1-24 In Brief
Side Blind Zone
Alert (SBZA)
If available, this feature will alert you
to vehicles located in the vehicle's
side blind zone. When the system
detects a vehicle in the side blind
zone, the SBZA display will light up
in the corresponding outside side
mirror.
The system can be disabled through
the Driver Information Center (DIC).
If the message SIDE BLIND ZONE
SYSTEM UNAVAILABLE appears
on the DIC, the system has been
disabled because the sensor is
blocked and cannot detect vehicles
in the blind zone. The sensor may
be blocked by mud, dirt, snow, ice,
slush, or even heavy rainstorms.
This message may also activate
during heavy rain or due to road
spray. The vehicle does not need
service.
SeeSide Blind Zone Alert (SBZA)
on page 9‑51 for more information.
Rear Vision
Camera (RVC)
If available, the RVC displays a view
of the area behind the vehicle when
the vehicle is shifted into
R (Reverse). The display will appear
on either the inside rearview mirror
or navigation screen, if equipped.
To clean the camera lens, located
above the license plate, rinse it with
water and wipe it with a soft cloth.
SeeRear Vision Camera (RVC) on
page 9‑53.
Ultrasonic Parking Assist
If available, this system uses
sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than
8 km/h (5 mph). URPA uses audible
beeps to provide distance and
system information. Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
See
Ultrasonic Parking Assist on
page 9‑50.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two under the climate
controls, one inside the center floor
console, one on the rear of the
center floor console and one
accessory power outlet in the rear
cargo area on the passenger side.
The accessory power outlets are
powered, even with the ignition off.
Continuing to use accessory power
outlets while the ignition is in LOCK/
OFF may cause the vehicle's
battery to run down.
See Power Outlets on page 5‑8.

Seats and Restraints 3-33
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
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.
In addition, the vehicle has
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 seat position sensors
which enable the sensing system to
monitor the position of the driver
seat and may or may not monitor
the position of the front
passenger seat.
The seat position sensor provides
information that is used to determine
if the airbags should deploy at a
reduced level or at full deployment.The vehicle may or may not have
seat-mounted side impact airbags.
The vehicle has roof-rail airbags.
See
Airbag System on page 3‑28.
Seat-mounted side impact airbags
and roof-rail airbags are intended to
inflate in moderate to severe side
crashes. In addition, these roof-rail
airbags are intended to inflate
during a rollover or in a severe
frontal impact. Seat-mounted side
impact airbags and roof-rail airbags
will inflate if the crash severity is
above the system's designed
threshold level. The threshold level
can vary with specific vehicle
design.
Roof-rail airbags are not intended to
inflate in rear impacts.
A seat-mounted side impact airbag
is intended to deploy on the side of
the vehicle that is struck. Both
roof-rail airbags will deploy when
either side of the vehicle is struck or
if the sensing system predicts that
the vehicle is about to roll over on
its side, or in a severe frontal
impact.

Seats and Restraints 3-37
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
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.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.We recommend that children be
secured in a rear seat, including: an
infant or a child riding in a
rear-facing child restraint; a child
riding in a forward-facing child seat;
an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says,
“Never put a rear-facing child seat in
the front.”
This is because the risk to
the rear-facing child is so great,
if the airbag deploys.
{WARNING
A child in a rear-facing child
restraint can be seriously injured
or killed if the right front
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
(Continued)
WARNING (Continued)
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
forward-facing child restraint in
the right front seat, always move
the front passenger seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.

{WARNING
For up to 10 seconds after the
vehicle 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 the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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,
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 seat heater or a
comfort enhancing pad or
device, installed under or on topof 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). See
Passenger Sensing System on
page 3‑36.

roof-rail airbags, seeDifferent
Size Tires and Wheels on
page 10‑59 for 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
