MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
Fan speed control
Controls the volume of air circulated
in the vehicle.
Temperature control knob
Controls the temperature of the
airflow inside the vehicle.
Mode Selector Control
Controls the direction of the airflow
to the inside of the vehicle.
•Max A/C – Distributes recirculated air through the instrument panel
registers. The A/C compressor will only function if the outside
temperature is above approximately 2°C (36°F). Max A/C is noisier
than Norm A/C but more economical and efficient. This mode will
reduce undesirable odors from entering the vehicle.
•Norm A/C – Distributes outside air through the instrument panel
registers. The A/C compressor will only function if the outside
temperature is above approximately 2°C (36°F).
•Vent – Distributes outside air through the instrument panel registers.
The air cannot be cooled below the outside temperature.
•Off – Outside air is shut out and the fan will not operate. This mode
will reduce undesirable odors form entering the vehicle but may
increase the possibility of interior window fogging.

•Floor – Distributes outside air through the floor ducts. The air cannot
be cooled below the outside temperature.
•Mix – Distributes outside air through the floor ducts, the windshield
defroster ducts and the side window demisters. The A/C compressor
will operate automatically if the outside temperature is above
approximately 2°C (36°F). The air distributed through the floor ducts
will be slightly warmer than that sent to the windshield defroster
ducts and the side window demisters.
•
Defrost – Distributes outside air through the windshield defroster
ducts and the side window demisters. The A/C compressor will
operate automatically if the outside temperature is above
approximately 2°C (36°F). This mode will clear ice and fog from the
windshield.
Since the air conditioner removes moisture from the air, it is
considered normal operation if water drips on the ground under
the air conditioner drain.
Operating tips
•To reduce fogging under humid weather conditions, place the climate
control system in Defrost and Rear Defrost (if equipped) mode before
driving.
•To reduce humidity buildup inside the vehicle: Do not drive with the
climate control system in Off mode. Do not drive with the climate
control system in Max A/C mode (if equipped).
•Under normal weather conditions, do not leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
•Under snowy or dirty weather conditions, leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
•Remove any snow, ice or leaves from the exterior base of the
windshield.
•To increase the efficiency of the A/C (if equipped), drive with the
windows slightly open for 2–3 minutes or until the vehicle has been
“aired” out.
•Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.

To aid in side window defogging/demisting in cold weather conditions:
1. Select Vent.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.
ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
The EATC system will maintain a
selected temperature and
automatically control the fan speed
and airflow location.
Automatic operation
Press Automatic/AUTO and select the desired temperature. The system
will either heat or cool to achieve the selected temperature. The system
will automatically determine fan speed, airflow location and if outside air
or recirculated air is required.
When in automatic operation and weather conditions require heat, the
air will be sent to the floor ducts. However, until the engine has warmed,
the fan speed will operate at a low speed and airflow will be directed to
the windshield defroster ducts. Upon engine warm up, the system will
automatically direct airflow to the floor ducts and operate the required
fan speed to achieve the selected temperature.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
overrides allow you to select airflow locations and the fan speed. To
return to automatic operation, press Automatic/AUTO.

Temperature selection
To control the temperature, select
the desired temperature by pressing
the temperature controls.
For continuous maximum cooling,
push the temperature control until
16°C (60°F) is shown in the display
window. The system will continue
maximum cooling (disregarding the
displayed temperature) until a
warmer temperature is selected by
pressing the temperature control.
For continuous maximum heating,
push the temperature control until
32°C (90°F) appears in the display
window. The system will continue maximum heating (disregarding the
displayed temperature) until a cooler temperature is selected by pressing
the temperature control.
Temperature conversion
If your vehicle has an English/Metric
(E/M) control to change your
electronic cluster display (if
equipped) and the message center
display (if equipped) from English
to Metric, this control will also
change the temperature display.
Displaying outside temperature
Press Ext Temp/Outside Temp to display the outside temperature. The
outside temperature will be displayed until Ext Temp/Outside Temp has
been pressed again.
If the interior temperature or fan speed are adjusted or a manual
override is selected while the outside temperature is being displayed, the
new temperature, fan speed, or override control will appear in the
display window for four seconds and the outside temperature will return
to the display window.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be displayed when the vehicle is not

moving. Due to locations, the outside temperature readings displayed on
the climate control system may not agree with those from the radio
station broadcasts.
Fan speed (
)
When in automatic operation, fan
speed operates as necessary to
achieve the selected temperature. If
desired, the fan speed can be
controlled manually through the use
of the fan speed control. To return
to automatic fan operation, press
Automatic/AUTO.
Manual override controls
The manual override controls allow
you to determine airflow location
and fan speed. To return to full
automatic control, press
Automatic/AUTO.
•Max A/C - Distributes recirculated air through the instrument panel
registers. A temperature of 16°C (60°F) will appear in the display
window until Automatic/AUTO, another manual override control, or
the temperature control has been selected. The A/C compressor will
only function if the outside temperature is above approximately 2°C
(36°F). Max A/C is noisier than Norm A/C, but more economic and
efficient. This mode will reduce undesirable odors from entering the
vehicle.
•Norm A/C- Distributes outside air through the instrument panel
registers. The A/C compressor will only function if the outside
temperature is above approximately 2°C (36°F). Norm A/C is more
quiet than Max A/C, but not as economic and efficient.

The air cannot be cooled below the outside temperature.
