What Kind of Oil to Use (CONI)
SAE 1OW-30 (3800 V6 Engine)
As shown in the viscosity 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°F
(16°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 1OW-40 or SAE 20W-50.
For best fuel economy and cold starting,
select the
lowest SAE viscosity grade oil
for the expected temperature range. I

The CertificatiodTire label is found on
the rear edge of the driver's door.
The label shows the size
of your original
tires and the inflation pressures needed
to obtain the gross weight capacity of
your vehicle. This is called the
GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle,
all occupants, fuel and cargo.
The CertificatiodTire label also tells
you the maximum weights for the front
and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the
actual loads on your front and rear
axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load equally on both sides
of the
centerline.
Never exceed the
GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the &ont or
rear axle.
And, if you do have a heavy load, you
should spread
it out.
Electronic Level Control
On vehicles equipped with optional
electronic level control, the rear of the
vehicle
is automatically kept level as you
load or unload your vehicle. For more
about
this option see the Index under
Electronic Level Control.

Inflation-Tire Pressure
The CertificatiodTire label which is on
the rear edge of the driver’s door shows
the correct inflation pressures for your
tires, when they’re cold. “Cold’’ means
your vehicle has been sitting for at least
three hours or driven no more than a
mile. Don’t
let anyone tell you that
underinflation
or overinflation is
all right. It’s not. If your tires don’t
have enough air (underinflation),
you can get:
Too much flexin1
Too much heat
Tire overloadine
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air
(overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
I
When to Check:
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 kPa).
How to Check:
Use a good quality pocket-type gage to
check tire pressure. Simply looking at
the tires will not tell you the pressure,
especially if you have radial tires-
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Foreign Material
Calcium chloride and other salts, ice
melting agents, road
oil and tar, tree sap,
bird droppings, chemicals from
industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces. Use
cleaners that are marked safe for painted
surfaces for these
stains.
Finish Damage
Any stone chips, fractures or deep
scratches in the fmish should be
repaired right away.
Minor chips and scratches can be
repaired with touch-up materials available from your dealer or other
service outlets. Larger areas
of finish
damage can be corrected
in your
dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect on
the underbody. If these are not removed,
accelerated corrosion (rust) can occur
on the underbody parts such as fuel
lines, frame, floor pan, and exhaust
system even though they have corrosion
protection.
At least every spring, flush these
materials from the underbody with plain
water. Clean any areas where mud and
other debris can collect. Dirt packed in
closed areas of the frame should be
loosened before being flushed. Your
dealer or an underbody vehicle washing
system can do this for you.

/njector 3365 Fuse
(3800 V6 ENGINE ONLY)
This 20-amp fuse is located underhood,
on a bracket just behind the passenger
side headlight.
It is mounted on the face
of the bracket in the position closest to
the passenger side of the vehicle. The
fuse services the injectors, fuel pump,
oil pressure sender and fuel pump
switch.
To access the fuse, pry back the latch
with a screwdriver,
then pull down on
the base of the unit. If you need to
replace the fuse, be sure to use a
20-amp fuse.
Push the base of the unit
firmly up into
the cover until
the latch snaps into the
locked position.
Head/ight Wiring
The headlight wiring is protected by a
circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain off.
If this happens, have your
headlight system checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and
a fuse. If the
motor overheats due to heavy snow, etc.
,
the wiper will stop until the motor
cools. If the overload is caused by some
electrical problem, have it fixed.
Power Windows and Other
Power Options
Circuit breakers in the circuit
breakerhelay panel protect the power
windows and other power accessories.
When the current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the problem
is fixed.

How This Part is Organized
The remainder of this part is divided into five sections:
Section
A: Scheduled Maintenance Services shows what to
have done and how often. Some of these services can be
complex,
so unless you are technically qualified and have
the necessary equipment,
you should let your dealer’s
service department or another qualified service center do
these jobs.
I
A
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can bc
seriously injured.
Do your own maintenance work
only if you have the required know-how and the proper
tools and equipment for the job. If you have any doubt,
If you are skilled enough to do some work on your vehicle,
you will probably want to get the service information GM
publishes. You will find a list
of publications and how to get
them in this manual. See the
Index under Service
Publications.
Section B: Owner Checks & Services tells you what should
be checked whenever
you stop for fuel. It also explains what
you can easily do to help keep your vehicle in good
condition.
Section C: Periodic Maintenance Inspections explains
important inspections that your Oldsmobile dealer’s service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & Lubricants lists some
products GM recommends to help keep your vehicle
properly maintained. These products, or their equivalents,
should be used whether you do the work yourself or have it
done.
Section
E: Maintenance Record provides a place for you to
record the maintenance performed
on your vehicle.
Whenever any maintenance
is performed, be sure to write it
down
in this section. This will help you determine when
your next maintenance should be done. In addition, it is a
good idea to keep your maintenance receipts. They may be
needed to qualify your vehicle for warranty repairs.
