Buick 2007 Automobile User Manual


 
# (Air Conditioning): Press this button to turn
the air conditioning system on or off. When this
button is pressed, an indicator light below the
button will come on to let you know the air
conditioning is activated. Air conditioning can
be selected in any mode as long as the fan knob
is not in the off position.
On hot days during the vehicle’s initial start-up,
open the windows to let hot inside air escape; then
close them. This helps to reduce the time it takes
for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quicker cool down on hot days, do the
following:
1. Select the vent air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air-conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath your
vehicle while idling or after turning off the
engine. This is normal.
Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are two
modes to clear frost or fog from the windshield.
Use the floor/defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
Turn the right knob to select the defog or defrost
mode. The recirculation mode cannot be selected
while in these modes.
- (Floor/Defog): This mode directs half of the air
to the windshield and the side window outlets and
half to the floor outlets. The system runs the air
conditioning compressor unless the outside
temperature is near or below freezing.
0 (Defrost): This mode directs most of the air to
the windshield and the side window outlets. The
system runs the air conditioning compressor unless
the outside temperature is near or below freezing.
