    Adjust the clearance between the roof panel reinforcement bracket and roof panel reinforcement plate.


    1. Temporarily place the roof panel on the vehicle and fix the front and back in place using locking pliers.

    2. Make sure that A (welded area) of the roof panel and roof panel reinforcement bracket do not interfere with the vehicle.

    3. Visually make sure there is a clearance between the roof panel reinforcement bracket and roof panel reinforcement plate.

    4. Visually make sure the clearance between the roof panel reinforcement bracket and roof panel reinforcement plate is parallel.

      Tech Tips

      If the clearance is not parallel with the roof panel reinforcement plate, lightly tap the roof panel reinforcement plate until it is parallel.

    5. Measure the clearance labeled *a, and choose shims according to the chart.

      Tech Tips

      There are two types of shims: 0.5 mm and 1.0 mm

      Clearance Shim
      0.5 mm (0.020 in.) or less -
      0.6 to 1.0 mm (0.024 to 0.039 in.) 0.5 mm (0.020 in.)
      1.1 to 1.5 mm (0.043 to 0.059 in.) 1.0 mm (0.024 in.)
      1.6 to 2.0 mm (0.063 to 0.079 in.) 0.5 + 1.0 mm (0.020 + 0.024 in.)
      2.1 to 2.5 mm (0.083 to 0.098 in.) 1.0 + 1.0 mm (0.024 + 0.024 in.)
      2.6 to 3.0 mm (0.102 to 0.118 in.) 0.5 + 1.0 + 1.0 mm (0.020 + 0.024 + 0.024 in.)
      3.1 to 3.5 mm (0.122 to 0.138 in.) 1.0 + 1.0 + 1.0 mm (0.024 + 0.024 + 0.024 in.)

  • Place shims in the clearance between the roof panel and roof panel reinforcement plate and tighten the bolts.

    Tech Tips

    Be sure to tighten the bolts in diametric order.

  • A01FK4RC01
    *a Thickness Gauge

    After tightening all the bolts, check the contact points between the roof panel and roof side outer upper rail with a thickness gauge.

    Tech Tips


    • If there is a difference between the left and right sides, confirm the roof panel installation and perform adjustment when necessary.

    • Change to a thinner shim if the roof panel changes when it is lightly pushed.

  • Remove the paint film where the adhesive will be applied for the roof panel and roof side outer upper No.1 rail.

    Tech Tips

    Do not remove the paint film where the roof drip moulding sub-assembly is installed.


    1. Install the roof drip moulding sub-assembly.
