4. Open both hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each battery.
A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there.
If it is low, add water to take
care of that first.
If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged
too.
Before you connect the cables, here are some basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect positive (+) to
negative
(-) or you’ll get a short that would damage
the battery and maybe other parts
too.
6. Connect the red
positive
(+) cable to
the positive
(+) terminal
of the vehicle with the

If your vehicle is certified to meet California Emission
Standards (indicated
on the underhood tune-up label), it
is designed to operate
on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp
on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return
to your
authorized Oldsmobile retailer for diagnosis to
determine the cause of failure. In the event
it is
determined that the cause
of the condition is the type of-
fuels used, repairs may not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return
to your
authorized Oldsmobile retailer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should
not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines may
be available in your area to help clean the air. General
Motors recommends that you use these gasolines
if
they comply with the specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. 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.

Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood to relieve pressure on the
hood prop.
Remove the hood prop from the slot in the hood and
return the prop to its retainer.
Then just pull the hood down firmly to close. It will latch when dropped from
10 to 12 inches (25 to 30 cm)
without pressing on 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.
The oil dipstick is a
yellow ring.
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.
-
Checking 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 down, and check the level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need
to add some oil. But you must use the right kind. This
part explains what kind
of oil to use. For crankcase
capacity, see “Capacities and Specifications” in
the Index.

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions,
the fluid and filter do not require changing.
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 your Oldsmobile retail
facility Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
I NOTICE:
- ~~
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts
or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F
(82°C to
93°C).
ProCarManuals.com

Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), drive the
vehicle in THIRD
(3) until the engine temperature gage
moves and then remains steady for
10 minutes. Then
follow the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine off and
is used
only
as a reference. Let the engine run at idle for
five minutes
if outside temperatures are 50°F (10°C)
or more. If it's colder than 50°F (lO"C), you may have
to idle the engine longer. Should the fluid level be low
during a cold check, you must perform a hot check
before adding fluid. This will give
you a more accurate
reading of
the fluid level.
Checking the Fluid Hot or Cold
0 Park your vehicle on a level place. Keep the
engine running.
0 With the parking brake applied, place the shift lever
in PARK
(P).
0 With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in PARK (P).
Let the engine run at idle for three minutes or more.

Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then pull out the dipstick and
wipe it with
a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be
in the COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the
way; then flip the handle
down to lock the dipstick in place.

Rear Axle What to Use
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level
to the bottom of the filler plug hole. Refer to the Maintenance
Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant
is designed to remain in your
vehicle for
S years or 100,000 miles (1 66 000 km),
whichever occurs first.
The following explains your cooling system and
how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A SO/SO mixture of water and the proper coolant for
your Oldsmobile
will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
ProCarManuals.com

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The repair
cost wouldn’t be covered by your warranty. Too
much water in the mix can freeze and crack the
engine, radiator, heater core and other parts.
If you have to add coolant more than four times a year,
have
your retailer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
imnrove the system. These can be harmful.
Checking Coolant
When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the
level should be
up to FULL HOT, or a little higher.
