Obstacle Detection Features
A warning chime will sound and the
liftgate will automatically reverse
direction to the full closed or open
position if the liftgate encounters an
obstacle during a power open or
close cycle. After removing the
obstruction, the power liftgate
operation can be used again.
If the liftgate comes across more
obstacles on the same power cycle,
the power function deactivates, and
you must manually open or close
the liftgate. A message displays,
LIFTGATE OPEN, to indicate that
the liftgate is open. SeeDriver
Information Center (DIC) (With DIC
Buttons)
on page 5‑23or Driver
Information Center (DIC) (Without
DIC Buttons)
on page 5‑28for
more information. 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
resumes normal power operation. Pinch sensors are located on the
side edges of the liftgate. If an
object is caught between the liftgate
and the vehicle 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.
Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, press the switch on the
center console to OFF.
With the power liftgate disabled and
all of the doors unlocked, the liftgate
can be manually opened and
closed.
To open the liftgate, press the
touchpad on the handle on the
outside of the liftgate and lift the
gate open. To close the liftgate, use
the pull cup to lower the liftgate and
close. The liftgate latch will power
close. Always close the liftgate
before driving.
If the RKE button or the power close
button on the liftgate is pressed
while power operation is disabled,
the lights will flash three times, but
the liftgate will not move.
It is not recommended that you
drive with the liftgate open.
However, if you must drive with the
liftgate open, the liftgate should be
set to manual operation by pressing
the OFF switch on the center
console.

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.
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 3‑30.
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.
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

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 instrument panel when the
vehicle is started.
United States
CanadaThe 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 5‑15.
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.
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.

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 3‑38.
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.
If the vehicle has rollover
roof-rail airbags, see
Different
Size Tires and Wheels
on
page 10‑53for 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.
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.

5-10 Instruments and Controls
The indicator light does not come on
when the ignition is in LOCK/OFF or
if no equipment is plugged into the
outlet.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the Remote
Accessory Power (RAP) off and
then back on. SeeRetained
Accessory Power (RAP)
on
page 9‑17. The power restarts
when equipment using 150 watts or
less is plugged into the outlet and a
system fault is not detected. The power outlet is not designed for
the following electrical equipment
and may not work properly if these
items are plugged into the power
outlet:
.Equipment with high initial peak
wattage such as:
compressor-driven refrigerators
and electric power tools.
.Other equipment requiring an
extremely stable power supply
such as:
microcomputer-controlled
electric blankets, touch sensor
lamps, etc.
See High Voltage Devices and
Wiring on page 10‑30.
Warning Lights,
Gages, and Indicators
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gages can indicate when there
could be a problem with a vehicle
function. Often gages and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.
