2001 CHEVROLET IMPALA engine

2-38
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 (40 km), or at speeds over 55 mph
(90 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 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 turn, 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.

2-40
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.
Column Shift
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) like this:

Pull the lever toward you.

2-42
3. Turn the ignition key to OFF.
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 the PARK (P)
position, 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 (or, if you have the
console shift lever, without first pushing the button).
If you can, it means that the shift lever wasn't fully
locked into PARK (P).
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).

2-43
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You must fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in ON. See ªAutomatic Transaxle Operationº
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. Release the
shift lever button if you have a console shift. Then move
the shift lever out of PARK (P), being sure to press the
shift lever button if you have a console shift.
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 ACC.
2. Apply and hold the brake pedal down 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.
Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things
that can burn.

2-44
Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever 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 Exhaust.º
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.

2-45
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 are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.
Horn
Press at or near the horn symbols on your steering wheel
pad to sound the horn.
Tilt Wheel
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can raise the steering wheel
to the highest level to give your legs more room when
you exit and enter the vehicle, or you can lower it so that
you're more comfortable while driving.
To adjust the wheel, hold
the steering wheel and pull
the lever. Move the steering
wheel to a comfortable
level, then release the lever
to lock the wheel into place.

2-70 Programming the HomeLink

Transmitter
Do not use the transmitter with any garage door opener
that does not have the ªstop and reverseº feature. This
includes any garage door opener model manufactured
before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming!
The engine should be turned off while programming the
HomeLink Transmitter. Follow these steps to program
up to three channels:
1. If you have not previously programmed a universal
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (approximately 20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.2. Hold the end of the hand
-held transmitter
approximately one to three inches (three to eight cm)
away from the HomeLink Transmitter making sure
that you can still see the display.
3. Decide which one of the three channels you want to
program. Using both hands, press the hand
-held
transmitter button and the desired button on the
HomeLink Transmitter. Continue to hold both
buttons through Step 4.
4. Hold down both buttons until you see the indicator
light on the HomeLink Transmitter flash, first slowly
then rapidly. The rapid flashing, which could take
up to 90 seconds, indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.
