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 5-72for
additional information.

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, excluding the spare tire and wheel
assembly. 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.

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:
One of the road tires has been replaced with the
spare tire and wheel. The spare, if your vehicle has
one, does not have a TPMS sensor. The TPMS
malfunction light and DIC message should go off
once you re-install the road tire containing the
TPMS sensor.
The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tire 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 the vehicle’s tires, the identication codes 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 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 pressure, do not
exceed the maximum ination pressure indicated on the
tire’s sidewall. To decrease the tire’s air-pressure use the
pointed end of the valve cap, a pencil-style air pressure
gage, or a key.

15. Stow the air compressor accessory plug back in the
air compressor. To do this, wrap the air compressor
accessory plug, snap in the plug, and then push in
the bottom and then the top of the wrapped air
compressor accessory plug.
16. If the at tire was able
to inate to the
recommended ination
pressure, remove the
maximum speed label
from the sealant
canister.
Place it in a highly visible location such as the
inside of the upper left corner of the windshield or
to the face of the radio/clock.
The maximum speed label reminds you to drive
cautiously and not to exceed 55 mph (90 km/h) until
you have the damaged tire inspected and repaired.
{CAUTION:
Storing the tire sealant and compressor kit or
other equipment in the passenger
compartment of the vehicle could cause injury.
In a sudden stop or collision, loose equipment
could strike someone. Store the tire sealant
and compressor kit in the proper place.
17. Return the equipment to the proper storage location
in the trunk of your vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire. Stop at a
safe location and check the tire pressure. Refer to
Steps 1 through 8 under “Using the Air Compressor
without Sealant” next in this section. If the tire
pressure has fallen more than 10 psi (68 kPa) below
the recommended ination pressure, stop driving
the vehicle. The tire is too damaged for the sealant to
work. SeeRoadside Assistance Program on
page 7-6.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to the
recommended ination pressure.

Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without – like the radio or cigarette
lighter – and use its fuse, if it is the correct amperage.
Replace it as soon as you can.

Vehicle Data Recording
and Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example,
your vehicle uses computer modules to monitor
and control engine and transmission performance,
to monitor the conditions for airbag deployment
and deploy airbags in a crash and, if so equipped,
to provide antilock braking to help the driver control
the vehicle. These modules may store data to help
your dealer/retailer technician service your vehicle.
Some modules may also store data about how
you operate the vehicle, such as rate of fuel
consumption or average speed. These modules
may also retain the owner’s personal preferences,
such as radio pre-sets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle has an Event Data Recorder (EDR).
The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an airbag
deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems
performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The EDR
in this vehicle is designed to record such data as:
How various systems in your vehicle were operating
Whether or not the driver and passenger safety
belts were buckled/fastened
How far, if at all, the driver was pressing the
accelerator and/or brake pedal
How fast the vehicle was traveling
This data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
7-16

Important:EDR data is recorded by your vehicle
only if a non-trivial crash situation occurs; no data is
recorded by the EDR under normal driving conditions
and no personal data (e.g., name, gender, age,
and crash location) is recorded. However, other parties,
such as law enforcement, could combine the EDR data
with the type of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR
is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have the
special equipment, can read the information if they
have access to the vehicle or the EDR.
GM will not access this data or share it with others
except: with the consent of the vehicle owner or,
if the vehicle is leased, with the consent of the lessee;
in response to an official request of police or similar
government office; as part of GM’s defense of litigation
through the discovery process; or, as required by
law. Data that GM collects or receives may also be
used for GM research needs or may be made available
to others for research purposes, where a need is
shown and the data is not tied to a specic vehicle
or vehicle owner.OnStar®
If your vehicle has OnStar and you subscribe to the
OnStar services, please refer to the OnStar Terms
and Conditions for information on data collection and
use. See alsoOnStar
®System on page 2-40in
this manual for more information.
Navigation System
If your vehicle has a navigation system, use of the
system may result in the storage of destinations,
addresses, telephone numbers, and other trip
information. Refer to the navigation system operating
manual for information on stored data and for
deletion instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some vehicles for functions
such as tire pressure monitoring and ignition system
security, as well as in connection with conveniences
such as key fobs for remote door locking/unlocking and
starting, and in-vehicle transmitters for garage door
openers. RFID technology in GM vehicles does not
use or record personal information or link with any other
GM system containing personal information.
