Buick 1994 LeSabre Owner's Manual page 125

Auto
AUTO is used when
you
want the system to adjust
automatically to changes in
temperature. When the
system is set for automatic,
air will come from the floor
outlets, the instrument
panel outlets, or windshield
outlets.
Fan speed will vary (unless a blower LO or
HI
button
has been pushed) as the system gets to and maintains the
temperature setting you have selected.
To find your comfort zone, start with 75 AUTO, give the
car about 20 minutes to stabilize and adjust the
temperature setting if necessary. The display
will
show
the set temperature and fan speed.
In cold weather the system will delay turning on the fan,
to avoid blowing cold air. The length of the delay
depends on engine coolant temperature, outside
temperature, and time since the engine was last started.
Pushing a LO or HI
blower button will override this
delay, and cause the fan to start.
To rid the system of stale air in warm weather, air will
come out of the floor outlets for
a
short time.
Dual Zone
- '
.
The front seat passenger
can control air temperature
in that seating area. This
control can be up to
5
O F
cooler or warmer than the
primary setting.
The control is on the passenger's door. Both DUAL
ZONE and AUTO buttons will light up.
