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.

8-4 Climate Controls
For eAssist vehicles, 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 flash fogging.
#(Comfort Air Conditioning):
Press to turn the air conditioning on
or off. The button indicator light
turns blue when the a/c is on. If the
fan is turned off or the outside
temperature falls below freezing, the
air conditioner will not run.
Press AUTO to return to automatic
operation and the air conditioner
runs as needed. When the indicator
light is on, the air conditioner runs
automatically to cool the air inside
the vehicle or to dry the air needed
to defog the windshield faster.
For eAssist vehicles, an auto stop
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 Air Conditioning, If
Equipped): Press
#to turn on the
eco air conditioning. The button
indicator light turns green when eco
a/c is on. 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. This setting allows
higher humidity inside the vehicle
and window fogging before the
engine restarts.
Pressing the
0button during an
auto stop may 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
AUTO, Eco
#, or Comfort#is
selected.
.The climate control power is
turned on and the system is set
to AUTO, Eco
#, or Comfort
#mode.
.The temperature control is
adjusted cooler by more than
0.5°C (1°F).
h(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated to
quickly cool the inside of the vehicle
or prevent outside air and odors
from entering.
Auto Defog: The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. For eAssist vehicles,
when this mode is in use auto stops

defogger on or off.
The rear window defogger turns off
automatically after about
10 minutes. If turned on again, it

rear window defogger may stay on
continuously.
For vehicles with heated outside
rearview mirrors, they turn on with
the rear window defogger and help
to clear fog or frost from the surface
of the mirror. See Heated Mirrors on
page 2‑16. Notice:
Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
Remote Start Climate Control
Operation (If Equipped): For
vehicles with the remote start
feature, the climate control system
may run when the vehicle is started
remotely. The system uses the
driver ’s previous settings to heat or
cool the inside of the vehicle. The
rear defog may come on during
remote start based on cold ambient
conditions. If the vehicle has heated
seats, they may come on during a
remote start. The heated seat
indicator lights do not come on
during a remote start. See Remote
Vehicle Start on page 2‑8 and
Heated Front Seats on page 3‑6.
Sensors
The solar sensor on top of the
instrument panel near the
windshield monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the dual
automatic climate control system
may not work properly.
