Understanding Your Vehicle’s Dashboard
Ever had a dashboard light pop on and felt a little unsure about what it meant? Don’t worry, you’re not alone! Your car’s dashboard is like its way of talking to you, and understanding those little symbols can give you peace of mind and help you catch small issues before they become big problems. At Nissan of Marietta, we believe car care shouldn’t be confusing or stressful. That’s why we’ve put together this friendly guide to help you decode your dashboard. We'll break down the most common dashboard warning lights and what they’re telling you.
What Are Standard Vehicle Warning Lights?
Standard warning lights are indicators built into your dashboard to alert you when something requires your attention. These lights can signal issues with your engine, brakes, battery, or other vital systems. While some lights are just informational, others may require immediate action.
Here are the most common categories of dashboard warning lights:
- Red Lights: Critical issues that need urgent attention (e.g., brake system, engine temperature).
- Yellow/Orange Lights: Warning signs that indicate a potential issue (e.g., tire pressure, check engine).
- Green/Blue Lights: Informational lights (e.g., headlights on, cruise control active).
The Three Most Important Lights on Your Dashboard
While all warning lights deserve attention, these three are considered the most critical:
1. Check Engine Light (CEL)
- What it means: A problem in your engine or emission system.
- What to do: If it’s steady, schedule a service visit soon. If flashing, pull over and contact a professional—this indicates a serious issue.
2. Oil Pressure Warning Light
- What it means: Low oil pressure, which can damage your engine quickly.
- What to do: Pull over and check your oil level. Add oil if needed, and call for service immediately.
3. Brake Warning Light
- What it means: There could be an issue with your brake fluid, brake system, or parking brake.
- What to do: Make sure the parking brake is released. If the light stays on, have your brakes inspected immediately.
Other Common Dashboard Warning Lights
