Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Avoiding a discharged 12-volt battery
Turn off the headlights and the audio system while the hybrid system is
turned 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, etc.
When the 12-volt battery is removed or discharged
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 vehicle cannot be towed without
lifting both front wheels because the front wheels are locked by the park-
ing lock. (P. 423)
The hybrid system may not start. (P. 384)
Once the hybrid system has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Close the exclusive jump starting terminal cover and rein-
stall the fuse box cover.
Once the hybrid system starts, have the vehicle checked at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, as soon as possible.STEP7
