If you have a flat tire
Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail o r screw from the tire.)
After temporarily repairing the tire with the repair kit, have the
tire repaired or replace d by your Toyota dealer.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving, even a short distance, with a flat tire can damage the tire, the
wheel, and other parts beyond rep air, which could result in an accident.

When trouble arises
●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift position to P.
● Stop the fuel cell system.
● Turn on the emergency flashers. ( P. 408)
● Check the degree of the tire damage.
A tire should only be repaired with
the emergency tire puncture
repair kit if the damage is caused
by a nail or screw passing through
the tire tread. • Do not remove the nail or screw from the tire. Removing the
object may widen the opening
and disenable emergency
repair with the repair kit.
• To avoid sealant leakage, move t he vehicle until the area of the
puncture, if known, is positioned at the top of the tire.
■A flat tire that cannot be repaired with the emergency tire pun cture
repair kit
In the following cases, the tire cannot be repaired with the em ergency 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 tr ead 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 such as nails or screws have p assed
through the tread on a single tire
●When the sealant has expired

When trouble arises
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 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
compressor switch off and c ontact your Toyota dealer.
• If the tire inflation pressure exceeds the specified air press ure, let
out some air to adjust the tire inflation pressure. ( P. 471)

With the compressor switch off, disconnect the hose from the valve
on the tire and then pull out the power plug from the power out let
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 t he trunk while it is connected to the
compressor.
To spread the liquid sealant evenly within the tire, immediatel y 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.
