CLIMATE CONTROLS 159
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.
The following climate control settings
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 AUTO is lit, all four functions
operate automatically. Each function
can also be manually set and the
selected setting is displayed.
Functions not manually set will continue to be automatically
controlled, even if the AUTO indicator
is not lit.
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
@to select
recirculation; press it again to select
outside air.
English units can be changed to
metric units through the instrument
cluster. See “Settings”under
Instrument Cluster 0113.
OFF : Press to turn the fan on or off.
When off is selected, the system will
stop air from flowing into the cabin.
If on is selected, or any other button
press occurs, the climate control
system will turn on and operate to the current setting. The temperature
control and air delivery mode can still
be adjusted.
worx:
The temperature can be
adjusted separately for the driver and
the passenger. Press to increase or
decrease the temperature. Press and
hold to rapidly increase or decrease
the temperature.
SYNC : Press SYNC to link all climate
zone settings to the driver settings.
The SYNC indicator will be lit. Adjust
the driver side temperature control to
change the linked temperature. When
the passenger settings are adjusted,

automatically to cool the air inside
the vehicle or to dry the air needed to
defog the windshield faster.
Automatic Air Recirculation : When
the AUTO indicator light is on, the air
is automatically recirculated as
needed to help quickly cool the inside
of the vehicle.
@: Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. The indicator
light on the button is lit when
recirculation mode is active. This
helps to quickly cool the air inside the

recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
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. 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”
under Vehicle Personalization 0135.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off. An indicator light
