5-2. Steps to take in an emergency
PRIUS PHV_OM_OM47856U_(U)
■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.)
