Defrosting and Defogging
Use defrost (front) on cool and humid days to keep
the windshield and side windows clear. This setting will
remove fog or ice from the windshield quickly in
extremely humid or cold conditions. If you desire to
have more air on your feet, turn the control to the defog
mode. You may do this by pressing the right or left
arrow on the MODE button.
Press the up or down arrow on the fan button to control
the blower speed. You may also adjust the temperature
by turning the TEMP knob.
The recirculation mode and the A/C OFF message are
not available in the defrost mode.
Rear Window Defogger
The grid lines you see on
the rear window warm the
glass. Press this button to
turn on the rear defogger.
With it, the rear window and both outside rearview
mirrors are heated. The light on the button will come
on while the system is activated.
The system will automatically shut off after 10 minutes.
If further defogging is desired, press the button again.
The system will automatically shut off after five minutes
for any cycles after the initial activation.
Note: The lines along the top of the window are for
the diversity antenna and are not intended to defog the
rear window.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Scraping the inside of your rear window could
cut and damage the heating grids. Your warranty
would not cover this damage. Don’t put decals
there because you might have to scrape them off.
