Voltmeter (ELEcmoNIc CLUSTER)
Your charging system gage will show
the rate of charge when the engine is

Run position), the display measures the
voltage output
of your battery, and will
flash until you turn the ignition to
Start.
The reading will change as the rate of
charge changes (with engine speed,
etc.), but readings between the warning
zones indicate the normal operating
range. Readings in either warning zone
indicate a possible problem with your

serviced immediately. You
also have a warning light.
A box

I Before Leaving on a Long
Tip
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 Oldsmobile 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?

you checked all levels?
Wiper Blades: Are they in good
Fuel, Engine Oil, Other Fluids: Have
Lights: Are they all working? Are the
lenses clean?
Tires: They are vitally important to a
safe, trouble-free trip. Is the tread
good enough for long-distance
driving? Are the tires all inflated to
the recommended pressure?
Weather Forecasts: What’s the
weather outlook along your route?
Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or
whatever.
There is something about an easy
stretch of road with the same scenery, along
with the hum of the tires on the
road, the drone of the engine, and the
rush of the wind against the vehicle that
can make you sleepy. Don’t let it
happen
to you! If it does, your vehicle
can leave the road in
less than a
second, and you could crash and be
injured.
What can you do about highway
hypnosis? First, be aware that it can
happen.
Then here are some tips:
Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road
ahead and to the sides. Check your
mirrors and your instruments
frequently.
If you get sleepy, pull off the road into
a rest, service, or parking area and
take a nap, get some exercise, or both.
For safety, treat drowsiness on the
highway as an emergency.

Your Driving and the Road
Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not, It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift
down, you
might have to use your brakes
so much
that they would get hot and no longer
work well. On
a long uphill grade, shift down and
reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If you are towing a trailer that weighs
more than
3,000 pounds (1 350 kg), it’s
best to drive in
D instead of Overdrive
(or, as you need to, a lower gear). This
will minimize heat build-up and extend
the life of your transmission.
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake and then
shift to
P (Park).
5. Release the regular brakes.
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;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of
the chocks.
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 transmission fluid (don’t
overfill), engine oil, axle lubricant, belt,
cooling system, and brake adjustment.
Each of these is covered in this manual,

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
deposit control additives and
oxygenates, and if they have been
reformulated to reduce vehicle
emissions.
Fuels in Forei’ 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.

also write us at the following
address for advice. Just tell us where
you’re going and give your Vehicle

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.
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
section explains what kind of oil to use.
For crankcase capacity, see
Capacities
G. Specifications in the Index.
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.
~~
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.

Automatic Transmission Fluid
When to Check and Change
4 good time to check your automatic
transmission fluid level is when the
:ngine 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 an Oldsmobile 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 dipstick.
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,
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:
When outside temperatures are abovc

90°F (32°C).
In
heavy traffic - especially in hot
weather.
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).
To Check 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 ( 10°C), drive the
vehicle in
D (3rd Gear) until the engine
temperature gage moves and then
remains steady for ten minutes. Then
follow the hot check procedures.
To Check 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.
