Magnetic Ride Control
Magnetic Ride Control automatically adjusts the
ride of your vehicle. Automatic ride control is
achieved through a computer used to control and
monitor the suspension system. The controller
receives input from various sensors to determine
the proper system response. If the controller
detects a problem within the system, the DIC will
display a SERVICE RIDE CONTROL message.
SeeDIC Warnings and Messages on page 206for
more information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a computer controlled
system that helps the driver maintain directional
control of the vehicle in difficult driving conditions.
This is accomplished by selectively applying
any one of the vehicle’s brakes.
When you rst start your vehicle and begin to
drive away (6 mph (10 km/h)), especially during
cold weather, the message STABILITRAK
WARMING may be displayed in the Driver
Information Center (DIC), the instrument panel
cluster light will be on, and a chime will sound.
This is normal. You can acknowledge this
message by pressing the RESET button. The
StabiliTrak
®System performance is affected until
the message, STABILITRAK READY, is
displayed in the DIC. This can take up to
15 minutes.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph
(30 km/h) for 10 seconds if the steering is
not centered. The system is off until the
STABILITRAK ACTIVE message is displayed.

Some road hazards can damage a tire beyond
repair. This damage could occur even before you
have driven on the tire in a deated condition.
When a tire has been damaged, or if you
have driven any distance on a run-at tire, check
with an authorized run-at tire service center
to determine whether the tire can be repaired or
should be replaced. To maintain your vehicle’s
run-at feature, all replacement tires must
be self-supporting tires. As soon as possible,
contact the nearest authorized GM or run-at
servicing facility for inspection and repair or
replacement. To locate the nearest GM or run-at
servicing facility, call Roadside Assistance. For
phone numbers and Roadside Service details see
Roadside Service on page 487.
{CAUTION:
Run-at tires are constructed differently
than other tires and could explode during
improper service. You or others could be
injured or killed if you attempt to repair,
replace, dismount, or mount a run-at tire.
Let only an authorized run-at service
center repair, replace, dismount, and
mount run-at tires.
The valve stems on your run-at tires have
sensors that are part of the Tire Pressure Monitor
System (TPMS). SeeTire Pressure Monitor
System on page 423. These sensors contain
batteries which are designed to last for 10 years
under normal driving conditions. See your dealer if
you ever need to have a wheel replaced, or if
the sensors ever need replacement.
Notice:Using liquid sealants can damage the
tire valves and tire pressure monitor sensors in
your vehicle’s run-at tires. This damage would
not be covered by warranty. Do not use liquid
sealants in your vehicle’s run-at tires.
421

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 underinated. 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.
Recheck 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 (TPM)
Your vehicle has a Tire Pressure Monitor (TPM)
that sends tire pressure information to the
Driver Information Center (DIC). Using the DIC
control buttons, the driver is able to check
tire pressure levels in all four road tires. SeeTire
Pressure Monitor System on page 423and
DIC Controls and Displays on page 204for
additional information.
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. TPMS
sensors are mounted onto each tire and wheel
assembly on your vehicle. The TPMS sensors
monitor the air pressure in your vehicle’s tires and
transmit the tire pressure readings to a receiver
located in the vehicle.
423

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 moretires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
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 354,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 422
for additional information.
Your vehicle’s TPMS can warn you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 426,When It Is Time for
New Tires on page 428, andTires on page 413.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
425

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 your 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’s side front tire, passenger’s side
front tire, passenger’s side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool.
See your dealer for service.

Tire Inspection and Rotation
The tires on your vehicle should be inspected
regularly for wear. Also check for damaged tires or
wheels. SeeWhen It Is Time for New Tires on
page 428andWheel Replacement on page 432for
additional information.
If your vehicle has P235/50R18 size tires they
should be rotated any time you notice
unusual wear.
426

When rotating P235/50R18 size 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, seeInation - Tire
Pressure on page 422andLoading Your Vehicle on
page 354. Vehicles that have the Tire Pressure
Monitor (TPM) system will need to have the sensors
reset after a tire rotation is performed. A special tool
is needed to reset the sensor identication codes.
See your dealer for service. Make certain that all
wheel nuts are properly tightened. SeeWheel
Replacement on page 432and “Wheel Nut Torque”
underCapacities and Specications on page 458.
{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.
XLR-V Tires
Tire rotation is not recommended if your vehicle
has P235/45R19 size tires on the front axle
and P255/40R19 size tires on the rear axle.
Different tire sizes front to rear should not
be rotated.
