Circulation Control
Press the mode control knob
to activate the recirculation
mode. A lamp (in the knob)
will illuminate when you are
in recirculate mode. Press the
knob again to deactivate the
system. Only use the recircu-
lation 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: 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 recirculation
mode will cause windows to fog on the inside because of
moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
NOTE: Recirculation mode will not operate in floor, mix
or defrost modes.
Air Conditioning Operation
Press the temperature control
knob to activate the air condi-
tioning mode. A lamp will
illuminate when the Air Con-
ditioning System is engaged.
Press the knob again to deac-
tivate the system.
NOTE: The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.
