use it to help your system provide warm air faster

Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows.
For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, rotate the
temperature control knob all the way in the red area.
Use DEFROST and adjust the fan to the highest speed.
To warrn passengers while keeping the front window
clean, use DEFOG.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located
on the outside of the side instrument panel vents. To
defrost the side windows rotate the temperature control
knob all the way in the red area. Use
FLOOR and adjust
the fan to the highest speed. To control fogging of the
windows rotate the temperature control knob all the
way in the red area. Use DEFOG and adjust the fan
to the highest speed.
To defog the side windows while using air conditioning
use BI-LEVEL and adjust the fan to the highest speed and press the
A/C button. For added airflow to the side
windows aim the side vents toward the windows and
close the center vents.
RECIRCULATION will not work in DEFROST and
DEFOG. This is done to prevent recirculation of humid
inside air and allow the system to work properly.
