AUTOMATIC OVERDRIVE (0): If your automatic
transaxle has AUTOMATIC OVERDRIVE
(a), this
position is for normal driving.
If you need more power
for passing, and you’re:
Going less than 35 mph (56 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator all
the way down. You’ll shift down to
the next gear and have more power.
NOTICE:
This NOTICE applies only if you have an
automatic overdrive transaxle.
If your vehicle is
so equipped and if it seems to start up rather
slowly, or
if it seems not to shift gears as you go
faster, something may
be wrong with a transaxle
system sensor.
If you drive very far that way,
your vehicle can be damaged.
So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND
(2) when you are driving
less than
35 mph (56 km/h) and AUTOMATIC
OVERDRIVE
(0) for higher speeds. THIRD
(3): This
position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE
(@). Here
are some times you might choose THIRD
(3) instead of
AUTOMATIC OVERDRIVE (@):
0 When driving on hilly, winding roads.
0 When towing a trailer, so there is less shifting
between gears.
0 When going down a steep hill.
SECOND
(2): This position gives you more power but
lower fuel economy.
You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes
off and on.
2-23

NOTICE:
Don’t drive in SECOND (2) for more than
25 miles (41 km), or at speeds over 55 mph
(88 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE
(GO) or
THIRD
(3) as much as possible. Don’t shift into
SECOND
(2) unless you are going slower than
65 mph (105 km/h) or you can damage
your engine.
If you have automatic overdrive,
SECOND (2) will select
either first or second gear depending on vehicle speed. If
your vehicle is slowing, the transaxle will downshift to
first gear at
20 to 25 miles per hour (32 to 40 h/h) for
engine braking.
You may notice some variation in shift
speed in
SECOND (2) when accelerating or braking.
FIRST (1): This position gives you even more power (but
lower
fuel economy) than SECOND (2). You can use it on
very steep hills, or in deep snow or mud. If the selector
lever
is put in FIRST (l), the transaxle won’t shift into
first gear until the vehicle is
going slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against
a
solid object. You can damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into
PARK (P)
to hold your vehicle in position on a hill.
2-24

Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot.
Push down the parking
brake pedal with your left
foot.
If the ignition is on,
the brake system warning
ght will come on.
To release the parking
brake, hold the regular
brake pedal down. Pull the
BRAKE RELEASE lever.
NOTICE:
Driving with the parking brake on can cause
your rear brakes
to overheat. You may have to
replace them, and you could also damage other
parts
of your vehicle.
If you are towing a trailer and are parking on a hill, see
“Towing a Trailer” in t.he Index. That section shows
what to
do first to keep the trailer from moving.
2-28

If the light comes on while you are driving, pull off the
road and stop carefully. You
may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop.
If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
-: CAUTION:
Your brake system may not be working properly
if the brake system warning light is
on. Driving
with the brake system warning light
on can lead
to an accident.
If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If
it stays on after your parking brake is fully
released,
it means you have a brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when
you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light stays on, turn the ignition to
OFF. Or, if the
light comes
on when you’re driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you’re driving, your Oldsmobile
needs service. If the regular brake system warning light
isn’t
on, you still have brakes, but you don’t have
anti-lock brakes.
If the regular brake system warning
light is also on, you don’t have anti-lock brakes and
there’s a problem with your regular brakes. See “Brake
System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn you if there is
a problem.
2-63

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 more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
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 314 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 (1 00 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
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.

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
faster 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 vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
1
If there’s a problem with the
anti-lock brake system, this
warning light will stay on. See “Anti-Lock Brake
System Warning Light” in
the Index.
4-7

1 The anti-lock system can change the brake pressure
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.
You can steer around the obstacle while braking hard.
4-8

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 or always decrease
stopping distance. 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 or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you.
You may feel the system
working, or you may notice some noise, but this is normal.
Enhanced Traction System (If Equipped)
If your vehicle has the optional four-speed automatic
transaxle,
it also has an Enhanced Traction System
(ETS) 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 reduces engine power and may also upshift the
transaxle
to limit wheel spin.
LOW
TRAC
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See “Enhanced
Traction System Active
Light” in the Index.
You
may feel or hear the system
working, but this is normal.
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high
as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in the Index.
4-9

Steering in Emergencies
lull
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
p
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 Oldsmobile can perform very well in emergencies
like these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.) 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.
S
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 180 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 such emergency situations
are always
possible is
a good reason to practice defensive driving at
all times and wear safety belts properly.
