This is the message on the dash of my parent's 2018 Rav4, non-hybrid with 14k miles. How can I find out what the maintenance is? On my CR-V, the maintenance message comes with codes that you can reference to the owner's manual to figure out exactly what the maintenance is. The Rav4 owner's manual says to refer to the maintenance guide but the maintenance guide is pretty generic. Bottom line, just trying to figure out what maintenance is required.
