■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 dis-charge
●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
●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.
●Some systems may require initializa-
tion. ( P.609)
■When removing the 12-volt battery terminals
When the 12-volt battery terminals are
removed, the information stored in the ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■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 hybrid system may be unable to start. (The 12-volt battery recharges automatically
while the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●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 hybrid system may not start on the first attempt after reinstalling the
12-volt battery. In that case, start the hybrid system in the same manner as when the electronic key does not

5768-2. Steps to take in an emergency
operate properly ( P.572). This is not
a malfunction, as the hybrid system will start normally on the second attempt.
●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.
■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 (LN2), 20 hours rate capacity (20HR) is equivalent (55Ah) or greater, and
performance rating (CCA) is equiva- lent (345A) or greater.• If the sizes differ, the 12-volt battery
cannot be properly secured. • 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 hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●When removing the 12-volt battery:  P.486
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery. • Use the exhaust hose that was attached to the 12-volt battery before
replacing and confirm that it is firmly connected to the hole section of the vehicle.
• Use the exhaust hole plug included with the new 12-volt battery or the one installed on the battery prior to the
replacement. (Depending on the new
12-volt battery installed, the exhaust hole may be plugged.)
For details, consult any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
■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:
