Air Inflator System (Option)
Your vehicle may be equipped with an air inflator. With
it, you can inflate things like air mattresses and
basketballs, and you can
also use it to bring your tires up
to the proper pressure.
The air inflator is located in the rear compartment on the
driver’s side.
To remove the cover, pull the tab on the
cover and pull it
off.
I
The air inflator kit is stored in the glove box. It includes
a 20-foot
(6 m) hose with an air pressure gage and
nozzle adapters.
Inflating something too much can make it
explode, and you or others could be injured. Be
sure to read the inflator instructions, and inflate
any object only to its recommended pressure.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All
three systems have to do their work
at the places where the tires meet the road.
Braking
Braking action involves perception time and reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s
reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part.
So do alcohol, drugs and
frustration. But even in
3/4 of a second, a vehicle
moving at
60 mph ( 100 kmh) travels 66 feet (20 m).
That could be a lot of distance in an emergency,
so
keeping enough space between your vehicle and others
is important.
And,
of course, actual stopping distances vary greatly
with the surface
of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight
of the
vehicle and the amount
of brake force applied.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.

Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of
us is subject to
the same laws of physics when driving on curves. The
traction of the tires against
the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep
the vehicle going
in the same direction. If you’ve ever
tried to steer a vehicle
on wet ice, you’ll understand this.
The traction you can get
in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While you’re
in a curve, speed is the one factor you can control. Suppose you’re steering
through a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too
much of those places.
You can lose control.
What should you do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to
go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based
on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed as you approach a
curve, do
it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed
so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate
until you are out of the curve, and then
accelerate gently into the straightaway.

Loss of Control
Let’s review what driving experts say about what
happens when the
three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek
an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited
to existing conditions, and by not “overdriving”
those conditions. But skids
are always possible.
The three types of skids correspond to your
Oldsmobile’s
three control systems. In the bralung skid,
your wheels aren’t rolling. In the steering or cornering
skid, too much speed or steering in a curve causes tires
to slip and lose cornering force. And in the acceleration
slud, too much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid
if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on
the road. For safety, you’ll
want to slow down and adjust your driving to these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause
the tires to slide.
You may not realize the surface is slippery until your
vehicle is sludding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface”
-- and slow down
when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

You can be temporarily blinded by approaching
headlamps. 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 headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less
of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren’t
even aware
of it.
Driving in Rain and on Wet Roads
1 V A
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good as on dry roads.
And, if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to
go slower and be
cautious if rain starts to fall while
you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving
on dry pavement.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road
is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires do not have much tread or if
the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles
or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
I
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
a
a
a
Turn on your low-beam headlamps -- not just
your parking lamps
-- to help make you more
visible to others.
Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.
Have good tires with proper tread depth. (See “Tires” in the Index.)

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend
to think you are going
slower than you actually are.
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 retail facilities 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?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
0 Lamps: 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?
0 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 CI second, and you could
crash and be injured.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard
on
mountain roads.
0 Know how to go down hills. The most important
thing to know is this:
let your engine do some of the
slowing down. Shift
to a lower gear when you go
down
a steep or long hill.
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope.
I A CAUTION:
~
Coasting d!!!nhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going
down
a hill. You could crash. Always have your
engine running and your vehicle in gear when
you go downhill.
~
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across
the center of the road. Drive at speeds that let
you stay
in your own lane.
0 As you go over the top of a hill, be alert. There could be
something in your lane, like
a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or winding
roads.
Be alert to these and take appropriate action.

Winter Driving
Here are some tips for winter driving:
a Have your Oldsmobile in good shape for winter.
You may want to put winter emergency supplies in
your vehicle. Include
an ice scraper, a small brush or broom,
a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel,
a flashlight, a red cloth and
reflective warning triangles. And, if
you will be driving
under severe conditions, include a small bag of
sand, a
piece
of old carpet or a couple of burlap bags to help
provide traction. Be sure you properly secure these
items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However,
if there is snow or ice between your tires
and the road, you can have a very slippery situation.
You’ll have a lot less traction
or “grip” and will need
to be very careful.

If you have traction control, keep the system on. It will
improve your ability to accelerate when driving on a
slippery road. Even though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System” in
the Index.
If you don’t have traction control, accelerate gently. Try
not to break the gentle traction. If you accelerate too
fast, the drive wheels will spin and polish the surface
under the tires even more.
Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have an anti-lock braking system, you’ll
want to begin stopping sooner than you would on
dry
pavement. See “Anti-Lock” in the Index.

0
Allow greater following distance on any slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the
sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy when the surrounding roads
are clear. If
you see a patch of ice ahead of you, brake before you
are
on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.
What’s
the worst time for this? “Wet ice.” Very cold
snow
or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32°F; 0°C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
