When the indicator in the button is
on, air from the vehicle’s interior is
sent through the system again.
When the indicator is off, air is
brought in from the outside of the
vehicle (fresh air mode).
The outside air intakes for the
climate control system are at the
base of the windshield. Keep this
area clear of leaves and other debris.
The system should be left in fresh
air mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.
Switch to recirculation mode when
driving through dusty or smoky
conditions, then return to fresh air
mode.
This button turns the windshield
defrost on and off.
When you push this button, air flows
from the defroster vents at the base
of the windshield, and the system
automatically switches to fresh air
mode and turns on the A/C. When
the indicator in the button is on, the
passenger’s temperature cannot be
set separately from the driver’s.
This button turns the rear window
defogger on and off. Pushing this
button also turns the mirror heaters
on and off (see page
