Vehicle Customization
Some vehicle features can be
programmed by using the DIC
buttons next to the steering wheel.
These features include:
.Language
.Door Lock and Unlock Settings
.RKE Lock and Unlock Feedback
.Lighting
.Chime Volume
.Memory Features
See Vehicle Personalization (with
DIC Buttons) on page 5‑52.
Rear Vision
Camera (RVC)
If available, the rear vision camera
displays a view of the area behind
the vehicle when the vehicle is
shifted into R (Reverse). This is
displayed on the inside rearview
mirror or the navigation screen,
if equipped.
To clean the camera lens, located
in the bezel for the tailgate handle,
rinse it with water and wipe it with
a soft cloth.
For more information, see Rear
Vision Camera (RVC) on page 9‑78.
Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) uses sensors on the
rear bumper to detect objects while
parking the vehicle. URPA comes
on automatically when the shift
lever is moved into R (Reverse) and
operates at speeds less than 8 km/h
(5 mph). URPA uses audio beeps
to provide distance and system
information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
The system can be disabled by
pressing the rear park aid disable
button located next to the radio.
See Ultrasonic Parking Assist on
page 9‑76 for more information.

Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection, your dealer can
prepare the vehicle for
inspection.
Brake System Warning
Light
With the ignition on, the brake
system warning light comes on
when the parking brake is set. If the
vehicle is driven with the parking
brake engaged, a chime sounds
when the vehicle speed is greater
than 8 km/h (5 mph).
The vehicle brake system
consists of two hydraulic circuits.
If one circuit is not working, the
remaining circuit can still work to
stop the vehicle. For normal braking
performance, both circuits need to
be working
If the warning light comes on and
a chime sounds there could be a
brake problem. Have the brake
system inspected right away.

Fuel System Messages
FUEL LEVEL LOW
This message displays and a
chime may sound if the fuel level
is low. Refuel as soon as possible.
SeeFuel Gauge on page 5‑15
and Fuel on page 9‑84 for more
information.
TIGHTEN GAS CAP
This message may display along
with the check engine light on
the instrument panel cluster if the
vehicle's fuel cap is not tightened
properly. See Malfunction Indicator
Lamp on page 5‑25. Reinstall
the fuel cap fully. See Filling the
Tank on page 9‑88. The diagnostic
system can determine if the fuel
cap has been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into the
atmosphere. A few driving trips with
the cap properly installed should
turn this light and message off.
Key and Lock Messages

Ride Control System
Messages
SERVICE STABILITRAK
If the vehicle has StabiliTrak and
this message displays, it means
there may be a problem with the
StabiliTrak system. If you see this
message, try to reset the system. Stop; turn off the engine for at least
15 seconds; then start the engine
again. If this message still comes
on, it means there is a problem.
You should see your dealer for
service. The vehicle is safe to
drive; however, you do not have
the benefit of StabiliTrak, so reduce
your speed and drive accordingly.
SERVICE TRACTION
CONTROL
If the vehicle has StabiliTrak, this
message displays when there is a
problem with the Traction Control
System (TCS). When this message
displays, the system will not limit
wheel spin. Adjust your driving
accordingly. See your dealer for
service. See
StabiliTrak
®System on
page 9‑70 for more information.
STABILITRAK OFF
If the vehicle has StabiliTrak, this
message displays when you turn
off StabiliTrak, or when the stability
control has been automatically
disabled. To limit wheel spin
and realize the full benefits of
the stability enhancement system,
you should normally leave
StabiliTrak on. However, you
should turn StabiliTrak off if your
vehicle gets stuck in sand, mud, ice,
or snow and you want to rock your
vehicle to attempt to free it, or if
you are driving in extreme off-road
conditions and require more wheel
spin. SeeIf the Vehicle is Stuck on
page 9‑23. To turn the StabiliTrak
system on or off, see StabiliTrak
®
System on page 9‑70.

9-20 Driving and Operating
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑57.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, find
a safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Black plate (36,1)GMC Sierra Owner Manual - 2011
9-36 Driving and Operating
A (STOPPING THE ENGINE/
LOCK/OFF):When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑40.
This position locks the ignition.
It also locks the transmission on
automatic transmission vehicles.
The key can be removed in
LOCK/OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags. In an emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑69. The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
Notice:
Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer.
B (ACC/ACCESSORY): This
position lets things like the radio
and the windshield wipers operate
while the engine is off. Use this
position if the vehicle must be
pushed or towed.
