If this happens, gently pull on the end of the wire harness at the top of the upright tube assembly (A) to clear the hole. Do not force the bolt through the hole if the wire harness is obstructing the bolt, as damage to the wire harness may result.

#2 and #3 apply to model X5i only. To avoid stripping, do not over tighten screws.
Threads are formed in the holes as the screw goes in. A power screw-driver is recommended if available.
