Tell tim to look at his right knee, just above it should be 2 buttons and a dial on a flat section just above the cubby hole (if he doesnt hace cruise control, he might only have 1 button). If he does have TC, it will be the button on the right labelled ESP. Hit that, and the light on the dash should come on as a warning that you have turned it off.
Its been a long day, this might all be w**k
