The passenger sensing system is designed to turn offthe right front passenger airbag and seat-mountedside impact airbag if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is present in
a rear-facing infant seat.
•The system determines that a small child is present
in a child restraint.
•The system determines that a small child is present
in a booster seat.
•A right front passenger takes his/her weight off of
the seat for a period of time.
•The right front passenger seat is occupied by a
smaller person, such as a child who has outgrownchild restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off theright front passenger frontal airbag and seat-mountedside impact airbag, the off indicator will light and stay litto remind you that the airbags are off. SeePassengerAirbag Status Indicator on page 4-51.
The passenger sensing system is designed to turn on(may inflate) the right front passenger frontal airbag andseat-mounted side impact airbag anytime the systemsenses that a person of adult size is sitting properly inthe right front passenger seat.
When the passenger sensing system has allowed theairbags to be enabled, the on indicator will light and staylit to remind you that the airbags are active.
For some children who have outgrown child restraintsand for very small adults, the passenger sensing systemmay or may not turn off the right front passenger frontalairbag and seat-mounted side impact airbag, dependingupon the person’s seating posture and body build.Everyone in the vehicle who has outgrown child restraintsshould wear a safety belt properly — whether or not thereis an airbag for that person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 4-50
for more information, including important safety
information.

Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on theseat during vehicle maneuvers and braking, whichhelps the passenger sensing system maintain thepassenger airbag status. See “Safety Belts” and“Child Restraints” in the Index for additional informationabout the importance of proper restraint use.
A thick layer of additional material, such as a blanket orcushion, or aftermarket equipment such as seatcovers, seat heaters, and seat massagers can affecthow well the passenger sensing system operates.We recommend that you not use seat covers or otheraftermarket equipment except when approved by GM foryour specific vehicle. SeeAdding Equipment to YourAirbag-Equipped Vehicle on page 2-73for moreinformation about modifications that can affect how thesystem operates.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.There are parts of the airbag system in several placesaround the vehicle. Your dealer/retailer and theservice manual have information about servicing thevehicle and the airbag system. To purchase a servicemanual, seeService Publications Ordering Informationon page 8-17.
{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 proper service
procedures, and make sure the person performing
work for you is qualified to do so.

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.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaboratebreak-in. But it will perform better in the long run ifyou follow these guidelines:
•Do not drive at any one constant speed, fast or
slow, for the first 500 miles (805 km). Do notmake full-throttle starts. Avoid downshifting tobrake or slow the vehicle.
•Avoid making hard stops for the first 200 miles
(322 km) or so. During this time the new brakelinings are not yet broken in. Hard stopswith new linings can mean premature wear andearlier replacement. Follow this breaking-inguideline every time you get new brake linings.
•Do not tow a trailer during break-in. SeeTowing
a Trailer on page 5-26for the trailer towingcapabilities of your vehicle and moreinformation.
Following break-in, engine speed and load can begradually increased.
