Defogging and Defrosting
On cool, humid days, use DEFOG (digital cluster

or ice from the windshield quickly in extremely humid
or cold conditions.
With the digital cluster climate control panel, press
the DEFOG button and adjust the fan speed by pressing
the fan button up or down. If you use DEFROST,
adjust the fan speed the same way.
If you select
DEFROST from AUTO, the system will control the
fan speed. The temperature will also need to be
adjusted to your comfort level. Press the blue button
to decrease the temperature and the red button
to
increase the temperature.
If your vehicle has a climate control panel (which is
standard with the analog cluster). If you select
DEFROST, adjust the fan speed by pressing the fan
button up or down. If you select DEFROST from
AUTO, the system will control the fan speed. The
temperature also needs to be adjusted by turning the
TEMP/AUTO knob.
Note that recirculation is not available in the defiost
or defog modes.
