7-6 Climate Controls
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
recirculation, such as during cold
weather or with odors, like skunk.
To limit odors manually, press
M
until the condition has passed.
The air quality sensor system
does not protect against carbon
monoxide (CO), which you cannot
see or smell. See Engine Exhaust
on page 8‑26.
Air Vents
Use the air outlets located in
the center and on the side of the
instrument panel to direct the
airflow. Use the thumbwheels near
the air outlets to open or close off
the airflow.
Operation Tips
.
Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.
Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.
Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
