■Starting the hybrid system when
the 12-volt battery is discharged
The hybrid system c annot 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 r equire initializa- tion. ( →P.643)
■When removing the 12-volt battery
terminals
When the 12-volt batte ry terminals are removed, the in formation stored in the
ECU is cleared. Before removing the 12-
volt battery termi nals, contact any authorized Toyota r etailer or Toyota
authorized repairer, or any reliable
repairer.
■Charging the 12-volt battery
The electricity stor ed in the 12-volt bat-
tery will discharge gr adually even when
the vehicle is not in use, due to natural discharge and the dr aining 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 t o start. (The 12-
volt battery recharges automatically while the hybrid syst em 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 o r 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 t hat case, start the hybrid system in t he same manner as
when the electr onic key does not
operate properly ( →P.605). 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 batt ery 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.508
●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 conne cted 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 part s 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.

●If steam is seen coming from under
the hood, do not open the hood until the steam has subsided. The
engine compartment may be very
hot.
●After the hybrid system has been
turned off, check that the “READY” indicator is off.
When the hybrid system is operat -
ing, the gasoline engine may auto - matically start, or the cooling fan
may suddenly operate even if the
gasoline engine stops. Do not touch or approach rotatin g parts such as
the fan, which may lead to fingers
or clothing (especia lly a tie, a scarf or a muffler) getting caught, result -
ing in serious injury.
●Do not loosen the c oolant reservoir
cap while t he hybrid system and
radiator are hot. High temperature steam or coolant
could spray out.
NOTICE
■When adding engine/power con -
trol unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently.
Adding cool coolant to a hot hybrid
system too quickly can cause dam- age to the hybrid system.
■To prevent damage to the cool -
ing system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust, etc.).
●Do not use any coolant additive.
