Your car’s dashboard is like a communications hub. It’s where your car lights up those little icons to talk to you, a bit like the way your phone gives you notifications. Now, why should you care? Well, it’s all about keeping you safe on the road and saving you from some potentially hefty repair bills down the line.

Think of your dashboard lights as a language your car speaks. Each light, whether it’s a warning glow or a friendly green signal, has a crucial message. I’ll help you learn this language so that next time a light pops on, you won’t be left scratching your head—you’ll know exactly what your car is trying to tell you.

Ignoring your dashboard’s warnings can sometimes lead to bigger issues. If you’ve ever winced at a mechanic’s bill, you know that prevention is better than cure. By understanding what different lights indicate, you can catch problems early and deal with them before they escalate into something costlier.

The dashboard lights have different categories: warning lights that demand immediate attention, indicator lights that guide you on the functioning of certain systems, and information lights that are more FYI (For Your Information) than SOS (distress signals). We’ll delve into each type and outline common icons, such as the check engine light—everyone’s “favorite”—or the oil pressure warning, and many others.

Some alerts are urgent ‘stop-right-now’ types, while others are a heads-up for something that can be checked out soon. I’ll steer you through these differences so you can make the right call when the time comes.

At the end of the day, understanding dashboard lights is about staying informed and in control of your driving experience. So strap in, and let’s get started. And remember, you’re going to find out not just what these signals are, but also what actions you should take in response. That way, the next time your dashboard starts lighting up, you’ll handle it like a pro—calm, collected, and with a plan.

It’s important to note that some dashboard lights are not entirely universal in terms of their appearance and meaning across all car makes and models. While many symbols are standardized, there can still be variations in the design and specific meanings of certain indicators depending on the manufacturer, hence it’s always a good idea to consult your vehicle’s owner’s manual for specific information about the dashboard lights in your car. However, there are some common dashboard symbols that are widely used and understood across many vehicles, they are the ones we will mainly focus on. 

Warning lights

Typically red or amber in color, these lights alert you to critical issues with the vehicle’s systems. They prompt immediate action to diagnose and address problems, preventing further damage and maintaining safe operation of the vehicle.

Check engine light

The check engine light warns you of a problem with the vehicle’s engine or emissions control system. It indicates the need for diagnostic testing and repair to prevent further damage and ensure proper engine performance and fuel efficiency.

Oil pressure light

The light warns you of low oil pressure, which can lead to engine damage if not addressed promptly. It indicates the need to check the oil level and top up without delay.​

Temperature light

The light indicates engine overheating and you need to take immediate action when it shows up. Safely pull over to the side of the road, turn off the engine, and allow it to cool down. Check coolant levels once the engine has cooled, top up if they are low. Do not continue driving until the issue is resolved otherwise the engine will be damaged.

Battery light

The battery light warns of problems with the vehicle’s charging system, such as a failing alternator or battery. You must have the electrical system checked by a mechanic, as the problem could be a faulty alternator, loose connection, or a dead battery that needs replacement.

Brake warning light

The light indicates problems with the braking system like low brake fluid or a malfunction. You should check brake fluid levels, inspect brake pads, and seek professional inspection if needed.

ABS (Anti-lock braking system) light

The ABS light indicates an issue with the Anti-lock braking system. This is the system that prevents wheels from locking up during breaking. To resolve it, check ABS fuse, sensors, and connections. If the issue persists, seek professional diagnosis and repair.

Airbag light

The airbag light indicates a fault in the airbag system, compromising safety. When it turns on, first ensure all seat belts are fastened properly. If the light stays on, have the system inspected by a professional to diagnose and repair any issues.

Tyre pressure monitoring system (TPMS) light

The light alerts you to low tyre pressure. Check and adjust tyre pressures to the recommended levels. If the light persists, have the system inspected for malfunctions.

Lane departure warning light

The light alerts you when your vehicle drifts out of its lane without signaling. This safety feature helps prevent accidents caused by distracted or drowsy driving, prompting you to take corrective action and maintain proper lane positioning to enhance road safety and prevent collisions.

Information lights

These ones provide you with non-critical vehicle status updates, such as the activation of driver assistance features, to enhance awareness and support safe and informed driving.

Cruise control light

The cruise control light indicates when the cruise control system is active and maintaining a set speed without constant accelerator input. It visually confirms to the driver that cruise control is engaged, enhancing driving comfort and convenience on highways.

Blind spot monitoring light

The blind spot monitoring light is a safety feature in vehicles that alerts the driver when there is a vehicle or obstacle in their blind spot, which may not be visible through the side or rearview mirrors. The light typically illuminates or flashes on the side mirrors or dashboard to warn the driver of potential hazards when changing lanes or making turns. This system helps drivers make safer lane changes and reduces the risk of collisions caused by blind spots.

Automatic high beams light

The automatic high beams light indicates when the vehicle’s automatic high beam system is engaged. This system detects oncoming vehicles or vehicles in front and switches between high and low beams accordingly to provide optimal visibility for the driver without blinding other drivers on the road.

Traction control light

Traction control helps prevent wheel slip during acceleration by modulating brake and engine power, hence the traction control light alerts you when the system is actively preventing wheel slip. To solve traction control issues, ensure tires are properly inflated and have good tread depth. Drive cautiously on slippery surfaces. If the light stays on, have the system checked by a mechanic to diagnose any potential issues.

Electronic/Dynamic stability control (ESC/DSC) light

Stability control helps drivers maintain control of their vehicles during sudden maneuvers or loss of traction. To solve stability control issues, ensure tires are in good condition, drive cautiously, and have the system checked by a professional if the light persists to ensure safe operation.

Adaptive cruise control light

Adaptive cruise control goes beyond standard cruise control by using sensors, such as radar or cameras, to monitor the distance and speed of vehicles ahead. It automatically adjusts the vehicle’s speed to maintain a safe following distance from the vehicle in front. The adaptive cruise control light signals when this feature is engaged and actively adjusting the vehicle’s speed based on traffic conditions. When it is red as above it indicates that the function is unavailable.

Indicator lights

These are the lights that visually confirm the activation of various auxiliary functions, such as turn signals, fog lights, and parking sensors, helping the you monitor the vehicle’s operational status.

Fog light indicator

The fog light indicator shows when the fog lights are switched on, improving visibility in foggy or misty conditions.

Front/rear parking sensor light

Parking sensor indicator lights alert drivers to obstacles or objects in their vehicle’s path while parking. These lights provide visual cues, often through color changes or beeping sounds, to help drivers navigate and park safely, preventing collisions and damage to the vehicle.

Parking break indicator light

The parking brake indicator light alerts drivers when the parking brake is engaged or not fully released, preventing driving with the brake on and avoiding potential damage or safety risks.
