I know when the cruise is engaged... I take my foot off and the car keeps going.
Heck, I think they should make all the control markings in BRAILLE, because I can't see any of them. And the cruise "engaged" LED light is least important. But after about 7500 miles, I kinda got a feel for where everything is at.
Now if I could just quit turning on the wipers when I press the cruise button.
