2007 SATURN AURA Owners Manual

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor System
(TPMS). This system uses radio and sensor
technology to check tire pressure levels. Sensors
are mounted onto each tire and wheel assembly.
The TPMS sensors monitor the air pressure
in your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)

As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-ination has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the
telltale will ash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
When a low tire pressure condition is detected, the
TPMS illuminates the low tire pressure warning light
on the instrument panel cluster, and at the same
time the CHECK TIRE PRESS message appears
on the Driver Information Center (DIC) display.

ProCarManuals.com

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 inated to the correct
ination 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 inated 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 ination
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 seeInation - 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 Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identication 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 ination
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
conrm the sensor identication 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 ination 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.

ProCarManuals.com

Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications.
{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.
When It Is Time for New Tires
Various factors, such as maintenance,
temperatures, driving speeds, vehicle loading,
and road conditions inuence 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.
311
ProCarManuals.com

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 ination 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 specic 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 Specication (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 specications 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.
