Headlights Reminder Light (Canada Only)
If your vehicle was first sold, when new, in Canada, this
light will
go on at night to remind you to turn on the
headlights.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that
“Daytime Running Lights” (DRL) are
a useful feature,
in that DRL 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 high 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 night, the headlights reminder light on the instrument
panel will come on to remind
you to turn on the
headlights. When
you turn on your headlights, the DRL
will switch
off and the exterior lights will come on.
When
you turn off the headlights, the exterior lights will
go out and the high beams will change to the reduced
brightness of DRL again. Of course, you may still turn on the headlights
or flash to pass any time you need to.

Brake System Warning Light

gage reads “F.” 1 ,

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
Car” in
the Index.)

LOCK
With anti-lock, this light will go on unless you start your
engine and it will stay on for three .seconds. If the light
doesn’t come on, have it fixed
so it will be ready to
warn
you if there is a problem.
If the light stays on or comes on when you’re driving,
stop as soon
as possible and turn the key off. Then start
the engine to reset the system. If the light still stays on,
or comes on again while you’re driving, your Buick
needs service. Unless the regular brake system warning
light is also on, you will still have brakes, but not

Pavement markings add to traffic signs and signals.
They give information to drivers without taking
attention from the roadway. A solid yellow line on your
side of the road or lane means “don’t cross.”

Turn and lane change signals. Always signal: when you
plan to turn or change lanes.
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 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.
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. 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
early on Sunday morning. In fact,
GM Research studies
show that the most and the least dangerous times for
driving, every week, fall an the same day. That day is
Sunday. The most dangerous time is Sunday fi-om

to 4 a.m. The safest time is Sunday from 10 a.m. to
11 a.m. Driving the same distance on a Sunday at 3 a.m.
isn’t just a little more dangerous than it is at 10 a.m. It’s
about 134 times more dangerous!
That leads to the next section.

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
3/4 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; 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.

I A CAUTION.:
“Riding” your brakes can cause them to overhe;
to the point that they won’t work well. You mighl

in time to avoid
an accident. If you “ride” your brakes, they will

If you keep pace with the traffic and IW realistic
following distances, you will eliminate a lot
of
unnecessary braking. That means better braking and
longer brake life.
If your I- -dine 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.
Anti-Lock Brakes (ABS)
Your Buick has an advanced electronic braking system
that will help prevent skidding.
This light on the instrument panel will go on when you
start your vehicle.
TI-
LOCK
150

When you start your vehicle and begin to drive away,
you may hear a momentary motor or clicking noise. And you may even notice that your brake pedal moves a little
while this is going on. This
is the ABS system testing
itself.
If you have your foot on the brake pedal, this
check won’t happen until the vehicle goes about 4.mph
(6 km/h) or until you take your foot off the brake pedal.
After an ABS stop, you may hear a clicking noise the
next time the vehicle goes about
4 mph (6 km/h).
If there’s a problem with the anti-lock brake system, the
anti-lock brake system warning light will stay on or
flash.
See “Anti-lock Brake System Warning Light” in the
Index.
Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. Here’s what happens with
ABS.
151
~

A computer senses that wheels are slowing down. The
computer separately works the brakes at each fmnt
wheel and at the rear wheels.
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most
of available tire and road
conditions.
__
r
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
A CAUTION:
Anti-lock doesn’t change the time you need to
get your foot up to the brake pedal.
If you get too
close to the vehicle
in front of you, you won’t
have time to apply your brakes
if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you have
anti-lock brakes.
To Use Anti-Lock:
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You also may hear a
clicking noise as you accelerate after a hard stop.
Disc Brake Wear Indicators
Your Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing on the brake pedal firmly).
