2004 Chevrolet Colorado Owner's Manual - Page 76

In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. • Let only qualified technicians work on your air bag system. Improper service can mean that your air bag system will not work properly. See your dealer for service. Notice: If you damage the covering for the driver's or the right front passenger's air bag, or the side impact air bag covering on the ceiling near the side windows, the bag may not work properly. You may have to replace the air bag module in the steering wheel, both the air bag module and the instrument panel for the right front passenger's air bag, or side impact air bag module and ceiling covering for the roof-mounted side impact air bag. Do not open or break the air bag coverings. • Air bags are designed to inflate only once. After an air bag inflates, you will need some new parts for your air bag system. If you do not get them, the air bag system will not be there to help protect you in another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts. • Your vehicle is equipped with electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. If your vehicle has side impact air bags, it also has electronic side sensors. Your vehicle is equipped with a crash sensing and diagnostic module, which records information about the air bag system. The module records information about the readiness of the system and when the system commands air bag inflation. It records the status of the driver's safety belt usage in a crash in which the air bag deploys or a crash in which the air bag nearly deploys. The module also records speed, engine rpm, brake and throttle data. 1-70
