5748-2. 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.546)
 For vehicles with power back
door: Turn off the power back
door system. ( P.195)
 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.
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 seal-
ant can be used only once
to temporarily 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 emergency tire
puncture repair kit.
( P.575)
After temporarily repairing
the tire with the kit, have the
tire repaired or replaced 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 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.
Before repairing the vehi-
cle

5828-2. Steps to take in an emergency
dealer.
When having the tire repaired or
replaced, make sure to tell your
Toyota dealer 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 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 under the des-
ignated 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.
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.
●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.

When trouble arises
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. (P.585)
 There is a possibility that the
temperature of the hybrid bat-
tery (traction battery) is
extremely low (approximately
below -22°F [-30°C]). ( P.84,
252)
*: It may not be possible to shift the shift position from P.
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.589)
 The 12-volt battery terminal
connections may be loose or
corroded. ( P.512)
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.589)
 One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.512) Contact your Toyota dealer if
the problem cannot be repaired,
or if repair procedures are
unknown.
When the hybrid system does
not start, the following steps can
