Forward Gears
(Automatic Overdrive):
If your automatic transaxle has
automatic overdrive, this position is for
normal driving. If you need more power
for passing, and you’re:
Going less than about 35 mph (56
km/h), push your accelerator pedal
about halfway down.
Going about 35 mph (56 Itm/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 the
3800 V6 engine and the
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
2 (Second Gear) when you are
drivin less than
35 mph (56 ltm/h)
and
d D (Overdrive) for higher
speeds.
D (Third Gear): If your automatic
transaxle does not have Overdrive, this
position is for normal driving, at all
speeds, in most street and highway
situations.
If your automatic transaxle has
Overdrive,
D is like m, but you never
go into Overdrive. Here are some times
you might choose
D instead of m:
When driving on hilly, winding roads.
When towing a trailer, so there is less
When going down a steep hill.
2 (Second Gear): This position gives
you more power but lower fuel
economy. You can use

help control your speed as you go down
steep mountain roads, but then you

NOTICE:
Don’t drive in 2 (Second Gear) for
more than
5 miles (8 ltm), or at
speeds over
55 mph (88 ltm/h), or
you can damage your transaxle.
Use
D (m or D if your vehicle has
Overdrive) as much as possible.
Don’t shift into
2 unless you are
going slower than
65 mph (105
ltm/h), or you can damage your
engine.

even more power (but lower fuel
economy) than

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 could
damage your transaxle. Also,
if you
stop when going uphill, don’t hold
your vehicle there with only the

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
light will come
on. See the Index under
Brake System Warning Light.
To Release the Parking Brake:
Hold the regular brake pedal down with
your right foot while you push down on
the parking brake pedal with your left
foot. (To release the tension on the
parking brake cable, you will need to
apply about the same amount of
pressure to the parking brake pedal as
you did when you set the parking
brake.) When you remove your foot from
the parking brake pedal, it will pop
up to the release position.
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
Any Hill:

That section shows what to do first to
keep the trailer from moving.

I Cruise Control (OPTION)
With cruise control, you can maintain a
speed of about
25 mph (40 lun/h) or
more without keeping your foot on the
accelerator.
This can really help on long
trips.
Cruise control does not work at speeds
below about
25 rnph (40 ltm/h).
When you apply your brakes, the cruise
control shuts
off.
To Sef Cruise Control

Anti-Lock Brake System Warning
Light
With anti-lock, this light will go on
when you start your engine and it will
stay on for three seconds. That’s
normal. If the light doesn’t come on,
have it fixed
so it will be ready to warn
you if there is a problem.
If the light flashes when you’re driving,
you don’t have anti-lock brakes and
there’s a problem with your regular
brakes. Pull off the road and stop
carefully.
You may notice that the pedal
is harder to push. Or, the pedal may go

stop. Have the vehicle towed for

when your traction control system
limits wheel spin for less than four
seconds. Otherwise, the light will go out

Traction Control System Warning
Light (OPTION: 3800 V6 ENGINE)
The TCS (Traction Control System)
warning light may come on if your
brakes overheat. When this warning
light is on, the system will not limit
wheel spin. Adjust your driving
accordingly. This means that your
traction control system has temporarily
shut down to allow the brakes to cool.
(The traction control system will not
shut down while it is actively
controlling wheel spin.) When the
brakes have cooled down, the
TCS
warning light will go off.
If the TCS warning light comes on and
stays on for an extended period of time,
your vehicle needs service.

know. Medical research shows that
alcohol in
a person’s system can make
crash injuries worse. That’s especially
true for brain, spinal cord and heart
injuries. That means that if anyone who
has been drinking
- driver or
passenger
- is in a crash, the chance of
being killed or permanently disabled is
higher than if that person had not been
drinking. And we’ve already seen that
the chance
of a crash itself is higher for
drinking drivers. I 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.
I Braking
Braking action involves perception
time
and reaction time.
First, you have to decide to push on the
ProCarManuals.com

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
% of a second, a
vehicle moving at
60 mph (100 kwh)
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; 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 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 Oldsmobile has an advanced
electronic braking system that will help
prevent skidding.

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. of
you.
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 or stops. Always
leave enough room 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 feel the system
working, or you may notice some noise,
but this is normal.
