what does row of red lights flashing and beeping on dashboard mean?

Hello, You will really need to identify which lights were lighting up, and the best way to do that is to turn the key on, but don't start the engine. The warning lights should come on, and you can compare those to the warning light symbols in the owner's manual. It is concerning, I know, but if the vehicle is not having driveability symptoms when this happens, it may just be isolated to a defective instrument cluster or body control module.
