Default master Hybrid Warning Light

Master warning light came on for first time. I just went over 100,000 miles. had car oil changed, and shampood. Now light is on. Help!!
Any chance it can be the extra humidity build up since the shampoo? just few days ago, and it did get real humid in the car yesterday with windows closed.??
Can't find the manual.

Just a guess, but check your ICE (Internal Combustion Engine) oil level. If it is overfilled, it is possible that your Prius sucked oil into the manifold, stumbled when attempting to start, and threw a "failed to start" code, after which your car won't even attempt to start. This is also more common in subfreezing weather, so if your area had a recent cold-snap, this is a possibility.

Simple fix, if the oil is overfilled, drain enough oil to get the level down to where it is supposed to be. Disconnect the 12-volt battery for a couple of minutes to reset the codes. Then, attempt to start car. If that was it, it should start OK.

If not, please provide fail codes so others can help troubleshoot your problem.

Thanks

Note: This was a common occurrence in older Prius's, and it happened years ago on our 2002. The oil capacity is 3.7 quarts in a 2002, and most oil change places will add 4 quarts during an oil change. We have even had our Toyota dealer do this numerous times, most recently a month ago. Since you mentioned that you had an oil change, if it's overfilled, take it back and let them drain the excess.
