2000 Oldsmobile Silhouette brake

2-44
AUTOMATIC OVERDRIVE (D): This position is for
normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle 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 (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer (so there is less shifting
between gears).

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.

2-45
NOTICE:
Don't drive in SECOND (2) for more than 25 miles
(40 km), or at speeds over 55 mph (90 km/h), or
you can damage your transaxle. Use THIRD (3)
or AUTOMATIC OVERDRIVE (D) 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.
NOTICE:
If your vehicle 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
(55 km/h) and THIRD (3) for higher speeds.
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 (1), the transaxle won't
downshift into first gear until the vehicle is going
slow 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.

2-46
Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot
and push down on the
parking brake pedal with
your left foot.
If the ignition is on, the brake system warning light will
come on. See ªBrake System Warning Lightº in
the Index.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 released 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,
see ªTowing a Trailerº in the Index. That section shows
what to do first to keep the trailer from moving.

2-47
Shifting Into PARK (P)
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle won't move, even
when you're on fairly level ground, use the steps
that follow. If you're pulling a trailer, see
ªTowing a Trailerº in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.
2. Move the shift lever into PARK (P) like this:

Pull the lever toward you.

2-48

Move the lever up as far as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).

2-49
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 ªtorque lock.º
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 ªShifting Into
PARK (P)º 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 vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P), when the
ignition is in RUN.
As you step on the brake pedal, while in PARK (P),
you may hear a click from the solenoid of the system.
This ensures that the system is operating properly.
See ªAutomatic Transaxle Operationº in the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you ever
hold the brake pedal down but still can't shift out of
PARK (P), try this:
1. Turn the ignition 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 then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

Running Your Engine While
You're Parked
It's better not to park with the engine running. But if
ever you have to, here are some things to know.
CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
(See ªBlizzardº in the Index.)
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.

2-58 Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/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 mph (40 km/h).
When you apply your brakes, the cruise
control disengages.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So, don't
use your cruise control on winding roads or
in heavy traffic.

Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Don't use cruise
control on slippery roads.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. (See ªTraction
Control Systemº in the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back on.
Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
