Manual Adjustable Steering Column
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The manual adjustable steering column is controlled by a mechanical lever on the underside of the steering column, which uses a cam to lock and unlock the steering column. The steering column can be adjusted when the lever is pulled downward. When the steering column is in the desired position(s), pulling the lever upward to its original position locks the steering column.
