When Should an Airbag Inate? Frontal airbags are designed to inate 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 inate 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 inate and
help restrain the occupants.
Whether your 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 inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object does not deform.
If the vehicle hits a narrow object (like a pole), the
airbags could inate 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 inate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specic vehicle design.
Frontal airbags are not intended to inate during vehicle
rollovers, rear impacts, or in many side impacts.
In addition, your 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 inate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Your vehicle has a seat position sensor which enables
the sensing system to monitor the position of the driver’s
seat. The seat position sensor provides information
that is used to determine if the airbags should deploy at
a reduced level or at full deployment.
Your vehicle has roof-rail airbags. See Airbag System
on page 1-79 . Roof-rail airbags are intended to inate in
moderate to severe side crashes. In addition, these
roof-rail airbags are intended to inate during a rollover
or in a severe frontal impact. Roof-rail airbags will
inate if the crash severity is above the system’s
designed threshold level. The threshold level can vary
with specic vehicle design.

The passenger sensing system works with sensors that
are part of the right front passenger seat and safety
belt. 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 inate) 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. { CAUTION: A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though the airbag is turned off.
Secure rear-facing child restraints 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.

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 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 1-87 .

Customer Satisfaction Procedure in this manual.
See Customer Satisfaction Procedure on page 8-2 .
If the vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels on page 6-73 for
additional important information.
Q: Because I have a disability, I have to get my
vehicle modied. How can I nd 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. See
Customer Satisfaction Procedure on page 8-2 .

The power liftgate can be power opened and closed in
the following ways:
Press and hold the power liftgate button on the
Remote Keyless Entry (RKE) transmitter until
the liftgate starts moving. Remote Keyless Entry
(RKE) System Operation on page 2-5 for more
information.
Pressing the liftgate button on the overhead
console.
Pressing the touchpad switch on the outside liftgate
handle.
Pressing the buttons, or touchpad switch a second time
while the liftgate is moving reverses the direction.
l : The liftgate can also be closed by pressing the
power liftgate button next to the liftgate latch.
Press the button a second time during liftgate operation
to reverse that operation.
The power liftgate may be temporarily disabled under
extreme temperatures, or under low battery conditions.
If this occurs, the liftgate can still be operated manually.
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 stay open temporarily, then
slowly close. See your dealer/retailer 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, and you must manually
open or close the liftgate. 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 full open
position or close the liftgate to the fully closed and latched
position. The liftgate will now resume normal power
operation.
Your 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.

mirrors.
See “Rear Window Defogger” under Dual Automatic
Climate Control System on page 3-27 for more
information.
Object Detection Systems Ultrasonic Rear Parking
Assist (URPA) For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than 5 mph
(8 km/h), and assists the driver with parking and avoiding
objects while in R (Reverse). The sensors on the rear
bumper are used to detect the distance to an object up to
8 feet (2.5 m) behind the vehicle, and at least 10 inches
(25.4 cm) off the ground. { 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.
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle’s mirrors.
2-42

When the System Does Not Seem to
Work Properly If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 6-100 .
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the liftgate during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at least
15 mph (25 km/h), take the vehicle to your dealer/retailer. Side Blind Zone Alert (SBZA) The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the system.

The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modications to
this equipment. Such modications could void the user’s
authority to operate the equipment.
{ CAUTION: SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
Vehicles outside the side blind zones which
may be rapidly approaching.
Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury, or
death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind zone,
amber SBZA displays light up in the side mirrors. This
indicates that it may be unsafe to change lanes. Before
making a lane change, always check the SBZA display,
check the outside and rearview mirrors, look over your
shoulder for vehicles and hazards, and use the turn
signal. SBZA Detection Zones The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 11 ft. or 3.5 m.
This zone starts at each side mirror and goes back
approximately 16 ft. (5.0 m). The height of the zone is
approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off
the ground.
Use caution while changing lanes when towing a trailer,
as the SBZA detection zones do not change when a
trailer is towed.
2-45

