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
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's 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
decreasing or increasing.
