Torque Lock
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) on page 2-25.
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 transmission,
so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See
Automatic Transmission
Operation
on page 2-22.
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 press
the shift lever button and 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 key to LOCK.
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
you want.
5. Have the vehicle fixed as soon as possible.

Brake Pedal Travel
The brake wear warning sound means that
soon your brakes won’t work well. That could
lead to an accident. When you hear the brake
wear warning sound, have your vehicle
serviced.
Notice: Continuing to drive with worn-out brake
pads could result
in costly brake repair.
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.
Properly torqued wheel nuts are necessary
to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence
to GM torque specifications.
Brake linings should always be replaced as complete
axle sets.
See
Brake System Inspection on page 6-16.
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.
Replacing Brake System Parts
The braking system on a 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. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts
of your braking
system
- for example, when your brake linings
wear down and you need new ones put in
- be sure
you get new approved 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.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Part A: Scheduled
Maintenance Services,” in Section
6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificationnire label. Make certain that
all wheel nuts
are properly tightened. See “Wheel
Nut Torque”
under
Capacities and Specifications on page 5-93.
Rust c. dirt or. - 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 “Changing a Flat
Tire” in the Index.

12. Use the wheel wrench
to tighten the wheel
nuts firmly in
a
crisscross sequence as
shown.
c
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come
off. This could lead to an
accident. Be sure to use the correct wheel nuts.
If you have to replace them, be sure to
get new GM original equipment wheel nuts.
I
CAUTION: (Continued) Stop somewhere as soon
as you can and have
the nuts tightened with a torque wrench to the
proper torque specification. See “Capacities
and Specifications”
in the Index for wheel nut
torque specification.
Notice: Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification. See “Capacities and
Specifications”
in the index for the wheel nut torque
specification.
