Prius Plug-in Hybrid_OM_OM47E75E_(EE)
WARNING
Observe the following precautions.
Failing to do so may result in death or serious injury.
Q Closing the windows
O The driver is responsible for all the power window operations, including the
operation for the passengers. In order to prevent accidental op eration,
especially by a child, do not let a child operate the power win dows. It is
possible for children and other passengers to have body parts c aught in
the power window. Also, when riding with a child, it is recomme nded to use
the window lock switch. ( P. 303)
O When using the wireless remote control or mechanical key and operating
the power windows, operate the power window after checking to m ake
sure that there is no possibility of any passenger having any o f their body
parts caught in the side window. Also do not let a child operat e side win-
dow by the wireless remote control or mechanical key. It is pos sible for
children and other passengers to get caught in the power window .
O When exiting the vehicle, turn the power switch off, carry the key and exit
the vehicle along with the child. There may be accidental opera tion, due to
mischief, etc., that may possibly lead to an accident.
Q Jam protection function
O Never use any part of your body to intentionally activate the jam protection
function.
O The jam protection function may not work if something gets jammed just
before the side window is fully closed. Be careful not to get a ny part of
your body jammed in the side window.
Q Catch protection function
O Never use any part of your body or clothing to intentionally activate the
catch protection function.
O The catch protection function may not work if something gets caught just
before the side window is fully opened. Be careful not to get a ny part of
your body or clothing caught in the side window.
O Check to make sure that all passengers
do not have any part of their body in a

QHeating
O In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
O In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside h eat
exchanger by operating the Remote Air Conditioning System befor e driv-
ing ( P. 535). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. There fore,
the set heating performance may not be achieved even if the fan speed
setting is increased.
O In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approx imately -10°C (14°F) or low
• is operating
Q Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.Outside heat exchanger

Remote Air Conditioning System
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the hybrid
battery (traction battery) will be suppressed to allow you to use elec-
tricity from an external power source.
Charging will be conducted automatically after the Remote Air Condition-
ing System is stopped.
Check the temperature setting of the air conditioning system.
(P. 522)
The Remote Air Conditioning System will operate in accordance with the
temperature settings of the air conditioning system.
Press and hold “A/C” on the wire-
less remote control to operate the
Remote Air Conditioning System.
The system will shut off if a door is
opened.
The system can be stopped by
pressing “A/C” twice.
The Remote Air Conditioning System uses electrical energy
stored in the hybrid battery (traction battery) and allows the air
conditioning to be operated by remote control.

QWhen using the Remote Air Conditioning System
A charging message will be displayed on the multi-information display. Differ-
ent messages will be displayed depending on when the Remote Air Condi-
tioning System was started (after charging or during charging).
QWhile the Remote Air Conditioning System is operating
ODepending on the operating condition of the Remote Air Conditioning Sys-
tem, the electric fan may spin and an operating noise may be heard.
However, this does not indicate a malfunction.
OThe Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery
becomes low.
OThe headlights, windshield wiper, combination meter, etc. will not operate
while the Remote Air Conditioning System is operating.

Maintenance and care
QWhen opening the cover of the positive (+) battery terminal
Q Before recharging
When recharging, the 12-volt battery produces hydrogen gas whic h is flam-
mable and explosive. Therefore, observe the following precautio ns before
recharging:
O If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
O Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
Q After recharging/reconnecting the 12-volt battery
O Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unloc k the doors.
O Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. H owever, the
hybrid system will operate normally from the second attempt.
O The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power switch before disconnect the 12-volt battery. Take ex tra care
when connecting the 12-volt battery if the power switch mode pr ior to dis-
charge is unknown.
If the system will not start even after multiple attempts at al l methods above,
contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.

Q When recharging or replacing the 12-volt battery
O 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. Us e the wire-
less remote control or the mechanical key to lock or unlock the doors.
O 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.
O 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 opera te the
charging port lid or charging connector lock switch again.
O 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-vol t 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.
O 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 thi s case, the vehicle
cannot be towed without lifting both front wheels because the f ront wheels
will be locked. ( P. 650)
Q When replacing the 12-volt battery
O Use a 12-volt battery that conforms to European regulations.
O 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, a nd perfor-
mance rating (CCA) is equivalent (295A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly se cured.
• If the 20 hour rate capacity is low, even if the time period w here the vehi-
cle is not used is a short time, the 12-volt battery may discha rge and the
hybrid system may not be able to start.
O For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
