That is what Honda recommeds. I think mileage is a more important indicator then aqe unless you are living in an area with extremes in temperatures, then age can also become a factor. The big problem is you can not inspect the conditon of the belt unless you tear apart the front part of the engine. You can stretch the numbers a bit but failure to change the belts can be very expensive if it breaks .(A broken belt bends valves and requires a valve job to fix.)
