When trouble arises
QIf the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the
hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then turn
it off. Check that the air pressure indicator shows the specifi ed air pressure.
( P. 721)
If the air pressure is under the designated pressure, turn the compressor
switch on again and repeat the inflation procedure until the sp ecified air
pressure is reached.
Q The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repai r kit, the valve
should be replaced.
Q After a tire is repaired with the emergency tire puncture repair kit (vehi-
cles with the tire pressure warning system)
O The tire pressure warning valve and transmitter should be replaced.
O Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
Q Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whos e expiry date
has already passed. Otherwise, repairs conducted using the emer gency tire
puncture repair kit may not be performed properly.
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.

When trouble arises
If the hybrid system will not star t
One of the following may be the cause of the problem:
O The charging cable may be attached to the vehicle. (P. 155)
O The electronic key may not be functioning properly.* (P. 693)
O There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( P. 100)
O There may be a malfunction in the immobilizer system.* (P. 7 4 )
O There may be a malfunction in the shift control system.*
( P. 326, 672)
O The hybrid system may be malfunctioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. H ow-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. ( P. 692)
O There is a possibility that the temperature of the hybrid battery
(traction battery) is extremely low (approximately below -30 C
[-22 F]). (P. 100, 325)
*: It may not be possible to shift the shift position other than P.
One of the following may be the cause of the problem:
O The 12-volt battery may be discharged. (P. 697)
O The 12-volt battery terminal connections may be loose or corroded.
( P. 594)
Reasons for the hybrid system not starting vary depending on
the situation. Check the following and perform the appropriate
procedure:
The hybrid system will not start even though the correct starti ng
procedure is being followed. ( P. 323)
The interior lights and headlights are dim, or the horn does not
sound or sounds at a low volume.

6928-2. Steps to take in an emergency
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
One of the following may be the cause of the problem:
O The 12-volt battery may be discharged. (P. 697)
O One or both of the 12-volt battery terminals may be disconnected.
( P. 594)
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer if the problem cannot be repaired, or if repa ir procedures
are unknown.
When the hybrid system does not start, the following steps can be
used as an interim measure to start the hybrid system if the po wer
switch is functioning normally.
Do not use this starting procedure except in cases of emergency .
Set the parking brake.
Turn the power switch to ACCESSORY mode.
Press and hold the power switch for about 15 seconds while
depressing the brake pedal firmly.
Even if the hybrid system can be started using the above steps, the
system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
The interior lights and headlights do not turn on, or the horn
does not sound.

Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) batte ry
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery term i-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the 12-vo lt
battery and any moving parts, as shown in the illustration.
Start the engine of the second vehicle. Increase the engine spe ed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the power switch to ON
mode.
Make sure the “READY” indicator comes on. If the indicator ligh t
does not come on, contact any authorized Toyota retailer or Toy ota
authorized repairer, or any reliable repairer.

When trouble arises
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
reverse. After installing, check that the fixed pins are insert ed
securely.
Once the hybrid system starts, have the vehicle inspected at an y
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer as soon as possible.
Q When opening the cover of the positive (+) battery terminal
 P. 595
Q Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Q To prevent 12-volt battery discharge
O Turn off the headlights and the audio system while the hybrid system is off.
O Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
Q When the 12-volt battery is removed or discharged
O Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota r etailer or
Toyota authorized repairer, or any reliable repairer.
O Some systems may require initialization. (P. 734)
Q When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
Q Charging the 12-volt battery
The electricity stored in the 12- volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the dra ining effects of
certain electrical appliances. If the vehicle is left for a lon g time, the 12-volt
battery may discharge, and the hybrid system may be unable to s tart. (The
12-volt battery recharges automat ically while the hybrid system is operating.)

When trouble arises
WARNING
QWhen removing the 12-volt battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) t erminal is
removed, a spark may occur, leading to a fire in addition to el ectrical shocks
and death or serious injury.
Q Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally ignit ing the flam-
mable gas that may be emitted from the 12-volt battery:
O Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the in tended terminal.
O Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
O Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
O Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.
Q 12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic ele ctrolyte,
while related parts contain lead and lead compounds. Observe th e following
precautions when handling the 12-volt battery:
O When working with the 12-volt battery, always wear safety glasses and
take care not to allow any battery fluids (acid) to come into c ontact with
skin, clothing or the vehicle body.
O Do not lean over the 12-volt battery.
O 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 medica l attention
can be received.
O Always wash your hands after handling the 12-volt battery support, termi-
nals, and other battery-related parts.
O Do not allow children near the 12-volt battery.
