■Operating switches of the air conditioning system operation panel
●The pop-up display function that displays when the air conditioning settings
are changed using the air conditioning system switches can be turned off in
the “Meter Customize” settings. (P. 260)
■Eco score (A/C score)
●The setting status of the following air conditioning system functions are
reflected in the score.
• Temperature setting
• Fan speed setting
• Outside air and recirculated air modes
• “A/C” button
• Front seat concentrated airflow mode (S-FLOW)
• “CLIMATE PREFERENCE”
●The Eco score (A/C score) is evaluated according to the ambient tempera-
ture and cabin temperature. Accordingly, even if the same settings are
always used for the air conditioning system, the evaluation will change
according to such factors as the season and weather.
●When the air conditioning system is not being used or the airflow mode is
set to or , the Eco score (A/C score) is not evaluated. (While the
air conditioning system is not evaluated, its usage status is not reflected in
the total Eco score result.)
●The Eco score (A/C score) is a function that helps select an air conditioning
system setting which reduces electricity and fuel consumption, not a func-
tion that satisfies both comfortability and low fuel consumption. ●When the air conditioning system
switches are operated to change the air
conditioning settings while a screen
other than the air conditioning system
settings screen is displayed on the multi-
information display, a pop-up display for
the air conditioning settings contents is
displayed. However, air conditioning
system settings cannot be changed on
the pop-up display.

Operation of each component
■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. 295)
