An indicator light to the right of the button will
come on to show that the recirculation button has
been pressed. The instrument panel brightness
control may have to be adjusted to the highest
setting to see the indicator.
The recirculation mode has a timer. After
five minutes, the system's air inlet door will move
slightly to allow for ten percent fresh outside
air to maintain interior air quality. The only way to
reset the system to full recirculation is to restart
the five minute timer by selecting vent/outside air
and recirculation again.
Rear Window Defogger
The rear window defogger uses a warming grid
to remove fog or frost from the rear window.
Be sure to clear as much snow from the rear
window as possible.
Notice: Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
