zUsually the system will turn off automati-
cally after approximately 1 to 3 minutes.
z In the Eco drive mode, the air conditioning
system is controlled as follows to prioritize
fuel efficiency:
• Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected z
To improve air conditioning performance,
perform the following operations:
• Adjust the fan speed and temperature
• Turn off Eco drive mode (refer to
“Owner ’s Manual”.)
z Unlocking the vehicle using an electronic
key and turning the “START STOP
ENGINE” <“POWER”> switch to IGNI-
TION ON mode will recall that key’s
registered air conditioning settings.
z When the “START STOP ENGINE”
<“POWER”> switch is turned off, the cur-
rent air conditioning settings will automati-
cally be registered to the electronic key
that was used to unlock the vehicle.
The system may not operate correctly if
more than one 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 cor-
responding door can be changed. Contact
your Lexus dealer.

zFan speed is adjusted automatically
according to the temperature setting and
the ambient conditions.
z Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after “A U T O ” is pressed.
z The windows will easily fog up when the
humidity in the vehicle is high. Selecting
“A / C ” on will dehumidify the air from the
outlets and defog the windshield effectively.
z If “A / C ” is switched off, the windows may
fog up more easily.
z The windows may fog up if the recirculated
air mode is used. z
When automatic mode is set, the humidity
sensor (see page 305) detects fog on the
windshield and controls the air condition-
ing system to prevent fog.
z When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode button to the recircu-
lated air mode. This is effective in prevent-
ing outside air from entering the vehicle
interior. During cooling operation, setting
the recirculated air mode will also cool the
vehicle interior effectively.
z Outside/recirculated air mode may auto-
matically switch depe nding on the temper-
ature setting or the inside temperature.

WINDOWS
CAUTION
●To prevent the windshield from fogging
up
• Do not use the windshield air flow but- ton during cool air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
can cause the outer surface of the wind-
shield to fog up, blocking your vision.
