Use
the wrench to tighten the wheel nuts firmly in a criss-cross sequence as
shown. Remove the wheel blocks.
Storing the Jack and Spare Tire
Return the jack, wheel wrench and wheel blocks to the proper location in
your vehicle’s rear area. Secure
the items and replace the jack cover. Put the
flat tire where the spare tire was stored. If you have the underbody carrier:
1. Put the tire on the ground at the rear of the vehicle, with the valve stem
pointed down and to the rear.
2. Pull the retaining bar through the wheel.
3. Put the chisel end of the wheel wrench, on an angle, through the hole in
the rear bumper and into the hoist shaft. Turn the wheel wrench
clockwise until the tire is raised against the underside
of the vehicle.
You will hear two “clicks” when the tire is secure, but pull
on the tire to
make sure.

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.
5-35

Downloaded from www.Manualslib.com manuals search engine NOTICE:
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 (or with
a manual transmission, between FIRST (1) or
SECOND
(2) gear and REVERSE), 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. Or, you can use your
recovery hooks, if your vehicle has them. If you do need to be towed out,
see “Towing Your Vehicle” in the Index.
Using the Recovery Hooks
I
Your vehicle may be equipped with recovery hooks. The recovery hooks\
are
provided at the front
of your vehicle. You may need to use them if you’re
stuck off-road and need
to be pulled to some place where you can continue
driving.

If your vehicle has four-wheel drive, you will have a remote oil filter. There
is a special access door in the steering linkage shield assembly located under
the radiator support. Twist the screw to lock or unlock the door.
Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-18 “C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in
the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
Used oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose of oil by putting it in the trash, pouring
it on the ground, into
sewers, or into streams or bodies of water. Instead, recycle it by taking
it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
Air Cleaner
To remove the rectangular air cleaner filter for the 4.3L (VIN W) engine,
open both clamps and push the rear
of the air cleaner back toward the rear
of the engine compartment to change the filter.

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.
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.

rotating your
tires, always use one of the correct rotation
patterns shown here.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the Certificatioflire 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 Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance. (This applies only to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tire when tested under controlled conditions on a specified government test
course. For example, a tire graded
150 would wear one and a half (1 1/2)
times as well on the government course as a tire graded 100. The relative
performance
of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road characteristics and
climate.
Traction -A, B, C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete.
A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this
tire is based on braking
(straight-ahead) traction tests and does not include cornering (turning)
traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
6-45

Downloaded from www.Manualslib.com manuals search engine Warning: The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation,
or
excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary with respect
to these grades, all such tires meet
General Motors performance standards and have been approved for use on
General Motors vehicles. All passenger type
(P Metric) tires must conform
to Federal safety requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life and best overall performance.
In most cases, you will not need to have your wheels aligned again.
However, if you notice unusual tire wear or your vehicle pulling one way or
the other, the alignment may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need to be
rebalanced
.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted or corroded. If
wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your GM dealer if any of
these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with
new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts for your
vehicle.
