What Do the Warning Lights on My Car Mean?
Nissan Dashboard Warning Lights & Meanings
When a warning light suddenly appears on your Nissan dashboard, it can be stressful. Whether you see a yellow exclamation mark, red brake symbol, or the car with squiggly lines, understanding what each alert means helps you respond quickly and safely. Our experts at McGrath Nissan of Elgin explain the most common Nissan dashboard warning lights and symbols, what to do next, and when to visit our certified service center in Elgin, IL, near Schaumburg, Hoffman Estates, Carpentersville, and St. Charles.
Yellow vs. Red Dashboard Warning Lights
The color of your dashboard light can tell you a lot about the urgency of the issue:
- Red lights mean stop immediately — your vehicle needs service right away to prevent damage or safety risks.
- Yellow or orange lights indicate something needs attention soon, like tire pressure, emissions, or traction control.
If you’re ever unsure, our Nissan service experts in Elgin can inspect your vehicle and clear the code safely.

FAQ: Nissan Dashboard Lights
What does the yellow exclamation mark on my Nissan mean?
That’s the TPMS tire pressure warning. Inflate all tires to the correct pressure, and the light should clear after driving a few miles.
What does a circle with an exclamation mark inside mean?
This is the brake warning light. Ensure the parking brake is released and the brake fluid is at the proper level.
What does the car with squiggly lines light mean?
It’s the traction control/VDC light. Flashing is normal; if it stays on, schedule service for a diagnostic check.
Is a red exclamation mark serious?
Yes. Stop driving as soon as it’s safe. It may signal a brake, oil, or transmission issue.
Why is a red car icon flashing on my Nissan’s dashboard?
That’s the security indicator. Flashing when parked is normal, but solid while driving indicates a fault.
