Magnetic Ride Control
Your vehicle may have a feature called Magnetic
Ride Control that 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
SUSPENSION SYS message. SeeDIC Warnings
and Messages on page 246for more information. If
this message appears, have your vehicle serviced
at your dealership.
Electronically Controlled Air Ride
Suspension
If you have a Cadillac Professional Vehicle, you
may have a feature called Electronically Controlled
Air Suspension. Air ride control is achieved through
a computer used to control and monitor the system.
310

The controller receives input from two height
sensors to determine the proper system response.
If the controller detects a problem with the system,
the Driver Information Center (DIC) will display a
SERVICE SUSPENSION SYS message. If this
message appears, have your vehicle serviced at
your dealership.
StabiliTrak®System
Your vehicle may have this feature. The
StabiliTrak®system is an advanced 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 and
reducing engine power.
The StabiliTrak
®system comes on automatically
whenever you start your vehicle. The system
cannot be turned off.The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control
system and StabiliTrak
®warning light on the

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. Sensors are mounted on each tire and
wheel assembly, except the spare tire. The TPMS
sensors monitor the air pressure in your vehicle’s
tires and transmit tire pressure readings to a
receiver located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. A Driver Information Center (DIC) message
to check the pressure in a specic tire will also
appear on the DIC display. The low tire pressure
warning symbol on the instrument panel cluster
and the CHECK TIRE PRESSURE message
on the DIC display will appear 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 Controls and Displays on page 240and
DIC Warnings and Messages on page 246.
You may notice, during cooler weather conditions,
that the low tire pressure warning symbol and
the CHECK TIRE PRESSURE message willdisplay when the vehicle is rst started and then
turn off as you start to drive the vehicle. This could
be an early indicator that the tire pressures are
getting low and need to be checked and inated to
the proper pressure.
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.
414

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.
A Tire and Loading Information Label, attached to
your vehicle, shows the size of your vehicle’s
original tires and the correct ination pressure for
your vehicle’s tires when they are cold. See
Loading Your Vehicle on page 333, for the location
of the Tire and Loading Information label. Also
seeInation - Tire Pressure on page 411.
Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 418andTires on page 402.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
415

Resetting the TPMS Sensor
Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors, rotate the vehicle’s tires, or
install a full-size spare that has a TPMS sensor,
the sensor’s identication codes will need to
be matched to the new tire/wheel position. Each
tire/wheel position is matched to the TPMS sensor
using a TPMS diagnostic tool. See your GM
dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
air pressure, do not exceed the maximum tire
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all
four tire and wheel positions 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 RUN with the
engine off.
3. Press the Driver Information Center (DIC)
vehicle information button until the PRESS
VTO RELEARN TIRE POSITIONS displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate that the TPMS is ready,
and then the message TIRE LEARNING
ACTIVE will display. The sensor matching
process can begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the 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,
conrms that the sensor identication code has
been matched to this tire position. To decrease
the tire’s air-pressure use the pointed end of
the valve cap, a pencil-style air pressure gage
or a key.
416

7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming horn chirp for the
driver’s side rear tire, the tire learning process
ends. 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.
The compact spare tire does not have a TPMS
sensor. If you replace one of the road tires with the
compact spare, the SERVICE TIRE MONITOR
SYSTEM message will be displayed on the DIC
screen. This message should go off once you
re-install the road tire containing the TPMS sensor.Federal Communications

Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the sensors
reset after a tire rotation is performed. See
Tire Pressure Monitor System on page 414.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 460.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 428.
When It Is Time for 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.
You need a new tire 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.
