation pressure is
130 kPa (1.3 kgf/cm2 or bar, 19
psi) or higher, but less than the
specified air pressure: Proceed
to step 22.
If the tire inflation pressure is the
specified air pressure ( P.559):
Proceed to step 23.
22 Turn the compressor switch on
to inflate the tire until the speci-
fied air pressure is reached.
Drive for about 5 km (3 miles)
and then perform step 20.
23 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

8-2. Steps to take in an emergency
When trouble arises
may get dirty.
24Store the bottle in the luggage
compartment while it is con-
nected to the compressor.
25 Taking precautions to avoid sud-
den braking, sudden accelera-
tion and sharp turns, drive
carefully at under 80 km/h (50
mph) to the nearest authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer that is less than 100 km
(62 miles) away for tire repair or
replacement.
For repair and replacement of a tire or disposal of the tire puncture repair kit, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
When having the tire repaired or
replaced, make sure to tell any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer
that the sealant is injected.
■If the tire is inflated 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 reconnect the hose.
4 Turn the compressor switch on and wait for several seconds, then turn it
off. Check that the air pressure indi- cator shows the specified air pres-sure is reached. ( P.559)
If the air pressure is under the desig- nated pressure, turn the compres-sor switch on again and repeat the
inflation procedure until the specified 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 pres-
sure 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 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.

8-2. Steps to take in an emergency
WARNING
●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 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 com-
pleted, 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 opera-
tion 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 oper-ated for a long period of time. Do not operate the compressor contin-
uously for more than 40 minutes.
●Parts of the repair kit become hot
during operation. Be careful han- dling 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 oper- ating properly.
■Driving to spread the liquid seal-ant 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 steer- ing 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 130 kPa (1.3
kgf/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■When performing an emergency repair
●Perform the emergency repair with-
out removing the nail or screw that has punctured the tread of the tire. If the object that has punctured 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.
●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 malfunc- tion may occur.
●Make sure the sealant bottle of the repair kit is in a vertical position. The repair kit does not operate
properly when it is laid.
