I am thankful for this little warning light that appears on the dashboard of my Escape from time to time. It's a low tire pressure warning. It popped on as I was driving into town this morning, alerting me to the need to head to the nearest tire store for an inspection. It turned out that my right front tire was low and needing air. They had just been checked when I had the oil changed this week, so apparently the tech misread the gauge or the overnight drop to below freezing temperatures affected it. Twice in the past this light has warned me of a nail in a tire which could have easily left me stranded out on the road somewhere with a flat. I readily admit that I am not the most observant person in the world, so I am very thankful for helpful gadgets like this!
