Tempmerature Button The TEMP button changes the temperature of the air coming through the system. Press the up arrow for warmer air-and the down arrow for cooler air. remain at that maximum heating setting and will not regulate the fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster. Pressing the AUTO button will display the requested temperature, fan speed and air delivery mode for five seconds, then change to display the outside air temperature. Be careful not to put anything over the sensor located in the middle of the instrument panel near the windshield, or over the sensor in the grille above the radio. These sensors are used by the automatic system to regulate temperature. The exterior temperature display sensor is in front of the car, near the radiator. This displayed temperature is most accurate when the vehicle is moving. During stops, or while idling, the display shows the previous dsaving temperature for best system control. To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on outside air temperature, engine coolant temperature, and time since the engine was last started. Pushing the fan button will override this delay and change the fan to a selected single speed. If you leave your vehicle, the system will remember the Mode Button Press this button to deliver air through the floor, middle or windshiel'd outlets. The system will stay inthe selected mode until the MODE or AUTO button is pushed. Press the up arrow to cycle through the available modes. Automatic Operation When the system is set for AUTO, sensors will control the air delivery mode. Air will come from the floor, middle and windshield outlets. The fan speed will vary as the system maintains the selected temperature setting. To find your comfort zone, start with 75 F (24" C) temperature setting and allow about 20 minutes for the system to regulate. Press the TEMP button up or down to adjust the temperature setting if necessary. If you choose the temperature setting of 60°F (15O C), the system will remain at that maximum cooling setting and will not regulate the fan speed. If you choose the the temperature setting of 90°F (33 "C), system will O control setting the next time you start your engine. 3-4

Tempmerature
Button
The
TEMP
button changes the temperature
of
the air
coming
through
the system. Press the
up
arrow
for
warmer air-and the down arrow for cooler air.
Mode
Button
Press this button to deliver
air
through the floor, middle
or windshiel'd outlets. The system will
stay
in
the
selected mode until the
MODE
or
AUTO
button
is
pushed. Press the
up
arrow
to
cycle through the
available
modes.
Automatic
Operation
When the system is set for AUTO, sensors will control
the air delivery mode.
Air will come from the floor,
middle and windshield outlets. The fan speed will vary
as the system maintains the selected temperature setting.
To
find your comfort zone, start with
75
O
F
(24"
C)
temperature setting and allow about
20
minutes for the
system to regulate. Press the TEMP button up or down
to
adjust the temperature setting if necessary.
If
you
choose the temperature setting
of
60°F
(15
O
C),
the
system
will
remain
at
that
maximum
cooling setting
and
will
not
regulate the fan speed.
If
you choose the
temperature setting
of
90°F
(33
"C),
the system will
remain at that maximum heating setting and will not
regulate the
fan
speed. Choosing either maximum
setting will not cause the system to heat or cool
any
faster.
Pressing the
AUTO
button will display the requested
temperature, fan speed and
air
delivery mode
for
five
seconds, then change to display the outside
air
temperature. Be careful not
to
put anything over the
sensor located in the middle of the instrument panel near
the windshield, or over the sensor in the grille above the
radio. These sensors are used
by the automatic system to
regulate temperature.
The exterior temperature display sensor is in front
of
the
car,
near the radiator. This displayed temperature
is
most
accurate when the vehicle is moving. During
stops,
or
while idling, the display shows the previous dsaving
temperature
for
best system control.
To
avoid blowing cold
air
in
cold weather, the system
will delay turning on the fan until warm air
is
available.
The length
of
delay depends
on
outside air temperature,
engine coolant temperature,
and
time since
the
engine
was last started. Pushing the
fan
button will override this
delay
and
change
the
fan
to
a
selected single
speed.
If
you
leave your vehicle, the system will remember the
control setting the next time you start your engine.
