TPM Sensor Identication Codes
Each TPM sensor has a unique identication code. Any
time you replace one or more of the TPM sensors, the
identication codes will need to be matched to the new
tire/wheel position. Each tire/wheel position is matched,
to a sensor, by increasing or decreasing the tire’s air
pressure. The sensors are matched, to the tire/wheel
positions, in the following order: left front (LF), right
front (RF), right rear (RR), and left rear (LR).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall, to match all four
tire/wheel positions. If it takes longer than one minute,
to match the rst tire and wheel, or more than
ve minutes to match all four tire and wheel positions
the matching process stops and you will need to
start over.
The TPM matching process is outlined below:
1. Set the Parking brake.
2. Turn the ignition switch to ON with the engine off.
3. Using the Remote Keyless Entry (RKE) transmitter,
lock and unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the RKE transmitter. A single horn chirp
will sound, indicating that the TPM system is ready,
and the sensor matching process can begin.
5. Start with the left (driver’s side) front tire.6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, conrms that the
sensor identication code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
7. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 6.
8. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 6.
9. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming double horn chirp, for
the left rear tire, exit the matching process by
turning the ignition switch to OFF.
11. Set all four tires to the recommended air pressure
level as indicated on the tire and loading information
label.
12. Put the valve caps back on the valve stems.
The TPM system will not function properly if one or
more of the TPM sensors are missing or inoperable.
If the system detects a missing or inoperable sensor
an error message of several dashes–––will be
shown on the message center display.

{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools
and procedures aren’t used you or others
could be injured and your vehicle could be
damaged. Always be sure the proper tools
and procedures, as described in the service
manual, are used.
To order a service manual seeService Publications
Ordering Information on page 7-11.
Changing a Flat Tire (CTS)
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place.
Turn on your hazard warning ashers.
{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 an automatic transmission shift lever
in PARK (P), or shift a manual transmission
to FIRST (1) or REVERSE (R).
3. Turn off the engine and do not restart while
the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
Put the wheel 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.
5-76

When you have a at tire, use the following example as
a guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
the jack and change a tire.Removing the Spare Tire and
Tools (CTS)
The equipment you will need is in the trunk.
To gain access to the spare tire and jacking equipment,
do the following:
1. Turn the center nut on
the compact spare tire
cover counterclockwise
to remove it. Then
remove the cover.
5-77

2. Turn the nut holding the jack counterclockwise and
remove it. Then remove the jack and wheel wrench.
3. Remove the compact spare tire. SeeCompact
Spare Tire (CTS) on page 5-85for more
information about the compact spare tire.4. The tools you will be using next include the jack (A)
and the wheel wrench (B).

Removing the Flat Tire and
Installing the Spare Tire (CTS)
If your vehicle has wheel covers, use the at end of the
wheel wrench to remove the covers. Turn the wheel
wrench clockwise to gently pry off the wheel cover.
Be careful not to scratch the aluminum wheel edge and
do not try to remove the wheel cover with your hands.If your vehicle has wheel nut caps, turn the wheel
wrench counterclockwise to remove the caps.
5-79

Once the wheel cover and wheel nut caps have been
removed, use the following steps to remove the at tire
and install the spare tire.
1. Place the wheel wrench (A) securely over the wheel
nut (B). Turn the wheel wrench counterclockwise to
loosen all the wheel nuts. Do not remove them yet.2. Find the jacking location using the diagram above
and corresponding hoisting notches located in the
plastic molding. The notches in the plastic molding
are marked with a triangle shape to help you
nd them.
The front location (A) is about 14 inches (35.6 cm)
from the rear edge of the front wheel well, and
the rear location (B) is about 7 inches (17.8 cm)
from the front edge of the rear wheel well.

{CAUTION:
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.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.
3. Attach the wheel wrench to the jack.
4. Turn the wheel wrench counterclockwise to lower
the jack lift head until the jack ts under the
vehicle.5. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into
the metal ange located behind the triangle on
the plastic molding as shown.
6. Put the compact spare tire near you.
7. Raise the vehicle by turning the wheel wrench

ground for the compact spare tire to t under
the vehicle.
5-81

8. Remove all the wheel nuts and take off the at 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.
9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.10. Place the compact spare tire on the wheel-mounting
surface.
{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.
11. Put the wheel nuts
back on with the
rounded end of the
nuts toward the wheel.
Tighten each wheel
nut by turning it
clockwise with your
hand until the wheel
is held against
the hub.
5-82

12. Lower the vehicle by turning the wheel 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 specication. SeeCapacities
and Specifications on page 5-107for wheel
nut torque specication.
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 specication. SeeCapacities
and Specifications on page 5-107for the wheel
nut torque specication.

Power Windows and Other Power
Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is xed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating. If a fuse blows, see your dealer
for service immediately.
If you ever have a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the
same amperage. Pick some feature of your vehicle that
you can get along without — like the radio or cigarette
lighter — and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The fuses are located in three fuse blocks, one located
in the engine compartment on the passenger’s side
and the other two under the rear seat.
Underhood Fuse Block
The underhood fuse block is located in the engine
compartment on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12
for more information on location.
