What Your Car Dashboard Symbols Mean
Your car’s dashboard is more than just a place to check your speed or fuel—it’s your vehicle’s way of communicating with you. When warning lights appear, it’s important to know what they mean and how to respond. At R&S Auto in North York, ON, we want to help you stay safe on the road by explaining the most common car dashboard symbols and why they shouldn’t be ignored.
Why Dashboard Warning Lights Matter
Modern cars are equipped with sensors that monitor everything from oil levels to brake systems. When something isn’t working properly, a car warning light will appear on your dashboard. Some lights are just reminders or alerts, while others require immediate attention and mean you should stop the car as soon as it’s safe.
Categories Of Dashboard Warning Lights
Most dashboard lights fall into three categories based on colour:
- Red lights: Indicate a serious issue. You should stop the car immediately.
- Yellow/Orange lights: Signal caution—check the issue soon.
- Green/Blue lights: Typically indicate a system is active (e.g., high beams or cruise control).
Common Dashboard Symbols And What They Mean
Here are the top symbols you might see and what you should do when they light up.
1. Check Engine Light
This symbol looks like an engine and can appear for many reasons. It could be something minor like a loose gas cap, or more serious like a misfiring engine. While your car may still drive normally, it’s best to book an appointment at R&S Auto to have it diagnosed.
- A flashing check engine light means the issue could cause damage—stop the car if this happens.
2. Engine Temperature Warning Light
This light looks like a thermometer dipped in liquid. It means your engine is overheating. Pull over safely and turn off the engine.
- Check coolant levels once the engine cools down.
- Running an overheated engine can cause serious damage.
3. Oil Pressure Warning Light
Shaped like an old-fashioned oil can, this light means your engine may not be getting enough oil.
- Pull over and check the oil level.

A red exclamation mark in a circle often signals a problem with your brake system.

This light looks like a car with squiggly lines underneath. It means your stability control or traction control system is engaged.
