• Defrost
Air is directed through the windshield and
side window demister outlets. Use this mode
with maximum blower and temperature settings for
best windshield and side window defrosting.
NOTE: The air conditioning compressor operates in Mix
or Defrost, even if the Air Conditioning (A/C) button is
not pressed. This dehumidifies the air to help dry the
windshield. To improve fuel economy, use these modes
only when necessary.
6. Blower Control
Rotate this control to regulate the amount of air forced
through the ventilation system in any mode. The blower
speed increases as you move the control to the right from
the “0” (OFF) position. There are four blower speeds.
Rear Window/Mirror Defrosting
Push, and release the rear window defrost button to turn
the function on/off.
The activation of the rear defroster is indicated by the
rear defrost warning light on the instrument panel. The
function is automatically deactivated after 20 minutes.
If equipped, push the rear defrost button to activate
defrosting of door mirrors and heated rear window.
NOTE:
Do not affix stickers to the inside of the heated
rear window over the heating filaments, to avoid damage
that might cause them to stop working properly.
