Trying to turn my steering wheel and lane assist off, I hold down the lka button and it goes into orange/brown for lane keep assist, but it says to just tap the same button for 3 seconds to turn steering wheel assist off, most I get is a grey steering icon, but assist still seems to be on, and the auto correct nightmare, pulls me into ditches along the side of the road. Is this steering wheel icon supposed to be grey to turn it off or is it supposed to be brown like lka?
