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 an
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. At mild temperatures, select a
warmer air conditioner temperature
or turn the air conditioner off to get
maximum fuel economy. Continuous
air conditioner use can cause the
vehicle to Auto Start more
frequently. During hot weather,
driving with the windows closed and
the air conditioner set to Auto mode,
will result in better Hybrid system
performance.
Some noise may be heard
occasionally from the compressor,
especially when air conditioning use
is high and the engine has
turned off.
