Climate Controls
For more information on the vehicle’s climate control
system, see “Climate Control System” in the owner
manual.
Electric Air Conditioning Compressor
This hybrid vehicle has a electrically powered air
conditioning compressor. This allows for continuous
air conditioning operation and passenger comfort,
even while the hybrid engine cycles on and off.When operating the climate control system, select the
AUTO mode and the desired temperature setting.
The climate control system automatically adjusts 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.
