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:

• Comfort air conditioning mode.

• The Defrost mode.

• Extreme temperature settings, such as 15°C (60°F) or 32°C (90°F).

• High fan speed settings.

To help reduce fuel usage:

• Use the full automatic control as described under “Automatic Operation”.

• Use eco air conditioning, instead of the comfort air conditioning.

• Select a temperature setting that is higher in hot weather and lower in cold weather.

• Turn off the air conditioning when it is not needed.

• Only use defrost to clear the windows.
