FRONT (Defrost): This setting brings in outside air
and directs most of the air through the defrost outlet.
Some of the air also goes to the floor vents and the side
window outlets. The indicator light on the button will
come on and WINDSHIELD will be seen on the display
To defrost the windows quickly, press the FRONT
button, set the temperature to 90°F (32"C), select a high
fan speed an turn the DUAL button off.
To warm passengers while keeping the window clear,
push the AIR FLOW button and WINDSHIELD/FLOOR
will appear on the display. Select a fan speed.
The air-conditioning compressor will run automatically
in this setting unless the outside temperature is
below 40°F (4°C).
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
@
REAR: Press this button to turn the rear window
defogger on. It will turn off after about 15 minutes. If you
turn it on again, the rear defogger will only run for
about seven and one half minutes before turning off.
You can also turn it off by pressing the button again.
Notice: Don't use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
