Automatic Air Conditioning Controls
84If manual on±off of the air conditioning is
desired ±
Push the ºA/Cº button to turn the air condi-
tioning on and push it again to turn the air
conditioning off. If you turn off the air condi-
tioning manually, the EXHAUST GAS AUTO-
MATIC 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 indica-
tor on the A/C button is off and the EXHAUST
GAS AUTOMATIC indicator light remains on.
However, the EXHAUST GAS AUTOMATIC
mode does not operate. When the air condi-
tioning turns on as with the raised tempera-
ture, 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 condition-
ing off once it is no longer required. This will
improve fuel economy. The air conditioning
can be used for year±round automatic tem-
perature control including cooling and dehu-
midifying operation.If the air conditioning compressor does not
operate, the indicator of the ºA/Cº button will
blink. If the indicator of the ºA/Cº button
blinks even when the ºA/Cº button is pushed
again, have the compressor checked by
your nearest Lexus dealer.
