air distribution and fan speed:
1. Set the temperature you want with
the

Road Signs
The road signs you see everywhere are
coded by color, shape and symbols. It's
a good idea to lmow these codes so that
you can quickly grasp the basic meaning
or intent of the sign even before you
have a chance to read it.
STOP
DO NOT
ENTER WRONG
WAY
Color of Road Signs
Red means Stop. It may also indicate
that some movement is not allowed.
Examples are
Do Not Enter, Wrong
Way,
or No Parking.
Green is used to guide the driver.
Green signs may indicate upcoming
freeway exits or show the direction you
should turn to reach a particular place.
RR ADVANCE NARROW NO PASSING
CROSSING BRIDGE ZONE
Yellow indicates a general warning.
Slow down and be careful when you see
a yellow sign. It may signal a railroad
crossing ahead, a no passing zone, or
some other potentially dangerous
situation. Likewise, a yellow solid line
painted on the road means
Don't
Cross.
Blue signs with white letters show
motorists' services.

Night Vision
No one can see as well at night as in the
daytime. But as we get older these
differences increase.
A 50-year-old
driver may require at least twice as
much light to see the same thing at
night as a 20-year-old.
What you do in the daytime can also
affect your night vision. For example, if
you spend the day in bright sunshine
you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to
night.
But if you’re driving, don’t wear
sunglasses at night. They may cut down
on glare from headlights, but they
also
make a lot of things invisible that
should remain visible-such as parked
cars, obstacles, pedestrians, or even
trains blocking railway crossings. You
may want to put
on your sunglasses
after you have pulled into a brightly- lighted service
or refreshment area.
Eyes shielded
from that glare may
adjust more quickly to darkness back
on the road. But be sure to remove your
sunglasses before you leave the service
area.
You
can be temporarily blinded by
approaching lights. It
can take a second
or two, or even several seconds, for
your eyes to readjust to the dark. When
you are faced with severe glare (as from
a driver who doesn’t lower the high
beams, or a vehicle with misaimed
headlights), slow down a little. Avoid
staring directly into the approaching
lights. If there is a line of opposing
traffic, make occasional glances over the
line of headlights
to make certain that
one of the vehicles isn’t starting to
move into your lane. Once you are past
the bright lights, give your eyes time to
readjust before resuming speed.
High Beams
If the vehicle approaching you has its
high beams
on, signal by flicking yours
to high and then back to low beam. This
is the usual signal to lower the
headlight beams. If the other driver still
doesn’t lower the beams, resist the
temptation to put your high beams
on.
This only makes two half-blinded
drivers.
On a freeway, use your high beams only
in remote areas where you won’t impair
approaching drivers. In some places,
like cities, using high beams is illegal.
When you follow another vehicle on a
freeway or highway, use low beams.
True, most vehicles now have day-night
mirrors that enable the driver to reduce
glare. But outside mirrors are not of this
type and high beams from behind can
bother the driver ahead.

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?

7. Don’t let the other end touch metal.
Connect it to the positive

terminal of the good battery.
Use a remote positive
(+) terminal if
the vehicle has one.
8. Now connect the black negative
(-) cable to the good battery’s
negative
(-) terminal.
Don’t let the other end touch anything
until the next step. The other end of the
negative cable
doesn’t go to the dead
battery. It goes to a heavy unpainted
metal part on the engine
of the vehicle
with the dead battery.
9. Attach the cable at least 18 inches
(45 cm) away from the dead battery,
but not near engine parts that move.
The electrical connection is just as
good there, but the chance
of sparks
getting back to the battery is much
less.
IO. Now start the vehicle with the good
battery and run the engine for a
while.
11. Try to start the vehicle with the
dead battery.
If it won’t start after a few tries, it
probably needs service.
12. Remove the cables in reverse order
to prevent electrical shorting. Take
care that they don’t touch each
other or
any metal.

Towing Your Oldsmobile
Try to have a GM dealer or a
professional towing service tow your
Oldsmobile. The
usual towing
equipment
is:
(A) Sling-type tow truck
(B) Wheel-lift tow truck
(C) Car carrier
If your vehicle .has been changed or
modified since it was factory-new by
adding aftermarket items like fog lamps,
aero skirting, or special tires and
wheels, these instructions and
illustrations may not be correct.
Before you do anything, turn on the
hazard warning flashers. When
you
call, tell the towing service:

When the towing service arrives, let the
tow operator know that this manual
contains detailed towing instructions
and illustrations. The operator may

To help avoid injury to you
or others:
Never let passengers ride in a
vehicle that is being towed.
Never tow faster than safe or
posted speeds.
Never tow with damaged parts
not fully secured.
Never get under your vehicle after
it has been lifted by the tow
truck.
Always use separate safety chains
on each side when towing a
vehicle.
Never use “J” hooks. Use T-

Towing Your Oldsmobile (CONTJ
When your vehicle is being towed, have
the ignition key
off. The steering wheel
should be clamped in
a straight-ahead
position, with
a clamping device
designed for towing service. Do not use
the vehicle’s steering column lock for
this. The transaxle should be in
N (Neutral), and the parking brake
released.
Don’t have your vehicle towed on the
front wheels, unless you must. If the
vehicle must be towed on the front
wheels, don’t go more than
35 mph
(56 km/h) or farther than 50 miles
(80 lun) or your transaxle will be
damaged.
If these limits must be
exceeded, then the front wheels have to
be supported on a dolly. A vehicle can fall from a
car
secured. This can cause a collision,
serious personal injury and vehicle
damage. The vehicle should be
tightly secured with chains or steel
cables before it is transported.
Don’t use substitutes (ropes,
leather straps, canvas webbing,
etc.) that can be cut by sharp edges
underneath the towed vehicle.

Engine Overheating (CONTJ
If No Steam is Coming from Your
Engine:
If you get the overheat warning but see
or hear no steam, the problem may not
be too serious. Sometimes the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.

If you get the overheat warning with no
sign of steam, try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the
highest fan speed and open the
window as necessary.
3. Try to keep your engine under load
(in
a drive gear where the engine
runs slower).
If you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for ab& ten minutes. If
the warning doesn't come back on, you
can drive normally.
If the warning continues, pull over,
stop, and, park your vehicle right away.
f there's still no sign of steam, you can
dle the engine for two or three minutes
