Climate Control Function With
Stop/Start (If Equipped)
The climate control system depends
on other vehicle systems for heat
and power input. The climate control
system will balance stop/start
efficiency with air conditioning
comfort and defog operation.
Certain climate control settings can
result in fewer auto stops.
The following are climate control
settings that result in fewer auto
stops:
.The defrost mode.
. High fan speed settings.
. Extreme temperature settings.
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 indicator light is on or
AUTO is displayed on the screen,

operation. If the air delivery mode or
fan setting is manually adjusted, the auto indicator turns off and the
display will show the selected
settings.
For automatic operation:
1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Then
adjust the temperature as
needed for best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on. Press

quickly cool the inside of the
vehicle.
@(Recirculation) : Press to
alternate between recirculating air
inside the vehicle or pulling in

inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or
on, see “Climate and Air Quality”
