Removal Procedure

    Object Number: 513377 Size: SH

    Caution: When you are carrying an undeployed inflator module:

       • Do not carry the inflator module by the wires or connector on the inflator module
       • Make sure the bag opening points away from you
    When you are storing an undeployed inflator module, make sure the bag opening points away from the surface on which the inflator module rests. When you are storing a steering column, do not rest the column with the bag opening facing down and the column vertical. Provide free space for the air bag to expand in case of an accidental deployment. Otherwise, personal injury may result.

    Caution: Following the deployment of a side impact air bag, inspect the following parts for damage. Replace these parts if necessary:

       • The seat cushion frame
       • The seat recliner, if equipped
       • The seat adjuster
       • The seat back frame
    Failure to do so may cause future personal injury.
