What Do Dashboard Warning Lights Mean?

Not all dashboard lights indicate immediate danger, but it’s essential to address them early. If you're in Rockwall, Texas, Rowlett, Texas, or nearby areas, visit McSwain Automotive for a diagnostic scan and professional repair. Here are some of the most common dashboard lights and what they mean:

• Oil Pressure Light: Indicates oil isn't circulating properly. IT could be due to low oil, a worn pump, or internal engine wear.

• Tire Pressure Warning Light (TPMS): Alerts you to under- or over-inflated tires. Faulty sensors may also trigger this light.

• Engine Temperature Warning: Signals engine overheating. If this turns on, pull over immediately to prevent engine damage.

• Traction Control Light: Indicates reduced traction or slippery conditions. This system applies brakes to help control skidding.

• Check Engine Light: Could mean a range of issues, from a misfire to a loose gas cap. If it flashes, call McSwain Automotive at 972-772-3830 immediately.

• Battery Alert Light: Suggests a problem with your charging system, could be your battery, alternator, belt, or cables.

• Washer Fluid Indicator: A simple alert that your windshield washer fluid is low.

At McSwain Automotive, we run full diagnostics to identify what’s triggering the light and recommend the right solution, no guesswork involved.
