The following steps are shown on the left side of the vehicle and must be accomplished analogously on the right side in the event of damage.

1. Scribe separating point and cut (areas A₁ , A₂ , A₃ , B₁ and B2).

   Separating points in areas A₁ , A₂ , A₃ , B₁ and B₂ facilitate removal. Measure dimension (a) from reference line.

2. Remove sections (8.1) and (8.2).
3. Expose spot weld on roof paneling section (7) and cut out (area C).
4. Scribe separating point on roof paneling section (7) and cut (area B₃ ).

   Do not cut too deeply.

   Otherwise the components below can be damaged and weakened.

   Roof paneling section (7) is required for installation. Measure dimensions (b₁ and b₂ ) from reference lines.

5. Remove roof paneling section (7).
6. Scribe separating point on A and B-pillar paneling (1) and cut (area D₃ ).

   Do not cut too deeply.

   Otherwise the components below can be damaged and weakened.

   Measure dimensions (b₃ and b₄ ) from hole (arrow).

7. Expose spot welds on A and B-pillar paneling (1) and cut out (areas D₁ and D₂ ).
8. Remove section on A and B-pillar paneling (1).
9. Expose spot welds on side wall reinforcement (2) and cut out (areas Ei and E3).
10. Drill out spot welds on side wall reinforcement (2) (area E₂ ).
11. Heat side wall reinforcement (2) in crosshatched area.

    Cross-hatched area is bonded.

12. Remove side wall reinforcement section (2).

15. Scribe separating point on A and B-pillar paneling (1) and cut (area I).

    Do not cut too deeply.

    Otherwise the components below can be damaged and weakened.

    Measure dimension (c) from reference line.

16. Expose spot welds on A and B-pillar paneling (1) and cut out (areas G₁ , G₂ , G₃ , G₄ , H₁ and H₂ ).

    Cut out spot welds through two panel thicknesses (areas G₁ and G₄ ).

17. Remove damaged A and B-pillar paneling (1).

18. Scribe separating point on side wall reinforcement (2) and cut (area K₂ ).

    Do not cut too deeply.

    Otherwise the components below can be damaged and weakened.

    Measure dimension (d) from reference line.

19. Expose MIG solder seam on side wall reinforcement (2) and grind off (area K,).
20. Expose spot welds on side wall reinforcement (2) and cut out (areas J₁ , J₂ , J₃ and J₄ ).

    Cut out weld spots through two panel thicknesses (area J₃ ).

21. Heat side wall reinforcement (2) in crosshatched area.

    Cross-hatched area is bonded.

22. Remove damaged side wall reinforcement (2).
23. Expose spot welds on inner front side wall (3) and cut out (areas L₁ , L₂ , L₃ and L₄ ).
24. Remove damaged inner front side wall (3).

25. Grind mating surfaces down to bare metal in the cross-hatched inner C-pillar side wall.

    Sand down spot weld flanges to bare metal on both sides.

26. Remove shavings and drill chips.
27. Coat insides of spot weld flanges with zinc dust paint.
