Cadillac 2008 STS Automobile User Manual


 
The right knob controls the air delivery to the rear
passengers. Turning the knob all the way to the left will
shut off airflow to the rear passengers. Operating with
the rear air delivery off may make the entire vehicle
warm or cool less quickly. It may also increase the air
rush sound of the front system.
9(Off): This is the off position.
Y (Vent): This mode directs all the rear passenger
airflow to the outlets in the console. This is the
normal position for cool down conditions.
\(Bi-Level): This mode directs airflow to the
console outlets and the floor.
[(Floor): This mode directs all of the airflow to the
floor. This is the normal position for warm up conditions.
The amount of airflow to the rear passengers is
controlled automatically by the front climate control
system, regardless of optional equipment. Airflow to
the rear system will be turned off when defrost is
selected on the front climate control panel to direct
air to clear the windshield.
Vehicles equipped with a rear climate control panel,
also, have heated rear seats. There are two buttons,
each with three indicator lights, located between the
two climate control knobs on the rear climate control
panel, to control the rear heated seats. See Heated
Seats on page 1-7 for additional information.
Be sure to keep the area under the front seats clear
of any objects so the air in your vehicle can circulate
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air filter. There are two types of filters
available. There is a standard dust filter that traps small
particles including pollen. There is, also, a dust/odor
filter available that traps dust and pollen and also uses
a charcoal element to help reduce many offensive
odors from entering your vehicle. The filter will need
to be changed periodically. For information on how
often to change the passenger compartment air filter,
see Scheduled Maintenance on page 6-4.
Notice: Driving without a passenger compartment
air filter in place can cause water and small particles,
like paper and leaves, to be pulled into your climate
control system which may cause damage to it. Make
sure you always replace the old filter with a new one.
