If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the
situation. Check the following and perform the appropriate proce-
dure:
■The hybrid system will not start even though the correct
starting procedure is being followed (→P. 2 4 0 )
One of the following may be the cause of the problem:
●The charging cable may be attached to the vehicle. (→P. 9 5 )
●The electronic key may not be functioning properly.*
(→P. 5 9 4 )
●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. 1 8 3 )
●There may be a malfunction in the P position control system.*
(→P. 2 4 5 , 5 5 0 )
*:It may not be possible to shift the shift position from P to other posi-
tion.
■The interior lights and headlights 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. 5 9 7 )
●The 12-volt battery terminal connections 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 p r e v e n t 1 2 - v o l t b a t t e r y d i s c h a r g e
●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. 4 7 6 )
●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. 5 2 7 )
●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. 4 7 8
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.
