That's a New One

I tend to get unreasonably stressed by automobile warning lights. When this came on I couldn't imagine what I was supposed to think about it. Avoid going downhill? Warning - you are actually going downhill even though your senses inform you the road is flat? 

I was also unreasonably impressed that I figured it out on my own. It wasn't even a warning! It was simply providing a reminder I had pressed that innocuous button on the gearshift I never really took any notice of before. 

The only red indicator light I really want is the one that informs me to immediately exit the car and run away as fast of possible before it blows up. That  one I would understand.
