Common Warning Lights on Your Car’s Dashboard

1. Check Engine Light (CEL)

The check engine light is one of the most common warning symbols drivers encounter. If you see a yellow or orange engine symbol, it means your car’s onboard diagnostics have detected an issue. This could range from something as simple as a loose gas cap to a more serious engine problem, like a misfire or a failing catalytic converter.

At Trustworthy Auto, we specialize in check engine light diagnostics. Our team uses advanced tools to connect to your car’s computer and retrieve the trouble codes. From there, we’ll pinpoint the exact issue and advise you on the necessary repairs.

2. Traction Control Light

When the traction control light comes on, it means your car’s traction control system has been activated. This is usually triggered when your vehicle detects slippery or uneven surfaces, helping to prevent you from losing control. However, if the traction control light stays on continuously, it could indicate a malfunction in the system. We often handle dashboard diagnostics and testing to ensure that your traction control system is functioning properly.

3. Brake Warning Light

The brake light is usually red and should never be ignored. If it’s illuminated, it could mean a number of things, such as:

We perform thorough brake inspections at Trustworthy Auto and always recommend addressing brake issues promptly for your safety. If the brake light remains on, it’s time to bring your car in for diagnostics.

4. Tire Pressure Warning Light (Exclamation Point on My Dashboard)

The Tire Pressure Warning Light looks like an exclamation point inside a horseshoe and indicates that one or more of your tires may be under-inflated or over-inflated. Keeping your tires at the correct pressure is critical for safety, fuel efficiency, and tire longevity. If this light appears, check your tire pressure as soon as possible, and if you’re unsure, visit Trustworthy Auto in Seekonk, MA, for assistance.

5. Battery Light

The battery warning light typically indicates an issue with your car’s charging system. It could mean your battery is not charging properly, or there’s a problem with the alternator. If this light comes on, you should have your vehicle checked immediately, as you could end up stranded with a dead battery.

At Trustworthy Auto, we can test your battery and charging system to determine if you need a new battery or further repairs to your vehicle’s electrical system.

6. Oil Pressure Light

If you see an oil can symbol on your dashboard, it’s a sign that your oil pressure is too low. This could be due to low oil levels or a more serious issue, like an oil pump failure. Either way, driving with this light on can severely damage your engine. We recommend pulling over and checking your oil level right away, and if it’s low, don’t continue driving without addressing the issue.

7. Coolant Temperature Light

The coolant temperature light (often displayed as a thermometer symbol) indicates that your engine is overheating. This can happen for various reasons, such as low coolant levels, a malfunctioning radiator, or a thermostat failure. Overheating can cause serious damage to your engine, so it’s essential to pull over and let the engine cool down before continuing your journey.

8. Fog Light Symbol Flickering

Your fog lights help increase visibility in poor weather conditions. If the fog light symbol is flickering, it may be a sign that your fog lights are malfunctioning or there’s an electrical issue. Make sure to have this checked, especially if you frequently drive in foggy or rainy conditions.

9. Anti-lock Brake System (ABS) Light

The Anti-lock Braking System (ABS) light indicates an issue with your car’s ABS system. This system prevents your wheels from locking up during hard braking, helping you maintain control of the vehicle. If this light stays on, you should have your ABS system inspected to ensure it’s working correctly.

10. Automatic Shift Lock or Engine Start Indicator Light

The Automatic Shift Lock or Engine Start Indicator Light signals that you need to press the brake pedal to shift the transmission out of Park or start the engine. If this light remains on or flickers, there may be an issue with the system that requires attention.

11. Seat Belt Reminder Light

This light, often accompanied by a chime, indicates that the driver or passengers haven’t fastened their seat belts. It’s essential to buckle up for safety before driving. The light will remain illuminated until all seat belts are securely fastened.

12. Airbag Warning Light

The Airbag Warning Light signals an issue with the airbag system. If this light comes on, your airbags may not deploy in the event of an accident, which is a critical safety concern. It’s important to have this checked immediately to ensure your airbags are functioning properly.

13. Security Indicator Light

This light flashes when the car’s anti-theft system is activated. If the light stays on or flashes abnormally when trying to start the vehicle, it could indicate a problem with the security system or the key fob. In some cases, this may prevent the engine from starting.

14. Washer Fluid Indicator Light

The Washer Fluid Indicator Light looks like a windshield with a stream of fluid. It means your washer fluid level is low. Maintaining sufficient washer fluid is essential for clear visibility, especially in adverse weather conditions. At Trustworthy Auto, we can quickly top off your washer fluid during routine maintenance.

15. Lane Departure Warning Light

The Lane Departure Warning Light illuminates when your vehicle detects that you’re unintentionally drifting out of your lane. If you see this light and haven’t used your turn signal, it’s a good idea to check your lane positioning or ensure that the lane departure system is functioning correctly.

16. Transmission Temperature Warning Light

The Transmission Temperature Warning Light looks like a thermometer inside a gear and signals that your transmission is overheating. High transmission temperatures can cause serious damage if not addressed promptly. If this light comes on, pull over to allow the transmission to cool and schedule an inspection at Trustworthy Auto.

What to Do When a Dashboard Light Comes On

When you see a dashboard light illuminate, the first thing to do is check the severity:

Regardless of the light, it’s always better to have it checked sooner rather than later. At Trustworthy Auto, we emphasize preventative maintenance, ensuring that small issues don’t become larger, more costly problems.
