Emergency start function
When the hybrid system does not start, the following steps can be
used as an interim measure to start the hybrid system if the
“POWER” switch is functioning normally:
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 your
To y o t a d e a l e r .
■The interior lights and headlights do not turn on, or the horn
does not sound
One of the following may be the cause of the problem:
●One or both of the 12-volt battery terminals may be discon-
nected.
●The 12-volt battery may be discharged. (→P. 5 9 4 )
Contact your Toyota dealer if the problem cannot be repaired, or if
repair procedures are unknown.

■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 3 )
●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 5 )
●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.)
