Annoying “Oil Maintenance Reqd” screen...warning or nuisance?

Press and hold the OdO Reset button, and press the “Start” twice without touching the brake pedal. Continue to hold down the Trip Odometer Reset button until “000000” MILES appears on the display and the maintenance light turns off.

I put electrical tape over the tpms light when the tpms sensors die.

The brake caliper pins freeze and need yearly maintenance.

Welcome

 

Synthetic oil is good for 10k miles but the reminder comes up every 5000 for your rotations and such. This is covered in the owner's manual.

To reset I believe it's

1. Set your odometer to show trip A, then turn off car.
2. While pressing the button that changes miles/kilometers, start car and watch the odometer reading reset.

 

Most gen 3 likely have those warning, my 2013 just say "maintenance required", there's a 3 step cancel in the manual somewhere, some will chime in on that.
I personally do not heed that warning, used to go 10k per oil change though read a post here they go 7-8k, I would check the dipstick oil level and quality (color, smell, feel) occasionally when and if I remember it...

I bet that the word "oil" is NOT in the displayed message.......and it is indicating that you are due for their recommended 5K mile tire rotation.

If you don't have an owners manual, you might want to get one.
If you have one already.......you might want to read it.

 

it is just a reminder. reset it and move on. no worries, change your oil a filter every 10k with mobil 1.

how many miles on her? at some point, you'll want to clean the egr circuit and intake manifold to try and prevent oil burning and a blown head gasket.
maybe install an oil catch can.

 

When the 2010 Prius was released (I ordered one just a month later), the oil change interval was 5000 miles. Only many months later did Toyota officially and retroactively boost it to 10,000 miles. But there was no reprogramming to change the reminder display, so my 2012 still pops up with the reminder at the same 5k interval.

The maintenance schedule still calls for (very minimal) service at 5k intervals: tire rotation. I just to my tire rotation with my winter season tire swaps, decoupled from actual miles. This way it takes zero extra time and labor.

 

It's just a suggestion. You can change the oil, or not. I mean the worst thing can happen is the beginning of oil consumption, blown head gasket, low oil pressure and engine seizing. It's not new here, it happens all the time on priuschat so it's not a big deal.

 

It's a simple reminder that goes off every 5,000 miles since it was last reset. It doesn't know when you changed the oil, what oil you used or whether you drove under harsh conditions. The reason being, Toyota specifies a maintenance check every 5,000 miles in their maintenance schedule. If you last filled with 0W-20, you don't have to change again for 10,000 miles. Anything else, and you're supposed to change at 5,000 mile intervals. Toyota does not specify "synthetic" oil anywhere in the service recommendations. The only specification is for the viscosity.

 

Just learn how to turn it off, and stick to some maintenance schedule, independent of it.

Canadian Prius, we don't have it, heehee.
