Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
9
reverse. After installing, check that the fixed pins are inserted
securely.
Once the hybrid system starts, have the vehicle inspected at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional as soon as possible.
■ When opening the cover of the positive (+) battery terminal
P. 575
■ 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 discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical 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 stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
●Some systems may require initialization. (P. 717)
■ 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 dealer or repairer, or another duly qualified and equipped
professional.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery 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 vehicle is left for a long time, the 12-volt
battery 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 the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
●It may be impossible to unlock the charging port lid or locking and unlocking
the charging connector immediately after the 12-volt battery is reconnected.
In this case, carry the electronic key on your person and operate the
charging port lid or charging connector lock switch again.
●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 battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
● If the 12-volt battery discharges while the shift position is in P, 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. (P. 634)
■ When exchanging 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 perfor-
mance rating (CCA) is equivalent (295A) 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 the
hybrid system may not be able to start.
● For details, consult any authorized Toyota dealer or repairer, or another duly
8
qualified and equipped professional.

WARNING
■ When removing the 12-volt battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts 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 “+” termi-
nal 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.
●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 poisonous and corrosive acidic electrolyte,
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
