2008 CADILLAC STS Driver side window

AUTO (Automatic):When this button is pressed and
the temperature is set, the system automatically controls
the inside temperature, the air delivery mode, the air
conditioning compressor, and the fan speed. AUTO will
appear on the display next to the fan, mode indicators,
and recirculation indicator if the vehicle has a air
quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If the system is set at the warmest temperature
setting, the system will try to continuously heat the
vehicle and will not adjust the system down as the
vehicle warms up.
In cold weather, the system can start at reduced
fan speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system starts
out blowing air at the oor, but can automatically
change modes as the vehicle warms up to maintain
the chosen temperature setting. The length of
time needed for warm up depends on the outside
temperature and the length of time that has elapsed
since the vehicle was last driven.
3. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the temperature,
if necessary.You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Operation
and Displays on page 3-74.
The air-conditioning system removes moisture from the
air, so some water might drip underneath the vehicle
while idling or after turning off the engine. This is normal.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
allows the operator to manually select the air delivery
location. Press AUTO to return to automatic operation.
The outboard air outlets always receive airow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-54to change this airow from the outboard
outlets.
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode splits the air between
the instrument panel outlets and the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.

Under some conditions, the air quality sensor system
does not operate. In cold weather, the system might
not be active (even if AUTO is displayed) because
of concerns of fogging your windows, which may occur
by activating recirculation mode. Also, the air quality
sensor system does not remain in recirculation mode
for extended periods of time that could cause stuffy
or very dry conditions in the vehicle. Following a poorly
running vehicle for an extended period of time may
not keep recirculation active indenitely.
The air quality sensor does not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types
of odors, manually select recirculation. Your vehicle
could also have a charcoal lter that can limit many
odors from being pulled into your vehicle. This
lter needs to be changed periodically. SeeScheduled
Maintenance on page 6-4. The air quality sensor
system does not protect against carbon monoxide (CO),
which you cannot see or smell. SeeEngine Exhaust
on page 2-38.
O(Power Driver’s Temperature):Press the power
button located on the driver’s side of the climate
control panel to turn the entire climate control system
on or off. Turn the knob to increase or decrease
the temperature inside the vehicle.
O(Power Passenger’s Temperature):Press the
power button located on the passenger’s side of
the climate control panel to turn the passenger’s climate
control system on if they wish to have a different
setting than the driver. Turn the knob to increase or
decrease the temperature for the front passenger.
Turning the passenger’s side power button off will not
shut off the climate control system for the passenger.
The system is set to the same setting as the driver.
{(Ventilated Seat):Press this button, to turn
on the driver or passenger’s side ventilated seat,
if the vehicle has this feature. SeeHeated and
Ventilated Seats on page 1-3.
J(Heated Seat):Press this button, to turn on the
driver or passenger’s side heated seat and seatback,
if the vehicle has this feature. SeeHeated and
Ventilated Seats on page 1-3.
^(Air Conditioning):Press this button to manually
turn off the air conditioning compressor. Press AUTO
to return to automatic operation. To limit fogging on
the windshield, the air conditioning compressor
cannot be off while in the defrost mode.
