If the side curtain airbag has not deployed, to prevent the side curtain airbags from deploying improperly and possibly causing injury, inspect removed pieces and replace them if they have any of these types of damage:
Any cracks or damages in the grab handle (A).
Any cracks or stress-whitenings in the caps (B).
Install the clips (A) to the grab handle (B), then install the caps (C) fully into the clips.
Position the grab handle (A) on the bracket (B), and push on the grab handle until the clips (C) snap into place securely.
