One night this week I noticed that the instrument panel was brighter than usual, and I couldn't remember how to adjust it. Assuming it would be via a screen like everything else, I scrolled through the menus for both screens without success, so I resorted to the manual. This reminded me that there is a prominent old-fashioned twiddleable knob to the upper right of the speedometer. If only all the adjustments were so easy! My feeble excuse is that it was dark when the problem arose......
