Leaving Your Vehicle With the
Engine
Running
4 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 (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
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) bqjot-e 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
f1-0111 the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).

10. Use the wrench to
tighten the wheel nuts
firmly in a crisscross
sequence
as shown.
f CAUTiN: '
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become 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.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench
to
100 lb-ft (140 Nom).
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.

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 bra
cz k es.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts
in the
proper sequence to
GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.’’
.e Pedal Travel
See your retailer 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 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.
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 have to have 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.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for
a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to I3 000 km). Any time you notice unusual
wear, rotate your tires as
soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When
It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
lrniform wear for all tires on the vehicle. The first
rotation is the most important. See ”Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your
tires, always use the correct rotation
pattern shown here.
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque’‘ in
the Index.
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
“Changing a Flat Tire” in the Index.)
