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 60°F (15°C) /
90°F (32°C).
.
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.
