■Starting the EV system when the 12-volt battery is discharged
The EV system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the navigation system while the EV 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 EV system may not start. (P. 363)
● If the 12-volt battery discharges while the shift position is in P, it may not
be possible to shift the shift position to other positions.
In this case, the vehicle cannot be moved without lifting both front wheels
because the front wheels will be locked. ( P. 413)
● The power windows must be initialized. ( P. 147)
■ 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 EV system may be unable to start.
(The 12-volt battery recharges automatically while the EV system is operat-
ing.)
