Automatic Climate Control System
The heating, cooling, and ventilation in your vehicle can
be automatically controlled with this system.
Climate Control Influence on Hybrid
Operation and Fuel Economy
The climate control system is dependent upon other
vehicle systems for heat and power input. Certain
climate control settings can lead to higher fuel usage
and/or fewer Auto Stops.
The following are climate control settings that use
more fuel:
• Normal air conditioning mode.
• The defrost mode.
• Extreme temperature settings, such as
60°F (15°C) / 90F (32°C).
• High fan speed settings.
To help reduce fuel usage:
• Use the full automatic control as described under
Automatic Operation.
• Use hybrid air conditioning, instead of the normal
air conditioning.
• Select a temperature setting that is higher in hot
weather and lower in cold weather.
• Only use defrost to clear the windows.
