How to Read and Respond to Dashboard Warning Lights
Modern vehicles are designed to communicate potential issues clearly, and your dashboard warning lights are one of the most important tools your car uses to keep you informed. Understanding what these warning lights mean can help you avoid costly repairs, stay safe on the road, and know when it’s time to visit a trusted service center like Art Morse Auto Group.
Whether you’re driving a new model or a used vehicle, this guide explains the most common dashboard warning icons, which ones require immediate attention, and what actions drivers should take.
Why Dashboard Warning Lights Matter
Dashboard warning lights alert you to changes in your vehicle’s systems, from low fluid levels to serious mechanical or safety concerns. Ignoring these lights can lead to breakdowns, reduced performance, or unsafe driving conditions. Knowing how to read dashboard warning lights empowers you to respond quickly and protect your vehicle’s long-term reliability.
Most Common Dashboard Warning Lights and Their Meanings
Check Engine Light
What it means: A problem with the engine, emissions system, or sensors. Urgency: Medium to high. What to do: If the light is steady, schedule a diagnostic service soon. If it’s flashing, reduce speed and seek immediate service.
Oil Pressure Warning Light
What it means: Low oil pressure or insufficient lubrication. Urgency: High. What to do: Pull over safely and turn off the engine. Driving with low oil pressure can cause severe engine damage.
Battery / Charging System Light
What it means: The battery isn’t charging properly, often due to alternator issues. Urgency: Medium. What to do: You may be able to drive briefly, but schedule service promptly to avoid a dead battery.
Brake Warning Light
What it means: Low brake fluid, worn brake components, or parking brake engaged. Urgency: High. What to do: Check that the parking brake is released. If the light stays on, have your brakes inspected immediately.
Tire Pressure Monitoring System (TPMS) Light
What it means: One or more tires have low air pressure. Urgency: Low to medium. What to do: Inflate tires to manufacturer-recommended PSI and inspect for leaks.
Engine Temperature Warning Light
What it means: The engine is overheating. Urgency: High. What to do: Stop driving as soon as it’s safe and allow the engine to cool. Continued driving can cause major engine damage.
Which Dashboard Warning Lights Are Urgent?
Red warning lights generally indicate serious issues that require immediate action. These often include:
- Oil pressure warnings
- Brake system warnings

Yellow or amber lights typically signal caution. While not always urgent, they should never be ignored and usually mean it’s time to schedule service.
