GMC Dashboard Warning Lights And Symbols Meanings

GMC vehicles are equipped with a range of dashboard warning lights and symbols that alert you to potential issues with your vehicle. Understanding these lights is essential for maintaining the safety and performance of your truck or SUV. At Fairway GMC, we want to ensure that you are well-informed about your vehicle’s warning system so you can take quick action when necessary. In this article, we’ll cover some of the most common GMC dashboard warning lights and what you should do when you see them.

1. Check Engine Light (CEL)

The Check Engine Light (CEL) is one of the most common and important warning lights you’ll encounter. It can indicate a variety of issues, ranging from minor problems like a loose gas cap to more serious concerns like an engine misfire or a faulty oxygen sensor. When this light appears, it’s important to have your vehicle scanned for error codes to pinpoint the exact problem. If the light is flashing, it typically indicates a more serious issue that requires immediate attention.

2. Oil Pressure Warning Light

This symbol looks like an oil can and is a critical alert. If this light comes on while driving, it typically means that your engine oil pressure is low, which can lead to severe engine damage if not addressed quickly. Pull over safely and turn off the engine, then check the oil level. If it’s low, top it off and check for any leaks. If the light remains on after adding oil, you should contact a mechanic as it could indicate a more serious issue.

3. Battery Charge Warning Light

The Battery Charge Warning Light indicates a problem with your vehicle’s charging system. It may suggest an issue with the alternator, battery, or wiring. If this light comes on while driving, it’s important to have your battery and alternator checked immediately, as continued driving could lead to a dead battery, leaving you stranded.

4. Tire Pressure Monitoring System (TPMS) Light

The TPMS Light comes on when one or more of your tires are under-inflated. Proper tire pressure is essential for safety, fuel efficiency, and tire longevity. When this light appears, stop to check the tire pressures and inflate any tires that are low. If the light remains on even after inflating the tires, there may be a malfunction with the system, requiring a visit to a professional.

5. Brake Warning Light

The Brake Warning Light can mean a few different things, ranging from low brake fluid to an issue with the braking system. If this light comes on, check your brake fluid level first, as low fluid could indicate a leak. If the light remains on, or if it appears alongside other brake-related symbols, such as the ABS warning light, it’s essential to have the brakes inspected immediately, as this could indicate a serious safety issue.

6. ABS Warning Light

The ABS (Anti-lock Braking System) warning light indicates an issue with your vehicle’s anti-lock brake system. While your brakes will still work, the ABS system may not function properly. This light could mean a problem with the ABS sensor, wiring, or another part of the braking system. If this light comes on, it’s best to have your truck checked as soon as possible to ensure safe braking.
