rn 1 To Resume a Set Speed
A CAUTION:
If you leave your Cruise Control switch “ON”
when you’re not using Cruise, you might hit a
button and go into Cruise when you don’t
want to. You could be startled
and even lose
control. Keep the Cruise Control switch
“OFF”
~ until you want to use it.
2. Get up to the speed you want.
P
3. Push in the “SET”
button at the end of the
lever and release it.
4. Take your foot off the
accelerator pedal. Suppose you set your
Cruise Control at a desired
speed and then you apply
the brake.
This, of course,
shuts
off the Cruise
Control. But you don’t need
to.reset it. Once you’re
going about 25 mph (40
h/h) or more, you can
move the Cruise Control
switch. from
“ON” to
“WA” (Resume/Accelerate)
for about
half a second.
You’ll
go right back up to your chosen speed and stay
there.
If you hold the switch at “WA” longer than
half a second, the vehicle will keep going
faster
until you release the switch or apply the ,
brake. You could be startled and even lose
control.
So unless you want to go faster, don’t
hold the switch at

Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot
off the pedal, your vehicle will slow
down
to the Cruise Control speed you set earlier.
Using Cruise Control on Hills
How well your Cruise Control will work on hills
depends upon your speed, load, and the steepness
of the
hills. When going up steep hills, you may have
to step on
the accelerator
pedal to maintain your speed. When going
downhill, you may have to brake or shift
to a lower gear
to keep your speed down.
Of course, applying the brake
takes you out
of Cruise Control. Many drivers fmd this to
be too much trouble and don’t use Cruise Control on
steep hills.
To Get Out of Cruise Control
L
-.
There are two ways to turn
off the Cruise Control:
Step lightly on the brake
pedal;
OR
Move the Cruise switch
to
“OFF?
To Erase Cruise Speed Memory
When you turn off the Cruise Control or the ignition,
your Cruise Control set speed memory is erased.

Headlight “On” Warning
If you open the door while leaving the lights on, you will
hear a warning chime.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Running Lights” (DRL)
are a useful feature, in
that DIU can make your vehicle more visible to
pedestrians and other drivers during daylight hours. DRL
are required on new vehicles sold in Canada.
Your DRL work with a light sensor on top
of the
instrument panel. Don’t cover it up. The low beam
headlights will come on at reduced brightness
in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released.
At dusk, the exterior. lights will come bn &.nomatically
and the low
beams will change to full brightness. At
dawn, the exterior lights will go out and the low beams
will change to
the reduced brightness of DRL (if the
headlight switch is off).
Of course, you may still turn on the headlights any time
you need to.
To idle your vehicle with DRL off, set the parking brake
while the ignition is in the
“Off’ or “Lock” position.
Then start the vehicle. The
DRL will stay off until you
release the parking brake.

Fuel Gage
Your fuel gage tells you about how much fuel you have
left, when the ignition is on. When the indicator nears
“E” (Empty), you still have a little fuel left, but you
should get more
soon.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage and are
normal operating characteristics:
At the service station, the gas pump shuts off before the
gage reads
“F” (Full).
It takes a little more or less fuel to fill up than the gage
indicated. For example, the gage may have indicated the tank was half
full, but it actually took
a little more
or less than half the
tank‘s capacity to fill the tank.
The gage moves a little when you turn a corner, speed
up or brake.
The gage doesn’t go back to “E” when you turn off the
ignition.
Engine Oil Pressure Light
If you have a problem with
your
oil, this light may stay
on after you start your
engine, or come on when
you are driving.
This
indicates that oil is not
going through your engine
quickly enough to keep it
lubricated. The engine could be low on oil, or
could have some other oil
problem. Have it fixed right
away.
The
oil light could also come on in three other situations:
When the ignition is on but the engine is not funning,
the light will come on as a test to show you it is
working, but the light will go out when
you turn the
ignition to “Start? If it doesn’t come on with the

Volts Gage (Option)
When your engine is not
running, but
the ignition is
on (in the “Run” position),
the gage shows your
battery’s state of charge
in
DC volts. When the engine
is running, the gage shows
the condition of the
charging system. Readings
between the red warning
zones indicate the normal
operating range.
Readings in either red
warning zone indicate a possible problem in the electrical
system. Have your vehicle serviced immediately.
Brake System Warning Light
Your Buick‘s hydraulic
brake system is divided into
two parts. If one part isn’t working, the other part can still work and stop you. For
good braking, though, you
need both parts working
well.
If the warning light
goes on, there could be a
brake problem. Have your
brake system inspected right away.
This light should come on
as you start the vehicle. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a problem.
This light will also come on when you set your parking
brake, and will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while driving, pull
off the road and
stop carefully.
You may notice that the pedal is harder to
push. Or, the pedal may go closer to -the floor. It may take
longer to stop. If the light is still on, have the vehicle towed
for service. (See “Towing Your Buick” in the Index.)

