You will feel a reduction in available power, the display will indicate words to the effect "reduced engine power", and I can't recall exactly, but I think that stays on until you shut the engine down. It can be safely driven (assuming you are not needing all available power) to your destination or a place where you can park and turn the car off. If you are not expecting it and/or know what caused it, it can be somewhat disconcerting. When this happens, there will generally, perhaps always, be stored in the auto computer one or more codes that explain the reason for the reduced power. For some (most?) codes, the codes can be erased with the proper scanning tool. For example, when mine went into limp mode, the codes were 4C7C and 0467.

This is not the same thing as the Check Engine or Service Required lights.

Other fellows may need to correct some of my terminology as I am doing this strictly from memory.
