Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) 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 URPA system can be turned
on and off using the infotainment
system controls. See Vehicle
Personalization on page 5‑30 for
more information.

There is a minimum distance that
the power liftgate must already be
open for the system to hold it open.
If movement is stopped below that
minimum, the liftgate closes.
Do not force the liftgate open or
closed during a power cycle.
The power liftgate may be
temporarily disabled under
extreme temperatures or 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 latch is 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 turn signals flash and
a chime sounds. The liftgate stays
open temporarily, then slowly
closes. 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 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.
The MANUALLY CLOSE POWER
LIFTGATE warning message in the
Driver Information Center (DIC)
will display. After removing the
obstructions, the liftgate will resume
normal power operation.Pinch sensors are 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.Power Liftgate 3/4 Mode
To program the liftgate opening
height:
1. Turn the liftgate switch to either
the MAX, or the 3/4 mode
position and power open the
liftgate.
2. Stop the liftgate movement at the desired height by pressing
any liftgate switch. Manually
adjust the liftgate position if
required.
3. Press and hold the button on the liftgate adjacent to the latch until
the turn signals flash and a beep
sounds to indicate that the new
setting is recorded.

3-30 Seats and Restraints
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.
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 seat-mounted side
impact and roof-rail airbags. See
Airbag System on page 3‑26.
Seat-mounted side impact 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 and roof-rail airbags will
inflate if the crash severity is abovethe system's designed threshold
level. The threshold level can vary
with specific vehicle design.
Seat-mounted side impact airbags
are not intended to inflate in frontal
impacts, near-frontal impacts,
rollovers, or rear impacts. 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, 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

other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. SeeVehicle Data
Recording and Privacy on
page 13‑16 andEvent Data
Recorders on page 13‑16.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
on the overhead console when the
vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, are 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 5‑11. The passenger sensing system
turns off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat‐mounted side impact airbags
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. 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.

{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 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 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 has 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 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). See
Passenger Sensing System on
page 3‑33.
