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.

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, excluding the spare tire
and wheel assembly, if the vehicle
has one. 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 on the instrument panel
cluster. If the warning light comes on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the tire loading
information label. See
Vehicle Load
Limits on page 9‑11.
Using the Driver Information Center
(DIC), the driver can also check tire
pressure levels using the DIC. For
additional information and details
about the DIC operation and
displays see Driver Information
Center (DIC)
on page 5‑27and
Tire Messageson page 5‑43.
A DIC warning message to check
the pressure in a specific tire is also
shown on the DIC display screen.
The low tire pressure warning light
and the DIC warning message come
at each ignition cycle until the tires
are inflated to the correct inflation
pressure.

10-78 Vehicle Care
The low tire pressure warning light
may come on in cool weather when
the vehicle is first 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 inflated to the
proper pressure.
The Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for the
tires when they are cold. See
Vehicle Load Limits
on page 9‑11,
for an example of the Tire and
Loading Information label and its
location on your vehicle. Also see
Tire Pressure on page 10‑74.
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑80,Tire Rotationon
page 10‑81and Tires on
page 10‑66. Notice:
Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit
on page 10‑92for
information regarding the inflator kit
materials and instructions.
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 flashes 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,
if the vehicle has one. 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.

3. Press the Remote Keyless Entry(RKE) transmitter's lock and
unlock buttons at the same time
for approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and Tire Learning Active
message displays on the DIC
screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve stem. Activate the TPMS
sensor by increasing or
decreasing the tire's air pressure
for 10 seconds, or until a horn
chirp sounds. The horn chirp,
which can take up to 30 seconds
to sound, confirms that the
TPMS sensor identification code
has been matched to this tire
position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5. 7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in
Step 5.
9. After hearing the confirming horn chirp, for the driver side rear tire,
the horn sounds two more times
to signal the tire learning mode
is no longer active. Turn the
ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the tire
and loading information label.
11. Put the valve caps back on the valve stems.
Tire Inspection
We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage at least once
a month. Always remove the tires 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.
