Outside Air Temperature Display
A new outside temperature reading will be displayed if
the vehicle has been off for more than three hours. If the
vehicle has been off for less than three hours, the old
temperature reading may be displayed because
underhood heat is affecting the true outside temperature.
Since underhood heat can also affect the outside
temperature while the engine is running, it may take
several minutes of driving before the display updates to
the actual outside temperature.

control system. Outside air will still enter the vehicle, and
will be directed to the oor. Press the AUTO button,
the mode button, the fan arrows, or either temperature
knob to turn the system on.

delivery mode to the oor, instrument panel, or
windshield outlets. The system will stay in the selected
mode until the mode button is pressed again or the
AUTO button is pressed.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 the word DRIVER will appear on
the display. This knob can also adjust the passenger’s
side temperature setting simultaneously if the two
zones are linked. The words DRIVER and PASS will
then appear on the display.
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 the word PASS will
appear on the display. The passenger’s temperature
setting can be set to match and link to the driver’s
temperature setting by pressing and holding the AUTO
button for three seconds. Now, by adjusting the
driver’s side temperature setting, the passenger’s side
temperature setting will follow and both DRIVER
and PASS will appear on the display. The passenger’s
side temperature setting also resets and relinks to
the driver’s side temperature setting if the vehicle has
been off for more than two hours.
