Downloaded from www.Manualslib.com manuals search engine 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 pressing the button
on a console shift lever. If you can, it means that the
shift lever wasn’t fully locked into PARK
(P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your
transmission into PARK (P) properly, the weight of
the
vehicle may put too much force on the parking pawl in
the transmission. 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 transmission,
so you can pull the shift
lever out of PARK
(P).
Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock.
You have to fully apply your regular brake before you
can shift from PARK (P) when the ignition is in the
RUN position. See “Automatic Transmission Operation”
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 (you must
press the shift lever button if you have the console
shift lever).
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 vehicle and then shift to the drive gear
5. Have the vehicle fixed as soon as you can.

wheel nuts can cause the wheel to become loose

Be sure to use the correct wheel nuts.

Improperly tightened wheel nuts can lead to

To avoid

Downloaded from www.Manualslib.com manuals search engine Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does
not mean something is wrong with
your brakes.
Free movement
of brake calipers and properly torqued
wheel nuts are necessary
to help prevent brake
pulsation. When tires
are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque
wheel nuts in the proper sequence to GM Specifications.
Your rear drum brakes don’t have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
should be removed and inspected each time the tires are
removed for rotation or changing. When
you have the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.

Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase
in pedal
travel. This could
be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes
a few times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be of top quality and work well
together if the vehicle is to have really good braking.
Vehicles we design and
test have top-quality GM brake
parts in them, as your vehicle does when it is new. When
you replace parts of your braking system -- for example,
when your brake linings wear down and
you have to
have new ones put in
-- be sure you get new genuine
GM replacement parts.
If you don’t, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change
-- for the
worse. The braking performance you’ve come to expect
can change in many other ways if someone puts in the
wrong replacement brake parts.

Rust or dirt on
a wheel, or on .the parts to Which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use
a scraper or wire brush later, if you
need to, to get all the rust or dirt
off. (See
