When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate tosevere frontal or near-frontal crashes to help reduce thepotential for severe injuries mainly to the driver’s orright front passenger’s head and chest. However, theyare only designed to inflate if the impact exceeds apredetermined deployment threshold. Deploymentthresholds are used to predict how severe a crash islikely to be in time for the airbags to inflate andhelp restrain the occupants.
Whether your frontal airbags will or should deploy is notbased on how fast your vehicle is traveling. It dependslargely 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 thevehicle hits a moving object.
•If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed thanif 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 speedthan 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 speedthan if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehiclerollovers, rear impacts, or in many side impacts.
Your vehicle has a seat position sensor which enablesthe sensing system to monitor the position of the rightfront passenger’s seat. The passenger seat positionsensor and passenger safety belt buckle switch provideinformation that is used to determine if the airbags shoulddeploy at a reduced level or at full deployment.
In addition, your vehicle has a dual-stage driver airbag.Dual-stage airbags adjust the restraint according tocrash severity. Your vehicle has electronic frontalsensors, which help the sensing system distinguishbetween a moderate frontal impact and a more severefrontal impact. For moderate frontal impacts, dual-stageairbags inflate at a level less than full deployment.For more severe frontal impacts, full deployment occurs.
2-63

Your vehicle also has a dual-depth passenger airbagthat adjusts the restraint according to crash severity,seat location, and safety belt status using electronicfrontal sensor(s) and other special sensors which enablethe sensing system to monitor the position of the frontpassenger seat. The passenger airbag inflates to areduced depth when the passenger seat is in a forwardposition. For more rearward front seating positions,the passenger airbag may inflate to an increased depth(a full deployment), based on safety belt status andthe crash severity measured early in the event. (Alwayswear your safety belt, even with frontal airbags.)
Your vehicle has seat-mounted side impact airbags.Your vehicle may have roof-rail airbags. SeeAirbagSystem on page 2-58. Seat-mounted side impact androof-rail airbags are intended to inflate in moderateto severe side crashes. Seat-mounted side impact androof-rail airbags will inflate if the crash severity isabove the system’s designed threshold level. Thethreshold level can vary with specific vehicle design.
Seat-mounted side impact and roof-rail airbags arenot intended to inflate in frontal impacts, near-frontalimpacts, rollovers, or rear impacts. A seat-mounted sideimpact airbag is intended to deploy on the side of thevehicle that is struck. Both roof-rail airbags willdeploy when either side of the vehicle is struck.
In any particular crash, no one can say whether anairbag should have inflated simply because of thedamage to a vehicle or because of what the repair costswere. For frontal airbags, inflation is determined bywhat the vehicle hits, the angle of the impact, and howquickly the vehicle slows down. For seat-mountedside impact and roof-rail airbags, deployment isdetermined by the location and severity of theside impact.

When the system check is complete, either the wordON or OFF, or the symbol for on or off, will be visible.SeePassenger Airbag Status Indicator on page 4-51.
The passenger sensing system turns off the rightfront passenger frontal airbag and seat-mounted sideimpact airbag under certain conditions. The driverairbags and the roof-rail airbags are not affected by thepassenger sensing system.
The passenger sensing system works with sensors thatare part of the right front passenger seat. The sensorsare designed to detect the presence of a properly-seatedoccupant and determine if the right front passengerfrontal airbag and seat-mounted side impact airbagshould be enabled (may inflate) or not.
According to accident statistics, children are safer whenproperly secured in a rear seat in the correct childrestraint 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-facingchild restraint; a child riding in a forward-facing childseat; 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-facingchild seat in the front.” This is because the risk tothe rear-facing child is so great, if the airbag deploys.
{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inflates. This is because the back of the
rear-facing child restraint would be very close to the
inflating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inflates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped), no
system is fail-safe. No one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are 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 changeabout the vehicle that could keep the airbagsfrom working properly?
A:Yes. If you add things that change your 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, or airbag wiring can
affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s 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).
SeePassenger Sensing System on page 2-67.

Object Detection Systems
Ultrasonic Front and Rear Parking
Assist (UFRPA)
For vehicles with the Ultrasonic Front and Rear ParkingAssist (UFRPA) system, it operates at speeds lessthan 8 km/h (5mph), and assists the driver with parkingand avoiding objects. It can determine how closeobjects are to the front bumper, up to 1.2 m (4 ft.) infront of the vehicle and the rear bumper, up to2.5 m (8 ft.) behind the vehicle. The distance sensorsare located on the front and rear bumper.
{WARNING:
The Ultrasonic Front and Rear Park Assist
(UFRPA) system does not replace driver vision.
It cannot detect:
•objects that are below the bumper,
underneath the vehicle, or if they are tooclose or far from the vehicle
•children, pedestrians, bicyclists, or pets.
If you do not use proper care before movingforward and while backing; vehicle damage, injury,or death could occur. Even with UFRPA, alwayscheck in front of the vehicle before moving forwardand behind the vehicle before backing up. Whilemoving forward and backing, be sure to look forobjects and check the vehicle’s mirrors.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporarycondition, the message PARK ASSIST OFF will bedisplayed on the DIC and a red light will be shown onthe rear URPA display when the shift lever is moved intoR (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, seeWashing Your Vehicle on page 6-95.
•A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during thelast drive cycle, the red light may illuminate inthe rear display. Once the attached object isremoved, 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 thecompression of air brakes on a very large truck.
If the system is still disabled after driving forward atleast 25 km/h (15 mph), take the vehicle to yourdealer/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.
{WARNING:
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 lanesmay result in damage to the vehicle, injury, ordeath. Always check the outside and rearviewmirrors, glance over your shoulder, and use theturn signal before changing lanes.
When the system detects a vehicle in the side blindzone, amber SBZA displays will light up in the sidemirrors. This indicates that it may be unsafe to changelanes. Before making a lane change, always checkthe SBZA display, check the outside and rearviewmirrors, look over your shoulder for vehicles andhazards, and use the turn signal.
3-43

SBZA Detection Zones
The SBZA sensor covers a zone of approximately onelane over from both sides of the vehicle, 3.5 m (11 ft).This zone starts at each side mirror and goes backapproximately 5 m (16 ft). The height of the zone isapproximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) offthe ground.
The SBZA detection zones do not change if the vehicleis towing a trailer. So be extra careful when changinglanes while towing a trailer.
How the System Works
When the vehicle is started, both outside mirror displayswill briefly come on to indicate that the system isoperating. While driving forward, the left or right sidemirror SBZA display will light up if a vehicle is detected inthat blind zone. If you activate a turn signal and a vehiclehas been detected on the same side, the SBZA displaywill flash to give you extra warning not to change lanes.
SBZA displays do not come on while the vehicle isapproaching or passing other vehicles. At speedsgreater then 20 mph (32 km/h), SBZA displays maycome on when a vehicle you have passed remains in ordrops back into the detection zone.
SBZA can be disabled through the Driver InformationCenter (DIC). SeeDriver Information Center (DIC)on page 4-61for more information. If the SBZAis disabled by the driver, the SBZA mirror displays willnot light up during normal driving.
