tire pressure SATURN VUE HYBRID 2008 Owner's Manual

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 identication code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle’s tires, the identication codes
will 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
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 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 will 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 RKE transmitter’s lock
and unlock buttons at the same time, for about
three seconds. The horn sounds twice to indicate
the receiver is ready for the sensor matching process
to begin. The TIRE LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire. The driver side
turn signal lamp comes on.
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 ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds to sound,
conrms that the sensor identication code
has been matched to the tire/wheel position.
6. Proceed to the passenger side front tire.
The passenger side front turn signal lamp
comes on. Repeat the procedure in Step 5.

7. Proceed to the passenger side rear tire.
The passenger side rear turn signal lamp
comes on. Repeat the procedure in Step 5.
8. Proceed to the driver side rear tire. The driver
side rear turn signal lamp comes on. Repeat the
procedure in Step 5. The horn sounds two times to
indicate the sensor identication code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
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.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires for signs of wear or damage.
SeeWhen It Is Time for New Tires on page 5-59
for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
on page 6-4.The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform most
like it did when the tires were new.
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 5-59andWheel
Replacement on page 5-64for more information.
When rotating the vehicle’s 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. SeeInflation - Tire
Pressure on page 5-52andLoading Your Vehicle
on page 4-22.
5-58
ProCarManuals.com

Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-55.
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.
5-59
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, 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 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 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 5-48for 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 5-58for
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.
{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 5-54.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information label. SeeLoading
Your Vehicle on page 4-22, for more information about
the Tire and Loading Information label and its location

Tire Sealant and Compressor Kit
Your vehicle is equipped with a tire sealant and
compressor kit that is capable of temporarily sealing a
puncture up to a
14inch (6 mm) in the tread area of the
tire. There is no jack of spare tire. The kit inates with
liquid sealant and air. The tire sealant and compressor
kit can also be used to inate an underinated tire. After
the tire is inated to the recommended pressure, see
Inflation - Tire Pressure on page 5-52, the vehicle must
be driven for ve miles to distribute the sealant in the
tire and seal the puncture. See “Using the Tire Sealant
and Compressor Kit to Temporarily Seal and Inate a
Punctured Tire” later in this section.
After temporarily repairing a tire using the tire sealant
and compressor kit, take your vehicle to an authorized
dealer/retailer as soon as possible. If the sealant is
within 100 miles (161 kilometers) of driving, then it is
easier to clean from the tire and you are less likely
to require a replacement tire.A. Air Compressor

The sealant cannot seal sidewall damage, large
punctures, or a tire that has become unseated from
the wheel. SeeRoadside Assistance Program on
page 7-6.
Do not remove any objects that have penetrated
the tire.
3. Place the tire sealant and compressor kit on the
ground and unwrap the sealant/air hose (G) from
the side of the compressor.
4. Remove the valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the sealant/air hose (G) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit on/off
switch (D) is in the O (off) position.
6. Remove the air compressor accessory plug (C)
from the unit.
7. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-17for more information.
Do not slam door or close window on the
compressor accessory plug cord.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-29.
8. Start the vehicle. SeeStarting the Engine
(Automatic Engine Start/Stop) on page 2-18
for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
Overination could cause the tire to rupture,
and you or others could be injured. Be sure to
read the inator instructions, and inate the
tire to its recommended pressure. Do not
exceed 36 psi (248 kPa).

9. Push the On/Off switch (D) to the I (on) position.
The tire sealant and compressor kit will inject
sealant and air into the tire.
The pressure gage (E) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completely
dispersed into the tire, the pressure will quickly drop
and start to rise again as the tire inates with air only.
10. Inate the tire to the recommended ination
pressure using the air pressure gage (E) on the top
of the unit. The recommended ination pressure
can be found on the Tire and Loading Information
label. SeeInflation - Tire Pressure on page 5-52.
The pressure gage reading is slightly high while the
compressor is on. Turn the compressor off to get
an accurate reading. The compressor may be turned
on and off until the correct pressure is reached.
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 inating hose from the tire
valve. SeeRoadside Assistance Program on
page 7-6for more information.11. Turn the compressor off by pushing the On/Off
switch (D) to the O (off) position.
Steps 12 through 20 must be done immediately
after Step 11.
The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant
is distributed in the tire.
Be careful while handling the tire sealant and
compressor kit as they could be hot after usage.
12. Unplug the air compressor accessory plug (C) from
the accessory power outlet in the vehicle.
13. Disconnect the sealant/air hose (G) from the tire
valve stem by turning it counterclockwise and
replace the tire valve stem cap.
14. Wrap the sealant/air hose (G) around the air
compressor channel to stow it in its original location.
15. Stow the air compressor accessory plug (C) back
in the air compressor. To do this, wrap the air
compressor accessory plug, snap in the plug, and
then push in the bottom and then the top of the
wrapped air compressor accessory plug.

16. If the at tire was
able to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister (B).
17. Place it in a highly visible location such as the
inside of the upper left corner of the windshield
or to the face of the radio/clock.
The maximum speed label reminds you to drive
cautiously and not to exceed 55 mph (90 km/h) until
you have the damaged tire inspected and repaired.
{CAUTION:
Storing the tire sealant and compressor
kit or other equipment in the passenger
compartment of the vehicle could cause injury.
In a sudden stop or collision, loose equipment
could strike someone. Store the tire sealant
and compressor kit in its original location.
18. Return the equipment to its original storage location
in your vehicle.
19. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire.

20. Stop at a safe location and check the tire pressure,
refer to Steps 1 through 8 under “Using the Tire
Sealant and Compressor Kit without Sealant
to Inate an Underinated Tire (Not Punctured)”
later in this section.
If the tire pressure has fallen more then 10 psi
(68 kPa), below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant and compressor kit
cannot seal the tire. SeeRoadside Assistance
Program on page 7-6for more information.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to
the recommended ination pressure.
21. Wipe off any sealant from the wheel, tire and
vehicle.
22. Dispose of the sealant canister (B) and sealant/air
hose (G) assembly at a local dealer/retailer or in
accordance with your local state codes and
practices.
23. After temporarily sealing a tire with the tire
sealant and compressor kit, take your vehicle
to an authorized dealer/retailer to have the tire
inspected and repaired or replaced.Using the Air Compressor without
Sealant to Inate an Underinated Tire
(Not Punctured)
To use the air compressor to inate a tire with air only
and not sealant:
1. Unlock the air only hose (F) from the sealant
canister (B) by pulling up on the lever.
2. Pull the air only hose (F) from the sealant
canister (B).
3. Remove the tire valve stem cap by turning it
counterclockwise.
