So what’s this icon mean

[Viper67]

Today was the first time I towed. What is this that I circled in red? Can’t figure out what 417 means. And it nailed the length of my trailer.

It's the highest allowed or that can be recorded by the water sensor...you're water temp was 210 which is great.... if you ever see anything even near 417, well, run!
