If the transmission is shifted 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. Close and latch the power
liftgate before driving.
If the liftgate is powered open and
the liftgate support struts have lost
pressure, the turn signals will flash
and a chime will sound. The liftgate
will stay open, and 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 full closed or open
position. After removing the
obstacle, the power liftgate
operation can be used again. If the
liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.After removing the obstacles, the
liftgate will resume normal power
operation.
The 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.
Setting the Power Liftgate
Intermediate Mode
To change the liftgate stop position:
1. Turn the liftgate switch to either
the MAX, or the ¾ mode position
and power open the liftgate.
2. Stop the liftgate movement at the desired height by pressing
any button that operates the
power liftgate, or the touchpad.
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.
When power opened with the
¾ mode selected, the liftgate stops
at the new set position.
If an audible and visual response is
not received when setting the
intermediate stop position, the
liftgate height is below the ¾ open
height minimum, approximately
5 feet at the edge of the liftgate.Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, turn the mode selector
switch to OFF.
With the power liftgate disabled and
all of the doors unlocked, the liftgate
can be manually opened and
closed. Manual operation of a
vehicle with a power liftgate requires
more effort than a standard
non-power liftgate.

3-34 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.
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
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 Systemon page 3‑30.
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 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, 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.

.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. SeeVehicle Data
Recording and Privacy
on
page 13‑17and Event Data
Recorders on page 13‑17.
.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 outboard
front passenger position. The
passenger airbag status indicator
will be visible on the instrument
panel when the vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. If the
vehicle has remote start, and it is
being used 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 5‑18. The passenger sensing system
turns off the outboard 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 outboard front passenger seat.
The sensors are designed to detect
the presence of a properly-seated
occupant and determine if the
outboard 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.

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 13‑14.
{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(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
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
