If you pull the knob out
halfway,
it will turn on only
your parklamps. If you pull
the knob all the way out,
your headlamps
will then
come on.
Push the knob
in all the way to turn off the lamps.
A warning chime will sound if you open the driver’s
door when you turn the ignition switch to
OFF, LOCK
or
ACC with the lamps on.
Daytime Running Lamps / Automatic
Headlamp Control
Daytime Running Lamps (DRL) can make it easier for
others to see the front
of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful
in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel makes the
DRL work,
so be sure it isn’t covered.
The DRL system will make your front turn signal lamps
come on when:
0 The ignition is on,
0 The headlamp switch is off and
0 The parking brake is released.
When the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker and
other lamps won’t be on. Your instrument panel won’t
be lit up either.
When it’s dark enough outside, your front turn signal
lamps will turn off and your vehicle’s headlamps and
parklamps will turn
on. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, your headlamps will
go
off and your front turn signal lamps will come on.
To idle your vehicle with the DRL off, set the parking
brake while
the ignition is in OFF or LOCK. Then start
your vehicle. The DRL, headlamps and parklamps will
stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.

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 comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briefly when you turn
the ignition key
to RUN.
If it doesn’t come on then,
have it fixed
so it will
be ready to warn you if
there’s a problem.
BRAKE
If the light comes on while you are 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, or
if the anti-lock brake system warning light
is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your Vehicle” in
the Index.)
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on or if the
anti-lock brake system warning light is flashing
after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
When the ignition is on, the brake system warning light will also come on when you’ set your parking brake. The
light 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.

Anti-Lock Brake System Warning Light
ANTI -
LOCK
With the anti-lock brake
system, this light will
come
on when you start
your engine and it will
stay on for three seconds.
That’s normal.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with your
regular brakes. 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.
Have the vehicle towed for service. (See “Towing Your
Vehicle” in the Index.)
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing can lead
to an accident. After you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.
I
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Buick needs service. If the
light
is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn
you if there is a problem.

Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a
very important safety 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.
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.

Control of a Vehicle
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.
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 3/4 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 314 of a second, a vehicle
moving at
60 mph (100 km/h) 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 surface of the road (whether it’s pavement or
gravel); the condition of the road (wet,
dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
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.
