Defogging and Defrosting
There are two modes to clear fog or frost from your
windshield. Press the defog button to clear the windows
of fog or moisture and warm the passengers. Press
the defrost button to remove fog or frost from the
windshield more quickly.
/
(Defog): Press this button to direct the air equally
between the windshield and the floor outlets. When you
select this mode, the system turns off recirculation and
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
0
(Defrost): Press this button to direct most of
the air to the windshield and the side window outlets,
with some air directed to the floor outlets. In this mode,
the system will automatically turn off recirculation
and run the air-conditioning compressor, unless
the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
Outlet Adjustment
The air outlets are located in the center and on the
sides of your instrument panel. See Instrument Panel
Overview on page 3-4. You can move the vents to direct
the flow of air or close the outlets altogether. When
you close a vent, it will increase the flow of air coming
out of any vents that are open.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
The passenger compartment outside air is routed
through a passenger compartment filter. The filter
removes certain debris, including dirt and leaves.
Reductions in your climate control system performance
may indicate that the filter needs to be inspected and
cleaned.
The passenger compartment air filter can be accessed
from the outside of the vehicle on the front passenger
side. It is concealed by the front access panel. Pull the
latch inside the cab on the driver’s side of the vehicle
to open the front panel.
