The hybrid battery (traction bat-
tery) is scheduled to be inspected
or replaced. Have the vehicle
inspected by your Toyota dealer

●If the hybrid system does not

dealer immediately.

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.

5928-2. Steps to take in an emergency
of the 12-volt battery.
• Use the exhaust hose that was attached to the 12-volt battery
before replacing and confirm that
it is firmly connected to the hole
section of the vehicle.
• Use the exhaust hole plug included with the 12-volt battery
replaced or the one installed on
the battery prior to the replaced.
(Depending on the 12-volt battery
to be replace, the exhaust hole
may be plugged.)
For details, consult your Toyota
dealer.

WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, le ading to a fire
in addition to electrical shocks
and death or serious injury.

■Avoiding 12-volt battery fires
or explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the 12-volt battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poi-
sonous and corrosive acidic elec-
trolyte, while related parts contain
lead and lead compounds.
Observe the following precautions
when handling the 12-volt battery:
●When working with the 12-volt
battery, always wear safety
glasses and take care not to
allow any battery fluids (acid) to
come into cont act with skin,
clothing or the vehicle body.
●Do not lean over the 12-volt bat-
tery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention.
Place a wet sponge or cloth
over the affected area until
medical attention can be
received.
