8-4 Climate Controls
(Outside Air): Press to turn
on outside air. An indicator light
comes on to show that it is on.
Outside air will circulate throughout
the vehicle.
(Recirculation): Press to
turn on the recirculation mode. An
indicator light comes on to show
that it is on.
This mode helps to quickly heat or
cool the air inside the vehicle once
the temperature inside the vehicle is
equal to or better than the outside
temperature. It can be used to
prevent outside air and odors from
entering the vehicle. The
recirculation mode is not available in
outside air, floor, defog, or defrost
modes. If the button is selected
while in these modes, the indicator
flashes three times.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.

(Rear Window Defogger): The
rear window defogger turns off
automatically after it has been
activated for 10 minutes. It can be
turned off manually, by pressing the
button again or by turning the
ignition to the LOCK/OFF position.
The rear window defogger can be
turned on again for additional
window clearing. The length of
defogger operation will increase if
the vehicle is being driven.
I n f o r ma t i o n P r o v i d e d b y :
For vehicles with heated outside
rearview mirrors, the mirrors heat to
help clear fog or frost from the
surface of the mirror when the rear
window defog button is pressed.
See Power Mirrors on page 2 13.
Do not drive the vehicle until all the
windows are clear.
Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal, or anything
similar to the defogger grid.
