Looks like yours has the same slide-out for the bed as my Forester. If you have two grey metal rails on each side, then its the Schwintek model. There are You Tube videos on the manual override and retiming. Here is the over-ride.
There are also a few videos on the manual over ride and more on the FR video website.
