of the wheel bolts. Don’t remove
them
yet.

Position the jack under the vehicle (as shown in step 4)
and raise the jack lift head until it’s firmly set into the
hoisting notch on the vehicle’s fiame, nearest the
flat tire.
Getting under a vehicle when it is jacked up is
dangerous.
If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
NOTICE:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall.
To help avoid a personal
injury and vehicle damage, be sure to
fit the jack
lift head into the proper location before raising
the vehicle.

clockwise. Raise the vehicle far enough
off the
ground for the spare tire to fit under the vehicle.
5. Remove all wheel bolts and take off the flat tire.
6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
A CAUTION:
I
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel
bolts
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 the 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.

bolts firmly
in a
criss-cross sequence
as shown.
1 A CAUTION:
I
Incorrect wheel bolts or improperly tightened
wheel bolts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use
the correct wheel bolts. If you have
to replace them, be sure to get new
GM original
equipment wheel bolts.
Stop somewhere
as soon as you can and have the
bolts tightened with
a torque wrench to 80 lb-ft
(110 Nam).
NOTICE:
Improperly tightened wheel bolts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
bolts in the proper sequence and to the proper
torque specification.

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.
I
L
If you let your tires spin at hig: ;peed, 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 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. You should turn
your traction control system
off. (See “Traction Control
System” in the Index.) 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
Catera”
in the Index.
