CAUTION
If any of the wall rivnuts spin while applying torque to the bolt, try to tighten in place with a nutsert tool. If
unable to tighten in place, remove the upper anchor rail and replace the defective rivnut(s). Refer to your
parts manual for the proper rivnuts to use.

PROCEDURE
LEVEL 1:
1.1- INSPECT THE SEATS’ UPPER ANCHOR RAILS AND THE HARDWARE THAT AFFIXES
THE SEATS TO THE UPPER ANCHOR RAILS.
1.1. Visually inspect all the upper anchor rails located between the front wheelhouses and the rear of the vehicle
for any cracks and/or deformities. See Figure 1.
a. If any cracks and/or deformities are visible on the top anchor rails, go to step 2.1. If no defect are found
after inspection, proceed with the next step of the level 1 procedure.
WARNING
FOLLOW YOUR INTERNAL SAFETY PROCEDURES.
Inspect all the rails inside the dashed rectangles.

SEATS WITH NO STANCHION AFFIXED TO THE BACKREST
NOTE
When removing any passenger seat and/or seat belts from the anchor rail, all T-bolts and nuts should be
discarded and snever be reused to affix a passenger seat or seat belt.
