Operation of each component
PRIUS +_OM_OM47D30E_(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, luggage room, 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. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
●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 doors 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 or unlock sensor while wearing gloves may delay or
prevent lock or unlock operation.
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that 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 the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 155)
●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 (if equipped) 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, or
use the lock sensor on the lower part of the door handle.

1583-2. Opening, closing and locking the doors
PRIUS +_OM_OM47D30E_(EE)●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. 539)
■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.

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.)
