Introduction

•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 HI
4. Direct the outer panel vents towards to side windows
To increase airflow to the outer panel vents, close the central panel
vents.
