D. Air distribution control: Press to set the air distribution to a
position listed below:
Distributes air through the windshield defroster vents, demister
vents and floor vents.
Distributes air through the instrument panel vents.
Distributes air through the instrument panel vents and floor
vents.
Distributes air through the floor vents.
E. A/C: Press to turn air conditioning off and on. Air conditioning cools the
vehicle using outside air. To improve air conditioning when starting your
vehicle, drive with the windows slightly open for two to three minutes.
Use A/C with recirculated air to improve cooling performance and efficiency.
Note: A/C turns on automatically in MAX A/C, Defrost and Floor/Defrost.
F. MAX A/C: Distributes recirculated air through the instrument panel
vents to cool the vehicle. This position is more economical and efficient
than normal A/C.
G. Recirculated air: Press to switch between outside air and
recirculated air. When the LED on the button is lit, the air currently in
the passenger compartment is being recirculated. Using recirculated air
can reduce the time needed to cool the interior and reduce unwanted
odors from entering your vehicle. Even when this button is not selected,
air may still recirculate in some instances in order to reduce vehicle
warm-up time in cold conditions or to cool down time in hot conditions.
Note: Recirculated air engages automatically when MAX A/C is selected
or can be turned on manually in any airflow mode except Defrost.
Note: You may notice changes in sound between recirculated mode and
other airflow modes.
Note: For better cooling in hot conditions, recirculated air automatically
engages when the air distribution control is in panel or panel/floor modes
and the air conditioning is on. You can switch to fresh air by pressing the
recirculated air button again.
H. PASS TEMP: Press to switch between single and dual zone. Turn to
increase or decrease the air temperature on the passenger side of the
vehicle.
