Anti-Lock Brakes (CONT.)
And this light on the instrument panel
will go on when you start your vehicle.
When you start your vehicle and begin
to drive away you may hear a
momentary motor or clicking noise and
you may even notice that your brake
pedal moves a little while this is going
on. This is the
ABS system testing itself.
If you have your foot on the brake
pedal, this check won’t happen until the
vehicle goes about
4 mph (6 lm/h) or
until you take your foot off the brake
pedal.
You’ll also hear a clicking noise the
next time the vehicle goes about
4 mph
(6 lun/h).
If there’s a problem with the anti-lock
brake system, the anti-lock brake
system warning light will stay on or
flash. See the
Index under Anti-Lock
Brake System Warning Light.
Here’s how anti-lock works. Let’s say
the road is wet. You’re driving safely.
Suddenly an animal jumps out in front
of you.
You slam on the brakes. Here’s what
happens with
ABS.
A computer senses that wheels are
slowing down. The computer separately
works the brakes at each front wheel
and at the rear wheels.
The anti-lock system can change the
brake pressure faster than any driver
could. The computer is programmed to
make the most of available tire and road
conditions.

Disc Brake Wear Indicators

Some driving conditions or climates
may cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean something
is wrong with your brakes.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or
if there
is a rapid increase in pedal travel. This
could be
a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake
stop, your disc brakes adjust for wear.
If
you rarely make a moderate or heavier
stop, then your brakes might not adjust
correctly.
If you drive in that way,
then-very carefully-make a few
moderate brake stops about every
1,000
miles (1 600 km), so your brakes will
adjust properly.

Steering Tips-Driving on Curves
154
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 jaws 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 banlted, 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 apply
the brakes. Both control systems-
steering and braking-have to do their
work where the tires meet the road.
Unless you have four-wheel anti-lock
brakes, adding the hard braking can
demand too much at those places.
You
can lose control.
The same thing can happen if you’re
steering through a sharp curve and you
suddenly accelerate. Those two control
systems-steering and acceleration-
can overwhelm those places where the
tires meet the road and make you lose
control.
What should you do if this ever
happens? Let up on the brake or
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.
When you drive into a curve at night,
it’s harder
to see the road ahead of you
because it bends away from the straight
beams of your lights. This is one good
reason to drive slower.

Off-Road Recovery
You may find sometime that your right
wheels have dropped off the edge of a
road onto the shoulder while you’re
driving.
If the level of the shoulder is only
slightly below the pavement, recovery
should be fairly easy. Ease off the
accelerator and then,
if there is nothing
in the way, steer
so that your vehicle
straddles the edge of the pavement.
You
can turn the steering wheel up to ‘/4
turn until the right front tire contacts
the pavement edge. Then turn your
steering wheel to go straight down the
roadway.
If the shoulder appears to be about four
inches
(100 mm) or more below the
pavement, this difference can cause problems.
If there is not enough room
to pull entirely onto the shoulder and
stop, then follow the same procedures.
But
if the right front tire scrubs against
the side of the pavement, do
not steer
more sharply. With too much steering
angle, the vehicle may jump back onto
the road with
so much steering input
that it crosses over into the oncoming
traffic before you can bring it back
under control. Instead, ease
off again on
the accelerator and steering input,
straddle the pavement once more, then
try again.
Passing
The driver of a vehicle about to pass
another on a two-lane highway waits for
just the right moment, accelerates,
moves around the vehicle ahead, then
goes back into the right lane again.
A
simple maneuver?
Not necessarily! Passing another vehicle
on
a two-lane highway is a potentially
dangerous move, since the passing
vehicle occupies the same lane as
oncoming traffic for several seconds.
A
miscalculation, an error in judgment, or
a brief surrender to frustration or anger
can suddenly put the passing driver face
to face with the worst of all traffic
accidents-the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road,
to the sides, and to crossroads for
situations that might affect your
passing patterns. If you have
any
doubt whatsoever about malting a
successful pass, wait for a better time.
I

