AIR CONDITIONING SYSTEM
OPERATING HINTS
INFORMATION
●Operation of the air conditioning system
in Eco drive mode (vehicles with hybrid
system)
In Eco drive mode, the air conditioning
system is controlled as follows to priori-
tize fuel efficiency:
• Engine speed and compressor opera-
tion controlled to restrict heating/cool-
ing capacity
• Fan speed restricted when automatic
mode is selected
To improve air conditioning performance,
perform the following operations:
• Adjust the fan speed
• Turn off Eco drive mode
●Customization (vehicles with hybrid sys-
tem)
The air conditioning control restriction of
Eco drive mode can be changed to the
same setting as that used in normal drive
mode. For details, refer to "Owner' s Man-
ual".
Changing the air conditioning restriction
will slightly reduce the Eco drive mode' s
fuel efficiency when compared to before
the change was made.

1. AIR CONDITIONING SYSTEM OPERATION
INFORMATION
●Registering air conditioning settings to
electronic keys
• Unlocking the vehicle using an elec-
tronic key and turning the "POWER"
<"ENGINE START STOP"> switch to
ON <IGNITION ON> mode will recall
that key' s registered air conditioning
settings.
• When the "POWER" <"ENGINE
START STOP"> switch is turned off, the
current air conditioning settings will
automatically be registered to the elec-
tronic key that was used to unlock the
vehicle.
The system may not operate correctly if
more than 1 electronic key is in the vicin-
ity or if the smart access system with
push-button start is used to unlock a
passenger door.
Settings for the electronic key and the
corresponding door can be changed.
Contact your Lexus dealer.
●Using the automatic mode
• Fan speed is adjusted automatically in
accordance with the temperature set-
ting and ambient conditions. As a result,
the following may occur:
• Immediately after the "AUTO" button is
pressed, the fan may stop for a while
until warm or cool air is ready to flow.
• Cool air may flow to the area around
the upper body when the heater is on.
●Using the system in recirculated air mode
• The windows will fog up more easily if
the recirculated air mode is used for an
extended period.
●Switching between outside air and recir-
culated air modes
• Recirculated air mode or outside air
mode may be automatically switched in
accordance with the temperature set-
ting and the inside temperature.
