1995 OLDSMOBILE AURORA Owners Manual

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.
Sometimes, as when you're driving
on snow or ice, it's
easy to ask n~ore
of those control systems than the tires
and road can provide. That means
~OLI can lose control
of your vehicle.
Braking
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
rem-tion time.
Average remtio/1 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
lnph ( 100 km/h) 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
tread; and the condition
of your brakes.

Avoid needless heavy braking. Some people drive in
spurts -- heavy acceleration followed by heavy braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear
out much fdster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot
of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But
you will use it when you brake. Once the power assist is
used up,
it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your Aurora has an advanced electronic braking system
that
will help prevent a braking skid.
ANT’- (I)
LOCK
This light on the
instrument panel
will
come on briefly 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 there’s a problem with the anti-lock brake
system, the anti-lock brake system warning light will
stay
on.
See “Anti-Lock Brake System Warning Light“ in the
Index.

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. If one
of the wheels is about to stop rolling, the computer will
separately work 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.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

Remember: Anti-lock doesn't change the time you need
to get your
foot up to the brake pedal. If you get too
close to the vehicle in front of you, you won't have time
to apply your brakes
if that vehicle suddenly slows 01-
stops. Always leave enough 1-0om up ahead to stop. even
though you have anti-lock brakes.
To Use Anti-Lock
Don't pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may hear
a motor or
clicking noise during a hard stop. but this is normal.
Traction Control System
Your vehicle has a traction control system that limits
wheel spin. This is especially useful
in slippery road
conditions. The system operates only
if it senses that one
or both of the front wheels are spinning or beginning to
lose traction. When this happens, the system works the
front brakes and reduces engine power (by shutting off
fuel injectors and managing engine spark) to
limit wheel
spin.
The TRACTION ACTIVE light will come on when
your traction control system
is limiting wheel spin. See
"Traction Control System Active Light"
in the Index.
You may feel the system working, or you may notice
some noise, but this is normal.
If yo~~r vehicle is in
cruise control when the traction control system begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use
it again, you may re-engage the cruise control. (See
"Cruise Control"
in the Index.)
TRACTION
OFF
When the system is on, the TRACTION OFF warning
light
will come on to let you know if there's a problem
with your traction control system. See "Traction Control
System Warning Light"
in the Index. When this warning
light is on, the system
will not limit wheel spin. Adjust
your driving accordingly.

The traction control system automatically comes on
whenever
you start your vehicle. To limit wheel spin,
especially
in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off
if you ever need to. (You
should
turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle”
in the Index.)
I ‘ -I
To turn the system off,
press the TRACTION
CONTROL button on
the center console. The
TRACTION
OFF warning light will come on and
stay on.
If the system is limiting wheel spin when you
press the button,
the system won’t turn off right away. It
will wait until there’s no longer a current need to limit
wheel spin.
You can
turn the system back on at any time by pressing
the button again. The TRACTION
OFF warning light
should go
off.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time.
In many emergencies, steering can help you more
than even the very best braking.

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.
Magnasteer TM
Your vehicle is equipped with GM Magnasteer”, a
steering system that continuously adjusts
the effort you
feel when steering at all vehicle speeds.
It provides ease
when parking yet a firm, solid feel at highway speeds.
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 yo~lr speed. While
you’re
in a curve, speed is the one factor YOLI 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. Unless your traction control
system is on, adding the sudden acceleration can
demand
too much of those places. You can lose control.
What should
Y~LI 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
YOLI’II want to go slower.
If YOLI need to reduce your speed as you approach a
curve, do
it before YOLI enter the curve, while your front
wheels are straight ahead.
Try to adjust YOLI~ 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.

Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over
a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right
in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can't; there isn't room. That's
the time for evasive action
-- steering around the
problem.
Your Aurora can perform very well
in emergencies like
these. First apply your brakes.
It is better to remove as
much speed
as you can from a possible collision. Then
steer around the problem,
to the left or right depending
on the space available.
An emergency like this requires close attention and a
quick decision.
If you are holding the steering wheel at
the recommended
9 and 3 o'clock positions, you can
turn it a full I80 degrees very quickly without removing
either hand.
But you have to act fast, steer quickly, and
just
as quickly straighten the wheel once you have
avoided the object.
The fact that s11ch emergency situations are always
possible
is a good reason to practice defensive driving at
all times and wear safety belts properly.
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 1/4 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel
to go straight down the roadway.

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 making a successful pass, wait for
a better time.
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
(providing the road ahead
is clear). 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.
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.
When it looks 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.
If other cars are lined LIP to pass a slow vehicle, wait
your turn.
But take care that someone isn’t trying to
pass you as you pull out to pass the slow vehicle.
Remember
to glance over your shoulder and check
the blind spot.
