Outlet Adjustment; Rear Climate Control System - Cadillac DTS 2011 Owner's Manual

In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
Vehicle speed is above 51 km/h (32 mph) for 2 and
a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the
air delivery mode. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.

Outlet Adjustment

For the front outlets, use the thumbwheel located below
each outlet to change the direction of the airflow. Use
the thumbwheel located next to the outlets to shut the
airflow or to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up or
down to change the direction of the airflow.

Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into your vehicle.
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.

Rear Climate Control System

For vehicles with a rear climate control system, the rear
seat passengers can adjust the direction of the airflow,
fan speed and temperature for the rear seating area.
This system also works with the main climate control
system in the vehicle.
