Service Precautions

Observe these precautions when working on steering columns with air bag systems:

• Never use test light, ohmmeter or voltmeter to test air bag system, except when testing spiral spring. System can only be tested using Scan Tool (VAG 1551/1552), Vehicle Diagnostic, Testing and Information System (VAS 5051) or equivalent scan tool, with appropriate adapter. DO NOT use Air Bag Tester (VAG 1619).
• Air bag system components must never be opened, disassembled or repaired. Always use new parts.
• Air bag system components have expiration dates listed on driver-side B-pillar. Upon expiration (15 years), components must be replaced. Air bag modules must not be stored for longer than 3 months.
• DO NOT use air bag system components dropped from heights of approximately 20" (0.5 m) or higher. Always replace air bag components mechanically damaged.
• Disable air bag system before servicing any part of system. See DISABLING & ACTIVATING AIR BAG SYSTEM  .
• Before disconnecting battery cable(s) and disabling air bag system, obtain radio security code from vehicle owner.
• After servicing, check system for proper operation. See SYSTEM OPERATION CHECK in appropriate AIR BAG RESTRAINT SYSTEMS article.
• DO NOT leave undeployed air bag system components unattended. Install components in vehicle immediately after removing from packaging.
• When placing undeployed air bag modules on a bench or other surface, always make certain trim cover faces up.
• DO NOT allow chemical cleaners, oil, or grease to contact vinyl covering on air bag modules.
• DO NOT expose air bag modules to temperatures greater than 212°F (100°C).
• Use only original equipment seat covers designed for use with side air bags (identified by label on fabric).
