Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-38andDIC Warnings and Messages
on page 3-41.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be in ated to the proper pressure.
A Tire and Loading Information label shows the size of
your vehicle’s original equipment tires and the correct
in ation pressure for your vehicle’s tires when they are
cold. SeeLoading Your Vehicle on page 4-23, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 5-56.
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-63andTires on page 5-50.
Notice:Liquid tire sealants could damage the
Tire Pressure Monitor System (TPMS) sensors.
Sensor damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for
the remainder of the ignition cycle. A DIC warning
message is also displayed. The low tire warning light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause the malfunction light and DIC
message to come on are:
The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle’s tires. The DIC message
and TPMS malfunction light should go off once
the TPMS sensor matching process is performed
successfully. See “TPMS Sensor Matching Process”
later in this section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.

Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. SeeBuying New Tires on
page 5-66.
Operating electronic devices or being near
facilities using radio wave frequencies similar
to the TPMS could cause the TPMS sensors to
malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identi cation code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle’s tires, the identi cation codes
need to be matched to the new tire/wheel location.
The sensors are matched, to the tire/wheel locations, in
the following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. When increasing the tire’s pressure, do
not exceed the maximum in ation pressure indicated on
the tire’s sidewall. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match each tire and wheel
position. If it takes longer than two minutes to match any
tire and wheel position, the matching process stops
and you need to start over.

The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter’s LOCK and UNLOCK buttons, at the
same time, for about ve seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner’s sensor is ready to be learned.
5. Remove the valve cap from the tire’s valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals ash one time to con rm the
sensor identi cation code has been matched to
the tire/wheel position.
6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound to
indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS
learn mode, or if communication with the receiver
stops, or if the time limit has expired, turn the
ignition switch to LOCK/OFF and start over
beginning with Step 2.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

If your vehicle has Goodyear Eagle F1-GS1
P245/45R18 size tires, they are directional tires
and must roll in a certain direction for the
best overall performance. The direction is shown
by an arrow on the tire sidewall. Because these
tires are directional, they should be rotated as
shown here. These tires should only be moved
from front to rear and rear to front on the same
side of the vehicle.After the tires have been rotated, adjust the
front and rear in ation pressures as shown
on the Tire and Loading Information label.
SeeInflation - Tire Pressure on page 5-56
andLoading Your Vehicle on page 4-23.
Reset the Tire Pressure monitor System.
SeeTire Pressure Monitor Operation on page 5-59.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-99.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause a crash. When
you change a wheel, remove any rust or
dirt from 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.Directional Tires

When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
in uence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need new tires if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if
your vehicle has one. Multiple conditions affect how fast
this aging takes place, including temperatures, loading
conditions, and in ation pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure
about the need to replace your tires as they get older,
consult the tire manufacturer for more information.

Buying New Tires
GM has developed and matched speci c tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Speci cation
(TPC spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.
GM’s exclusive TPC Spec system considers over a
dozen critical speci cations that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and tire
pressure monitoring performance. GM’s TPC Spec
number is molded onto the tire’s sidewall near the tire
size. If the tires have an all-season tread design,
the TPC spec number will be followed by a MS, for mud
and snow. SeeTire Sidewall Labeling on page 5-52
for additional information.GM recommends replacing tires in sets of four. This is
because uniform tread depth on all tires will help
keep your vehicle performing most like it did when the
tires were new. Replacing less than a full set of tires can
affect the braking and handling performance of your
vehicle. SeeTire Inspection and Rotation on page 5-63
for information on proper tire rotation.
{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes,
brands, or types (radial and bias-belted tires)
the vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes, brands, or types may also cause
damage to your vehicle. Be sure to use the
correct size, brand, and type of tires on your
vehicle’s wheels.
5-66
ProCarManuals.com
Page 261 of 342
{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop cracks
after many miles of driving. A tire and/or
wheel could fail suddenly, causing a crash.
Use only radial-ply tires with the wheels on
your vehicle.
If you must replace your vehicle’s tires with those that
do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias-belted tires) as your
vehicle’s original tires.
Vehicles that have a tire pressure monitoring system
could give an inaccurate low-pressure warning if
non-TPC Spec rated tires are installed on your vehicle.
Non-TPC Spec rated tires may give a low-pressure
warning that is higher or lower than the proper warning
level you would get with TPC Spec rated tires.
SeeTire Pressure Monitor System on page 5-58.
Your vehicle’s original equipment tires are listed on the
Tire and Loading Information label. SeeLoading
Your Vehicle on page 4-23, for more information about
the Tire and Loading Information label and its location
on your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle
has electronic systems such as, anti-lock brakes,
traction control, and stability control, the performance of
these systems can be affected.
{CAUTION:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will crash
and suffer serious injury. Only use Saturn
speci c wheel and tire systems developed for
your vehicle, and have them properly installed
by a Saturn certi ed technician.

Tire Sealant and Compressor Kit
Your vehicle has a tire sealant and compressor kit that
is capable of temporarily sealing a puncture up to a
1 4inch (6 mm) in the tread of the tire. There is no
jack or spare tire. The kit in ates the tire with liquid
sealant and air. The tire sealant and compressor kit can
also be used to in ate an underin ated tire. After the
tire is in ated to the recommended in ation pressure,
seeInflation - Tire Pressure on page 5-56for more
information, the vehicle must be driven for ve miles to
distribute the sealant in the tire and seal the puncture.
After driving ve miles, the tire pressure must be
rechecked and adjusted as needed. See Using the
Tire Sealant and Compressor later in this section.
Be sure to read and follow all of the tire sealant and
compressor kit instructions. The kit includes the
following:
A. Air Compressor
B. Tire Sealant Canister
C. Air Compressor
Accessory Plug
D. On/Off SwitchE. Air Pressure Gage
F. Air Compressor
In ator Hose
G. Sealant Filling Hose
After temporarily sealing a tire using the tire sealant and
compressor kit, it is recommended to take your vehicle
to an authorized dealer/retailer as soon as possible.
If the sealant is not removed from the tire within
100 miles (161 kilometers) of driving, the dealer/retailer
may recommend that the tire be replaced.

Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal a punctures up to
1 4inch (6 mm) in the tread area of the tire. The sealant
cannot seal sidewall damage, large punctures, or a
tire that has unseated from the wheel. SeeRoadside
Assistance Program on page 7-7if you need assistance.
The sealant can only be used to seal one tire.
After usage, the sealant canister and sealant lling
hose assembly must be replaced at a dealer/retailer.
See Removal and Installation of Sealant Canister later
in this section.
Check the tire sealant expiration date on the sealant
canister, if it has expired, see your dealer/retailer for
a replacement.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal a Punctured Tire
Follow these directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem or tire pressure monitoring
sensor cap from the at tire by turning it
counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.
