Driver and Passenger Side Temperature
Control
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.
The passenger's temperature setting can be set to
match the driver's temperature setting by pressing the
PASS button and turning off the PASS indicator. When
the passenger's temperature setting is set different than
the driver's 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.
Automatic Operation
AUTO (Automatic): When automatic operation is active
the system will control the inside temperature, the air
delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will be
lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over about 4°C
(40°F). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down the vehicle. The light on the
button comes on in recirculation.
