Display Function
Each time the temperature, mode,
or fan control buttons are pressed,
the climate control display shows
that function along with the inside
temperature setting. The outside
temperature is displayed on the
instrument panel cluster.
O (On/Off): Press to turn the
climate control system on or off.
While the system is off, outside air
still enters through the floor outlets,
but the air delivery mode can be
adjusted.
The climate control system will
also turn on if either the fan control,
defrost, AUTO, or air conditioning
buttons are pressed.
Automatic Operation
AUTO (Automatic): The system
automatically controls the inside
temperature, the air delivery,
and the fan speed.
To use automatic mode:
1. Press the AUTO button.
When AUTO is selected,
the current temperature(s)
selected and AUTO is shown
on the display. The current
air delivery mode and fan speed
also appear for approximately
five seconds.
When AUTO is selected, the
air conditioning and air inlet
are automatically controlled.
The air conditioning runs when
the outside temperature is over
40°F (4°C). The system is
automatically set to outside
air, unless it is hot outside and
then the air inlet changes to
recirculation mode to help quickly
cool the vehicle. The recirculation
indicator light will come on.
Instrument Panel
2. Set the temperature for the driver
and passenger.
To find a comfortable setting,
start with a 73°F (22°C)
temperature setting and allow
about 20 minutes for the system
to regulate. Use the driver's side
or passenger side temperature
buttons to adjust the temperature
setting as necessary. The system
will remain at the selected setting.
Choosing the warmest or coolest
temperatures does not cause
the vehicle to heat or cool more
quickly.
To avoid blowing cold air in
cold weather, the system delays
turning on the fan until warm air is
available. Press the fan control to
override this delay and select the
fan speed.
