Climate Control Influence on eAssist Operation and Fuel Economy (If Equipped)
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.
