Ventilation Tips
0
Keep
the
hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.
0
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
0
When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow
air that is too cool. Once the vehicle
is
moving again,
the system will try
to
maintain the set temperature
inside your vehicle.

When you start your vehicle and the
EXT
display
flashes (Dual Automatic Comfortemp system only)
for some time, the system may need repair. See your
Buick dealer.
Defogging and Defrosting
If you have the electronic touch system, adjust the
TENPERATURE lever toward WARM and the FAN
lever toward HIGH.
If you have the Dual Automatic Comfortemp system,
use the FRONT button to defog or defrost the
windshield. By choosing this button, the airflow will be
directed at the windshield. Adjust your comfort level by
pressing the TEMP up or down arrow. The fan speed
will be controlled by the system. You can change the fan
speed by pressing the top of the FAN button to increase
speed, and the bottom of the button to decrease speed.
