Cadillac 2008 STS-V Automobile User Manual


 
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 floor, 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). See DIC 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
yN z(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 airflow
regardless of the mode selected. See Outlet Adjustment
on page 3-54 to change this airflow 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 floor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the floor outlets.
[(Floor): This mode directs most of the air to the
floor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.
