This should be so simple. TPMS calibration.

Have spent over a half hour with internet searches trying to reset the TPMS warning on my 2018 Clarity. It MUST be buried somewhere in the menus, but cannot be unearthed by me.

Thanks so much. Now I finally know the location of my Owner's Manual!

You may just have the 160 page Owner's Guide as that is what comes with the car. The full Owner's Manual (nearly 600 pages) can be downloaded from the Honda website. Although not quite as easy to read cover-to-cover it does have a lot more detail about specific topics.

Being able to search the .PDF file for contents really saves time, and doesn't fill up your glove compartment.

Definitely, plus I use the search function all the time, it's called Find on Page in my PDF reader. Although you have to think through what search terms to use, searching just the word "battery" by itself for example has like 500 results.
