In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.
Low Coolant Warning Light
I
1
If you have this light and it
comes on, your system
is
low on coolant and the
engine may overheat.
See “Engine Coolant” in the Index and have your
vehicle serviced as soon as you can.
Engine Oil Pressure Light and Gage
0‘ 1
I
This light tells you if there could be a problem with your
engine oil pressure.
If your car has the optional gage cluster, you can read
your oil pressure directly from the gage
on your
instrument panel.
There are three ways this light can come on briefly,
which
is normal and doesn’t show a problem. They are:
The light comes on when you turn your key to
“Run.” It goes off once you turn
it to “Start.” That’s
just a check to be sure the light works. If it doesn’t,
be sure to have it fixed so it will be there to warn you
if something goes wrong.

If you’re “idling” at a stop sign, the light may blink
on and then
off.
If you make a hard stop, the light may come on for a
moment.
But, when this light comes on and stays on, it means
oil isn’t going through your engine properly.
You could
be low on oil, or you might have some other oil
problem.
A CAUTION:
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.
“Check Oil Level’’ Light (Option)
CHECK
OIL LEVEL
The “Check Oil Level”
light is lit for three seconds
as a bulb check each time
the ignition key is turned
to
the RUN position. If the
light doesn’t come on, have
your vehicle serviced.
If the engine oil is more than one quart low, the light
will come on briefly, then go off for 15-25 seconds, and
then come back
on for 20-40 seconds.
However,
if it has not been more than eight minutes
since the engine was last shut
off, the system will not
register low engine oil condition.
If the “Check Oil Level” light comes back on, the
engine
oil should be checked at the dipstick and then
brought up to the proper level if necessary. See “Engine
Oil” in the Index.

“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.

braking before moving onto the exit ramp.
Unfortunately, not all deceleration
lanes are long enough
-- some are too short for all the braking. Decide when to
start braking. If you must brake on the through lane, and
if there is traffic close behind
you, you can allow a little
extra time and flash your brake lights (in addition to
your turn signal) as extra warning that you are about to
slow down and exit.
The exit ramp can be curved, sometimes quite sharply.
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. For example,
40 mph (65 km/h) might
seem like only
20 mph (30 km/h). Obviously, this could
lead to serious trouble on a ramp designed for
20 mph
(30 km/h)!
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’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:
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
all levels?

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;
0 Shift into a gear; and
0 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.

I A 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.
. .” P
The coolant level should be at or above “FULL COLD.”
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
I I
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.

If there seems to be no leak, check to see if the electric
engine fans are running. If the engine
is overheating,
both fans should be running. If they aren’t, your vehicle
needs service.

Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
Fuel that is more than 5% methanol is bad for
your vehicle. Don’t use it.
It can corrode metal
parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t be covered under your Warranty. And even at
5%
or less, there must be “cosolvents” and
corrosion preventers in this fuel to help avoid
Gasolines for Cleaner Air
Your use
of gasoline with detergent additives will help
prevent deposits from forming
in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines are now blended with materials called
oxygenates. General Motors recommends that you use
gasolines with these blending materials, such as MTBE and ethanol.
By doing
so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
Fuels in
Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled,
the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All
of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business
in the
country where you’ll be driving.

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
V6 Supercharged Buick engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule’’ in the Index for when you
should check the fluid.
The supercharged
3800 engine uses two accessory drive
belts. One belt drives the generator and the power
steering pump. The second belt drives the supercharger,
coolant pump and air conditioning compressor. Each
belt has
its own tensioner and idler pulley. See
“Maintenance Schedule’’ in the Index for when you
should check the accessory drive belts and supercharger
oil level. Have your dealer check the oil level in the
supercharger.
Engine Oil
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.
The engine oil dipstick is
directly behind the engine
fan. Turn
off the engine and
give the oil a few minutes
to get back down into the
oil pan. If you don’t, the oil
dipstick might not &ow the
actual level.
ProCarManuals.com

To Check Engine Oil:
Pull out the dipstick and
clean it with a paper towel
or cloth, then push it back
in all the way. Remove it
again, keeping the tip
lower.
I
i
When to Add Oil: If the oil is at or below the ADD
line you’ll need to add some oil. But you must use the
right kind. This section explains what kind of oil to use.
For crankcase capacity, see “Capacities and
Specifications”in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper operating range, your engine could be damaged,
Use the engine oil fill cap next to the oil dipstick to add
oil.
Just
fill it enough,to put the level somewhere in the
proper operating range. Push the-dipstick all the way
back in when you’re through.
