Resynchronizing Your Remote Keyless
Entry Transmitter
After you have changed the battery in your transmitter,
you will need
to resynchronize the transmitter. To do
this, press the
LOCK and UNLOCK buttons on the
transmitter together and hold for approximately seven
seconds
or until three brief horn chirps are heard. You
will also need to use
this procedure if your vehicle has
lost battery power for an extended period
of time.
Trunk
It can be dangerous to drive with the trunk open
because carbon monoxide
(CO) gas can come into
your vehicle. You can’t see or smell
CO. It can
cause unconsciousness and even death.
If you must drive with the trunk open or if
electrical wiring or other cable connections must
pass through the seal between the body and
the trunk:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to
its highest speed with the setting
on VENT. That will force outside air into
your vehicle. See “Comfort Controls” in
the Index.

Ashtrays and Lighter
The center front ashtray is located on the instrument
panel, just below the comfort controls. To remove the
ashtray, open the lid and lift it out.
The rear ashtray is located within
a small door at the
back of your vehicle’s front
seat armrest. 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. 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.
Sun Visors
To block out glare, you can swing down the visors. You
can
also move them from side to side. The visors also
have extenders that
you can pull out for added coverage.

TEMP
This light
tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
The light should come on
briefly when your ignition
is turned on to show you
that it is working.
TEMPERATURE
You have a gage that shows
the engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is too hot!
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. 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

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 fm 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
(OOF (- 18°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

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.)
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
it to help your system provide warm air faster when it’s
cold outside (0°F
(- 1 SOC) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant

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 km/h) 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.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet.
Have someone place chocks under the
trailer’s wheels.
When the wheel chocks are
in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and shift
to PARK (P).
Release the regular brakes.
