Your car’s dashboard is like its communication center, alerting you when something needs your attention. But with so many different icons and lights, it’s not always easy to know what they mean—or how serious they are. Some lights signal minor issues, while others warn you to pull over immediately.
Knowing these key dashboard warning lights can help you react appropriately and avoid bigger problems down the road.
1. Check Engine Light
The check engine light is one of the most common alerts, but it can mean many things. It might indicate a loose gas cap, a failing sensor, or something more serious like a misfire or catalytic converter issue. A solid light usually suggests a non-urgent problem, while a flashing light calls for immediate attention.
2. Oil Pressure Warning
This light looks like an old-fashioned oil can and signals low oil pressure. Without proper oil pressure, your engine could suffer severe damage quickly. If this light comes on while driving, it’s best to pull over and turn off the engine as soon as possible.
3. Battery/Charging System Warning
If you see a battery symbol, your vehicle may not be charging properly. It could be a failing alternator, battery, or another electrical problem. Ignoring this warning could leave you stranded once your battery runs out of power.
4. Brake System Warning
A red brake warning light can indicate several things: low brake fluid, worn brake pads, or an issue with the braking system itself. If it stays on after releasing the parking brake, it’s smart to have your brakes inspected right away.
5. Tire Pressure Monitoring System (TPMS) Light
This light typically looks like a horseshoe with an exclamation mark inside. It alerts you that one or more of your tires are significantly underinflated, which can affect handling, tire life, and fuel economy. Check your tire pressure as soon as you can.
6. Coolant Temperature Warning
If your temperature gauge spikes or you see a thermometer symbol, your engine may be overheating. Continuing to drive could cause serious damage. It's important to pull over safely, turn off the engine, and allow it to cool before checking coolant levels.
7. ABS Warning Light
The Anti-lock Braking System (ABS) helps you maintain steering control during emergency stops. If this light comes on, it doesn’t mean your brakes are gone—it just means the ABS function might not be working properly. You should still have it checked to ensure full braking capability.
8. Airbag Warning Light
When the airbag warning light stays on, it means there could be a fault in the airbag system. This could prevent the airbags from deploying in a crash, so it’s important to have the system diagnosed and repaired as soon as possible.
9. Traction Control Warning
This light often flashes when your traction control system is actively keeping your wheels from slipping. If it stays illuminated, it might mean there’s an issue with a wheel sensor or the traction control system itself.
10. Service Vehicle Soon Light
Sometimes confused with the check engine light, this light usually indicates that your vehicle is due for regular maintenance. It might remind you to change your oil, check your brakes, or service the transmission depending on the manufacturer’s schedule.
