Keys, Doors and Windows 2-11
If the transmission is shifted out of
P (Park) while the power function is
in progress, the liftgate power
function will continue to completion.
If the transmission is shifted out of
P (Park) and the vehicle accelerates
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 flash and a
chime will sound. The liftgate will
stay open temporarily, then slowly
close. See your dealer/retailer for
service before using the liftgate if
this occurs.
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 orclose 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. See
Driver
Information Center (DIC)
on
page 5‑25for 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.
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. 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 the OFF position.
With the power liftgate disabled and
all of the doors unlocked, the liftgate
can be manually opened and
closed.

Seats and Restraints 3-33
When Should an Airbag
Inflate?
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's or right
front passenger's head and chest.
However, they are only designed to
inflate if the impact exceeds a
predetermined 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.
Whether the frontal airbags will or
should deploy is not based on how
fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.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 Systemon page 3‑29.
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.

Seats and Restraints 3-37
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
Canada
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 5‑17.
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.

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 3‑37.
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 10‑54for 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.

Daytime Running Lamps
(DRL)/Automatic
Headlamp System
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
A light sensor on top of the
instrument panel makes the DRL
work, so do not cover the sensor.The DRL system's automatic control
makes the DRL lights come on
when the following conditions
are met:
.The ignition is in the ON/RUN
position.
.The exterior lamps control is
in AUTO.
.The engine is running.
When the DRL are on, only the DRL
lights will be on. The headlamps,
taillamps, sidemarker, and other
lamps will not be on. The instrument
panel and cluster will also not be lit.
When it is dark enough outside, the
DRL lights will turn off and the
headlamps and parking lamps will
turn on. The other lamps that come
on with the headlamps will also
come on.
When it is bright enough outside,
the headlamps will go off and the
DRL will come on.
The regular headlamp system
should be turned on when it is
needed.
Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when the
headlamps are on due to the
automatic headlamps control
feature, and when the ignition is
turned off. The headlamps remain
on until the exterior lamps control is
moved to the parking lamps position
or until the pre-selected delayed
headlamp lighting period has ended.
If the ignition is turned off with the
