AIR CONDITIONING
259
To change the sensitivity of the sensor
switching between the RECIRCU-
LATED AIR and OUTSIDE AIR in the AU-
TOMATIC mode, push the air intake
control button and hold it for a few sec-
onds.
The “Smog Sensor” screen will be dis-
played.
The sensitivity of the sensor can be ad-
justed only while the vehicle has been
stopped.
The sensitivity of the touch−screen button
is set to be higher toward “HI” and lower to-
ward “LO”.
Touch the desired button on the screen.
When you push the “AUTO”button, the
above screen goes off. If manual on
−off of the air conditioning
is desired —
Touch “A/C” to turn the air conditioning on
and touch it again to turn the air condition-
ing off. If you turn off the air conditioning
manually, the EXHAUST GAS AUTOMAT-
IC mode will be cancelled.
If the outside temperature is below 0 _C
(32 _F), the air conditioning will turn off au-
tomatically. At this time, the indicator on
“A/C” is off and the EXHAUST GAS AU-
TOMATIC indicator light remains on. How-
ever, the EXHAUST GAS AUTOMATIC
mode does not operate. When the air con-
ditioning turns on as with the raised tem-
perature, the EXHAUST GAS AUTOMAT-
IC mode resumes.
If the system is used for ventilation, heat-
ing in dry weather or removing frost or ex-
terior fog on the windshield, turn the air
conditioning off once it is no longer re-
quired. This will improve fuel economy.
The air conditioning can be used for year −
round automatic temperature control in-
cluding cooling and dehumidifying opera-
tion.
If the air conditioning compressor does not
operate, the indicator of “A/C”will blink.
If the indicator of “A/C”blinks even when
“A/C” is touched again, have the com-
pressor checked by your Lexus dealer.
