The passenger sensing system isdesigned to turn on the frontoutboard passenger frontal airbagand knee airbag anytime the systemsenses that a person of adult size issitting properly in the front outboardpassenger seat. When the
passenger sensing system hasallowed the airbags to be enabled,the on indicator will light and stay litas a reminder that the airbags areactive.
For some children who haveoutgrown child restraints, and forvery small adults, the passengersensing system may or may not turnoff the front outboard passengerfrontal airbag and knee airbag,depending upon the person'sseating posture and body build.Everyone in the vehicle who hasoutgrown child restraints shouldwear a safety belt properly—whether or not there is an airbag forthat 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

Additional Factors Affecting
System Operation
Safety belts help keep thepassenger in position on the seatduring vehicle maneuvers andbraking, which helps the passengersensing system maintain thepassenger airbag status. See“Safety Belts”and“Child Restraints”in the Index for additionalinformation about the importance ofproper restraint use.
Athicklayerofadditionalmaterial,such as a blanket or cushion,or aftermarket equipment such asseat covers, seat heaters, and seatmassagers can affect how well thepassenger sensing systemoperates. We recommend that younot use seat covers or otheraftermarket equipment except whenapproved by GM for your specific
vehicle. SeeAdding Equipment tothe Airbag-Equipped Vehicle075for more information aboutmodifications that can affect howthe system operates.
The on indicator may be lit if anobject, such as a briefcase,handbag, grocery bag, laptop,or other electronic device, is put onan unoccupied seat. If this is notdesired, remove the object fromthe seat.
{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 the
Airbag-Equipped Vehicle
Airbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Your
dealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation0316.
{Warning
For up to 10 seconds after the
vehicle 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 the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal may keep the airbag system

This system is designed to makethe installation of child restraintseasier. When using lower anchors,do not use the vehicle's safety belts.Instead, use the vehicle's anchorsand child restraint attachments to
secure the restraints. Somerestraints also use another vehicleanchor to secure a top tether.
1. Attach and tighten the lowerattachments to the loweranchors. If the child restraintdoes not have lowerattachments or the desiredseating position does not havelower anchors, secure the childrestraint with the top tether andthe safety belts. Refer to yourchild restraint manufacturerinstructions and theinstructions in this manual.
1.1. Find the lower anchorsfor the desired seatingposition.
1.2. Put the child restraint onthe seat.
