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. The spare tire does not have a TPMS
sensor. The DIC message should go off once you
re-install the road tire containing the TPMS sensor.
The TPMS sensor matching process was not
done or not completed successfully after rotating
the vehicle’s tires. The DIC message should go off
after successfully completing the sensor matching
process. 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. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-76.
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.

12. The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant is
distributed in the tire.
Steps 11 through 18 must be done right after
Step 10.
13. Unplug the air compressor accessory plug (F) from
the accessory power outlet in the vehicle.
14. Disconnect the sealant/air hose from the tire valve
stem or tire pressure monitoring sensor cap, by
turning it counterclockwise, and replace the
tire valve stem cap.
Be careful when handling the tire inator
components as they may be hot after usage.
15. Wrap the sealant/air hose around the air
compressor channel to stow it in its original location.
16. Wrap the air compressor accessory plug (E)
back into place.17. 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.

17. 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 its original location.
18. Return the equipment to its original storage location
in your vehicle.
19. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire.20. Stop at a safe location and check the tire pressure,
refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant
to Inate an Underinated Tire (Not Punctured)”
next in this section.
If the tire pressure has fallen more then 10 psi
(68 kPa), below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant and compressor kit
cannot seal the tire. SeeRoadside Service on
page 7-7for more information.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire back up to the
recommended ination pressure.
21. Wipe off any sealant from the wheel, tire, and
vehicle.
22. Dispose of the sealant canister (B) and sealant/air
hose (G) assembly at a local dealer/retailer or in
accordance with your local state codes and
practices.
After using the sealant canister, replace it with a
new canister from your dealer/retailer.
23. After temporarily sealing a tire with the tire sealant
and compressor kit, take your vehicle to your
dealer/retailer to have the tire repaired or replaced.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. 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.
Underhood Fuse Block
The underhood fuse
block is located on the
passenger side of
the engine compartment.
Lift the fuse block cover to access the fuses.
Notice:Spilling liquid on any electrical components
on your vehicle may damage it. Always keep the
covers on any electrical component.

Note to Canadian Customers: All listed prices are

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.

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 2-55in 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.
