Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will automatically
cool the vehicle if the temperature is greater than
90°F (32°C) and heat the vehicle if the temperature is
below 37°F (3°C). If the temperature is between
37°F (3°C) and 90°F (32°C), the last control setting
selected when the engine was running will be used.
Normal operation and the last setting of the climate
control system will return after the ignition key is turned
to the C (RUN) position. SeeRemote Keyless Entry
System Operation on page 2-6for more information.
Operation
(
(Off):Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed will be temporarily reduced between
the transition to a new mode. The fan will resume when
the new mode is complete.
If the air ow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
Temperature Control:Turn the center knob clockwise
or counterclockwise to warm or cool the air coming
through the outlets.
Use the right knob to select from the following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city traffic, and the
vehicle is stopped and idling, or the weather is hot,
turn on the recirculation mode.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed to
the oor outlets.
3-23
After your vehicle is started, the display will show the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
AUTO
#(Automatic Air Conditioning):If the
AUTO position is selected on the fan or mode control,
the system will automatically control the air conditioning
compressor. The A/C compressor will run automatically
even at cool outside temperatures in order to
dehumidify the air. The A/C indicator light will be lit
when the system is operating automatically, even
at near freezing outside temperatures. Press the
A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog or
defrost modes, the A/C compressor will run
automatically in damp cool conditions.
h(Auto Recirculation):If the AUTO position is
selected on either the fan or mode control, the system
will automatically control the air inlet to supply fresh
outside air or recirculate the interior air to cool the car
faster. The indicator light on the recirculation button
will light whenever the system switches to recirculation.
You may force outside air by pressing the button
when the light is lit. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO operation.
Manual Operation
9(Fan):Turn the left knob either to the left or right to
adjust the fan speed. Turning this control completely
counterclockwise will turn on the automatic fan operation.
If the air ow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
9(Off):Turn the left control to this position to turn the
entire climate control system off.
To change the current mode, select one of the following
positions using the right control:
F(Vent):Turn the control to this mode to direct air to
the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to direct
approximately half of the air to the instrument panel
outlets and most of the remaining air to the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
