Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning flashers.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
CAUTION: (Continued)
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.

Removing the Flat Tire and
Installing the Spare Tire
1. If your vehicle has a wheel cover or hubcap that has
plastic wheel nut caps, loosen the plastic nut caps.
You may need to use the wheel wrench to loosen
them. Do not pry off wheel covers or center caps that
have plastic wheel nut caps.
2. Remove the wheel cover or center cap from the
wheel to find the wheel nuts.If your vehicle has a wheel cover or hubcap without
plastic wheel nut caps, gently pry on the edge of the
plastic wheel trim to remove it from the wheel to find
the wheel nuts.
3. Use the wrench to loosen all the wheel nuts. Don’t
remove them yet.

6. Raise the vehicle by turning the wrench clockwise.
Raise the vehicle far enough off the ground so
there is enough room for the compact spare tire to
fit underneath the wheel well.
7. Remove all of the wheel nuts.
8. Remove the flat tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the 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
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.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.

12. Lower the vehicle by turning the wrench
counterclockwise. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come 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 the
proper torque speci cation. SeeCapacities
and Specifications on page 5-85for wheel nut
torque speci cation.
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
speci cation. SeeCapacities and Specifications on
page 5-85for the wheel nut torque speci cation.
