Understanding Your Car’s Warning Lights: What They Mean and What to Do
Modern cars have advanced systems to keep you informed about your car’s condition. One important way they do this is through warning lights on the dashboard. Knowing what these lights mean is crucial for keeping your car in good shape and staying safe on the road. Here’s a guide to some common warning lights, what they indicate, and what actions you should take.
Check Engine Light
Symbol: An outline of an engine or the word “CHECK”
Meaning: This light suggests something is wrong with your engine or emissions system. It can be caused by issues like a loose gas cap or more serious engine problems.
What to Do:
- Check the Gas Cap: Make sure it’s tightly closed. A loose cap can trigger this light.
- Scan for Codes: Use an OBD-II scanner to find out what’s wrong.
- Visit a Mechanic: If the light stays on, make an appointment with a professional to fix the problem.
Oil Pressure Warning Light
Symbol: An oil can dripping with oil
Meaning: This light warns that your oil pressure is low, which could harm your engine if not fixed quickly.
What to Do:
- Check Oil Level: Stop and check the oil using the dipstick. Add oil if it’s low.
- Inspect for Leaks: Look under your car for oil leaks.
- Seek Professional Help: If oil levels are okay but the light is on, a mechanic should inspect the oil pump or pressure sensor.
Battery Warning Light
Symbol: A battery
Meaning: This light shows a problem with your car’s charging system, often related to the battery or alternator.
What to Do:
- Check Battery Connections: Make sure the terminals are clean and tight.

- Visit a Mechanic: If the light stays on, get the charging system checked to avoid getting stuck.
Brake System Warning Light
Symbol: An exclamation point inside a circle or the word “BRAKE”
Meaning: This light can signal low brake fluid, ABS issues, or that the parking brake is on.
