Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause injury. In a sudden stop
or collision, loose
equipment could strike someone. Store
all these
in the proper place.
I. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed down.
2. Pull the retaining bar through the center of the
wheel, making sure it
is properly attached.

the
hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will hear two “clicks”
when the tire is up all the
way. Try
to move the tire with your hands to make
sure
it is securely in place.
Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking’’ can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transmission or other parts
of the
vehicle can overheat. That
could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.

Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.

For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. Then shift back
and forth between REVERSE (R) and
a forward gear,
spinning the wheels as little as possible. Release
the
accelerator pedal while you shift, and press lightly on
the accelerator pedal when the transmission is in gear. If
that doesn’t get
you out after a few tries, you may need
to be towed out. If you do need to be towed out, see
“Towing Your Vehicle”
in the Index.

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
or Drake 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
brake linings inspected. Also, the rear brake drums 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.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, 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. If your vehicle has dual rear wheels,
also see “Dual Tire Operation’’ later in this section.
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 “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
I FRT FRT
If your vehicle has single rear wheels, always use one of
the correct rotation patterns shown here when rotating
your tires.
II
If your vehicle has dual rear wheels, always use one of
the correct rotation patterns shown here when rotating
your tires.
When you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined
up.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificationmire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.

Downloaded from www.Manualslib.com manuals search engine A CAUTION: I
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.) When
It’s Time
for New Tires
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.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following statements
are true:
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.
0 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.

To
find out what kind and size of tires you need, look at
the Certificatioflire label.
When
the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after
100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper torque, see “Wheel
,Nut Torque” in the Index.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
If you’re going to be doing a lot of driving on
high-crown roads, you can reduce tire wear by adding
5 psi (35 kPa) to the tire pressure in the outer tires. Be
sure to return to the recommended pressures when no
longer driving under those conditions. See “Changing a
Flat Tire” in the Index for more information. The tires installed on your
vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
11 you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch
fire.
You or others could be injured. Be sure all
tires (including the spare) are properly inflated.
