When trouble arises
order from which they were con-
nected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts, have
the vehicle inspected at any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■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 dis-charge
●Turn off the headlights, the air condi-tioning system, the audio system, etc.
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.
■Charging the 12-volt battery
The electricity stored in the 12-volt bat- tery 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 vehi-cle is left for a long time, the 12-volt bat-
tery may discharge, and the EV system may be unable to start. (The 12-volt bat-tery recharges automatically while the
EV system is operating.)
■When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is depleted, have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer.
●In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the 12-volt
battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
●The EV system may not start on the first attempt after the 12-volt battery 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 bat-tery is reconnected, the system will
return to the mode it was in before the 12-volt battery was discharged. Before disconnecting the 12-volt bat-
tery, 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.
●If the 12-volt battery discharges, it may not be possible to shift the shift
position to other positions. In this case, the vehicle cannot be towed without lifting both front wheels
because the front wheels will be locked.
●The power back door (if equipped) must be initialized. ( P.198)
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
●Use a 12-volt battery that the case size is same as the previous one (LN1), 20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and per- formance rating (CCA) is equivalent (286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.• If an improper 12-volt battery is used,
battery performance may decrease and the EV system may not be able to restart.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the 12-
volt battery may discharge and EV system may not be able to start.

For details, consult with at any autho-
rized Toyota retailer or Toyota autho- rized repairer, or any reliable repairer as soon as possible.
WARNING
■When removing the 12-volt bat-tery terminals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.
■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 “+”
terminal 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 con- tact with each other.
●Do not smoke, use matches, ciga-rette lighters or allow open flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poison- ous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the follow-ing precautions when handling the
12-volt battery:
●When working with the 12-volt bat- tery, always wear safety glasses
and take care not to allow any bat- tery fluids (acid) to come into con-tact with skin, clothing or the vehicle
body.
●Do not lean over the 12-volt battery.
●In the event that battery fluid (acid) 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 han-dling the 12-volt battery and other
battery-related parts.
●Do not allow children near the 12-
volt battery.
■When replacing the 12-volt bat-
tery
●When the vent plug is close to the hold down clamp, the battery fluid
(acid) may leak.
●For information regarding battery
replacement, contact any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
