I recently acquired the Transformers game Revenge of the Fallen. But so far, one part of the game has eluded me: How do you steer in vehicle mode? I get a square blue targeting reticle that slides over to the left of the screen and stays there. I don't appear to have any control over left and right steering or direction to aim the vehicle. What functions control vehicle mode? And please don't use the key names, because I have a custom control setup. And what are the strange arrow symbols in this picture?
