Checking and Adjusting the Headliner/Pillar Trim Overlap

To prevent the side curtain airbag from deploying and damaging the pillar trim, the overlap between the headliner and pillar trim must be less than 8 mm (0.31 in). To check the overlap, do this:

1. Install the headliner (A) and the pillar trim (B).

3. Remove the pillar trim, and measure the headliner overlap.
   • If the overlap is less than 8 mm (0.31 in), remove the tape, and install the pillar trim.
   • If the overlap is more than 8 mm (0.31 in), go to step  4.
