Underhood Light
Your underhood light will go on when
you open the hood.
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.
Turn off the engine and give the oil a
few minutes to drain back into the oil
pan.
If you don’t, the oil dipstick might
not show the actual level.
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, and check the level.

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,
you should
use
SAE 5W-30. These numbers on an

As shown in the chart, SAE 5W-30 is
best for your vehicle. However, you can
use SAE 1OW-30 if it’s going
to be 0°F
(-18°C) or above. These numbers on an
oil container show
its viscosity, or

Do not use other viscosity oils,
such as SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
“SH’ or “SG’ must be on the oil container,
either by itself or combined with other
quality designations, such as “SHKD,”
“SH,SG,CD,” “SG/CD,” etc. These
letters show American Petroleum
Institute (API) levels of quality.
SAE 1OW-30 (3800 engine)
SAE 5W-30 (3100 engine)
Energy Conserving I1
Oils with these words on the
container will help you save fuel.
These three things are usually included
in a doughnut shaped logo (symbol) on
most containers.
If you cannot find oils
with the “starburst” symbol,
you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above. If
you use oils that do not have
either the “starburst” symbol or an
API SH or
SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your
Oldsmobile 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:
Most trips are less than 4 miles (6 ltm).
It’s below freezing outside and most
trips are less than
10 miles (16 ltm).
The engine is at low speed most of the
time
(as in door-to-door delivery, or in
stop-and-go traffic).
You tow a trailer often.
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 ltm) or 3
months - whichever comes first.
If none
of them is true, change the oil
every
7,500 miles (12 500 ltm) or 12
months -whichever comes first.
Change the filter at the first oil change
and at every other oil change after that.
Engine Coolant Heater (Engine
Block Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see
Engine
Coolant Heater in the Index. 193

Loading Your Vehicle
The Certification/Tire 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 Certification/Tire 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 front 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.
Using heavier suspension components
to get added durability might not
change your weight ratings. Ask your
dealer to help you load your vehicle the
right way.
NOTICE:
Your warranty does not cover parts
or components that fail because
of
overloading.
If you put things inside your vehicle-
like suitcases, tools, packages, or
anything else-they will go
as fast as
the vehicle goes.
If you have to stop or
turn quickly! or if there is a crash,
they'll keep going.

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.
NOTICE:
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 flexing
Too much heat
Tire overloading
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
hazards.
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 1tPa).
How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply loolting 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.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See
Scheduled
Maintenance Services
in the Index.
Use this rotation pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the CertificationlTire label.
Make certain that all wheel nuts are
properly tightened. See
Wheel Nut
Toque in the Index.
ProCarManuals.com

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.
I Collision Repair
Your vehicle was built with composite
SMC (Sheet Molded Compound)
fiberglass body panels and molded
RIM
(Reaction Injection Molded) front
fenders and bumper covers. These
panels require different collision repair
procedures than metal-paneled vehicles.
See your Oldsmobile dealer for
information on collision repair.
I Chemical Paint Spotting
Some weather and atmospheric
conditions can create
a chemical fallout.
Airborne pollutants can fall upon and
attack painted surfaces on your vehicle.
This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched
into the paint surface.
Although no defect in the paint job
causes this, Oldsmobile will repair, at
no charge to the owner, the surfaces of
new vehicles damaged by this fallout
condition within 12 months or 12,000
miles (20
000 ltm) of purchase,
whichever comes first.

Injector 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.
Headlight 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.