Watch for traffic signs, pavement
markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
pass.
A broken center line usually
indicates it’s all right to pass
Never cross
a solid line on your side
of the lane or a double solid line, even
if the road seems empty of
approaching traffic.
If you suspect that the driver of the
vehicle you want to pass isn’t aware
of your presence, tap the horn a
couple of times before passing. Or,
you can use flash-to-pass. See the
Index under Flash-to-Pass.
Do not get too close to the vehicle
you want to pass while you’re
awaiting an opportunity. For one
thing, following too closely reduces
your area of vision, especially if you’re
following a larger vehicle.
Also, you
won’t have adequate space if the
vehicle ahead suddenly slows or stops.
Keep back a reasonable distance.
I (providing the road ahead is clear).
When it loolts like a chance to pass is
coming up, start to accelerate but stay
in the right lane and don’t get too
close. Time your move
so you will be
increasing speed as the time comes to
move into the other lane. If the way is
clear to pass, you
will have a “running
start” that more than makes up for
the distance you would lose by
dropping back. And if something
happens to cause you to cancel your
pass, you need only slow down and
drop back again and wait for another
opportunity.

cause the tires to slide. You may not
realize the surface is slippery until your
vehicle is skidding. 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.
If you have the anti-lock braking
system, remember: It helps avoid only
the braking skid.
If you do not have
anti-lock, then in a braking skid (where
the wheels are no longer rolling),
release enough pressure on the brakes
to get the wheels rolling again. This
restores steering control. Push the
brake pedal down steadily when you
have to stop suddenly. As long as the
wheels are rolling, you will have
steering control. Steer the way you
want to go.

Driving at Night
Night driving is more dangerous than
day driving. One reason is that some
drivers are likely to be impaired-
by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively. Remember, this is
the most dangerous time.
Don’t drink and drive. (See the Index
under Drunken Driving for more on
this problem.)
Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can’t see as well, you may
need to slow down and keep more
space between you and other vehicles.
It’s hard to tell how fast the vehicle
ahead is going just by looking at its

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.

Freeway Driving
Mile for mile, freeways (also called
thruways, parkways, expressways,
turnpikes, or superhighways) are the
safest
of all roads. But they have their
own special rules.
The most important advice on freeway
driving is: Keep up with traffic and keep
to the right. Drive at the same speed
most of the other drivers are driving.
Too-fast or too-slow driving breaks a
smooth traffic flow. Treat the left lane
on a freeway as a passing lane.
Entering the Freeway
At the entrance there is usually a ramp
that leads to the freeway.
If you have a
clear view of the freeway as you drive
along the entrance ramp, you should
begin to check traffic. Try to determine
where you expect to blend with the
flow. If traffic is light, you may have no
problem. But if it is heavy, find a gap as
you move along the entering lane and
time your approach. Try to merge into
the gap at close to the prevailing speed.
Switch on your turn signal, check your
rearview mirrors as you move along,
and glance over your shoulder as often
as necessary. Try to blend smoothly
with the traffic flow.
Driving on the Freeway
Once you are on the freeway, adjust
your speed to the posted limit or to the
prevailing rate
if it’s slower. Stay in the
right lane unless you want to pass. If
you are on a two-lane freeway, treat the
right lane as the slow lane and the left
lane as the passing lane.
If you are on a three-lane freeway, treat
the right lane as the slower-speed
through lane, the middle lane as the
higher-speed through lane, and the left
lane as the passing lane.
Before changing lanes, check your
rearview mirrors. Then use your turn
signal. Just before you leave the lane,
glance quickly over your shoulder to
make sure there isn’t another vehicle in
your “blind” spot.

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:

Run your engine only as long as you
must. This saves fuel. When you run
the engine, male it go a little faster
than just idle. That is, push the
accelerator slightly. This
uses less fuel
for the heat that you get and it keeps
the battery charged. You will need a
well-charged battery to restart the
vehicle and possibly for signaling later
on with your headlights. Let the
heater run for a while.
Then, shut the engine
off and close
the window almost all the way to
preserve the heat. Start the engine
again and repeat this only when you
feel really uncomfortable from the
cold. But do it as little
as possible.
Preserve the fuel as long as you can.
To help keep warm, you can get out of
the vehicle and do some fairly
vigorous exercises every half-hour or
so until help comes.
