The Engine Light signifies that there is an issue with the engine system, such as an overheated engine or a malfunctioning sensor. The Oil Light indicates that the oil level in the engine is low and needs to be replenished. The Battery Light indicates that the battery is not being charged properly and needs to be checked. If any of these lights are on, it is important to take your car to a mechanic as soon as possible in order to diagnose and fix the issue.
