8-8 Climate Controls
@ (Recirculation): Press to turn
the recirculation mode on or off. An
indicator light comes on to show
that the recirculation is on.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors from
entering the vehicle.
The recirculation mode cannot
be used with floor, defog, or
defrost modes. If recirculation
is selected with one of those
modes, the indicator light flashes
three times and then turns off. The
air conditioning compressor also
comes on when this mode is
activated. While in recirculation
mode the windows may fog when
the weather is cold and damp.
To clear the fog, select either the
defog or defrost mode and increase
the fan speed.
The recirculation mode can also be
turned off by turning off the ignition.

heat and air conditioning controls.

system on or off. See Rear Climate
Control System (Rear Climate

Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
< (Rear Window Defogger):
Press to turn the rear window
defogger on or off. It automatically
turns off several minutes after it has

Notice: Do not use a razor blade
