Run-Flat Tires
This vehicle, when new, had run-at tires. There is no
spare tire, no tire changing equipment, and no place
to store a tire in the vehicle. 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.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of your vehicle. You or others could be
injured. Do not drive over 55 mph (90 km/h)
when the low tire warning light is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
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 thespeed, 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 tires on coupe, convertible and
Z06 models 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.
The tires on ZR1 models can operate effectively with no
air pressure for up to 50 miles (80 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.
5-69

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 7-7.
{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 5-73.
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.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in the
vehicle’s run-at tires. This damage would not be
covered by warranty. Do not use liquid sealants
in the vehicle’s run-at tires.
Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards

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.)
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.
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.
SeeTire Pressure Monitor Operation on page 5-74for
additional information.

Federal Communications
Commission (FCC) and Industry
and Science Canada
The Tire Pressure Monitor System (TPMS) operates
on a radio frequency and complies with Part 15 of the
FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
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
This vehicle may have a Tire Pressure Monitor
System (TPMS). The 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 seeDIC Operation and
Displays on page 3-49andDIC Warnings and Messages
on page 3-54.
5-74

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.
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 4-22, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also seeInflation - Tire Pressure on page 5-70for
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 5-76,When It Is Time for New Tires on page 5-77,
andTires on page 5-62.
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.
5-75

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 5-78.
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 5-77andWheel Replacement
on page 5-82.
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.
5-76

The 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 5-69andTire Pressure Monitor System on
page 5-73.
{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 the vehicle could be damaged. Always
be sure the proper tools and procedures, as
described in the service manual, are used.
To order a service manual, seeService Publications
Ordering Information on page 7-15.
Appearance Care
Interior Cleaning
The vehicle’s interior will continue to look its best if it
is cleaned often. Although not always visible, dust and
dirt can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from
the upholstery. It is important to keep the upholstery from
becoming and remaining heavily soiled. Soils should be
removed as quickly as possible. The vehicle’s interior
may experience extremes of heat that could cause
stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to home furnishings may also transfer
color to the vehicle’s interior.
