I actually tried the settings in my FR-S instead of just pontificating about what might be (not that I don't enjoy doing this from time to time, but not this time). Here's what I found:

After setting the rev indicator light I discovered there is a tach sweep on the FR-S. On startup after setting the rev indicator light (I also set the buzzer, but I don't think that changed things), it doesn't randomly sweep the tach. It sweeps the tach needle to the set warning RPM and lights up the indicator to let you know were it is set as you start the car. If you decide not to use the rev light indicator warning, I think that the tach will not sweep in the FR-S. I know my tach did not sweep on startup before setting the rev indicator light. I don't think it is possible to set this independently like it is in the BRZ.

Oh, and thanks for the thread kablammo. I didn't even know the settings existed in the manual FR-S before this post. [not big on pouring over the manual]

I am not surprised.

There are many, unfortunately, who have never learned the discipline of reading. That is why they have become lazy and ask stupid questions on the internet that they could have easily learned by reading the Owner's Manual --- or --- they have read the Manual but cannot comprehend the instructions. They should also socialize more and find a friend to help them out on some issues that come up. Being anonymous, on the internet, allows one to ask these stupid questions without being embarrassed.

This is not always the case as there are some very valid questions that are brought up.

To be fair, I myself had to refer to the manual yesterday. I read the whole thing, but didn't memorize it(it was late spring at the time). My window was frozen shut and the button lights were blinking as soon as got in the car. First time that's happened. After reading the manual(which I still keep in the car), I went through the steps and the fix wouldn't work. The manual says "with the car stopped, and the ignition in the ON position..."

What they should have said was with the ENGINE stopped and the ignition in the ON position. Because when I shut off the engine and tried again, the fix worked. By the way, you have to roll the window all the way down first. Then the auto function works and the blinking stops. Hope this helps.

By the way, I love reading manuals. But my memory ain't what it used to be.

Me too. :cheers:
