Navigation System
If the vehicle has a navigation
system, there is a separate
infotainment manual that includes
information on the radio, audio
players, and navigation system.
The navigation system provides
detailed maps of most major
freeways and roads. After a
destination has been set, the
system provides turn-by-turn
instructions for reaching the
destination. In addition, the system
can help locate a variety of points of
interest (POIs), such as banks,
airports, restaurants, and more.
Rear Vision
Camera (RVC)
If equipped, 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.
See
Rear Vision Camera (RVC) on
page 9-39.
Ultrasonic Parking Assist
If equipped, 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). Ultrasonic Rear
Parking Assist (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 9-38.

3-20 Seats and Restraints
When Should an Airbag
Inflate?
This vehicle is equipped with one or
more airbags. SeeAirbag System
on page 3-16. Airbags are designed
to inflate if the impact exceeds the
specific airbag system's 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. The vehicle has
electronic sensors which help the
airbag system determine the
severity of the impact. Deployment
thresholds can vary with specific
vehicle design.
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 or front
outboard passenger head and
chest.
Whether the frontal airbags will or
should deploy is not based primarily
on how fast the vehicle is traveling. It depends largely on what you hit,
the direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable, narrow
or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
In addition, if the GVWR (Gross
Vehicle Weight Rating) is 3 855 kg
(8,500 lb) or below, the vehicle has
advanced technology frontal
airbags. You can find the GVWR on
the Certification/Tire label on the
rear edge of the driver door. See
Vehicle Load Limits on page 9-10.
Advanced technology frontal airbags
adjust the restraint according to
crash severity.
The vehicle may or may not be
equipped with roof-rail airbags.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location
of the impact. In addition, these
roof-rail airbags are designed to
inflate during a rollover. Roof-rail
airbags are not designed to inflate in
frontal, near-frontal, or rear impacts.
All roof-rail airbags will inflate 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.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
vehicle damage or repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover. The inflator, the airbag,
and related hardware are all part of
the airbag module.

The passenger airbag status
indicator will be visible on the
instrument panel when the vehicle is
started.
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or the word OFF, or the
symbol for on or the symbol for off,
will be visible. See Passenger
Airbag Status Indicator on
page 5-17. The passenger sensing system will
turn off the front outboard
passenger frontal airbag under
certain conditions. No other airbag
is affected by the passenger
sensing system.
The passenger sensing system
works with sensors that are part of
the front outboard passenger seat.
The sensors are designed to detect
the presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag
should be allowed to 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.
Whenever possible, children age
12 and under should be secured in
a rear seating position.
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 passenger frontal
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
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
inflate under some unusual
circumstance, even though the
airbag is off.

approved by GM for your specific
vehicle. SeeAdding Equipment to
the Airbag-Equipped Vehicle on
page 3-30 for more information
about modifications that can affect
how the system operates.
The on indicator may be lit if an
object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on an
unoccupied seat. If this is not
desired remove the object from
the seat.
{Warning
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
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 and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13-11.
{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
(Continued)
Warning (Continued)
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal, may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing any
parts of the front seats, safety belts,
the airbag sensing and diagnostic
module, steering wheel, instrument
panel, any airbag modules, ceiling
or pillar garnish trim, front sensors,
rollover sensor module, or airbag
wiring.

Seats and Restraints 3-31
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle may have a
passenger sensing system for the
front outboard 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 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 properlyturning off the passenger airbag(s).
See
Passenger Sensing System on
page 3-25.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels on page 10-65 for
additional important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
