FSS Question

[ml28]

My FSS is showing a wrench symbol along with "30 d" which I know means 30 days until I need to change the oil. It was showing miles until recently. My question to you all is does the FSS automatically switch from miles left to days left or did I inadvertantly do something that caused it to display days instead of miles. I would prefer to see miles left instead of days. I bought the vehicle used and was not fortunate enough to get an owner's manual with it. I've also used the search function on the forum and was not able to find the answer. Any help would truly be appreciated.

Thanks!

That's a normal thing for the fss to do. It has realised that you won't do the remaining milage before the set remaining time so it has switched to displaying remaining time.

When you reset the fss it resets both time and milage. It will display milage unless the time counter becomes more important to your service interval.
