Air Conditioning

#
(Air Conditioning): Press this button to turn the air
conditioning (A/C) compressor on and off. The
snowflake symbol will appear on the display when the
A/C is on.
Pressing this button when the outside temperature is
too cool for air conditioning to be effective will make the
snowflake symbol flash three times and then turn off
to let you know that the air conditioning mode is
not available. If the air conditioning is on and the outside
temperature drops below a temperature which is too
cool for air conditioning to be effective, the snowflake
symbol will turn off to let you know that the air
conditioning mode has been canceled.
When air conditioning is selected or in AUTO mode, the
system will run the air conditioning automatically to cool
and dehumidify the air entering the vehicle. If you select
A/C off while in front defrost, defog or recirculation, the
A/C snowflake symbol will turn off, but the A/C
compressor will still run to help prevent fogging.
