DVD Distortion
Video distortion can occur when
operating cellular phones, scanners,
CB radios, Global Position Systems
(GPS)*, two-way radios, mobile fax
machines, or walkie talkies.
It might be necessary to turn off the
DVD player when operating one of
these devices in or near the vehicle.
*Excludes the OnStar
®System.
Cleaning the RSE Overhead
Console
When cleaning the RSE overhead
console surface, use only a clean
cloth dampened with clean water.
Cleaning the Video Screen
When cleaning the video screen,
use only a clean cloth dampened
with clean water. Use care when
directly touching or cleaning the
screen, as damage could result.
Rear Seat Audio (RSA)
System
Vehicles with this feature allow
the rear seat passengers to listen
to and control any of the music
sources: radio, CDs, DVDs, or other
auxiliary sources. However, the rear
seat passengers can only control
the music sources the front seat
passengers are not listening to
(except on some radios where dual
control is allowed). For example,
rear seat passengers can control
and listen to a CD through the
headphones, while the driver
listens to the radio through the
front speakers. The rear seat
passengers have control of the
volume for each set of headphones.
The radio functionality is controlled
by both the RSA and the front radio.
Only one band can be tuned to at
one time. Changing the band on the
RSA or the front radio will change
the band on the other system,
if they are both sourced to the radio.The RSA functions can be used
even while the main radio is off.
The front audio system will display
the headphone icon when the RSA
is on, and it will disappear from the
display when the RSA is off.
Audio can be heard through wired
headphones (not included) plugged
into the jacks on the RSA. If the
vehicle has this feature, audio can
also be heard on Channel 2 of the
wireless headphones.
Depending on the audio system,
the rear speakers may continue to
play when the RSA audio is active
through the headphones.
To listen to an iPod or portable
audio device through the RSA,
attach the iPod or portable audio
device to the front auxiliary input
(if available), located on the front
audio system. Turn the iPod on,
then choose the front auxiliary input
with the RSA SRCE button.

Climate Controls 8-9
The passenger temperature
control cannot be activated while in
defrost mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger
temperature will not be displayed.
If vent, bi-level, or floor mode is
selected again, the climate control
system displays the previous
temperature settings.
Do not drive the vehicle until all
windows are clear.
#(Air Conditioning):Press
to turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on. If this button is pressed when
the air conditioning compressor
is unavailable due to outside
conditions, the indicator flashes
three times and then turns off.
If the air conditioning is on and the
outside temperature drops below a
temperature which is too cool for air
conditioning to be effective, the air
conditioning light turns off to show
that the air conditioning mode has
been canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
The air conditioning system
removes moisture from the air, so
a small amount of water might
drip under the vehicle while idling
or after turning off the engine.
This is normal.
@(Recirculation):
Press
to turn the recirculation mode on.
An indicator light comes on to show
that recirculation is on.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors
from entering the vehicle.
The recirculation mode cannot
be used with floor, defog, or
defrost modes. If recirculation is
selected with one of those modes,
the indicator light flashes three
times and then turns off. The air
conditioning compressor also comes
on when this mode is activated.
While in recirculation mode, the
windows may fog when the weather
is cold and damp. To clear the fog,
select either the defog or defrost
mode and increase the fan speed.

9-10 Driving and Operating
Traveling to Remote Areas
It makes sense to plan your trip,
especially when going to a remote
area. Know the terrain and plan
your route. Get accurate maps of
trails and terrain. Check to see if
there are any blocked or closed
roads.
It is also a good idea to travel with
at least one other vehicle in case
something happens to one of them.
For vehicles with a winch, be sure
to read the winch instructions. In a
remote area, a winch can be handy
if you get stuck but you will want to
know how to use it properly.
Getting Familiar with Off-Road
Driving
It is a good idea to practice in an
area that is safe and close to home
before you go into the wilderness.
Off-roading requires some new and
different skills.
Tune your senses to different kinds
of signals. Your eyes need to
constantly sweep the terrain for
unexpected obstacles. Your ears
need to listen for unusual tire or
engine sounds. Use your arms,
hands, feet, and body to respond
to vibrations and vehicle bounce.
Controlling the vehicle is the key to
successful off-road driving. One of
the best ways to control the vehicle
is to control the speed. At higher
speeds:
.You approach things faster and
have less time to react.
.There is less time to scan the
terrain for obstacles.
.The vehicle has more bounce
when driving over obstacles.
.More braking distance is
needed, especially on an
unpaved surface.
{WARNING
When you are driving off-road,
bouncing and quick changes in
direction can easily throw you
out of position. This could cause
you to lose control and crash.
So, whether you are driving on
or off the road, you and your
passengers should wear safety
belts.

