Display: In the full AUTO mode, the automatic dual
climate control system display will show the driver set
temperature and an arrow pointing to the driver’s side. An
arrow pointing to the passenger’s side will display
if both
sides are set to the same temperature.
If the temperature
settings are not the same, the opposite side temperature
setting will be displayed for an additional five seconds.
During the five second status display the current mode
and blower speed will be displayed.
Driver’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the driver’s side of the vehicle.
The display will show the temperature setting decreasing
or increasing and an arrow pointing to the driver. The
temperature can be adjusted even
if the system is
turned
off. If the passenger’s set temperature has not
been adjusted this knob controls both the driver’s
and passenger’s air temperature. The temperature to
the rear seat area is controlled by using this knob.
Passenger’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or
lower the temperature on the passenger’s side of the
vehicle. The display will show the temperature
setting decreasing or increasing and an arrow pointing
to the passenger. The temperature can be adjusted
even
if the system is turned off. Once this knob is used,
the passenger’s temperature will remain independent
of the driver’s until the AUTO button is pressed and held
for approximately four seconds.
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 driver’s set temperature,
delivery mode and fan speed. Press the AUTO
button again within five seconds to display
the passenger’s set temperature.
If the driver and passenger’s temperature settings
are not the same, the opposite side temperature
setting will be displayed for an additional five
seconds. To make the passenger’s temperature the
same as the driver’s press and hold the AUTO
button for approximately four 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 approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will illuminate in recirculation.
