Cadillac 2007 STS Automobile User Manual


 
AUTO (Automatic): When this button is pressed
and the temperature is set, the system will
automatically control 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 your 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 Controls and Displays on page 258.
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.
