When I flick the key (or touch the battery icon on the screen) to switch to "Performance" mode, it often displays "Performance" in red letters and then, 3-5 seconds later, switches over to "Performance" in white letters. Sometimes, it never switches over to white letters...and stays with red "Performance" lettering (this morning it did this - 20 minutes of driving...never switched over to the white lettering). Does the red lettering mean I'm NOT in Performance mode? And, if this is the case...why? I get no error messages, I'm not doing anything funky. Temps all look good, battery level is over 80% but below 90%.
