Step-by-step explanation:
When you start your car, there are three lights on the dashboard that you need to make sure come on and then turn off. These lights are the check engine light, the oil pressure light, and the battery light.
The check engine light comes on when there is a problem with the engine or emissions system. It should turn off after a few seconds. The oil pressure light indicates that there is low oil pressure, which can be caused by a variety of issues. It should also turn off after a few seconds. The battery light comes on when there is a problem with the car's charging system. It should turn off once the engine is running and the alternator is charging the battery.
