AIR CONDITIONING
262To change the sensitivity of the sensor switching between
the RECIRCULATED AIR and OUTSIDE AIR in the
AUTOMATIC mode, push the air intake control button and
hold it for a few seconds. The display changes to the one
illustrated below.
The sensitivity of the sensor can be adjusted only while the
vehicle has been stopped.
G21023
The sensitivity of the switches is set to be higher toward “HI”
and lower toward “LO”.
Touch the desired switch on the screen.
When you push any button except the air intake control button,
the above screen goes off.If manual on−off of the air conditioning is desired—
Touch the ”A/C” switch to turn the air conditioning on and touch
it again to turn the air conditioning off. If you turn off the air
conditioning manually, the EXHAUST GAS AUTOMATIC
mode will be cancelled.
If the outside temperature is lowered down to around 0C
(32F), the air conditioning will turn off automatically. At this
time, the indicator on the A/C switch is off and the EXHAUST
GAS AUTOMATIC indicator light remains on. However, the
EXHAUST GAS AUTOMATIC mode does not operate. When
the air conditioning turns on as with the raised temperature, the
EXHAUST GAS AUTOMATIC mode resumes.
If the system is used for ventilation, heating in dry weather or
removing frost or exterior fog on the windshield, turn the air
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for year−round
automatic temperature control including cooling and
dehumidifying operation.
If the air conditioning compressor does not operate, the
indicator of the ”A/C” switch will blink. If the indicator of the
”A/C” switch blinks even when the ”A/C” switch is touched
again, have the compressor checked by your nearest Lexus
dealer.

(d) Operating tips
To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
If air flow control is not satisfactory, check the dashboard
vents and rear vents. (See (e) “Center vents, side vents and
rear vents”.)
Only humid days, do not blow cold air on the windshield.
The windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on the windows.
When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
control button be set to the OUTSIDE AIR mode to take in
the fresh air and the fan speed selector to any setting except
OFF.If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.

For quick heating, select RECIRCULATED AIR mode for a
few minutes. To keep the windows from fogging, select

warmed.
Touch the “A/C” switch on for dehumidified heating.
Choose floor/windshield air flow to heat the vehicle interior
while defrosting or defogging the windshield.
