8-6 Climate Controls
O (On/Off): Press to turn the
climate control system on or
off. Outside air still enters the
vehicle, and is directed to the
floor. This direction can be changed
by pressing the mode button.
Recirculation can be selected once
you have selected vent or bi-level
mode. The temperature can also be
adjusted using either temperature
button. If the air delivery mode or
temperature settings are adjusted
with the system off, the display
illuminates briefly to show the
settings and then returns to off.
The system can be turned back
on by pressing either
O , D , C , # ,
the defrost or the AUTO button.
Driver and Passenger Side
Temperature Controls
The driver and passenger side
temperature buttons are used to
adjust the temperature of the air
coming through the system on
the driver or passenger side of
the vehicle. The temperature can
be adjusted even if the system is
turned off. This is possible since
outside air always flows through
the system as the vehicle is
moving forward unless it is
set to recirculation mode.
See “Recirculation” later in
this section.
Press the + or − buttons to increase
or decrease the cabin temperature.
The driver side or passenger side
temperature display shows the
temperature setting increasing or
decreasing.
The passenger temperature
setting can be set to match the
driver temperature setting by
pressing the PASS button and
turning off the PASS indicator.
When the passenger temperature
setting is set different than the driver
setting, the indicator on the PASS
button illuminates and both the
driver side and passenger side
temperature displays are shown.
When in defrost mode the
passenger temperature setting
cannot be changed.
