6. Lower the vehicle by turning the jack handle to the
left. Lower the
jack completely.
7. Tighten the wheel
nuts
firmly in a
crisscross sequence
as shown.
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.)
5-34

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.
Don’t
try to put the wheel cover on your compact
spare tire.
It won’t fit. Store the wheel cover in the
trunk until you have the flat tire repaired or replaced.
I NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover
or the spare.
Storing the Flat Tire and Tools
A CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause iqjury.
In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
After you’ve put the compact spare tire on
your vehicle,
you’ll need to store the flat tire in
your trunk. Use the
following procedure to secure the flat tire
in the trunk.

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 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.”
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 apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modem 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 Pontiac has an ACDelco Freedom@ battery.
You never have to add water to one of these. When it’s
time for a
new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.
6-36

After the tires have been rotated, adjust the front and rear inflation pressures as shown on
the Tire-Loading
Information label. Make certain that all wheel nuts are properly tightened. See “Wheel
Nut Torque” in
the Index.
L
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.)
I I
When It’s Time for New Tires
.. I
One way to tell when it’s
time for
new tires is to
check the treadwear
indicators, which will appear when your tires have
only 1/16 inch (1.6 mm) or
less
of tread remaining.
YOU need a new tire if any of the following statements
are true:
0
0
0
0
0
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that can’t be repaired well
because of the size or location
of the damage.
