Make sure the shift lever is fully into PARK (P) range
before starting the engine. Your Buick has
a
brake-transaxle shift interlock. You must fully apply
your regular brakes before you can shift from PARK
(P)
when the ignition is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever by pushing it
all the way into PARK (P) while keeping the brake pedal
pushed down. See “Shifting Out of PARK
(P)” in
the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
_____~ ~~ ~~ ~
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transaxle. Shift to
REVERSE (R) only after your vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see
“Stuck:
In Sand, Mud, Ice or Snow” in the Index.
NEUTRAL (N): In this position, your engine
doesn’t connect with the wheels.
To restart when you’re
already moving, use NEUTRAL
(N) only. Also, use
NEUTRAL
(N) when your vehicle is being towed.
Shifting out of
PARK (P) or NEUTRAL (N) while
your engine
is “racing” (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don’t shift out
of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn’t covered by your warranty.

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.
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
(@) 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.
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
shift lever is put in
FIRST (1)’ 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 could 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.

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.
A warning chime will sound if the parking brake is set,
the ignition is
on and the shift lever is not in PARK (P)
or NEUTRAL (N).
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.
To release the parking brake, hold the regular brake
pedal down with your right foot and push
the parking
brake pedal with your left foot. When you lift your left
foot, the parking brake pedal will follow it to the
released position.
If you are towing a trailer and are parking on any hill,
see “Towing a Trailer’’ in the Index. That section shows
what to
do first to keep the trailer from moving.

Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.”
To
prevent torque lock, set the parking brake and then shift
into PARK
(P) properly before you leave the driver’s
seat.
To find out how, see “Shifting Into PARK (P)” in
the Index.
When you are ready to drive, move the shift lever out
of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a
little uphill to take some of the
pressure from the parking pawl in the transaxle,
so you
can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Your Buick has a brake-transaxle shift interlock. You
must fully apply your regular brakes before you can
shift from PARK (P) when the ignition is in RUN. See
“Automatic Transaxle Operation” in the Index.
If
you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing
it all the way into PARK (P)
while keeping the brake pedal pushed down. Then move
the shift lever
out of PARK (P).
If
you ever hold the brake pedal down but still can’t
shift
out of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and shift to the drive gear you want.
5. Have the vehicle fixed as soon as you can.

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 or if the
anti-lock brake system warning light is flashing
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
ANTI -
LOCK
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 flashes when you’re driving, you don’t have
anti-lock brakes and there could be
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 closer to the floor. It may take longer to stop.
Have the vehicle towed for service. (See “Towing Your
Vehicle”
in the Index.)

ON:
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock brake system warning light flashing can lead
to an
accident. After you’ve pulled off the road and
stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. Or, if the light comes on and stays 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 Buick needs service, If the
light is
on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
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.

Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay
on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active light also comes
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
there to tell you when the system is active.

Control of a Vehicle Braking
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 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.
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. 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 314
of a second, a vehicle
moving at
60 mph (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
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 bralung. 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.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light” in the Index.
