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.

8-4 Climate Controls
0(Defrost):Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and
ice from the windshield before
defrosting.
For eAssist vehicles that have the
auto defog feature, auto stops can
occur in defrost mode. In this mode,
the auto stops are shorter and less
frequent than other air delivery
modes to prevent instant fogging.
A/C (Comfort Air Conditioning):

may occur if the climate control
system determines the a/c
compressor can be shut off and still
maintain comfort levels with minimal
windshield fogging.
Eco
#(Eco Air Conditioning, If
Equipped): This setting balances
fuel economy and air conditioning
comfort. In warm weather
conditions, auto stops may occur
more frequently and the vehicle
interior may be warmer as
compared to the comfort air
conditioning. The eco a/c setting
allows higher humidity inside the
vehicle and window fogging before
the engine restarts.
Pressing the
0button during an
auto stop will restart the engine to
prevent window fogging. To reach
comfort levels quickly during an
auto stop, the engine will restart if the air conditioner is off and the
AUTO, eco
#, or A/C is selected.
The engine also restarts if the
Ois
pressed on and the system is set to
AUTO, eco
#, or A/C.
