Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light indicates if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-43.
This light comes on when
the vehicle is started,
and ashes for a
few seconds. The light
should go out when
the system is ready.
If the airbag readiness light stays on after the vehicle is
started or comes on while driving, the airbag system
may not work properly. Have your vehicle serviced
right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away.
The airbag readiness light should ash for a few seconds
when the engine is started. If the light does not come on
then, have it xed immediately. If there is a problem with
the airbag system, an airbag Driver Information Center
(DIC) message may also come on. SeeDIC Warnings
and Messages on page 3-57for more information.

If a tire goes at, you will not need to stop on the
side of the road to change the tire. You can just
keep on driving. The shorter the distance you drive
and the slower the speed, the greater the chance
that the tire will not have to be replaced. If you drive on
a deated run-at tire for 25 miles (40 km) or less
and at speeds of 55 mph (90 km/h) or less, there is a
good chance that the tire can be repaired. The tire can
operate effectively with no air pressure for up to
100 miles (160 km) at speeds up to 55 mph (90 km/h),
but the tire would then have to be replaced. When
a tire is lled with air, it provides a cushion between the
road and the wheel. Because you will not have this
cushion when driving on a deated tire, try to avoid
potholes that could damage your wheel and require
replacement of it.
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 seeRoadside Assistance
Program on page 7-8.
{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 5-68. These
sensors contain batteries which are designed to last
for 10 years under normal driving conditions. See your
dealer/retailer if you ever need to have a wheel
replaced, or if the sensors ever need replacement.
5-65

High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h) or
higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause sudden
tire failure. You could have a crash and you or
others could be killed. Some high-speed rated
tires require ination pressure adjustment for
high speed operation. When speed limits and
road conditions are such that a vehicle can be
driven at high speeds, make sure the tires are
rated for high speed operation, in excellent
condition, and set to the correct cold tire
ination pressure for the vehicle load.
If you will be driving your vehicle at speeds of 175 mph
(282 km/h) or higher, where it is legal, set the cold
ination pressure to the maximum ination pressure
shown on the tire sidewall, or 38 psi (265 kPa), whichever
is lower. See the example following. When you end this
high-speed driving, return the tires to the cold ination
pressure shown on the Tire and Loading Information
label. SeeLoading the Vehicle on page 4-24.Example:
You will nd the maximum load and ination pressure
molded on the tire’s sidewall, in small letters, near
the rim ange. It will read something like this: Maximum
load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the ination pressure
for high-speed driving at 38 psi (265 kPa).
Racing or other competitive driving may affect the
warranty coverage of your vehicle. See your warranty
booklet for more information.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
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.)
5-68

The TPMS operates on a radio frequency and complies
with RSS-210 of Industry and Science Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire
and wheel assembly on your vehicle. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmits the tire pressure readings to a receiver
located in the vehicle.When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light, located in the
instrument panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message appear at each ignition
cycle until the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels can
be viewed by the driver. For additional information and
details about the DIC operation and displays see
DIC Operation and Displays on page 3-52andDIC
Warnings and Messages on page 3-57.
The low 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 air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
5-70

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 the
Vehicle on page 4-24, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 5-66
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 5-72,When It Is Time for New Tires on page 5-73,
andTires on page 5-58.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for
the remainder of the ignition cycle. A DIC warning
message is also displayed. The low tire warning light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause the malfunction light and DIC
message to come on are:
The TPMS sensor matching process was not done
or not completed successfully. The DIC message
should go off after successfully completing the
sensor matching process.
One or more TPMS sensors are missing or
damaged. Under these conditions the TPMS
malfunction light (low tire warning light) comes on,
and at the same time the DIC message is displayed.
The DIC message and TPMS malfunction light
should go off once the TPMS sensors are installed
and the sensor matching process is performed
successfully.
5-71

Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-74.
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 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 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.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires for signs of wear or damage
Also check for damaged wheels. SeeWhen It Is
Time for New Tires on page 5-73andWheel
Replacement on page 5-78.
The tires on your vehicle are different sizes front
to rear. Due to this, the tires should not be rotated.
Each tire and wheel should be used only in the
position it is in.
5-72

If a Tire Goes Flat
Your vehicle has no spare tire, no tire changing
equipment, and no place to store a tire.
It is unusual for a tire to blow out while you are driving,
especially if you maintain your tires properly. If air
goes out of a tire, it is much more likely to leak out
slowly. SeeTires on page 5-58for additional
information.
Your vehicle, when new, had run-at tires. This type of
tire can operate effectively with no air pressure, so you
will not need to stop on the side of the road to change a
at tire. You can just keep on driving. The shorter the
distance you drive and the slower the speed, the greater
the chance that the run-at tire will not have to be
replaced. Run-at tires perform so well without any air
that a Tire Pressure Monitor System (TPMS) is used to
alert you if a tire has lost pressure. SeeRun-Flat Tires on
page 5-64andTire Pressure Monitor System on
page 5-68.{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools and
procedures are not used you or others could
be injured and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
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.
