the air conditioning is on and the outside temperature
drops below a temperature which is too cool for air
conditioning to be effective, the snowake symbol will
turn off to let you know 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 snowake symbol will turn off,
but the A/C compressor will still run to help prevent
fogging.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
your vehicle to cool down. Then keep your windows
closed for the air conditioner to work its best.
