Front Blower Control
The front blower controls the
amount of air delivered to the
passenger
compartment.
There are four blower speeds.
The fan speed increases as
you turn the control clock-
wise. When the front blower
control is turned to OFF, the
blower will be turned off and
the system will be positioned
in recirculation mode.
Front Mode Control
The mode control allows you to
choose from several patterns of air
distribution.
NOTE: To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots and give an even blend of both
modes.
