Your vehicle is equipped with electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. Your vehicle is also equipped with a crash sensing and diagnostic module, which records information about the frontal air bag system. The module records information about the readiness of the system and when the system commands are 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. Let only qualified technicians work on your air bag systems. Improper service can mean that an air bag system won't work properly. See your dealer for service. Notice: If you damage the covering for the driver's or the right front passenger's airbag, the bag may not work properly. You may have to replace the air bag module in the steering wheel or both the air bag module and the instrument panel for the right front passenger's air bag. Do not open or break the air bag coverings.
