Hi, just wondered, on my 2015 eco, where I switch my lights on, is the 2 fog light button, for front and rear fogs. The front fog button, also if turned acts as a headlight adjuster. Rear fog button, also acts as a dimmer, so if turned dims your dash lights. I not tried it, just thought of it, may be that may dim the display? May not, just worth a try. It more likely done via the screen.
