Switching Maximum Defrost On
and Off
Press and release the button for
maximum defrosting.
The left-hand and right-hand settings set
to HI, air flows through the windshield air
vents, and the blower motor adjusts to the
highest speed.
You can also use this setting to defog and
clear the windshield of a thin covering of
ice.
Note: To prevent window fogging, you
cannot select recirculated air when
maximum defrost is on.
Note: The heated rear window also turns
on when you select maximum defrost.
Switching Recirculated Air On and
Off Press and release the button to
switch between outside air and
recirculated air.
The air currently in the passenger
compartment recirculates. This may
reduce the time needed to cool the interior,
when used with A/C, and reduce unwanted
odors from entering your vehicle.
Note: Recirculated air may turn off, or
prevent you from switching it on, in all air
flow modes except MAX A/C to reduce the
risk of fogging. Recirculation may also turn
on and off in various air distribution control
combinations during hot weather in order
to improve cooling efficiency.
HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Note: Prolonged use of recirculated air may
cause the windows to fog up. Note:
You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.
Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Manual Climate Control
Note: To reduce fogging of the windshield
during humid weather, adjust the air
distribution control to the windshield air
vents position.
Automatic Climate Control
Note: Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary. The system automatically
adjusts to heat or cool the interior to your
selected temperature as quickly as possible.
For the system to function efficiently, the
instrument panel and side air vents should
be fully open.
Note: If you select
AUTO during cold
temperatures, the system directs airflow to
the windshield and side window vents. In
addition, the fan may run at a slower speed
until the engine warms up.
Note: If you select
AUTO during hot
temperatures and the inside of the vehicle
is hot, the system automatically uses
recirculated air to maximize interior cooling.
Fan speed may also reduce until the air
cools.
