Hot Weather Example: When you start the vehicle in
hot weather, 80
_F (27_C), or after being parked during
the day in full sun, if your driver set temperature is 75
_F
(24
_C) and you are in full automatic mode, the system
will automatically move the temperature to full cold.
The fan will be at low speed momentarily and then go
to the high speed. The air intake will be recirculated for
maximum cooling performance. As the interior of the
vehicle cools down to your desired comfort point, the fan
speed will decrease and the temperature will move to a
warmer position to maintain your desired comfort. As the
interior cools down or the sun load decreases the system
could switch to air delivered to A/C vents and the floor.
Cold Weather Example: When you start the vehicle in
cold weather, (below freezing) or after being parked
overnight. If your Driver Set Temperature is 75
_F (24_C)
and you are in Full Automatic mode, the system will
automatically move the temperature doors to full hot. The fan
will start out at a low speed and will increase to a higher
speed as the engine warms up. The air will be delivered to
the floor. As the the interior of the vehicle warms up to your
desired comfort point, the fan speed will decrease and the
temperature will move to a cooler position to maintain your
desired comfort. As the cabin warms up or the sun load
increases the system could switch to air delivered to the
windshield and the floor (DEFOG mode).
Manual Control
If you prefer to manually control the heating, cooling and
ventilation in your vehicle, you can select airflow direction,
fan speed, outside or recirculated air, air compressor and

the AIR FLOW rocker button up or down until the
desired mode appears in the display:
D WINDSHIELD/FLOOR: This setting directs half

compressor will run automatically in this setting
unless the outside temperature is below 40
_F (4_C).
D MID/FLOOR: This setting directs half of the air
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and
a little to the defroster and side window vents.
