An icon in the instrument cluster that looks like a warning comes on when i start the car. the icon is a red triangle with an exclamation point in the middle. there is also a smaller orange icon that of the same type that stays on constantly (the triangle with a an exclamation point.

This is supposed to be the master warning light indicating that a message is being shown in the information display in the instrument panel. Look at this screen to see what the specific problem is. https://www.toyota.com/t3Portal/document/om-s/OM33748U/pdf/OM33748U.pdf

If it's an exclamation point inside a triangle, it's called a master warning symbol. This is the Master Warning Light symbol. If this light is on, there will likely be text displayed as well on the instrument panel, or another warning light. Look for text in particular. It could very well point out something as serious as low oil pressure. If the engine is not running, you can't very well check your gauges, but you may have lost all oil pressure or overheated the engine. Recommend you consult a mechanic familiar with your model.

I really hope helps with this (remember rated this help) Good luck.

Sounds like the instrument cluster has gone bad or a bulb in the cluster has burnt out. You will need to remove the cluster and check the bulbs to see if they need to be replaced.

Pull up the error codes.