A CAUTION:
Your brake system may not be working properly
if the brake warning light is on.
Driving with the brake warning light on can
lead to an accident.
If the light is still on after
you’ve pulled
off the road and stopped
carefully, have the vehicle towed
for service.
Engine Coolant Temperature Warning Light
---I
This light tells you that
your engine coolant has
overheated or your radiator
cooling
fan is 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 (Option)
‘1 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.
Also, the temperature symbol on the gage will come on
when your engine is too hot.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road:’ this manual shows what to
do. See “Engine Overheating” in the Index.

If necessary, you can use hand signals out the window:
Left arm straight out for a left turn, down for slow or
about-to-stop, and up
for a right turn.
Slowing down. If time allows, tap the brake pedal once
or twice in advance of slowing
or stopping. This warns
the driver behind you.
Disabled. Your four-way flashers signal that your vehicle
is disabled or is a hazard.
See “Hazard Warning
Flashers’’ in the Index.
Traffic Officer
The traffic police officer is also a source of important
information. The officer’s signals govern, no matter what
the traffic lights or other signs say.
The next section discusses some
of the road conditions
you may encounter.
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please
start with a very important sakty device in your Buick:
Buckle up.
(See “Safety Belts” in the Index.)
Defensive driving really means “be ready for anything:’
On city streets, rural roads, or freeways, it means
“always expect the unexpected:’ Assume that pedestrians
or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Expect children to dash out from behind parked cars,
often followed by other children. Expect occupants in
parked cars to open doors into traffic. Watch for movement
in parked cars-someone may be about to open
a door.
Expect other drivers to run stop signs when you are on a
through street. Be ready to brake
if necessary as you go
through intersections. You may not have to use the brake,
but if you do, you will be ready.
If you’re driving through a shopping center parking lot
where there are well-marked lanes, directional mows,
and designated parking areas, expect some drivers to
ignore
all these markings and dash straight toward one
part of the lot.
Pedestrians can be careless. Watch for them. In general,
you must give way to pedestrians even if you
know you
have the right of way.
Rear-end collisions
are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It’s the best defensive driving maneuver, in both
city and rural driving. You never know when the vehicle
in front of you is going
to brake or turn suddenly.
Here’s a final bit of information about defensive driving.
The most dangerous time for driving in the
U.S. is very

You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator.
All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you’re driving on snow
or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control of
your vehicle.
Braking
Braking action involves perception time and reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s
reaction time.
Average reaction time is about 34 of a second. But that’s
only
an average. It might be less with one driver and as
long as
two or three seconds or more with another. Age,
physical condition, alertness, coordination and eyesight
all play a part.
So do alcohol, drugs and frustration. But
even in
% of a second, a vehicle moving at 60 mph
(100 ludh) travels 66 feet (20 m). That could be a lot of
distance
in an emergency, so keeping enough space
between your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surf$ce of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; and the condition of your brakes.
Most drivers treat their brakes with care. Some, however,
overwork the braking
system with poor driving habits.
Avoid needless heavy braking. Some people drive in
spurts-heavy acceleration followed
by heavy
braking-rather than keeping pace with traffic.
This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes
will wear out much
faster
if you do a lot of heavy braking.

Don’t “ride” the brakes by letting your left foot rest
lightly
on the brake pedal while driving.

If you keep pace with the traffic and allow realistic
following distances, you
will eliminate a lot of
unnecessary braking. That means better braking and
longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder
to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when
you brake. Once the power assist
is used up, it may take longer to stop and the brake
pedal will be harder to push.
Disc Brake Wear Indicators
Your Buick has front disc brakes and rear drum brakes.
I A CAUTION:
The brake wear wamlng sound means that
sooner or later pur brakes won't work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your
vehlcle serviced.
I
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are Some driving conditions or climates may cause a brake
worn and new pads
are needed. The sound may come squeal when the brakes are first applied or lightly
and
go or be heard all the time your vehicle is moving applied. This do\
es not mean something is wrong with
(except when you are pushing on the brake pedal firmly). your brakes.
