I have an SR5. You can clearly see that a lever and a knob should be there. I ordered both from the dealer. But, I am just wondering...IF they are suppose to be there, why is there no hole in the leather. Clearly, the leather has not been replaced cause it is slightly worn from use. Also, even if the leather had been replaced, wouldn't you think the knobs would have been put back? I am going to talk to the service department when I pick up the knobs and see if they think this was a mistake from the factory. IF my seats didn't have adjustment options, then why would the hardware be there and almost poking through the leather? It doesn't make any sense. I did move the leather and adjusted the seat with pliers to get it right, so I know it can be adjusted.
