Supplement to the 1997 Buick Regal and Century Owner’s Manuals
This is a correction to information found on page 6-40 (Regal only) and page 6-38 (Century only).
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the inside of the trunk lid shows the correct inflation
pressures for pur tires when they’re cold. “Cold” means your vehicle has been sitting for at least three
hours or driven no more than
1 mile (1.6 km).
This is a correction to information found
on page 6-63 (Regal only).

The oil light could also come on in the following situations:
The light will come on briefly when you turn on the
ignition to show you that it is working properly.
(If it
doesn’t come on with the ignition on, you may have
a
problem with the fuse or bulb. Have it fixed right away.)
0 Sometimes when the engine is idling at a stop, the
light may blink on and
off. This is normal.
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You
or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems can be costly and is not covered by
your warranty.
Low Oil Level Light
LOW
OIL
Your engine is equipped with
an oil level monitoring
system. When
the ignition
key is turned on, the
LOW
OIL light will come on
briefly.
If the light does not
come on briefly, have it fixed
so it will be ready to warn
you if there’s a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine
off. Check the oil level using the
engine oil dipstick. (See “Engine Oil” in the Index.)
If
the light does not flash, have the low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
The oil level monitoring system only checks oil level
during the brief period between key
on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if
the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation to drain back into the oil pan.

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:

Lumps: 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?

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Electric Engine Fans
C. Radiator Pressure Cap
h!~ CAUTION:
An electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.
ProCarManuals.com

Before closing the hood, be sure all the filler caps are
on properly. Then just pull the hood down and close
it firmly.
3800 Supercharged (Code 1) Engine
(If Equipped)
Your Buick may have a 3800 Supercharged engine.
The supercharger is a device which is designed to
pump more air into the engine than it would normally
use. This air is mixed with fuel, which creates increased
engine power. Since the supercharger is a pump and is
driven from an engine accessory drive belt, increased
pressure is available at all driving conditions.
The powertrain control module
(PCM), works with
a vacuum control to regulate the increased pressure
required during specific driving conditions. When
this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
supercharger
is pumping is routed through a bypass.
All of these controls working together provide high
performance character and fuel efficiency in the
3800 Supercharged L67 engine.
Engine
I --
LOW
OIL
If the LOW OIL light on
the instrument panel comes on, it means you need to
check your engine oil level right away. For more
information, see
“Low Oil
Level Light” in the Index.
You should check your
engine oil level regularly;
this is an added reminder.
It’s
a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.

Supercharger Oil
Unless you are technically qualified and have the proper
tools, you should let your dealer or a qualified service
center perform this maintenance.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs first.
What Kind of Oil to Use
See “Recommended Fluids and Lubricants’’ in the Index
and use only the recommended oil.
How to Check and Add Oil
Check oil only when the engine is cold. Allow the
engine to cool two to three hours after running.
If you remove the supercharger oil fill plug while
the engine is hot, pressure may cause
hot oil to
blow out
of the oil fill hole. You may be burned.
Do not remove the plug until the engine cools.
1.
2.
3.
3.
Clean the area around the oil fill plug before
removing it.
Remove
the oil fill plug using a 3/16 inch Allen
wrench.
The oil level is correct when
it just reaches the
bottom
of the threads of the inspection hole.
Replace the oil plug with the O-ring
in place.

Using Solvent-vpe Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will
clean off better with just
water and mild soap.
If you need to use a solvent:
1.
2.
3.
4.
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside of the stain, “feathering” toward
the center.
Keep changing to a clean section of the cloth.
When you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
Special Cleaning .oblems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt
can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them to spread.
Non-Greasy Stains
Stains caused by catsup, coffee (black), egg, fruit, fruit
juice, milk, soft drinks, wine, vomit, urine and blood
can be removed as follows:
1. Carefully scrape off excess stain, then sponge the
2. If a stain remains, follow the foam-type instructions
