Operation of each component
QNote for the entry function
OEven when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, floor, or in the door pockets
or glove box when the hybrid system is started or power switch modes
are changed.
ODo not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
OAs long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.
OEven if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
OThe doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
30 seconds if the doors are not opened and closed.)
OIf the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
OTouching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
OOn some models: When the lock operation is performed using the lock sen-
sor, recognition signals will be shown up to two consecutive times. After this,
no recognition signals will be given.
OIf the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set electronic key to battery-saving mode to disable the smart entry &
start system. (P. 285)

2884-2. Opening, closing and locking the doors
Prius Plug-in Hybrid_OM_OM47E75E_(EE)OIf the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
OThe lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
OA sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
OIf there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
QWhen the vehicle is not driven for extended periods
OTo prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
OThe smart entry & start system can be deactivated in advance. (P. 724)
QTo operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention may not operate.)

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

battery) drops to low.
QConditions affecting operation
The system may not start in the following situations:
OThe charge level of the hybrid battery (traction battery) is low
OThe outside temperature is extremely low
OWhen the hybrid system is cool (for example, after being left for a long time
in low temperatures)
QWindshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
QUsing the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.
QSecurity feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The emergency flashers flash to indicate that the doors have been locked
or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)