SBZA does not operate when the left or right corners
of the rear bumper are covered with mud, dirt, snow,
ice, slush, or in heavy rainstorms. For cleaning
instructions, see Washing Your Vehicle on page 6-100 .
If the DIC still displays the SIDE BLIND ZONE SYSTEM
UNAVAILABLE message after cleaning the bumper, see
your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn SBZA
back on using the DIC. The SIDE BLIND ZONE ALERT
ON option will not be selectable if the conditions for
normal system operation are not met. Until normal
operating conditions for SBZA are met, you should not
rely upon SBZA while driving. SBZA Error Messages The following messages may appear in the DIC:
SIDE BLIND ZONE ALERT SYSTEM OFF: This
message indicates that the driver has turned the
system off.
SIDE BLIND ZONE SYSTEM UNAVAILABLE: This
message indicates that the SBZA system is disabled
either because the sensor is blocked and cannot detect
vehicles in your blind zone, or the vehicle is passing
through an open eld of view area, such as the desert,
where there is insufficient data for operation. The sensor
may be blocked by mud, dirt, snow, ice, slush, or even
heavy rainstorms. This message may also activate during
heavy rain or due to road spray. The vehicle does not
need service. For cleaning, see Washing Your Vehicle on
page 6-100 .
SERVICE SIDE BLIND ZONE ALERT SYSTEM: If this
message appears, both SBZA displays will remain on
indicating there is a problem with the SBZA system.
If these displays remain on after continued driving, the
system needs service. Take the vehicle to your
dealer/retailer.
2-47

Rainsense™ II Wipers The vehicle has Rainsense™ II windshield wipers.
These wipers automatically turn on when a sensor,
mounted next to the inside rearview mirror, detects
moisture on the windshield. When active, these wipers
are able to detect moisture on the windshield and
automatically turn on the wipers.
To turn on the Rainsense™ feature, the wipers must
be set to one of the ve delay settings. Each of the
ve settings adjusts the sensitivity of the rain sensor.
Since different drivers have different setting preferences,
it is recommended that the mid-range setting, position
three, be used initially. For more wipes, select the higher
settings; for fewer wipes, select the lower settings located
closer to the off position on the multifunction lever. The rain sensor will automatically control the frequency
of the wipes from off to high speed according to the
weather conditions. The wipers can be left in a
Rainsense™ mode even when it is not raining.
When Rainsense™ II is active, the headlamps will
turn on automatically after approximately eight wipes.
The headlamps will turn off if the wiper switch is set
to a delay position, and there have been no wipes for
approximately three minutes, or if the wiper switch
is turned to the off position. If it is dark outside, the
headlamps will remain on.
Notice: Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.

IntelliBeam ®
Intelligent High-Beam
Headlamp Control System For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam ®
is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor on the
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam ®
system turns the high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the IntelliBeam ®
system is enabled.
Turning On and Enabling IntelliBeam ®
Press and release the IntelliBeam ®
button on the inside
rear view mirror. The IntelliBeam ®
indicator on the mirror
will turn on to let you know the system has been turned
on. Once the system has been turned on, it will remain
on each time the vehicle is started. Additionally, the
IntelliBeam ®
system must be enabled.
To enable the IntelliBeam ®
system, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
will appear on the instrument panel cluster when
the high-beams are on. See Highbeam On Light
on page 3-46 . Driving with IntelliBeam ®
IntelliBeam ®
will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will remain on, under the
automatic control of IntelliBeam ®
, until any of the
following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
The vehicle’s speed drops below 15 mph (24 km/h).
The headlamp stalk is moved forward to the
high-beam position. See Headlamp High/Low-Beam
Changer on page 3-8 .
When either of these conditions occur, the
IntelliBeam ®
feature will be disabled and the
IntelliBeam ®
light in the mirror will turn off until the
high-beam stalk is returned to the neutral position.
If IntelliBeam ®
was using low-beams prior to
this action, the IntelliBeam ®
feature will be
temporarily disabled until the stalk is returned
to the neutral position.
