3-4
Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the lower mode, outside air will be brought in and
sent through the floor outlets. The heater works best if
you keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results, move the temperature knob to the
middle position, and then adjust it for comfort.
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
If your vehicle is equipped with an engine coolant heater
and you use it during cold weather, 0
F (
-18
C) or
lower, your heating system will provide heat more
quickly because the engine coolant is already warmed.
See ªEngine Coolant Heaterº in the Index.Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To rapidly defrost the windshield, turn the temperature
knob all the way clockwise (to the red area) and turn the
mode knob to defrost. Adjust the fan to the highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob to defog.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the bi
-level setting and adjust the fan to the highest
speed. Aim the side vents on the instrument panel
toward the side windows. For increased airflow to the
side vents, close the center vents.
Operating the HVAC system in the recirculation mode may
cause fogging of the vehicle's windows when the weather is
cold and damp. To clear the fog, switch the HVAC system to
either the defog or defrost mode and increase the fan speed.
To avoid re
-fogging of the windows, operate the HVAC
system in the outside air mode.
For additional information, refer to ªRecirculationº
earlier in this section.

3-5 Dual Automatic ComforTemp Climate
Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.
The vehicle's interior will warm up or cool down at the
same rate no matter which temperature you choose. For
example, if you set the system at 90
F (32
C) it will not
heat any faster than if you had set it at 70
F (21
C).
It will just continue to heat longer.Automatic Control
For the most efficient operation, you should set the
system temperature and push the driver's temperature
knob for automatic operation. The word AUTO will be
shown in the display. The system will select the best fan
speed and airflow settings to keep you comfortable.
The air conditioning compressor will run if the outside
temperature is above 32
F (0
C). You may notice a
delay of two to three minutes before the fan comes on
when you start your vehicle in cool weather.
Driver's Temperature Control
The driver's temperature knob sets the temperature for
the system when the passenger's temperature setting is
in neutral. If the passenger's temperature setting is not in
neutral, the driver's temperature knob sets the
temperature for the driver only.
Turn the knob clockwise to raise the temperature and
counterclockwise to lower the temperature. The display
will show the temperature briefly, then the outside
temperature will be displayed.
If you push the temperature knob for automatic
operation, the system will control the fan speed and
air temperature.

3-6
Passenger's Temperature Control
The passenger's temperature knob adjusts the
temperature on the passenger's side of the vehicle so
it is warmer or cooler than the temperature set by the
driver. The passenger temperature setting is shown
under the words PASS TEMP in the display.
Turn the knob clockwise to raise the temperature and
counterclockwise to lower the temperature. The display
will not show the passenger's temperature
-- only that
of the driver. Indicators under the words PASS TEMP in
the display will show passenger temperature relative
driver's set temperature.
The large single bar in the center of the + and
- symbols
(neutral) indicates the same temperature as the driver.
The bars between the center bar and the + symbol
indicate a warmer temperature setting than the driver.
The bars between the center bar and the
- symbol
indicate a cooler temperature setting than the driver.
Manual Control
You can also manually control the heating, cooling
and ventilation in your vehicle. You can select airflow
direction, fan speed, outside or recirculated air and air
compressor operation by using the following:Mode Button
This button has several settings to control direction of
airflow when the system is not in AUTO. To access the
various modes available, continue to press MODE until
the desired mode appears in the display.
(Defog): This setting directs half of the air to
the floor ducts and half to the defroster and side
window vents.
(Bi-Level): This setting directs half of the air
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and
a little to the defroster and side window vents.
(Upper): This setting directs air through the
instrument panel outlets.
(Lower): This setting brings in most of the air
through the floor ducts. The rest comes out of the
defroster and side window vents.
(Defrost): This setting brings in outside air and
directs most of the air through the defrost vent. Some of
the air also goes to the floor ducts and the side window
defogger outlets. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 32
F (0
C).

3-7
Mode Buttons
VENT: This button turns the air conditioning
compressor on and off and changes the mode to
upper. The words A/C OFF are shown in the display.
Recirculation is not permitted when the compressor
is off. The system will try to control the temperature
automatically, but without the compressor.
(Recirculation): Press this button
(the recirculation symbol in the display will be lit) to
recirculate the air inside of your vehicle and to limit the
amount of outside air and/or odors entering the vehicle.
Press this button again (the recirculation symbol will
go off) to send outside air into your vehicle. Using this
setting while trying to defrost or defog the windows will
help clear the vents of moisture. When the defog, defrost
or lower setting is selected, the system will
automatically go to outside air mode.
Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the recirculation mode may cause
fogging of the vehicle's windows when the weather
is cold and damp. To clear the fog, switch the HVAC
system to either the defog or defrost mode and increase
the fan speed. To avoid refogging of the windows,
operate the HVAC system in the outside air mode.Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature knob and fan speed as desired.
To get maximum cooling or a quick cool
-down on very
hot days, press the recirculation button (the recirculation
symbol in the display will be lit) and turn the
temperature knob to the desired interior temperature.
Then, select the mode to direct the air to the desired
location. This setting should not be used for long
periods of time because the air may become too cold
and dry.
Push the recirculation button again (the recirculation
symbol will go off) to turn off recirculation.
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.

Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, press the defrost button
and set the temperature to 90
F (32
C) and select a high
fan speed.
To warm passengers while keeping the window clear,
select the defog mode with the mode button (the defog
symbol will be lit). Select the fan speed for comfort and
windshield clearing performance.

3-9 Rear Window Defogger
Manual System
Automatic SystemPress the REAR button (the indicator light will glow) to
warm the defogger grid on the rear window. The engine
must be running for the defogger grid to warm up.
The system will turn off automatically after about
10 minutes of use. If you turn it on again, the defogger
will operate for about five minutes. You can also turn
the defogger off by turning the ignition to OFF or
by pressing the button again. The indicator light will
turn off.
If your vehicle has heated outside rearview mirrors,
the outside mirrors will also defrost when you press
this button.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

3-10 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
is running.
Your vehicle has air outlets that allow you to adjust
the direction and amount of airflow inside the vehicle.
Push the outlet up or down to direct the airflow.
Opening and closing the louvers will also direct airflow
from side to side.Ventilation Tips

Keep the hood and front air inlet free of ice, snow
or any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, select the
lower mode and set the fan to the highest setting for
a few moments before driving off. This helps clear
the intake ducts of snow and moisture, and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats and around
the base of the center console clear of objects.
This helps air to circulate throughout your vehicle.

If the airflow seems very low when the fan is
adjusted to the highest setting, your passenger
compartment air filter may need replacement.
See ªPassenger Compartment Air Filterº in the
Index for more information.

4-24
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Buick dealerships all across North America. They'll be
ready and willing to help if you need it.Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

4-31

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

4-32
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
-- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as ªdinghy towingº (towing your
vehicle with all four wheels on the ground) and ªdolly
towingº (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a ªdollyº).With the proper preparation and equipment, many
vehicles can be towed in these ways. See ªDinghy
Towingº and ªDolly Towing,º following.
Here are some important things to consider before you
do recreational vehicle towing:

What's the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer's recommendations.

How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.

Do you have the proper towing equipment? See your
dealer or trailering professional for additional advice
and equipment recommendations.

Is your vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you'll want to
make sure your vehicle is prepared to be towed. See
ªBefore Leaving on a Long Tripº in the Index.
