In addition, your vehicle has a dual-stage driver airbag.
Dual-stage airbags adjust the restraint according to
crash severity. Your 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 in ate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Your vehicle also has a dual-depth passenger airbag
that adjusts the restraint according to crash severity and
seat location using electronic frontal sensor(s) and other
special sensors which enable the sensing system to
monitor the position of the front passenger seat. The
passenger airbag in ates to a reduced depth when
the passenger seat is in a forward position. For more
rearward front seating positions, the passenger airbag
may in ate to an increased depth (a full deployment),
based on the crash severity measured early in the event.
(Always wear your safety belt, even with frontal airbags.)
Seat-mounted side impact and roof-rail airbags are
intended to in ate in moderate to severe side crashes.
In addition, these roof-rail airbags are intended to
in ate during a rollover or in a severe frontal impact.
Seat-mounted side impact and roof-rail airbags will
in ate if the crash severity is above the system’s
designed threshold level. The threshold level can
vary with speci c vehicle design.Seat-mounted side impact airbags are not intended to
in ate in frontal impacts, near-frontal impacts, rollovers,
or rear impacts. Roof-rail airbags are not intended to
in ate 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,
or in a severe frontal impact.
In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, in ation 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 passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbags are not part of the passenger
sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger’s
frontal airbag should be enabled (may in ate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
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 your 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.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag in ates. This is because
the back of the rear-facing child restraint
would be very close to the in ating airbag.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag if the system detects a rear-facing
child restraint, no system is fail-safe, and no
one can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured 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.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-17.
{CAUTION:
For up to 10 seconds after the ignition is turned
off and the battery is disconnected, an airbag
can still in ate during improper service. You
can be injured if you are close to an airbag when
it in ates. 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
quali ed 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, front sensors, side impact
sensors, rollover sensor module, or airbag wiring
can affect the operation of the airbag system.
1-70
In addition, your vehicle has 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 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 1-65.

If you shift the transmission out of PARK (P) while
the power function is in progress, the liftgate power
function will continue to completion. If you shift the
transmission out of PARK (P) 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 ash and a
chime will sound. The liftgate will hold open temporarily,
then slowly close. See your dealer 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 fully
closed or open position. After removing the obstruction,
the liftgate may be power opened or closed normally.
If the liftgate encounters multiple obstacles on the
same power cycle, the power function will deactivate,
and the liftgate will switch to manual operation.
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 fully open position or
close the liftgate to the fully closed and latched position.
The liftgate will now resume normal power operation.
Your vehicle has an obstacle detection sensor located
on the rear edge of the rear quarter panel windows. If an
object is caught between the liftgate and the window
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.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system, it helps you park easier
and avoid other vehicles while in REVERSE (R).
It operates at speeds less than 3 mph (5 km/h).
It can determine how close objects are to the rear
bumper, up to 5 feet (1.5 m) behind your vehicle.
The distance sensors are located on the rear bumper.
{CAUTION:
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.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and
while backing; vehicle damage, injury, or death
could occur. Even with URPA, always check
behind your vehicle before backing up. While
backing, be sure to look for objects and check
your vehicle’s mirrors.
The display is located
above the liftgate glass
and can be seen by
looking over your right
shoulder.
URPA uses three color-coded lights to provide
distance and system information.
