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).

8-8 Climate Controls
To change the current mode, select
one of the following:
Y(Vent):Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
C(Tri‐Level): Air is divided
between the windshield, instrument
panel, and floor outlets.
[(Floor): Air is directed to the
floor outlets.
-(Defog): Clears the windows of
fog or moisture. Air is directed to the
windshield and floor outlets.
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.
#(Comfort Air Conditioning):
Press to turn the air conditioning
system on or off. If the climate
control system is turned off or the
outside temperature falls below
freezing, the air conditioner will
not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically 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#(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
