Engine BUICK REGAL 1997 Service Manual

Heating
On cold days, use HTR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Ventilation System
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in
the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, use
FRONT and full hot
(90°F (32°C)). Driver sets
temperature and selects high fan speed.
To warm
passengers while keeping the windows clear, push the
AIR FLOW button until WINDSHTELDFLOOR
appears
in the display. Select fan speed for comfort and
windshield clearing performance. Adjust the direction
of
airflow by moving the
louvered vents.
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when
it is moving. Outside
air will also enter the vehicle when the
air conditioning
fan is running.
If the airflow seems very low when the fan knob is
turned to the highest setting regardless of
the mode
setting, your passenger compartment air filter may need
to be replaced. See “Maintenance Schedule” in
the Index.

Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
[NOTICE:
Don’t use a razor blade or anything else sharp on
the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered
by your warranty.

To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound
equipment may interfere with the operation
of
your vehicle’s engine, Delco radio or other
systems, and even damage them. Your vehicle’s
systems may interfere with the operation
of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for
50 hours without
resetting the tape clean timer. If this message appears on
the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible to prevent damage to your tapes and
player. If you notice a reduction in sound quality, try a
known good cassette to see if it
is the tape or the tape
player at fault.
If this other cassette has no improvement
in sound quality, clean the tape player.

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. 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.
ProCarManuals.com

Remember: Anti-lock doesn’t change the time you need
to get your foot up
to the brake pedal or always decrease
stopping distance. 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.
-‘sing Anti-Lock
uon’t pump the brakes. Just hold the brake pedal
down and let anti-lock work for you. You may feel the
system working, or you may notice some noise, but this
is normal.
LOW TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
Traction Control System
(With
3800 Supercharged Engine)
Your vehicle has a traction control system that limits wheel
spin. This is especially useful
in slippery road conditions.
The system operates only if it senses that one or both
of
the front wheels are spinning or beginning to lose traction.
When this happens,
the system works the front brakes and
reduces engine power to limit wheel spin.
LOW TRAC
This light will come on
when your traction control
system is limiting wheel
spin. See “Traction Control
System Active Light” in
the Index.
You may feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. (See “Cruise Control”
in the Index.)
ProCarManuals.com

Enhanced Traction System (Option: Not
Available with
3800 Supercharged Engine)
Your vehicle may have Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions, The system operates only if it
senses that one or both of the front wheels are spinning
or beginning to lose traction. When
this happens, the
system reduces engine power and may also upshift the
transaxle to limit wheel spin.
LOW TRAC
This light will come on
when
your Enhanced
Traction System is limiting
wheel spin. See “Enhanced
Traction System Active
Light” in the Index. You
may feel or hear the system
working, but this is normal.
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in the Index.
TRAC
OFF
When the system is on and
the parking brake is
fully
released, this warning light
will come on to
let you
know if there’s a problem
with the system.
See “Enhanced Traction System Warning Light”
in the
Index. When this warning light
is on, the system will not
limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But
you can turn the system off if
you ever need to. (You should turn the system off if your
vehicle ever gets stuck
in sand, mud, ice or snow. See
“Rocking Your Vehicle”
in the Index.)

To turn the system on or
off, press the
TRACTION
button on the black panel
located directly behind
your automatic transaxle
shift lever.
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on.
If the
Enhanced Traction System is limiting wheel spin when
you press the button to turn the system off, the warning
light will come on
-- but the system won’t turn off right
away. It will wait until there’s no longer a current need
to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The Enhanced Traction System
warning light should go off.
Braking in Emergencies
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 is not functioning,
you can steer but
it will take much more effort.
Magnasteer TM
This steering system provides lighter steering effort for
parking and when driving at low speeds. Steering effort
will increase at higher speeds for improved road feel.
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
the front wheels. If there’s no traction, inertia will keep
the vehicle going in
the same direction. If you’ve ever
tried
to steer a vehicle on wet ice, you’ll understand this.
ProCarManuals.com

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten
out. Always be ready for a
second skid
if it occurs.
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 the tires to
slide. You may not realize the surface
is slippery until
your vehicle is skidding. Learn
to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface’’
-- and slow
down when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
Driving at Night

Night driving is more dangerous than day driving. One
reason is that
some drivers are likely to be impaired -- by
alcohol or drugs, with night vision problems, or by fatigue.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires do not have much tread or if the pressure
in one or
more is low. It can happen
if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
I NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
0
0
Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear
room
ahead, and be prepared to have your view restricted
by road spray.
Have good tires with proper tread depth. (See
“Tires” 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
