Care of Your Compact Discs
Handle discs carefully. Store them in
their original cases or other protective
cases and away from direct sunlight and
dust. If the surface of a disc is soiled,
dampen
a clean, soft cloth in a mild,
neutral detergent solution and clean it,
wiping from the center to the edge.
Be sure never to touch the signal
surface when handling discs. Pick up
discs by grasping the outer edges .or the
edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand
most car washes without being
damaged. If the mast should ever
become slightly bent, you can straighten
it
out by hand. If the mast is badly bent,
as it might be-
by vandals, you should
replace it.
Check every once in a while to be sure
the mast is still tightened to the fender.
Power Antenna Mast Care
Your power antenna will look its best
and work well if it’s cleaned from time
to time.
To Clean the Antenna Mast:
1. Turn on the ignition and radio to
raise the antenna to full mast
extension.
spirits or equivalent solvent.
2. Dampen a clean cloth with mineral
3. Wipe the cloth over the mast
sections, removing any dirt.

Your Driving and the Road
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 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?
shape? Have you checked
all levels?
the lenses clean?
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?
Wiper Blades: Are they in good

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down. The
coolant level should be at or above
the
COLD mark.
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
- 1
CAUTION I
Heater and radiator hoses,
and other engine parts, can
1;, ;cry 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
I
you drive the vehicle.
I
If there seems to be no leak, check to
see
if the electric engine fan is running.
If the engine is overheating, the fan
should be running.
If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant
Recovery
Tank:
If you haven’t found a problem yet, but
the coolant level isn’t at or above
COLD, add a
50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery
tank.
(See the Index under Engine Coolant
for more information abaut the proper
coolant
mix.)

Retractable Underhood Light
(OPTION)
To Use:
Pull the light away from the base and
attach it to the area
of the vehicle where
you
may be working. A magnet on the
back will hold it in place.
To Retract:
1. Turn the crank clockwise.
2. Slide the light back into its base.
Engine Oil
It’s a good idea to check your engine oil
level 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.
