Common Car Warning Lights
Car warning lights tell you if something needs attention. They help keep your car safe and working well.
Knowing what each light means can save you time and money. Here are some common warning lights you might see.
Engine Warning Light
The engine warning light shows a problem with your engine or emissions system. It can be yellow or orange and looks like an engine shape.
If this light comes on, your car needs a checkup soon. Driving with this light on may cause damage or reduce fuel efficiency.
Battery Alert
The battery alert light looks like a battery icon. It means your car’s charging system is not working properly.
This light may come on if the alternator or battery has a problem. Your car might stop running if the battery dies.
Oil Pressure Indicator
The oil pressure light looks like an oil can. It warns that the oil pressure is too low in the engine.
Low oil pressure can cause serious engine damage. Stop the car and check the oil level right away if this light turns on.
Brake System Warning
The brake warning light usually looks like an exclamation mark inside a circle or the word “BRAKE.” It signals a problem with your brake system.
This light can mean low brake fluid, worn brake pads, or a brake system fault. Check your brakes immediately for safety.

The tire pressure monitor light looks like an exclamation mark inside a horseshoe shape. It shows one or more tires have low pressure.
Low tire pressure can cause poor handling and increase tire wear. Check your tire pressure and inflate tires as needed.
