SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you are
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or other
slippery spot on the road. When the system is on, you
may hear a noise or feel a vibration in the brake pedal.
This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want to
go. The system is designed to help you in bad weather or
other difficult driving situations by making the most of
whatever road conditions will permit. If the STABILITY
SYSTEM ACTIVE message comes on, you will know that
something has caused your vehicle to start to spin, so
you should consider slowing down.Tire Pressure Status – 144:If you see the CHECK
TIRE PRESSURE message, you should stop as soon as
you can and check all your tires for damage. If a tire
is at, seeIf a Tire Goes Flat on page 5-79. Also check
the tire pressure in all four tires as soon as you can.

Tire Pressure System on page 5-68.
Driver Identier DIC Display
This feature allows two different drivers to store and
recall their own preferred display mode. The
personalization settings displayed on the DIC are
determined by the transmitter used to enter the vehicle.
After the unlock button on the remote keyless entry
transmitter (if equipped) is pressed and the ignition is in
ON, the DIC will display the identied driver. The
settings can also be changed by briey pressing one of
the MEMORY buttons located on the driver’s door.
The DIC is used to program information for DRIVER #1
and DRIVER #2. The DIC will identify a person as
UNKNOWN DRIVER if neither DRIVER #1 nor
DRIVER #2 is identied by the system.

(A) Temporary Use Only:The compact spare tire or
temporary use tire has a tread life of approximately
3,000 miles (5 000 km) and should not be driven
at speeds over 65 mph (105 km/h). The compact spare
tire is for emergency use when a regular road tire
has lost air and gone at. SeeCompact Spare Tire on
page 5-90andIf a Tire Goes Flat on page 5-79.
(B) Tire Ply Material:The type of cord and number of
plies in the sidewall and under the tread.
(C) Tire Identication Number (TIN):The Tire
Identication Number (TIN). The TIN shows the
manufacturer and plant code, tire size, and date the tire
was manufactured. The TIN is molded onto both
sides of the tire, although only one side may have the
date of manufacture.
(D) Maximum Cold Ination Load Limit:Maximum
load that can be carried and the maximum pressure
needed to support that load. SeeCompact Spare Tire
on page 5-90andLoading Your Vehicle on page 4-33.

The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-58.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center (DIC) or the systems
monitor TIRE PRESS light comes on, you should stop as
soon as you can and check all your tires for damage. If a
tire is at, seeIf a Tire Goes Flat on page 5-79. Also
check the tire pressure in all four tires as soon as you
can. SeeInation - Tire Pressure on page 5-67.
Any time you adjust a tire’s pressure or have one or more
tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will also
need to reset the system whenever you rotate the tires,
buy new tires and install or remove the compact spare.Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.
To reset (calibrate) the system with a Driver Information
Center (DIC):
1. Turn the ignition switch to ON.
2. Using the MODE and SELECT buttons, change the
DIC to display TIRE PRESSURE.
3. Press and hold the RESET button for about ve
seconds.
4. The display should change to read TIRE
PRESSURE RESET. If TIRE PRESSURE RESET
does not appear on the display after about ve
seconds, see your dealer for service.
5. When you release the button after seeing the TIRE
PRESSURE RESET message, the display will
change to read TIRE PRESSURE NORMAL.

When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Reset the check tire pressure system, if equipped. See
Check Tire Pressure System on page 5-68.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-109.
{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 an accident. 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. See “Changing a Flat
Tire” in the Index.

If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-80for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.

If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.
