TPMS sensor. The malfunction
light and the DIC message should
go off at the next ignition cycle.
The sensors are matched to the
tire/wheel positions, using a TPMS
relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to purchase a
relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUNwith the engine off. 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. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel 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. The horn sounds two
times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.

electrical system, wireless service,
and GPS satellite technologies to
be available and operating for
features to function properly.

your vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area, and the wireless
service provider has coverage,
network capacity, reception, and
technology compatible with
OnStar’s service. Service involving
location information about the
vehicle cannot work unless GPS
signals are available, unobstructed,
and compatible with the OnStar
hardware. OnStar service may not
work if the OnStar equipment is not properly installed or it has
not been properly maintained.
If equipment or software is added,
connected, or modified, OnStar
service may not work. Other
problems beyond OnStar
’s control
may prevent service such as hills,
tall buildings, tunnels, weather,
electrical system design and
architecture of the vehicle, damage
to the vehicle in a crash, or wireless
phone network congestion or
jamming.

have difficulty identifying the
exact location.
.In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.

cause loss of the ability to send
a Turn-by-Turn Navigation route.
The Advisor may give a verbal
route or may ask for a call back
after the vehicle is driven into an
open area.
