Red Triangle and beep for 1 second or less

I had the same thing with the red triangle coming on for a few seconds but I didn't have the oil light. The red triangle came on for a few seconds only on tight turns at higher speeds on the highway. It had been about 5k since last oil change and the red triangle was coming on for about 2k miles before I found out it was oil while on vacation. The oil was below the dipstick so I put 2 quarts in to get it halfway between the dots and drove it another 500 miles before I did the oil change. It has 162k miles on it and is an 06. I will start checking the oil now.

 

Thank God I googled this issue and found this thread! I bought my 2005 Prius about 18 months ago and it didn't come with a manual so I'm working blind. I have had the oil changed and I don't drive it much, but I guess short trips must be harder on it than I realized. My oil was 2 qts low...thank God I caught it fast.
I don't think it's been even 3000 miles since my last oil change (the car is around 155,000)... what would cause it to burn oil so fast (no sign of any leaking).

 

You can download a copy of the owners manual online. If you search around Priuschat you will notice the oil burning is a very common issue. It’s due to a bad design of the pistons and rings.
