5-2. Steps to take in an emergency
■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 running at a
low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is discharged
●The hybrid system may not start. (P. 4 3 4 )
●If the 12-volt battery is depleted with the shift position in P, it will not be possible
to shift out of P. In this case, the vehi cle cannot be towed without lifting both
front wheels because the front wheels are locked by the parking lock. 
(  P. 4 8 3 )
●When the 12-volt battery is reconnected, start the hybrid system, depress the
brake pedal, and confirm that it is poss ible to shift into each shift position.
Close the exclusive jump starting terminal cover and reinstall
the fuse box cover.
Once the hybrid system starts, have the vehicle inspected at your
