    The Triangle is the master warning light. You should take it to a Toyota Dealership and get the vehcle hooked to the diagnostic computer. Without the results of the scan, we cannot tell you why the light is on.

The triangle with an exclaimation mark in the middle is the Master Warning Light . I havn't had time to check out exactly what it is but is is covered in the service reminders part of the owners manual. Google " 2005 prius warning lights . In the first result , you will find a link to toyotapartsandservice.com where you will find owners manual's etc. ( in english )

Prius 2005 triangle indication


The Triangle indication:
Description: MASTER WARNING LIGHT.
The battery ECU has a self-diagnosis system. If the computer, High Voltage (HV) battery system or the components are not working properly, the ECU carries out a diagnosis to detect the malfunction, and illuminates the master warning light in the combination meter together with the HV system warning indicator on the multi information display.
NOTE:
The master warning light illuminates when the HV battery system fails and it blinks when in inspection mode.

What does it mean warning light TRIANGLE WITH SNOW on TOYOTA PRIUS 20 dashboard


Hello,
There is absolutely nothing wrong with your car. It's actually keeping you safe! If the outside ambient temperature is +37F or lower, your car knows this and gives a warning for possible black ice conditions. Lots of people wonder the same thing, next time it shows the warning, note the outside temp to see if it's below +37F.

I hope this info helps!

A warning light appear with my hibrid prius


I have same engine problem. Triangle signal pop up after I try to start my Prius with a still wet air filter to the car . The engine just run for less than 30 sec. and stopped with the triangle signe pop up. I think this sign will pop up whenever the engine detect certain major function failure. For my case, it was due to retricted air supply to the engine. I have tried Lovebytes suggestion and the triangle sign disappeared with a dry clean filter. My Prius is running good now. This warnig sign may have other implications. Once you try this method and sign still come on. You need to have your car check by garage.
Bellow attach is the answer from Lovebites

What does it mean when a waning sign comes up with a picture of a car & an explaination mark? and also a triangle with an explaination mark, both at the same time??


The Prius has electric power steering. The "PS" in a rectangle means that the computer has detected a problem there. The red triangle with an explanation mark means that the computer has detected a problem with the Hybrid System. Usually it is accompanied by red symbol of an automobile. In any case you should take the car to a dealer who can read the diagnostic codes from the computer and determine the cause of the problem.

Prius series 1 (1998) warning sign


You will need to have this light reset with a scan tool, it is stored in a non-volatile (stays in memory with or without battery voltage) memory. Have the dealer check the cause, better than a tow bill.

2003 Prius Hybrid System Warning Light


My Toyota Prius hybrid warning light has come on three times in eight years. If I turn the car off for 20 minutes, the hybrid light is off but the check engine light is on. After a while, the check engine light goes off. I think this problem is related to moisture somehow entering the hybrid vent on the driver's side. All three times this has happened, the weather was wet. Kevin Cardiff
