If the shoulder portion of the belt is pulled out all the
way, the child restraint locking feature will be engaged.
This may unintentionally cause the passenger sensing
system to turn the airbag off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat covers,
seat heaters, and seat massagers can affect how well the
passenger sensing system operates. We recommend
that you not use seat covers or other aftermarket
equipment except when approved by GM for your speci c
vehicle. SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 1-76for more information about
modi cations that can affect how the system operates.
{CAUTION:
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 places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
in ate during improper service. You can be injured
if you are close to an airbag when it in ates. 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 quali ed to do so.
