Storing the Tire
Put the tire on the ground at the rear of the vehicle, with \
the valve stem
pointed down.
Pull the retaining bar through the center of the wheel, making sure
it is
properly attached. Attach the ratchet, with the
UP side facing you, to the
extension.
Put the flat end of the extension on an angle through 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.
Storing the Jacking Equipment
K35r
Return the jack, ratchet, extension and wheel blocks to the proper location in
the rear storage area. Replace all bolts, retainers and wing nuts in the proper
location. Secure the jacking equipment in its proper location and replace the
jack storage cover.

Storing a jack, a tire, or other equipment in the passenger
b compartment of the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone. Store all these\
in
I the proper place.
Compact Spare Tire
Although the compact spare was fully inflated when your vehicle\
was new, it
can lose air after a time. Check the inflation pressure regula\
rly. It should be
60 psi (420 kPa). The compact spare is made to go up to 3,000 miles
(5000 km), so you can finish your trip and have your full-size tire repaired\
or
replaced where you want. Of course, it’s best
to replace your spare with a
full-size tire as soon as you can. Your spare
will last longer and be in good
shape in case you need
it again.
Don’t use your compact spare on some other vehicle.
And don’t mix your compact spare or wheel with other wheels\
or tires. They
won’t fit. Keep your spare and its wheel together.
Tire chains won’t fit your compact spare. Using them will d\
amage your vehicle and destro) “re chc”? too. Don’t use
ti- chair - 3n your compacl
spare.

If You’m Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is to spin your
wheels. The method known as “rocking” can help you get o\
ut when you’re
stuck, but you must use caution.
I CAUTION
A
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.
NOTICE
Spinning your wheels can destroy parts of your vehicle as well as the
tires.
If you spin the wheels too fast while shifting VOUI ;mission bal
and forth, you can destroy your transmissioi
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will clea\
r the area around
your front wheels. Then shift back and forth between
R (Reverse) and a
forward gear, spinning the wheels
as little as possible. Release the
accelerator pedal while you shift, and press lightly on the ac\
celerator 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.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper General Motors Service Manual. It tells you much more a\
bout how to
service your vehicle than this manual can.
To order the proper service
manual, see ‘Service Publications’’ in the Index.
You should keep a record with all parts receipts and list the mil\
eage and the
date .of any service work you perform. See “Maintenance Reco\
rd” in the
Index.
You can be injured
if you try to do service work on a vehicle without
knowing enough about
it.
Be sure you have sufficient knowledge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and other fasteners.
“English” and “metric” fasteners can be easily confus\
ed.
If you
use the wrong fasteners, parts can later break or fall off. You
I could be hurt.

NOTICE I-
Fuel
The 8th digit of your Vehicle Identification Number (VIN) sho\
ws the code letter for your engine. You will find the VIN at the top left of your instrument
panel. (See “Vehicle Identification Number” in the Index.)\

Use regular unleaded gasoline rated at 87 octane or higher. Wi\
th the 4.3L
(Code
W) engine, use premium unleaded gasoline rated at 91 octane or .
higher for high power performance, when towing a trailer or wi\
th a high
payload requirement. But when operating with a light load as a\
normal
condition, you may use middle grade or regular unleaded gasolin\
es.
The gasoline you use should meet specifications ASTM D4814 in the U.S.
and CGSB 3.5-92 in Canada. These fuels should have the proper \
additives,
so you should not have to add anything to the fuel.
In the
U.S. and Canada, it’s easy to be sure you get the right kind o\
f
gasoline (unleaded). You’ll see
UNLEADED right on the pump. And only
unleaded nozzles
will fit into your vehicle’s filler neck.
Be sure the posted octane
is at least 91 for premium, 89 for middle grade
and
87 for regular. If the octane is less than 87, you may get a heavy
knocking noise when you drive. If it’s bad enough,
it can damage your
engine.
