Audio System
When using the in-vehicle Bluetooth system, sound
comes through the vehicle’s front audio system speakers
and overrides the audio system. Use the audio system
volume knob, during a call, to change the volume level.
The adjusted volume level remains in memory for later
calls. To prevent missed calls, a minimum volume level
is used if the volume is turned down too low.
Bluetooth Controls
Use the buttons located on the steering wheel to
operate the in-vehicle Bluetooth system. SeeAudio
Steering Wheel Controls on page 3-110for more
information.
b>(Push To Talk):Press to answer incoming calls,
to con rm system information, and to start speech
recognition.
cx(Phone On Hook):Press to end a call, reject a
call, or to cancel an operation.
Pairing
A Bluetooth enabled cell phone must be paired to the
in-vehicle Bluetooth system rst and then connected to
the vehicle before it can be used. See the cell phone
manufacturers user guide for Bluetooth functions before
pairing the cell phone. If a Bluetooth phone is not
connected, calls will be made using OnStar
®Hands-Free
Calling, if available. Refer to the OnStar owner’s guide
for more information.
Pairing Information:
Up to ve cell phones can be paired to the in-vehicle
Bluetooth system.
The pairing process is disabled when the vehicle is
moving.
The in-vehicle Bluetooth system automatically links
with the rst available paired cell phone in the order
the phone was paired.
Only one paired cell phone can be connected to the
in-vehicle Bluetooth system at a time.
Pairing should only need to be completed once,
unless changes to the pairing information have
been made or the phone is deleted.
To link to a different paired phone, see Linking to a
Different Phone later in this section.

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. 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 your vehicle has the uplevel Driver Information
Center (DIC), a warning message to check the pressure
in a speci c tire displays at the same time the low tire
pressure warning light comes on. The low tire pressure
warning light and the DIC warning message come on at
each ignition cycle until the tires are in ated to the correct
in ation pressure. Vehicles that have the uplevel DICbuttons can also check tire pressure levels by pressing
the gages button. For additional information and details
about the DIC operation and displays seeDIC Operation
and Displays on page 3-48andDIC Warnings and
Messages on page 3-56
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 in ated 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 in ation pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 4-20, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also seeInflation - Tire Pressure on page 5-61.
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-67andTires on page 5-54.
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.
