The low tire pressure warning light on the
instrument panel cluster, and the CHECK TIRE
PRESS message displays at each ignition
cycle until the tires are in ated to the correct
in ation pressure. For additional information and
details about the DIC operation and displays
seeDIC Operation and Displays on page 180and
DIC Warnings and Messages on page 182.
The 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 tire pressures are getting low and
need to be in ated to the proper pressure.
A Tire and Loading Information label, attached to
your vehicle, 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 242,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeIn ation - Tire Pressure on page 304.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 310andTires on
page 298.
Notice:Your vehicle has a Tire Pressure
Monitor System (TPMS). Use only the
GM-provided tire sealant. Other liquid tire
sealants may damage the tire pressure
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
See your Saturn retailer for service if all TPMS
sensors are installed and the TPMS error message
comes on and stays on.

TPMS Sensor Identi cation Codes
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 position. The sensors are matched,
to the tire/wheel positions, 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 Saturn
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 with the
engine off.
3. Press and hold both the Lock and Unlock
buttons on the Remote Keyless Entry
(RKE) transmitter, at the same time, for
approximately ve seconds or until you hear
the horn sound twice.
4. The horn sounding twice indicates the
receiver is ready to learn the TPMS sensors.
The driver side front turn signal comes on
indicating that corner’s sensor is ready to be
learned.
5. Start with the driver side front tire.
6. 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 sounds one
time and all the turn signals ash one time to
con rm the sensor identi cation code has
been matched to the tire/wheel position.

7. The passenger side front turn signal comes
on to indicate that corner’s sensor is ready to
be learned. Proceed to the passenger side
front tire and repeat the procedure in Step 6.
8. The passenger side rear turn signal comes on
to indicate that corner’s sensor is ready to be
learned. Proceed to the passenger side
rear tire and repeat the procedure in Step 6.
9. The driver side rear turn signal comes on to
indicate that corner’s sensor is ready to be
learned. Proceed to the driver side rear
tire, and repeat the procedure in Step 6.
10. 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 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.Federal Communications Commission

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 311andWheel
Replacement on page 316for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. See “Scheduled
Maintenance” for additional information.When rotating your tires, always use the correct
rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear in ation pressures as shown on the
Tire and Loading Information label. SeeLoading
Your Vehicle on page 242, for an example of
the tire and loading information label and
its location on your vehicle.

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. This is
true for the spare tire as well, even if it is not being
used. 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 by the tire manufacturer.
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 299for additional information.

The kit includes:
A. Air Compressor
B. Tire Sealant
Canister
C. Air Compressor
Accessory PlugD. On/Off Switch
E. Air Pressure Gage
F. Air Compressor
In ator Hose
G. Sealant Filling HoseIf the at tire is due to a slow leak caused by a
nail or other similar road hazard, use the tire
in ator kit to temporarily repair the damaged tire.
After temporarily repairing a tire using the tire
in ator kit, take your vehicle to an authorized
dealer/retailer within 100 miles (161 kilometers) of
driving to have the tire inspected and repaired.
If the sealant is not removed from the tire
within 100 miles (161 kilometers) of driving, it is
more likely that the tire can get damaged and have
to be replaced.

{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 123.
6. Start the vehicle. SeeStarting the Engine
(Automatic Engine Start/Stop) on page 110
for more information. The vehicle must
be running while using the air compressor.
{CAUTION:
In ating something too much can make it
explode, and you or others could be
injured. Be sure to read the in ator
instructions, and in ate the tire to its
recommended pressure. Do not exceed
36 psi (248 kPa).
7. Push the in ator kit switch to the I (on)
position.
The in ator kit forces sealant and air into the
tire. Sealant could leak from the puncture
hole until the vehicle is driven and the
hole has sealed.

8. Make sure there is a proper connection
between the tire valve stem and the sealant
lling hose by looking at the air pressure gage.
If there is not a pressure reading while the
compressor is running, the connection between
the in ator kit and the tire is bad.
Check the attachment between the sealant
lling hose and the tire valve stem.
9. In ate the tire up to the recommended
in ation pressure, found on the Tire and
Loading Information label located on
the vehicle’s center pillar (B-pillar) below the
vehicle’s door latch, using the air pressure
gage on the top of the unit.
The pressure gage reading is slightly high
while the compressor is on. Turn the
compressor off to get an accurate pressure
reading.Notice:If the recommended pressure cannot
be reached after 15 minutes, the vehicle
should not be driven farther. Damage to the
tire is severe and the sealant will not be
effective. Remove the air compressor plug
from the accessory power outlet and unscrew
the in ating hose from the tire valve. See
Roadside Assistance Program on page 377.
10. Push the in ator kit switch to the O (off)
position once the correct tire pressure is
obtained.
11. Turn off the engine.
