Operation of each component
PRIUS_OM_OM47F32E_(EE)■Note for the entry function
●Even 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.
●Do 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.
●As long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.
●Even 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.
●The 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.)
●If 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.)
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
●On 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.
●If 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. 189)

1923-2. Opening, closing and locking the doors
PRIUS_OM_OM47F32E_(EE)●If 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.
●The 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.
●A 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.
●If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
●The smart entry & start system can be deactivated in advance. (P. 670)
■To 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.)
■If the smart entry & start system does not operate properly
●Locking and unlocking the doors: Use the mechanical key. (P. 636)
●Starting the hybrid system: P. 637
■Customization
Settings (e.g. smart entry & start system) can be changed.
(Customizable features: P. 670)
■If the smart entry & start system has been deactivated in a customized
setting
