When operating the climate control system, select the
AUTO mode and the desired temperature setting.
The climate control system will automatically adjust the
fan speed and airflow direction. The climate control
system continues to adjust the climate control settings
chosen for best use of electrical power.
To get maximum engine off time, select a warmer
temperature setting or turn off the air conditioning to
shut off the compressor. Continuous air conditioning use
can cause the engine to autostart more frequently.
Some noise may be heard occasionally from the
compressor, especially when air conditioning use is high
and the engine has turned off.
