The MAINT REQD indicator flashed today when I reached 4501 miles. According to the Owner's Manual, this is expected to occur 4500 miles (7200 km) after engine oil replacement. The only problem is that I had my oil changed at 1500 miles (upon dealer recommendation... said Toyota uses "starter" oil... ok, whatever. It was free anyway). Therefore, the indicator should have flashed at 6000 miles. I proceeded to read in the manual that "the system must be reset after the engine oil replacement" and it follows with specific directions on how to reset it. I guess the service department did not reset the system. The problem I have with this procedure is that the odometer will be reset to 0 (according to the owner's manual). Am I understanding this correctly? How will I know the lifetime mileage of my vehicle? Also, the manual says that at 5000 miles after the engine oil replacement, the indicator will remain lit. I suppose it will not turn out until after a system reset? Therefore, if I have another oil change at 6500 miles as scheduled, and they forget to reset the system, I should expect this indicator to continue to remain lit?
