2010 GMC SIERRA sensor

Rear Vision Camera (RVC)
The rear vision camera displays a view of the area
behind the vehicle when the vehicle is shifted into
R (Reverse) on the inside rear view 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, seeRear Vision Camera (RVC)
on page 3‑63.
Ultrasonic Parking Assist
This feature 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.

Power Outlets
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
The vehicle may have two accessory power outlets
located below the climate control system, or may have
one accessory power outlet and one cigarette lighter.
The cigarette lighter is designed to fit only in the
receptacle closest to the driver.
There may be another accessory power outlet in the
rear cargo area. If the vehicle has a floor console, there
is an accessory power outlet inside the storage bin and
one on the rear of the floor console.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use power
outlets while the ignition is in LOCK/OFF may cause the
vehicle's battery to run down.

When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce the
potential for severe injuries mainly to the driver's or right
front passenger's head and chest. However, they are
only designed to inflate if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash is
likely to be in time for the airbags to inflate and help
restrain the occupants.
Whether the frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact, and
how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds.
For example:
.If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
.If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed
than if the vehicle hits an object that does not
deform.
.If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
.If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, the vehicle has
single stage airbags. If the GVWR is below 8,500 lb
(3 855 kg) then the vehicle has dual stage airbags. You
can find the GVWR on the certification label on the rear
edge of the driver's door. See Loading the Vehicle
on
page 5‑30for more information.
The vehicle may have dual‐stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. The vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
Vehicles with dual stage airbags also have a driver's
seat position sensor which enables the sensing system
to monitor the position of the driver seat (all models).
The seat position sensor provides information that is
used to determine if the airbags should deploy at a
reduced level or at full deployment.

Passenger Sensing System
If the vehicle has one of the indicators pictured in the
following illustrations, then the vehicle has a passenger
sensing system for the right front passenger position,
unless there is an airbag off switch located in the glove
box. If there is an airbag off switch, the vehicle does not
have a passenger sensing system. SeeAirbag Off
Switch
on page 2‑82for more information.
The passenger airbag status indicator will be visible on
the overhead console when the vehicle is started.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refers to “ADVANCED
AIRBAGS”.United StatesCanada
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are
using remote start to start the vehicle from a distance,
if equipped, you may not see the system check.
When the system check is complete, either the word
ON or OFF, or the symbol for on or off, will be visible.
See Passenger Airbag Status Indicator on page 4‑36.
The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag, seat‐mounted side impact airbags
(if equipped), and the roof-rail airbags (if equipped) are
not affected by the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat and safety
belt. The sensors are designed to detect the presence
of a properly-seated occupant and determine if the
right front passenger frontal airbag should be enabled
(may inflate) or not.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the service
manual have information about servicing the vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information
on
page 8‑16.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change about the vehicle that could keep the airbags from
working properly?
A: Yes. If you add things that change your vehicle's
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, rollover sensor module, or airbag
wiring can affect the operation of the airbag system.
In addition, the vehicle may have a passenger
sensing system for the right front passenger's
position, which includes sensors that are part of the
passenger's seat. The passenger sensing system
may not operate properly if the original seat trim is
replaced with non-GM covers, upholstery or trim,
or with GM covers, upholstery or trim designed for a
different vehicle. Any object, such as an aftermarket
2-91

seat heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could
also interfere with the operation of the passenger
sensing system. This could either prevent proper
deployment of the passenger airbag(s) or prevent
the passenger sensing system from properly turning
off the passenger airbag(s). SeePassenger Sensing
System on page 2‑85.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses
for Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
See Customer Satisfaction Procedure on page 8‑2.
If the vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels
on page 6‑85for
additional important information. Q: What if I added a snow plow? Will it keep the
airbags from working properly?
A: We have designed our airbag systems to work
properly under a wide range of conditions, including
snow plowing with vehicles that have the optional
Snow Plow Prep Package (RPO VYU). But do not
change or defeat the snow plow's “tripping
mechanism.” If you do, it can damage your snow
plow and your vehicle, and it may cause an airbag
inflation.
Q: Because I have a disability, I have to get my vehicle modified. How can I find out whether this
will affect my airbag system?
A: If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 8‑2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than
8 km/h (5 mph), and assists the driver with parking and
avoiding objects while in R (Reverse). The sensors on
the rear bumper are used to detect the distance to an
object up to 2.5 m (8 ft) behind the vehicle, and at least
25.4 cm (10 in) off the ground.
{WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
.Objects that are below the bumper,
underneath the vehicle, or if they are too close
or far from the vehicle
.Children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle's mirrors.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the messages PARK ASSIST OFF or PARK
ASST BLOCKED SEE OWNERS MANUAL will be
displayed on the DIC.
SERVICE PARK ASSIST :If this message occurs, take
the vehicle to your dealer/retailer to repair the system.
PARK ASSIST OFF : This message occurs if the driver
disables the system.
PARK ASST BLOCKED SEE OWNERS MANUAL :
This message can occur under the following conditions:
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, see Washing
Your Vehicle on page 6‑113.
.The park assist sensors are covered by frost or
ice. Frost or ice can form around and behind the
sensors and may not always be seen; this can
occur after washing the vehicle in cold weather.
The message may not clear until the frost or ice
has melted.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
last drive cycle. Once the attached object is
removed and the tailgate is raised, URPA will
return to normal operation.
.A tow bar is attached to the vehicle.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 40 km/h (25 mph), take the vehicle to your
dealer/retailer.
