Buick LaCrosse: Manual Operation
(Power): Press to turn the fan
off
or on.
(Fan Control): Press to
increase or decrease the fan speed.
The fan speed setting appears on the main display. Pressing either button cancels automatic fan control and the fan is controlled manually.
Press AUTO to return to automatic operation.
(Air Delivery Mode
Control): Press to change the
direction of the airflow. The current
mode appears in the display screen.
Pressing either button cancels automatic air delivery control and the direction of the airflow is controlled manually. Press AUTO to return to automatic operation.
To change the current mode, select one of the following:
(Vent): Air is directed to the
instrument panel outlets.
(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
(Tri-Level): Air is divided
between the windshield, instrument
panel, and floor outlets.
(Floor): Air is directed to the
floor outlets.
(Defog): Clears the windows of
fog or moisture. Air is directed to the
windshield and floor outlets.
(Defrost): Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and ice from the windshield before defrosting.
For eAssist vehicles that have the auto defog feature, auto stops can occur in defrost mode. In this mode, the auto stops are shorter and less frequent than other air delivery modes to prevent instant fogging.
(Comfort Air Conditioning):
Press to turn the air conditioning system on or off. If the climate control system is turned off or the outside temperature falls below freezing, the air conditioner will not run.
Pressing this button cancels automatic air conditioning and turns off the air conditioner. Press AUTO to return to automatic operation and the air conditioner runs automatically as needed. When the indicator light is on, the air conditioner runs automatically to cool the air inside the vehicle or to dry the air needed to defog the windshield faster.
For eAssist vehicles, an auto stop may occur if the climate control system determines the a/c compressor can be shut off and still maintain comfort levels with minimal windshield fogging.
Eco (Eco Air Conditioning, If
Equipped): This setting balances
fuel economy and air conditioning
comfort. In warm weather
conditions, auto stops may occur
more frequently and the vehicle
interior may be warmer as
compared to the comfort air
conditioning. The eco a/c setting
allows higher humidity inside the
vehicle and window fogging before
the engine restarts.
Pressing the button during an
auto stop will restart the engine to
prevent window fogging. To reach
comfort levels quickly during an
auto stop, the engine will restart if
the air conditioner is off and the
AUTO, eco
, or Comfort
is
selected. The engine also restarts if
the
is pressed on and the system
is set to AUTO, eco
,
or Comfort
.
If temperature controls are adjusted cooler by more than 1°C (1°F) during an auto stop, the engine will restart to ensure that comfort is reached.
(Recirculation/Auto
Recirculation): Press to change to
automatic control of air recirculation
inside the vehicle. When the auto
recirculation indicator light is on, the
air is automatically recirculated as
needed to help quickly cool the air
inside the vehicle.
In auto recirculation control, the Air Quality Control system may operate when pollution is detected. To adjust the sensitivity of the Air Quality Control, see “Climate and Air Quality” under Vehicle Personalization.
When the indicator light is on, air
is recirculated inside the vehicle.
If both indicator lights are off, outside air will flow into the vehicle.
Press AUTO or to return to
automatic operation.
Auto Defog: The climate control system may have a sensor to automatically detect high humidity inside the vehicle. When high humidity is detected, the climate control system may adjust to outside air supply and turn on the air conditioner. The fan speed may slightly increase to help prevent fogging. If the climate control system does not detect possible window fogging, it returns to normal operation. To turn Auto Defog off or on, see “Climate and Air Quality” under Vehicle Personalization.
