“Change Oil Soon” Light (Option)
CHANGE
OIL SOON
This light is activated by
the Engine Oil Life
Monitor System. It
indicates that the engine oil
has degraded enough to
require changing. (See
“Engine Oil” in the Index).
This is determined by electronically monitoring engine
speed, coolant temperature and vehicle speed. Since the
change interval is dependent upon driving habits and
conditions, the “Change Oil Soon” light may come on as
early as
2,000 miles or less for harsh conditions.
The “Change Oil Soon” light
is lit for three seconds as a
bulb check each time the ignition key is turned to the
RUN position. If an oil change is required, it will stay
on for
60 seconds each time the engine is started. If the
“Change Oil Soon” light is on continuously, there is a
problem with the Oil Life Monitor System and service is
required. After
changing; the engine oil, the system should be
- reset. This
will cause the “Change Oil Soon” light once
again,
to be lit for just the bulb check period of three
seconds.
The reset button is.inside this hole, which is under the
passenger’s side of the instrument panel, near the door.
With the ignition key in the
RUN position, but the
engine not started, use a pen to push the reset button,
holding
it in for at least 5 seconds but not more than 60
seconds. After 5 seconds, the “Change Oil Soon” light
will flash 4 times and then go off. This indicates that the
Oil Life Monitor System has been reset.

A CAUTION:
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle.
In an
emergency, you can use a cloth or a paper towel
to do
this; but be sure to use a scraper or wire
brush later,
if you need to, to get all the rust or
dirt
off.

0 SAE low-30
As shown in this chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s
going to be colder than
60 OF (1 6 ” C) before your
next oil change. When it’s very cold, below
0°F
(- 18 ” C), you should use SAE 5W-30.
These numbers on an oil container show
its viscosity, or
thickness. Do not use other viscosity oils such as SAE
low-40 or SAE 20W-50.

Engine Oil Additives: Don’t add anything to your oil.
Your Buick dealer is ready
to advise if you think
something should be added.
When to Change Engine Oil: See if any one of these
is true for
you:
0 Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.

10 miles
(16 km).
Most trips are through dusty places.
If any one of these is true for your vehicle, then
you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Soon” in the Index.)
If none of them is true, change the oil every 7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change
the filter at the first oil change and at every
other oil change after that. (See “Change
Oil Soon” in
the Index.)

big help
if you have to park outside in very cold
weather,

this option, see “Engine Block Heater.”

Refer to the Maintenance Schedule to determine when
to replace the air filter.
See “Scheduled Maintenance Services’’ in the Index.
A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame
if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the air cleaner off.

Automatic Transaxle Fluid
When to Check and Change:
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check:
Because this operation can be a little difficult, you may
choose to have this done at a Buick dealership Service Department.
If
you do it yourself, be sure to follow all the
instructions here, or
you could get a false reading on the

What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM
Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification
1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change. If you use these, you
don’t need
to add anything else.
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and a proper antifreeze.
If you use an improper coolant mix, your

A Word About Maintenance
We at General Motors want to help you keep your
vehicle
in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time
in very hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work, to do errands or in many other
ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary. You may
even need
more frequent checks and replacements than
you will
find
in the schedules in this part. So please read this part
and
note how you drive. If you have any questions on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners choose
to
have their maintenance work done. Your dealer can be
relied upon to use proper parts and practices.

Section
D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before you or anyone else drives
the vehicle.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification” in the Index.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or
“SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE
5W-30 or SAE 10W-30), see “Engine Oil” in
the Index. If your vehicle has an Engine
Oil Life
Monitor,
the monitor will show you when to change
the oil. See “Engine Oil Life Monitor” in the Index.

Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate the
suspension and steering linkage.
Throttle Body Mounting Bolt Torque” -- Check
the torque
of the mounting bolts and/or nuts.
Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following the instructions in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check

1825M. Keep
coolant at the proper mixture
as specified. See
“Coolant” in the Index. This provides.proper freeze
protection, corrosion inhibitor level and engine
operating temperature.
The U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.
