possible.
■Starting the hybrid system 
when the 12-volt battery is dis-
charged
The hybrid system cannot be 
started by push-starting.
■To prevent 12-vol t battery dis-
charge
●Turn off the headlights and the 
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary electri-
cal components when the vehicle 
is running at a low speed for an 
extended period, such as in heavy 
traffic.
■When the 12-volt battery is 
removed or discharged
●Information stor ed in the ECU is 
cleared. When the 12-volt battery 
is depleted, have the vehicle 
inspected at your Toyota dealer.
●Some systems may  require initial-
ization. ( P.718)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals 
are removed, the information stored 
in the ECU is cleared. Before 
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt 
battery will discharge gradually even 
when the vehicle is not in use, due 
to natural discharge and the drain-
ing effects of certa in electrical appli-
ances. If the vehicle is left for a long 
time, the 12-volt battery may dis-
charge, and the hybrid system may 
be unable to start. (The 12-volt bat-
tery recharges aut omatically while 
the hybrid system is operating.)
■When recharging or replacing 
the 12-volt battery (vehicles 
without smart key system)
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.
■When recharging or replacing 
the 12-volt battery (vehicles 
with smart key system)
●In some cases, it may not be pos-
sible to unlock the doors using the 
smart key system when the 12-
volt battery is discharged. Use the 
wireless remote c
ontrol or the 
mechanical key to lock or unlock 
the doors.
●The hybrid syste m may not start 
on the first attempt after the 12-
volt battery has  recharged but will 
start normally after the second 
attempt. This is n ot a malfunction.
●The power switch mode is memo-
rized 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 discon-
necting the 12-volt battery, turn 
the power switch to OFF.
If you are unsure what mode the 
power switch was in before the 
12-volt battery discharged, be 
especially careful when recon-
necting the 12-volt battery.
●Some systems may require initial-
ization. (P.718)
■When replacing t he 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Type A:
Use a battery that the case size is 
same as the previous one (LN1), 20 
hours rate capacity (20HR) is equiv-
alent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent 
(285A) or greater.
Type B:
Use a battery that the case size is 
same as the previous one (LN1), 20 
hours rate capacity (20HR) is equiv- 
Page 674 of 752

6748-2. Steps to take in an emergency
alent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent 
(286A) or greater.
Type C:
Use a battery that the case size is 
same as the previous one (LN2), 20 
hours rate capacity (20HR) is equiv-
alent (55Ah) or greater, and perfor-
mance rating (CCA) is equivalent 
(345A) or greater.
• If the sizes differ, the 12-volt bat-
tery cannot be pr operly secured.
• If the 20 hour rate  capacity is low, 
even if the time period where the 
vehicle 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 t ype calcium bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt b attery without a 
handle is used, removal is more 
difficult.
●When removing the 12-volt bat-
tery:  P.589
●After replacing, firmly attach the 
following items to the exhaust hole 
of the 12-volt battery.
• Use the exhaust hose that was  attached to the 12-volt battery 
before replacing an d confirm that 
it is firmly connected to the hole 
section of t he vehicle.
• Use the exhaust hole plug 
included with the  new 12-volt bat-
tery or the one installed on the 
battery prior to t he replacement. 
(Depending on the new 12-volt 
battery installed, the exhaust hole 
may be plugged.)

WARNING
■When removing the battery 
terminals
Always remove the negative (-) 
terminal first. If the positive (+) ter-
minal contacts any metal in the 
surrounding area when the posi-
tive (+) terminal is removed, a 
spark may occur, leading to a fire 
in addition to ele ctrical shocks 
and death or serious injury.
■Avoiding 12-volt  battery fires 
or explosions
Observe the following precautions 
to prevent accidentally igniting the 
flammable gas that may be emit-
ted from the 12-volt battery:
●Make sure each jumper cable is 
connected to the correct termi-
nal and that it is not unintention-
ally 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 contact with each other.

WARNING
●Do not smoke, use matches, 
cigarette lighters or allow open 
flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poi-
sonous and corrosi ve acidic elec-
trolyte, 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 bat-
tery.
●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 12-volt battery sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow child ren near the 
12-volt battery.
■After recharging the 12-volt 
battery
Have the 12-volt battery 
inspected at your Toyota dealer 
as soon as possible.
If the 12-volt battery is deteriorat-
ing, continued use may cause the 
12-volt battery to emit a malodor-
ous gas, which may be detrimen-
tal to the health of passengers.
■When replacing the 12-volt 
battery
●For information regarding 12-
volt battery rep lacement, con-
tact your Toyota dealer.
●After replacing, s ecurely attach 
the exhaust hose and exhaust 
hole plug to the exhaust hole of 
the replaced 12-volt battery. If 
not properly installed, gases 
(hydrogen) may leak into the 
vehicle interior,  and there is the 
possible danger of  the gas ignit-
ing and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper 
cables, ensure that they do not 
become entangled in the cooling 
fan, etc.
■To prevent damaging the 
vehicle
The exclusive jump starting termi-
nal is to be used  when charging 
the 12-volt battery from another 
vehicle in an emergency. It cannot 
be used to jump start another 
vehicle.

tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from 
under the hood, do not open the 
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●After the hybrid system has 
been turned off , check that the 
“READY” indicator is off.
When the hybrid system is oper-
ating, the gasoline engine may 
automatically start, or the cool-
ing fan may suddenly operate 
even if the gasoline engine 
stops. Do not touch or approach 
rotating parts such as the fan, 
which may lead to fingers or 
clothing (especially a tie, a scarf 
or a muffler) getting caught, 
resulting in serious injury.
●Do not loosen the coolant reser-
voir cap while the hybrid system 
and radiator are hot.
High temperature steam or 
coolant could spray out.
NOTICE
■When adding engine/power
