■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.)

CAUTION
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the following
precautions when handling the 12-volt battery:
●When working with the 12-volt battery, always wear safety glasses and
take care not to allow any battery fluids (acid) to come into contact with
skin, clothing or the vehicle body.
●Do not lean over the 12-volt battery.
●In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
●Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
●Do not allow children near the 12-volt battery.

CAUTION
■After charging the 12-volt battery
Have the 12-volt battery inspected at your Toyota dealer as soon as possi-
ble.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt
battery to emit a malodorous gas, which may be detrimental to the health of
passengers.
■When replacing the 12-volt battery
→P. 4 7 5
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans, etc.
■Exclusive jump starting terminal
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump start
another vehicle.
