MessageDetailsCorrection procedure
Charging has been inter-
rupted because the plug
has been disconnected
or some kind of power
failure has occurred. Charging has not fin-
ished properly.
Refer to the procedures
on P. 84 and perform
charging again.
The vehicle can be used
even if charging has not
finished. However, the
distance that can be
driven in EV mode
decreases.
One of the following situ-
ations has occurred:
• The charging connector is not properly inserted
• The latch release button has been pressed and
held
• The charging connector has been disconnected Reinsert the charging
connector to restart
charging.
Charging has been inter-
rupted by a malfunction
in the charging system. Stop charging immedi-
ately, and contact your
Toyota dealer.
Also, driving is possible
when the hybrid system
has been started.

procedure
Charging has been
stopped because of the
high energy consumption
of electrical compo-
nents, such as the head-
lights. Switch the electrical
appliance OFF, and
restart charging by fol-
lowing the procedure on
P. 84.
If the message is still
displayed, the 12-volt
battery may have a low
charge.
In this event, turn the
“POWER” switch OFF
approximately 15 min-
utes after starting the
hybrid system, and
restart charging.
Charging has been
stopped because of
extremely low voltage,
possibly caused by the
plug not being inserted
correctly. Check that the plug is
inserted correctly, and
restart charging by fol-
lowing the procedure on
P. 84.
Check that the plug is
not connected to a
power strip and that an
extension cord, multi-
outlet etc. is not being
used.

MessageDetailsCorrection procedure
Charging has been
stopped because of a
problem with the charg-
ing cable. If the charging cable is
not a genuine Toyota
product, or if you are
charging using a charg-
ing station (other than a
Toyota dealer), try charg-
ing with a genuine Toyota
charging cable.
If the message is still
displayed, contact your
Toyota dealer.
Charging has stopped
because of the continued
high temperature of the
hybrid battery (traction
battery) (in order to pro-
tect the battery). If the desired charge
level has not been
achieved, restart charg-
ing by following the pro-
cedure on P. 84 after the
hybrid battery (traction
battery) has cooled
down.

If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the
situation. Check the following a nd perform the appropriate proce-
dure:
■ The hybrid system will not start even though the correct
starting procedure is being followed ( P. 240)
One of the following may be the cause of the problem:
● The charging cable may be attached to the vehicle. ( P. 95)
● The electronic key may not be functioning properly.
*
( P. 594)
● There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( P. 4 6 )
● There may be a malfunction in the immobilizer system.
*
( P. 183)
● There may be a malfunction in the P position control system.
*
( P. 245, 550)
*: It may not be possible to shift the shift position from P to other posi-
tion.
■ The interior lights and headlight s are dim, or the horn does
not sound or sounds at a low volume
One of the following may be the cause of the problem:
● The 12-volt battery may be discharged. ( P. 597)
● The 12-volt battery terminal c onnections may be loose or cor-
roded.

■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( P. 476)
● If the 12-volt battery is depleted with the shift position in P, it will not be
possible to shift the shift position other than P. In this case, the vehicle
cannot be towed without lifting both front wheels because the front
wheels are locked by the parking lock. ( P. 527)
● When the 12-volt battery is reconnected, start the hybrid system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
■ 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 draining
effects of certain electrical appliances. If the vehicle is left for a long time, the
12-volt battery may discharge, and the hybrid system may be unable to start.
(The 12-volt battery charges automatically while the hybrid system is operat-
ing.)

CAUTION
■After charging the 12-volt battery
Have the 12-volt battery inspected at your Toyota dealer as soon as possi-
ble.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt
battery to emit a malodorous gas, which may be detrimental to the health of
passengers.
■ When replacing the 12-volt battery
P. 478
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans, etc.
■ Exclusive jump starting terminal
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump start
another vehicle.