Driving and Operating 9-37
C (ON/RUN):This position can
be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running. The transmission
is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the
ACC/ACCESSORY or ON/RUN
position with the engine off, the
battery could be drained. You may
not be able to start the vehicle if the
battery is allowed to drain for an
extended period of time.
D (START): This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning tone will sound when
the driver door is opened and the
ignition is in ACC/ACCESSORY or
LOCK/OFF, and the key is in the
ignition.Starting the Engine
If the vehicle has a Duramax diesel
engine, see the Duramax diesel
supplement for more information.
If the vehicle is a hybrid, see
the hybrid supplement for more
information.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly.
Any resulting damage would
not be covered by the vehicle
warranty.
Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go down as your engine gets
warm. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow
the oil to warm up and lubricate
all moving parts.

9-68 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor
or clicking noise might be heard
while this test is going on, and
it might even be noticed that
the brake pedal moves a little.
This is normal.If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑28.
If driving safely on a wet road
and it becomes necessary to
slam on the brakes and continue
braking to avoid a sudden obstacle,
a computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling,
the computer will separately
work the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard. As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.

Black plate (73,1)GMC Sierra Owner Manual - 2011
Driving and Operating 9-73
The traction control system may
activate on dry or rough roads
or under conditions such as
heavy acceleration while turning
or abrupt upshifts/downshifts of the
transmission. When this happens,
a reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when
the system activates, the StabiliTrak
light will flash and cruise control will
automatically disengage. Cruise
control may be reengaged when
road conditions allow. SeeCruise
Control on page 9‑73.
StabiliTrak may also turn off
automatically if it determines that
a problem exists with the system.
If the problem does not clear itself
after restarting the vehicle, see your
dealer for service. 2500 and 3500 series vehicles
with StabiliTrak have a Trailer Sway
Control (TSC) feature. See
Trailer
Sway Control (TSC) on page 9‑124.
2500 and 3500 series vehicles
with StabiliTrak have a Hill Start
Assist (HSA) feature. See Hill Start
Assist (HSA) on page 9‑70.
Adding non‐dealer accessories can
affect the vehicle's performance.
See Accessories and Modifications
on page 10‑3.
Locking Rear Axle
Vehicles with a locking rear axle can
give more traction on snow, mud,
ice, sand, or gravel. It works like a
standard axle most of the time, but
when traction is low, this feature will
allow the rear wheel with the most
traction to move the vehicle.
Cruise Control
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
For vehicles with cruise control, a
speed of about 40 km/h (25 mph)
or more can be maintained
without keeping your foot on the
accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).

When the System Does Not
Seem to Work Properly
The RVC system might not work
properly or display a clear image if:
.The RVC is turned off.
See“Turning the Rear Camera
System On or Off” earlier in this
section.
.It is dark.
.The sun or the beam of
headlights is shining directly
into the camera lens.
.Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
.The back of the vehicle is in an
accident. If this happens, the
position and mounting angle
of the camera can change or
the camera can be affected.
Be sure to have the camera
and its position and mounting
angle checked at your dealer.
The RVC system display in the
rearview mirror may turn off or not
appear as expected due to one
of the following conditions. If this
occurs the left indicator light on
the mirror will flash.
.A slow flash may indicate a
loss of video signal, or no video
signal present during the reverse
cycle.
.A fast flash may indicate that
the display has been on for the
maximum allowable time during
a reverse cycle, or the display
has reached an Over
Temperature limit.
The fast flash conditions are
used to protect the video
device from high temperature
conditions. Once conditions
return to normal the device will
reset and the green indicator
will stop flashing.
During any of these fault conditions,
the display will be blank and the
indicator will continue to flash as
long as the vehicle is in R (Reverse)
or until the conditions return to
normal.
Pressing and holding
zwhen the
left indicator light is flashing will turn
off the video display along with the
left indicator light.
