AM Stereo
This means the Delco@ system can receive C-QUAM@
stereo broadcasts. Many
AM stations around the country
use C-QUAM@ to produce stereo, though some
do not.
(C-QUAM@ is
a registered trademark of Motorola, Inc.)
If your D~ICO@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.

0 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.
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.
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.
A computer senses that wheels are slowing down. The
computer separately works the brakes at each front
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.

applied. This does not mean something is wrong with
your brakes.
Rear Drum Brakes
Your rear drum brakes don’t have wear indicators, but if
you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are
removed for rotation
or changing. When you have the
front brakes replaced, have the rear brakes inspected,
too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This
could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your
brakes adjust for wear.
If you rarely make a moderate or heavier stop, then your
brakes might not adjust correctly. If you drive in that
way, then
-- very carefully -- make a few moderate brake
stops about every
1000 miles (1600 km), so your
brakes will adjust propexly.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same time.
In many emergencies, steering can help you more than
even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but it
will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver
lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving
on curves. The
traction
of the tires against the road surface makes it
possible for the vehicle to change its path when you turn

two-lane roads. Reconsider before passing the
next
vehicle.

following driver to get ahead of you. Perhaps
you
can ease a little to the right.
If you’re being passed, make it easy for the
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road
to do what the driver has asked.
In
any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by
not “over-
driving” those conditions. But skids are always possible. The
three types of skids correspond
to your Buick‘s
three control systems. In
the braking skid your wheels
aren’t rolling. In
the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid too
much throttle causes the driving wheels
to spin.
A cornering skid and an acceleration skid are best
handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide (as when
you turn a comer
on a wet, snow-or icexovered road), ease your foot off
the accelerator pedal as soon as your feel the vehicle start
to slide. Quickly steer the way
you want the vehicle to
go. If you start steering quickly enough, your vehicle will
straighten
out. As it does, straighten the front wheels.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is
on the road. For safety, you’ll
want
to slow down and adjust your driving to these
conditions. It is important to slow down
on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving
on a surface with reduced traction, try
your best
to avoid sudden steering, acceleration, or
braking (including engine braking by shifting
to a lower
gear). Any sudden changes could cause tires to slide.
You may
not realize the surface is slippery until your

Driving a Long Distance
Although most long trips today are made on freeways,
there are still many made on regular highways. Long-distance driving on freeways and regular
highways is the same in some ways. The trip has to be
planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer turns
behind the wheel. You’ll enjoy your trip more if you and
your vehicle are in good shape. Here are some tips for a
successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive
in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained,
it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’!! find experienced and able service experts in
Buick dealerships all across North America. They’ll be
ready and willing to help
if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are

Wiper Blades: Are they in good shape?
Fuel, Engine Oil. Other Fluids: Have
you checked
all levels?
Lights: Are they all working? Are the lenses clean?
- Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip
a short
time to avoid a major storm system?
Maps:
Do you have up-to-date maps?
On the Road
Unless you are the only driver, it is good to share the
driving task with others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours at a sitting.
Then, either change drivers or stop for some refreshment
like coffee, tea
or soft drinks and some limbering up.
But do stop and move around. Eat lightly along the way.
Heavier meals tend to make some people sleepy.

On two-lane highways or undivided multilane highways
that do not have controlled access, you’ll want to watch for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers with direct access to the highway, no passing zones and school zones, vehicles turning left and right off the road,
pedestrians, cyclists, parked vehicles, and even animals.
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch
of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don’t let it
happen to you! If it does, your vehicle can leave the
road in less than a second, and you could crash and be
injured. What can you
do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to
the sides. Check your rearview mirrors frequently
and your instruments from time
to time. This can
help you avoid
a fixed stare.
Wear good sunglasses in bright light. Glare can
cause drowsiness. But don’t wear sunglasses at
night. They will drastically reduce your overall
vision
at the very time you need all the seeing power
you have.
If you get sleepy, pull off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
As in any driving situation, keep pace with traffic and
allow adequate following distances.

Hill and Mountain Roads
-.
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
If you drive regularly in steep country, or if you're
planning to visit there, here are
some tips that can make
your trips safer and
more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain
roads.
Know how to go down hills. The most important
thing
to know is this: let your engine do some of the
slowing down. Don't make your brakes do it all.
Shift
to a lower gear when you go down a steep or
long hill. That way, you will slow down without
excessive use of your brakes.
A CAUTION:
If you don't shift down, your brakes could get so
hot that they wouldn't work well. You would then
have poor braking
or even none going down a
hill. You could crash. Shift down to let your
engine assist your brakes on
a steep downhill
slope.

1 A CAUTION:
Coasting downhill in “N” (Neutral) or with the
ignition
off is dangerous. Your brakes will have
t get so hot that they wouldn’t work well. You
could crash. Always have your engine running
and your vehicle in gear when
you go downhill.

0 Stay in your own lane when driving on two-lane surprised by a vehicle coming toward
you in the
same lane.
0 It takes longer to pass another vehicle when you’re
going uphill. You’ll want to leave extra room to pass.
If a vehicle is passing you and doesn’t have enough
room, slow down to make it easier for the other
vehicle
to get by.
0 As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones,
a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.
0 Winter driving can present special problems. See “Winter Driving” in the Index.

Winter Driving 0 You may want to put winter emergency supplies in
your trunk.
Here are some tips for winter driving:
0 Have your Buick in good shape for winter. Be sure
your engine coolant mix
is correct.
0 Snow tires can help in loose snow, but they may give
you less traction
on ice than regular tires. If you do
not expect
to be driving in deep snow, but may have
to travel over ice, you may not want to switch to
snow tires at all. Include an ice scraper,
a small brush
or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth, and a
couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag
of
sand, a piece of old carpet or a couple of burlap bags to
help provide traction. Be sure you properly secure these
items in your vehicle.
185

passengers safe: Turn on your hazard flashers. Tie a red
cloth to your vehicle to alert police that you’ve been
stopped
by the snow. Put on extra clothing or wrap a
blanket around you.
If you have no blankets or extra
clothing, make body insulators from newspapers, burlap
bags, rags, floor mats
-- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.

CAUTION: (Continued)
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go
a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged.
You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
