How to reset the maintenance required light on a 2004-2009 Toyota Prius

maintenance required light on Toyota Prius combination meter

This falls under the “really old news category”, but I’m writing it for a reason. I just had a customer call in to schedule a 5K service because her maint req light was on. When I checked her file, we had just done a service about 2,000 miles ago. Oops! I know, it’s lame. Anyway, she was game to reset the light on her own, so I said I’d send some instructions.

My original intention was to cut and paste some instructions from the internet because, you know, why recreate something that already exists. Anybody familiar with tech support is also likely familiar with Google and cutting and pasting.

The thing is, I didn’t really like any of the instructions I found. There were lots of places where the reader could get confused and do the wrong thing. So, I decided to write my own instructions. It may turn out that my instructions are every bit as poorly written as the instructions I found in the Google featured snippet. I am subject to editing blindness on occasion. When I proofread I read what I was thinking, not what I actually wrote. I’ll let you be the judge.
