If you have a flat tire
(vehicles without
spare 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 tem-
porarily using the emer-
gency tire puncture repair
kit. (The kit contains a bottle
of sealant. The sealant can
be used only once to tempo-
rarily repair one tire without
removing the nail or screw
from the tire.) Depending on
the damage condition of the
flat tire, it may not be able to
repaired with the emer-
gency tire puncture repair
kit. ( P.482)
After temporarily repairing
the tire with the kit, have the
tire repaired or replaced by
your Toyota dealer.

4827-2. Steps to take in an emergency
Stop the vehicle in a safe
place on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
 Stop the hybrid system.
 Turn on the emergency flash-
ers. ( P.458)
 Disable the power sliding door
system. ( P.148)
 For vehicles with power back
door: Disable the power back
door system. ( P.163)
 Check the degree of the tire
damage.
A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.
• Do not remove the nail or screw from the tire. Removing
the object may widen the opening and prevent emer-
gency repair with the repair
kit.
• To avoid sealant leakage, move the vehicle until the
area of the puncture, if
known, is positioned at the
top of the tire.
■Jack and tools
As your vehicle is equipped with the
emergency tire puncture repair kit,
the following tools for replacing a
tire are not include d with your vehi-
cle. They can be purchased at your
Toyota dealer.
●Wheel nut wrench
●Jack
●Jack handle
■A flat tire that cannot be
repaired with the emergency

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 and
the wheel beyond repair, which
could result in an accident.
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.

●The sealant can be used when the
outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●The kit is exclusively designed for
size and type of tires originally
installed on your vehicle. Do not
use it for tires t hat different size
than the original ones, or for any
other purposes.
●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 pro-
duced. This does not indicate a
malfunction.
●Do not use to check or to adjust
the tire pressure.
1 Remove the cover.

When trouble arises
13Inflate 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 rec-
ommended tire inflation pressure
is reached.
• If the tire inflation pressure is still lower than the recommended level after inflatio
n for 25 minutes
with the switch on, 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 recommended level,
let out some air to adjust the tire
inflation pressure. ( P.488, 525)
14With 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.
15Install the valve cap onto the valve of the emergency
repaired tire.
16Attach 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.
17Temporarily store the bottle in the trunk while it is con-
nected to the compressor.
18To spread the liquid sealant evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).

19After driving, stop your vehi-
cle in a safe place on a hard,
flat surface and reconnect
the compressor.
20 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
below 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
between 19 psi (130 kPa, 1.3
kgf/cm
2 or bar) and a point
below the recommended
level: Proceed to step 21 .
If the tire inflation pressure is
at the recommended level:
Proceed to step 22. 21Turn the compressor switch
on to inflate the tire until the
recommended tire inflation
pressure is reached. Drive for
about 3 miles (5 km) and
then perform step 19 .
22Attach 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.
23Store the bottle in the lug-gage compartment while it is
connected to the compres-
sor.
24Taking precautions to avoid sudden braking, sudden
acceleration and sharp turns,
drive carefully at under
50mph (80 km/h) to your
Toyota dealer that is less
than 62 miles (100 km) away
for tire repair or replacement.
Make sure to tell your Toyota
dealer when you have them repair
or replace the tire that sealant is
injected.

When trouble arises
2Install 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.
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 several seconds,
and then turn it off. Check that
the air pressure indicator shows
the specified air pressure.
If the air pressure is lower than the
designated pressure, turn the com-
pressor 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
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 whee ls 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 vehicle. If the hose is not
properly connected to the valve,
air leakage may occur as seal-
ant 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-
dures 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 repair
kit continuously for more than
40 minutes.
