■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.440)
■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 (vehicles with a smart entry & start system)
●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 the 12-volt bat- tery has recharged but will start nor-mally 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
p owe r swi t ch wa s i n be f or e t he 1 2- v ol t battery discharged, be especially careful when reconnecting the 12-volt
battery.
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt
battery (European Regulations).
●Use a battery that the case size is
same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating
(CCA) is equivalent or greater. Check the label on top of the battery for the battery size and specifications (ex.
LN0, 35Ah, 264A). • 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 the 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. 3 3 0
●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 12-volt battery replaced or the one installed on the 12-volt battery
prior to the replacement. (Depending
on the 12-volt battery to be replaced, the exhaust hole may be plugged.)

WARNING
●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 comes into contact with the skin or eyes, immediately wash the affected area
with water and seek medical atten- tion. Place a wet sponge or cloth over the affected area until medical
attention can be received.

dling the 12-volt battery support, terminals, and other battery-related parts.
●Do not allow children near the 12-volt battery.
■After recharging the 12-volt bat-tery
Have the 12-volt battery inspected at
any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer as soon as possible.
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 bat-tery
●For information regarding 12-volt
battery replacement, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
●After replacing, securely attach the
exhaust hose and exhaust hole plug to the exhaust hole of the replaced 12-volt battery. If not prop-
erly installed, gases (hydrogen) may leak into the vehicle interior, and there is the possible danger of
the gas igniting and exploding.
