1997 BUICK CENTURY check engine

Avoid needless heavy bralung. 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. 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.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when
you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this
test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light” in the Index.

The exit speed is usually posted.
Reduce your speed according to your speedometer,
not
to your sense of motion. After driving for any distance
at higher speeds,
you may tend to think you are going
slower than you actually are.
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’ll 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:

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 and your instruments frequently.
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.
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.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
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.
- __
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They 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. Always have your engine running
and your vehicle
in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or cut
across
the center of the road. Drive at speeds that let
you stay in your own lane.
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.

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.
’ A CA”T1CY:
Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell it,
so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that
is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep CO out.
You can run the engine to keep warm, but be careful.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The green arrows on your
instrument panel will flash whenever you signal a turn
or lane change. Properly hooked
up, the trailer lamps
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 and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet.
Have someone place chocks under the
trailer’s wheels.
When the wheel chocks are
in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and shift
to PARK (P).
Release the regular brakes.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important
in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each of these
is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

6. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged too.
Before you connect the cables, here are some basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect positive (+) to
negative
(-) or you’ll get a short that would damage
b
the battery and maybe other parts too.

Fans or other moving engine parts can injure you
badly. Keep
your hands away from moving parts
once the engine is running. 7. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Use a
remote positive (+) terminal if the vehicle has one.
