The temperature can also be adjusted using either
temperature knob. Press the up or down arrows on the
fan switch, the defrost button, the AUTO button, driver
side temperature knob, or the air conditioning button to
turn the system on when it is off.
Driver and Passenger Side
Temperature Knob
The driver and passenger side temperature knobs 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.
Turn the knob clockwise or counterclockwise to
increase or decrease the cabin temperature. The
display will show the temperature setting increasing or
decreasing.
Set the passenger's temperature setting to match the
driver temperature setting by pressing the passenger
power knob.
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
appear. The current delivery mode and fan speed
will also be displayed for approximately
five 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.
