Voice Recognition
The Bluetooth system uses voice recognition
to interpret voice commands to dial phone
numbers and name tags.
For additional information, say“Help”while
you are in a voice recognition menu.
Noise : Keep interior noise levels to a
minimum. The system may not recognize
voice commands if there is too much
background noise.
When to Speak : A short tone sounds after
the system responds indicating when it is
waiting for a voice command. Wait until the
tone and then speak.
How to Speak : Speak clearly in a calm and
natural voice.
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.

would otherwise accelerate due to steepness
of grade. When you shift to 1 (First) it
provides the lowest gear appropriate to
current road speed and continues to
downshift as the vehicle slows, eventually
downshifting to 1 (First) gear. The
transmission can be held in 1 (First) gear
using Range Selection Mode or the shift
lever. See“Range Selection Mode” under
Manual Mode 0144.
Caution
Spinning the tires or holding the vehicle
in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be
covered by the vehicle warranty. If the
vehicle is stuck, do not spin the tires.
When stopping on a hill, use the brakes
to hold the vehicle in place.
Normal Mode Grade Braking
This mode is enabled when the vehicle is
started, but is not enabled in Range
Selection Mode. It assists in maintaining
desired vehicle speeds when driving on
downhill grades by using the engine and transmission to slow the vehicle. The first
time the system activates for each ignition
key cycle.
To disable or enable Normal Mode Grade
Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.
For other forms of grade braking, see

to select the desired range of gears for
current driving conditions.
When M (Manual Mode) is selected, the
transmission will downshift and a number
displays in the Driver Information
Center (DIC) next to the M indicating the
current gear.
This number is the highest gear that can be
used. However, the vehicle can automatically
shift to lower gears as it adjusts to driving
conditions. This means that all gears below
that number are available. When 5 (Fifth) is
selected, 1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle, but
6 (Sixth) cannot be used until the +/−
button on the shift lever is used to change
to the gear.
Grade Braking is not available when Range
Selection Mode is active. See Tow/Haul
Mode 0145.
While using Range Selection Mode, cruise
control and the Tow/Haul Mode can

the air pressure in the tires and transmit 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 cluster. If the warning light
comes on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the Tire and Loading
Information label. SeeVehicle Load Limits
0 131.
A message to check the pressure in a
specific tire displays in the Driver
Information Center (DIC). The low tire
pressure warning light and the DIC warning
message come on at each ignition cycle
until the tires are inflated to the correct
inflation pressure. If the vehicle has DIC
buttons, tire pressure levels can be viewed.
For additional information and details about
the DIC operation and displays, see Driver
Information Center (DIC) 081. The low tire pressure warning light may
come on in cool weather when the vehicle is
first started, and then turn off as the vehicle
is driven. This could be an early indicator
that the air pressure is getting low and
needs to be inflated to the proper pressure.
A Tire and Loading Information label shows
the size of the original equipment tires and
the correct inflation pressure for the tires
when they are cold. See
Vehicle Load Limits
0 131, for an example of the Tire and
Loading Information label and its location.
Also see Tire Pressure 0216.
The TPMS can warn about a low tire
pressure condition but it does not replace
normal tire maintenance. See Tire Inspection
0 220, Tire Rotation 0220 and
Tires 0211.
Caution
Tire sealant materials are not all the
same. A non-approved tire sealant could
damage the 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.
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 pressure warning
light flashes for about one minute and then
stays on for the remainder of the ignition
cycle. A DIC warning message also displays.
The malfunction light and DIC warning
message come on at each ignition cycle
until the problem is corrected. Some of the
conditions that can cause these 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 malfunction
light and the DIC message should go off
after the road tire is replaced and the
sensor matching process is performed
successfully. See "TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching process was
not done or not completed successfully
after rotating the tires. The malfunction
light and the DIC message should go off
after successfully completing the sensor
matching process. See "TPMS Sensor
Matching Process" later in this section.

Vehicle Care 219
.One or more TPMS sensors are missing or
damaged. The malfunction light and the
DIC message should go off when the
TPMS sensors are installed and the sensor
matching process is performed
successfully. See your dealer for service.
.Replacement tires or wheels do not match
the original equipment tires or wheels.
Tires and wheels other than those
recommended could prevent the TPMS
from functioning properly. SeeBuying
New Tires 0222.
.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 properly, it
cannot detect or signal a low tire pressure
condition. See your dealer for service if the
TPMS malfunction light and DIC message
come on and stay on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification code
needs to be matched to a new tire/wheel
position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors.
Also, the TPMS sensor matching process should be performed after replacing a spare
tire with a road tire containing the 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.
A TPMS relearn tool can also be purchased.
See Tire Pressure Monitor Sensor Activation
Tool at www.gmtoolsandequipment.com or
call 1-800-GM TOOLS (1-800-468-6657).
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 on without starting the vehicle. See Ignition Positions 0135.
3. Press the Remote Keyless Entry (RKE) transmitter's
QandKbuttons 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.
If the vehicle does not have RKE, press
the Driver Information Center (DIC)
vehicle information button until the
PRESS
VTO RELEARN TIRE POSITIONS
message displays. 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
