AIR CONDITIONING
258
If manual switching of air intake is de-
sired —
Each time you push the air intake control
button, the mode changes in order from
the RECIRCULATED AIR mode to AUTO-
MATIC mode to OUTSIDE AIR mode, then
back to the RECIRCULATED AIR mode.
Each indicator light shows which mode is
now selected.
1 RECIRCULATED AIR mode —If
quick circulation of cooled air is de-
sired, select this mode.
2 EXHAUST GAS AUTOMATIC mode (on some models) — If the outside
air contains harmful substances like
exhaust gas (i.e., when the vehicle
running just in front of your vehicle ac-
celerates rapidly), the system
changes automatically from the
OUTSIDE AIR mode (with indicators
2 and3on) to the RECIRCU-
LATED AIR mode (with indicators
1 and2on).
3 OUTSIDE AIR mode — The system
will take fresh outside air into the ve-
hicle. Turning off the air conditioning manually
will cancel the EXHAUST GAS AUTO-
MATIC mode. If you select the “AUTO”
mode during fan operating, the air condi-
tioning turns on and the EXHAUST GAS
AUTOMATIC mode will operate.
For normal use, it is best to keep the air in-
take control button set to OUTSIDE AIR
mode. If recirculated air is used during
heating, the windows will fog up more easi-
ly.

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.

ger, beeps will stop sounding and the mul-

ners and the rear corners of the vehicle.
CAUTION
To avoid an accident or injury, ob-
serve the following instructions, and
then drive slowly using the brakes
while visually confirming a safe dis-
tance around your vehicle.
DThe sensor detection range is limit-
ed around the bumper. Be sure to
visually confirm safety outside the
sensor detection. For the sensor
detection range, see “ — Detection
range of sensors” on page 284.

detect obstacles.
DDepending on the shape of the ob-
stacle, indicators or beeps may not
warn you properly, and the detec-
tion range may also be shortened.
DIt might be difficult to hear beeps
due to the volume of audio or air
flow noise of the air conditioning.
