Defrost Mode

Air is directed through the windshield and side
window demist outlets. Use DEFROST mode with

maximum blower and temperature settings for best
windshield and side window defrosting.

NOTE:

The air conditioning compressor operates in

MIX and DEFROST, or a blend of these modes even if the
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.

Recirculation Control

Press this button to choose between outside air
intake or recirculation of the air inside the
vehicle. A lamp will illuminate when you are in
RECIRCULATION mode. Only use the RECIR-

CULATION mode to temporarily block out any outside
odors, smoke, or dust, and to cool the interior rapidly
upon initial start-up in very hot or humid weather.

NOTE:

• If the RECIRCULATION button is pressed when the

system is in MIX, DEFROST, or FLOOR mode the
RECIRCULATION LED indicator will flash 3 times
and then turn off to indicate RECIRCULATION mode
is not allowed.

• Continuous use of the RECIRCULATION mode may

make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.

• In cold or damp weather, the use of the RECIRCULA-

TION mode will cause windows to fog on the inside
because of moisture buildup inside the vehicle. For
maximum defogging, select the outside air position.

• In order to prevent fogging, when the RECIRCULA-

TION button is pressed and the mode control is set to
PANEL, the A/C will engage automatically.
