7-52 Infotainment System
Phone
Bluetooth
For vehicles equipped with
Bluetooth capability, the system
can interact with many cell phones,
allowing:
.Placement and receipt of calls
in a hands-free mode.
.Sharing of the cell phone’s
address book or contact list
with the vehicle.
To minimize driver distraction,
before driving, and with the vehicle
parked:
.Become familiar with the
features of the cell phone.
Organize the phone book and
contact lists clearly and delete
duplicate or rarely used entries.
If possible, program speed dial
or other shortcuts.
.Review the controls and
operation of the infotainment
system.
.Pair cell phone(s) to the vehicle.
The system may not work with
all cell phones. See “Pairing”in
this section for more information.
.If the cell phone has voice
dialing capability, learn to use
that feature to access the
address book or contact list.
See “Voice Pass-Thru” in this
section for more information.
.See “Storing and Deleting Phone
Numbers” in this section for
more information.
{WARNING
When using a cell phone, it can
be distracting to look too long or
too often at the screen of the
phone or the infotainment
(navigation) system. Taking your
eyes off the road too long or
too often could cause a crash
resulting in injury or death.
Focus your attention on driving. A Bluetooth system can use a
Bluetooth‐capable cell phone with a
Hands‐Free Profile to make and
receive phone calls. The system
can be used while the key is in the
ON/RUN or ACC/ACCESSORY
position. The range of the Bluetooth
system can be up to 9.1 m (30 ft).
Not all phones support all functions,
and not all phones work with the
in-vehicle Bluetooth system. See
www.gm.com/bluetooth for more
information on compatible phones.
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.

Climate Controls 8-7
Automatic Operation
AUTO (Automatic):When
automatic operation is active,
the system controls the inside
temperature, the air delivery,
and the fan speed.
Use the steps below to place the
entire system in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the
display changes to show the
current temperature(s) and
AUTO is lit on the display.
The current air delivery mode
and fan speed are also
displayed for about five seconds.
When AUTO is selected, the air
conditioning operation and air
inlet are automatically controlled.
The air conditioning compressor
may run when the outside
temperature is above freezing.
The air inlet will normally be set
to outside air. If it is hot outside, the air inlet may automatically
switch to the recirculate mode to
help quickly cool down the air
inside the vehicle. The light on
the button comes on in
recirculation.
2. Set the driver and passenger temperature.
To find your comfort setting,
start with a 23°C (74°F)
temperature setting and allow
about 20 minutes for the system
to regulate. Use the driver or
passenger temperature buttons
to adjust the temperature setting
as necessary. If a temperature
setting of 15°C (60°F) is chosen,
the system remains at the
maximum cooling setting. If a
temperature setting of 32°C
(90°F) is chosen, the system
remains at the maximum
heat setting. Choosing either
maximum setting will not cause
the vehicle to heat or cool any
faster. Do not cover the solar sensor
located on the top of the
instrument panel near the
windshield. This sensor regulates
air temperature based on sun load.
For more information on the solar
sensor, see
“Sensors”later in this
section.
To avoid blowing cold air in
cold weather, the system delays
turning the fan on until warm air
is available. The length of delay
depends on the engine coolant
temperature. Pressing the fan
switch overrides this delay and
changes the fan to a selected
speed.

9-36 Driving and Operating
Active Fuel Management®
Vehicles with V8 engines may have
Active Fuel Management™. This
system allows the engine to operate
on either all or half of its cylinders,
depending on the driving conditions.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.
If the vehicle has an Active Fuel
Management™indicator, seeDriver
Information Center (DIC) on
page 5‑32 for more information on
using this display.
Engine Exhaust
{WARNING
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airflow or tail pipes).
.The exhaust smells or
sounds strange or different.
.The exhaust system leaks
due to corrosion or damage.
.The vehicle exhaust system
has been modified, damaged
or improperly repaired.
(Continued)
WARNING (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.

