I doubt its possible to adjust the problem, but I was wondering the same thing. Something else I am curious about is what 'state' that button has to be in for LDW and FCW to be activated. All the other buttons in that area of the car show no amber light. But the LDW/FCW button shows a yellow/amber light. Does that mean its on? ( I am pretty sure it does) Odd that it requires a light to show that its on, and the other buttons just use the dash to tell you if you have turned them off. This being a brand new car, and me having no prior experience, makes it a little unnerving knowing if I have all the safety features activated or not. I tried to read the little pamphlet that came with the technology package, but it said nothing about the 'state of the button' to know if its on or off.
Any help is appreciated.
