Side Blind Zone Alert (SBZA)
This feature may alert you to vehicles located in your
side blind zone. When the system detects a vehicle in
the side blind zone, an amber SBZA display will light up
in the corresponding outside side mirror.
The system is enabled at every vehicle startup. It can
be disabled through the Driver Information Center (DIC).
If the message SIDE BLIND ZONE SYS.
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.
See Side Blind Zone Alert (SBZA)
on page 3‑47for
more information.
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 lense, located above the license
plate, rinse it with water and wipe it with a soft cloth.

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.
The vehicle has a seat position sensor. Vehicles with
dual stage airbags also have seat position sensors
which enable the sensing system to monitor the
position of the driver 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 2‑75. 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 veicle 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, or in a severe frontal
impact.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation is determined by what
the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat‐mounted side
impact and roof-rail airbags, deployment is determined
by the location and severity of the side impact. In a
rollover event, roof-rail airbag deployment is determined
by the direction of the roll.

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, if equipped, to start the vehicle from a
distance, 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 4‑29.
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.

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 the 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
position, which includes sensors that are part of the
passenger 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
2-91

different vehicle. Any object, such as an aftermarket
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, 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.
If the vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels
on page 6‑75for
additional important information. 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.

The power liftgate may be temporarily disabled under
extreme temperatures, or under low battery conditions.
If this occurs, the liftgate can still be operated manually.
If you shift the transmission out of P (Park) while the
power function is in progress, the liftgate power function
will continue to completion. If you shift the transmission
out of P (Park) and accelerate before the power liftgate
latches closed, the liftgate may reverse to the open
position. Cargo could fall out of the vehicle. Always
make sure the power liftgate is closed and latched
before you drive away.
If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will flash and a
chime will sound. The liftgate will stay open temporarily,
then slowly close. See your dealer/retailer for service
before using the liftgate.Obstacle Detection Features
If the liftgate encounters an obstacle during a power
open or close cycle, a warning chime will sound and the
liftgate will automatically reverse direction to the full
closed or open position. After removing the obstruction,
the power liftgate operation can be used again. If the
liftgate encounters multiple obstacles on the same
power cycle, the power function will deactivate, and you
must manually open or close the liftgate. The REAR
ACCESS OPEN warning message in the Driver
Information Center (DIC) will indicate that the liftgate is
open. After removing the obstructions, manually open
the liftgate to the full open position or close the liftgate
to the fully closed and latched position. The liftgate will
now resume normal power operation.
Your vehicle has pinch sensors located on the side
edges of the liftgate. If an object is caught between
the liftgate and the body and presses against this
sensor, the liftgate will reverse direction and open fully.
The liftgate will remain open until it is activated again or
closed manually. Do not force the liftgate open or closed
during a power cycle.
