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.
When you enter a vehicle with the electronic touch
system in cold weather, select HTR to supply air
through the floor outlets. Then move the FAN lever
to HIGH for a few moments before driving away.
This will blow moist air from the intake outlets
toward the floor, not the windshield. It reduces the
chance of fogging your windows. If you have the
dual automatic comfortemp system, the AUTO
setting will do this for you. Manual operation of the
automatic comfortemp system in the
FLOOR mode
will also supply air through the floor outlets.
Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
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.
0 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
On cool but humid days, use FRONT to keep the
windshield and side windows clear and to quickly
remove fog, frost or ice from the windshield.
If you have the the electronic touch system, adjust the
TEMPERATURE lever toward
WARM and the FAN
lever toward HIGH.
If you have the dual automatic cornfortemp system,
while in the AUTO mode, the fan speed will vary.
If a
manual fan speed setting
is selected, the fan speed will
remain at that selection until the engine is turned
off or
another selection has been made. To turn off FRONT,
press
AUTO or AIR FLOW.