Black plate (42,1)Chevrolet Silverado Owner Manual - 2012
9-42 Driving and Operating
Manual Mode
Range Selection Mode
(Allison®Transmission or
Hydra-Matic®6-Speed
Transmission)
The vehicle may have a Range
Selection Mode. The Range
Selection Mode helps control the
vehicle's transmission and vehicle
speed while driving down hill or
towing a trailer by letting you select
a desired range of gears.
To use this feature, do the following:
1. Move the shift lever to
M (Manual Mode).
2. Press the plus/minus buttons, located on the steering column
shift lever, to select the desired
range of gears for current driving
conditions. When M (Manual Mode) is selected
a number displays 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 plus/minus button located on the
steering column lever is used to
change to the gear.
Grade Braking is not available when
Range Selection Mode is active.
See
Tow/Haul Mode on page 9‑43.
While using Range Selection Mode,
Cruise Control and the Tow/Haul
Mode can be used.
If the vehicle has an exhaust brake,
it can also be used, but will not
automatically downshift the
transmission. See Exhaust Brake in
the Duramax Diesel supplement. Notice:
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 you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Low Traction Mode
If your vehicle has the Allison
Transmission, or the Hydra-Matic
6-Speed Automatic Transmission, it
has a Low Traction Mode that can
assist in vehicle acceleration when
road conditions are slippery, such
as with ice or snow. While the
vehicle is at a stop, select the
second gear range using Range
Selection Mode. This will limit
torque to the wheels after it detects
wheel slip, preventing the tires from
spinning.

9-48 Driving and Operating
When Using the Manual
Transfer Case
.Shifts into or out of Four-Wheel
Drive Low or N (Neutral) should
be made using quick motions to
avoid excessive gear grinding.
Shifting slowly may make it more
difficult to shift.
.You may notice that it is harder
to shift when the vehicle is cold.
After the vehicle warms up the
shifting will return to normal.
.While in Four-Wheel High or
Four-Wheel Drive Low you
may experience reduced fuel
economy.
.Avoid driving in Four-Wheel
Drive on clean, dry pavement.
It may cause your tires to wear
faster, make the transfer case
harder to shift, and run noisier.
.If the transfer case shifter is in
the N (Neutral) position and you
have difficulty reaching the
selected transfer case mode,
with the engine running, shift the
transmission momentarily to
D (Drive) and then back to
N (Neutral). This will realign the
gear teeth in the transfer case
and allow you to complete the
shift.
Shifting from Two-Wheel Drive
High to Four-Wheel Drive High
.Shifts between Two-Wheel Drive
High and Four-Wheel Drive High
can be made at any vehicle
speed.
.Shift the transfer case lever in
one continuous motion into
either the Four-Wheel Drive
High or Two-Wheel Drive High
position.
.Shifting from Two-Wheel Drive
High to Four-Wheel Drive High
while the vehicle is in motion
may require that moderate force
be applied to the shift lever for a
few seconds before Four-Wheel
Drive High can be engaged,
especially in cold weather.
.In extremely cold weather, it may
be necessary to slow or stop the
vehicle to shift into Four-Wheel
Drive High.
.While in Four-Wheel Drive High,
the vehicle can be driven at any
posted legal speed limit.

Low to Four-Wheel Drive High,
or Two-Wheel Drive High, the
vehicle must be stopped or
moving less than 5 km/h (3 mph)
with the transmission in N (Neutral)
and the ignition in ON/RUN.
The preferred method for shifting
out of Four-Wheel Drive Low is
to have the vehicle moving
1.6 to 3.2 km/h (1 to 2 mph).Turn the knob to the Four-Wheel
Drive High or Two-Wheel Drive
High position. You must wait for
the Four-Wheel Drive High or
Two-Wheel Drive High indicator light
to stop flashing and remain on
before shifting the transmission
into gear.
Notice:
Shifting the transmission
into gear before the requested
mode indicator light has stopped
flashing could damage the
