■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 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. 362)
Start the engine of the second vehicle. Increase the gaso-
line engine speed slightly and maintain at that level for
approximately 5 minutes to recharge the 12-volt battery of
your vehicle.
Open and close any of the doors with the “POWER” switch
OFF.
Maintain the engine speed of the second vehicle and turn
the “POWER” switch to ON mode, then start the hybrid sys-
tem.
Make sure the “READY” indicator comes on. If the indicator
does not come on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Once the hybrid system starts, have the vehicle checked at your
Toyota dealer as soon as possible.STEP3

■
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 recharges automatically while the hybrid system is oper-
ating.)
■ Precautions when the 12-volt battery is discharged
●In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote con-
trol or the mechanical key to lock or unlock the doors.
● The hybrid system may not start on the first attempt after the 12-volt bat-
tery has recharged but will start normally after the second attempt. This is
not a malfunction.
● The “POWER” switch mode is memorized by the vehicle. When the 12-
volt battery is reconnected, the system will return to the mode it was in
before the 12-volt battery was discharged. Before disconnecting the 12-
volt battery, turn the “POWER” switch off.
If you are unsure what mode the “POWER” switch was in before the 12-
volt battery discharged, be especially careful when reconnecting the 12-
volt battery.
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 + 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.

CAUTION
■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.
■ After recharging 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.
