Climate Control Influence on
eAssist Operation and Fuel
Economy (If Equipped)
The climate control system depends
on 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 following.
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.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When the AUTO indicator light is
on, the system is in full automatic
operation. If the air delivery mode,
fan speed, recirculation, or air
conditioning setting is adjusted, the
AUTO indicator turns off and the
selected settings will appear on the
display.
To place the system in
automatic mode:
1. Press AUTO.
2. Set the temperature. Allow the
system time to stabilize. Adjust
the temperature as needed for
best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation

warm weather. The recirculation
light will not come on. Press
select recirculation; press it again to
select outside air.
