Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
6014443) - 2014 - CRC - 4/3/13
Climate Controls 8-5
When the ignition is turned to ON/
RUN, the climate control system
returns to the settings used before
the vehicle was last turned off. The
heated seats will turn off,
if equipped.
Sensors
The solar sensor on the instrument
panel, near the windshield, monitors
the solar heat.
The interior temperature sensor, on
the instrument panel to the right of
the steering wheel, measures the
temperature of the air inside the
vehicle.
The climate control system uses the
information from these sensors to
adjust the fan speed and the air
delivery, in order to maintain the
selected temperature. The system
may also supply cooler air to the
side of the vehicle facing the sun.
The recirculation mode will also be
activated, as necessary.
Do not cover the sensors or the
automatic climate control system will
not work properly.
Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate, such
as during cold weather or with
extreme odors. Press
M to
activate recirculation.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust on
page 9-25.
