Ashtrays and Lighter
The center front ashtray is located just below the
instrument panel’s comfort controls at the front
of the
console.
To remove the ashtray, open the front
compartment storage door. Then open the small black
door, lift up on the ashtray and pull it out.
The rear ashtray is located within a small door at the rear
of the console. Push on the right side of the door. The
ashtray will then rotate to the right for usage. You can
only access the ashtray by pushing on the door’s right
side.
To remove the ashtray, push down on the snuffer
located in the middle
of the ashtray and lift it out.
NOTICE:
Don’t put papers and other things that burn
into your ashtrays.
If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
To use the lighter, just push it in all the way and let go.
When it’s ready, it will
pop back by itself.
NOTICE:
Don’t hold a cigarette lighter in with your hand
while it is heating.
If you do, it won’t be able to
back away from the heating element when it’s
ready. That can make it overheat, damaging the
lighter and the heating element.

Engine Coolant Temperature Light
h -
TEMP
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
The light will come
on
briefly when your ignition
is turned on to show you
that it is working.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.
Engine Coolant Temperature Gage
.. 1. TEMP
You have a gage that
shows the engine coolant
temperature. If the gage
pointer moves into the red area, your engine is too hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated.
If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Comfort Controls
Manual Single Zone Climate Control
COMFORT CONTROL II
With this system, you can control the heating, cooling
and ventilation in your vehicle, The system works best if
you keep your windows closed while using it.
Fan Knob
The left knob selects the amount of air you want. To turn
the fan off, turn the knob to
OFF.
If the airflow seems very low when the fan knob is turned
to
the highest setting, regardless of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule”
in the Index.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow:
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument panel
outlets. The air conditioning compressor will run
automatically
in this setting unless the outside
temperature is below
40°F (4°C). (Even when the
compressor is running,
you can control the temperature.)
NORM: This setting brings in outside air and sends
it through the instrument panel outlets. The air
conditioning compressor will run automatically in
this setting unless the outside temperature
is below
40°F (4°C). (Even when the compressor is running,
you can control the temperature.)

Heating
On cold days, use HTR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat
it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (- 18 O C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
flow-through ventilation system described later in
this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, use
FRONT with the temperature knob all the way in the red
area.
To warm passengers while keeping the windows
clear, use
BLEND.
Dual ComforTemp Climate Control
(If Equipped)
I_ .
With this system, the driver and passenger can maintain
separate temperatures. The system works best if you
keep your windows closed while using it.
Fan Control
The left knob labeled FAN controls the fan speed selection.
If the airflow seems very low when the fan knob is turned
to the highest setting regardless
of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule’’ in the Index.
Driver’s Temperature Knob
The center knob sets the temperature for the driver’s
outlets.
Turn the knob toward red (clockwise) for warmer
air. Turn it toward blue (counterclockwise) for cooler air.

Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down on very hot days, use MAX with
the temperature knobs all the way
in the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use
NORM with the
temperature knobs in the blue area. The system will
bring
in outside air and cool it.
On cool, but sunny days, the
sun may warm your upper
body,
but your lower body may not be warm enough.
You can use BI-LEV and set the temperature knob to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Heating
On cold days, use HTR with the temperature knobs all
the way in the red area. The system will bring
in outside
air, heat it and send it to
the floor ducts.
If your vehicle has an engine coolant heater, you can use

For maximum defroster performance, set both
driver and passenger temperature controls to the
warmest setting.
To warm passengers while keeping the windows clear,
use
BLEND.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The green arrows on your
instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about
to turn,
change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even
if the bulbs on
the trailer are burned out. Thus,
you may think drivers
behind
you are seeing your signal when they are not.
It’s important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 kmh) to reduce the
possibility
of engine and transaxle overheating.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to
do it:
1. Apply your regular brakes, but don’t shift into
PARK (P)
yet.
2. Have someone place chocks under the
trailer’s wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and shift to PARK
(P).
5. Release the regular brakes.
