A930Rocket,
I have no idea. I have had the car about 5 days and have not spent a lot of time with it yet. Trying to work out the basics. I'm hoping it's the "oil slick" knob I would really like that for the big diesel pick-up trucks that like to tailgate 1.5 ton cars...

'Course when I get this thing running I am hoping that issue can be easily alleviated with the pedal on the right.
