    • Do not expose the inflator modules to temperatures above 65°C (150°F).
    • Verify the correct replacement part number. Do not substitute a component from a different vehicle.
    • Do not repair any of the following components. Service these components by replacement only:
       - The inflatable restraint sensing and diagnostic module (SDM)
       - The inflatable restraint I/P module
       - The inflatable restraint steering wheel module
       - The inflatable restraint steering wheel module coil
       - The inflatable restraint side impact sensors (SIS)
       - The inflatable restraint side impact modules
       - The seat belt pretensioners
    • Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system.
    • Discard any of the following components if the component has been dropped from a height of 91 centimeters (3  feet) or greater.
       - The inflatable restraint sensing and diagnostic module (SDM)
       - The inflatable restraint IP module
       - The inflatable restraint steering wheel module
       - The inflatable restraint steering wheel module coil
       - The inflatable restraint side impact sensors (SIS)
       - The inflatable restraint side impact modules
       - The seat belt pretensioners
    • When you replace the SDM, verify that the following conditions are met:
       - The mounting surface is clean.
       - The arrow on the module points toward the front of the vehicle.
       - The SDM is flat on the mounting surface, parallel to the vehicle datum line.
       - The SDM fasteners are installed and tightened as specified.
    • When you replace an inflatable restraint side impact sensor (SIS), verify that the following conditions are met:
       - The mounting surface is clean.
       - The SIS is flat on the mounting surface.
       - The SIS fasteners are installed and tightened as specified.
    • In order to avoid setting false diagnostic trouble codes, only apply power to the SIR system when one of the following two conditions is met:
       - All SIR system components are properly mounted and electrically connected.
       - A diagnostic procedure directs you to apply power.
