Restraint System Check Checking the Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Also look for any opened or broken airbag covers, and have them repaired or replaced. (The airbag system does not need regular maintenance.) Notice: If you damage the covering for the driver's or the right front passenger's airbag, or the side impact airbag covering (if equipped) on the ceiling near the side windows, the airbag may not work properly. You may have to replace the airbag module in the steering wheel, both the airbag module and the instrument panel for the right front passenger's airbag, or side impact airbag module and ceiling covering for roof-mounted side impact airbags (if equipped.) Do not open or break the airbag coverings. 1-73
