/I CAUTION:
If you let your tires spin at high speed when the
“TRACTION OFF“ warning light is on, they can
explode and you or others could be injured. And,
spinning your tires with the “TRACTION OFF”
warning light on can cause the transaxle to
overheat
or can cause other problems. That
could
cause an engine fire or other damage.
When you’re stuck,
spin the wheels as little as
possible. Don’t spin the wheels above 35 mph

Engine Coolant
Temperature Warning
Light
TEMP
This light tells you that your engine coolant has
overheated or your radiator cooling fans are
not
working. If you have been operating your vehicle under
normal driving conditions, you should
pull off the road,
stop your vehicle and turn the engine
off as soon as
possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.

Engine Coolant Temperature Gage
If you have the Gage Cluster, 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.

A computer monitors operation of your fuel, ignition

when the ignition is on, but the engine is not running, as
a check to show
you it is working. If it does not come on
at all, have
it fixed right away. If it stays on, or it comes
on while you are driving, the computer
is indicating that
you have a problem. You should take your vehicIe in for
service soon.

To choose the temperature you want maintained inside
the car, push one of these.
You can choose from
60°F (16OC), for maximum
cooling, and
90 F (33 "C), for maximum heating. It is
not necessary to choose the extreme temperature to get
the system to heat
or cool at the maximum. The system
does it automatically.

When the system is off, the
ventilation system will
allow air to flow through
your Buick when
the
vehicle is moving. The
system will try
to keep the
air at the chosen
temperature, unless it is
very hot
or very cold
outside. The outside
temperature will show in
the display area when the
system is
OFF.

Air entering the car will be evenly split between the
floor outlets and
the outlets near the windshield.
The blower speed will be controlled automatically,
but
you can choose another fan speed by pushing the HI or
LO buttons.
Defrost
This setting will direct most
of the air flow toward the
windshield. Use this when
there is fog or ice on the
I windshield.
Defrost will work better if any ice and snow is cleared
from the hood and the air inlet area between
the hood
and
the windshield.
Blower speed will be controlled automatically, but
you
can choose another speed by pushing the HI or LO
buttons.
Rear Window Defogger (Option)
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
window. After
10 minutes,
it will go
off by itself or,
pressing the button again
during the heating cycle
will shut it
off. If you need
additional warming time,
push the button again.
If you have the heated outside rearview mirror option,
the mirror will be warmed when the rear defogger is on.
I NOTICE:
Scraping the inside of your rear winoow could
cut and damage the heater. Your warranty wou’” not cover this damage. Don’t put decal? +here,
you might have to scrape them off.

Bi-Level
This 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.
The Bi-level setting directs outside air into your vehicle
in two ways. Cool air is directed toward your upper
body through the instrument panel outlets, while slightly
warmed air is directed through the heater outlet at your
feet.
The air conditioner compressor operates in all Air
Conditioning positions and the Defrost position when
the outside temperature is above
48 OF (9OC).
When you don’t need to cool the outside air, use the
VENT, HEAT, or DEFROST settings. Adjust the
temperature control for comfort. You’ll get better fuel
economy (gas mileage) if you’re
not cooling the outside
air. When
you cool the air, your engine runs a
refrigeration compressor, and it has to work harder.
Vent
For mild outside temperature, when little heating or
cooling is needed, use the
VENT setting. Air will flow
through the instrument panel outlets. Use
the air outlets to
turn on, adjust and turn
off the air flow. Adjust the
temperature lever to the desired temperature.
Heater
When outside temperatures are cold, pressing the HTR
setting and adjusting the temperature lever
will send
warm air through the floor outlets, and some through the
defroster vents.
Def
The Defrost setting directs most of the air flow toward
the windshield. Use defrost when
you want to remove
fog or ice from
the windshield. When it’s 48 OF (9 “C) or
warmer, you’ll get cooled air.
Defog
Air entering the car will be evenly split between the
floor outlets and the outlets near the windshield. You
can control the temperature of the air and the fan speed
to clear the foggy windows.

Rear Window Defogger (Option)
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
1 window. After-10 minutes it
will go off by itself, or
pressing the button again
during the heating cycle will shut it off. If you need
additional warming time,
push the button again.
Scraping the inside of your rear window could
cut and damage the heater. Your warranty would
not cover this damage. Don’t put decals there
you might have to scrape them
off.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out your system if you acquaint
yourself with it first. Find
out what your Delco @ system
can do and how
to operate all its controls, to be sure
you’re getting the most out of the advanced engineering
that went into
it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). And,
tall buildings or hills can interfere with
FM signals,
causing the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble
to reduce this noise.

Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help
you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand
to the right. Always back up slowly and, if
possible, have someone guide you.
Making nrns
When you’re turning with a trailer, make wider turns
than normal. Do this
so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well
in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows
on your instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked up,
the trailer lights 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 to “D” (Drive) and
reduce your speed to around
45 mph (70 km/h) to
reduce the possibility of engine and transaxle
overheating.
