Car Dashboard Lights & Symbols Meanings

The car dashboard warning lights and symbols are quite indispensable in keeping the driver updated about the status of his or her vehicle and any possible faults. Understanding what the car dashboard warning lights mean will help you get the problems fixed promptly to avoid costly repairs, and most importantly, stay safe while driving. In this article, we discuss common dashboard warning lights, including the notorious check engine light, and their meanings.

What Are Dashboard Lights?

Dashboard lights are warning indicators on your car’s dashboard. They light up to bring to your attention certain conditions or malfunctions in the vehicle. The lights are color-coded to some degree to show their urgency:

• Red Lights: These mean you have serious problems that need immediate action, such as an overheating engine.
• Yellow/Amber Lights: These are cautionary and usually associated with maintenance or performance, such as a check engine light.
• Green/Blue Lights: These are informational lights that indicate which system is in operation, such as the headlights or cruise control.

Common Car Dashboard Symbols and Meanings

Check Engine Light

The check engine light is probably the most iconic car warning light. It is usually yellow or amber and engine-shaped. When this light comes on, it could be one of many things, including:

• Loose or damaged gas cap
• Malfunctioning oxygen sensor
• Engine misfire
• Catalytic converter problems

If it’s flashing, that means you have a serious problem, and you need to pull over and get assistance immediately.

Oil Pressure Warning Light

This red light, shaped like an oil can, indicates low oil pressure. It could be an indication that your car is low on oil or that there’s a problem with the oil pump. If you ignore this warning, you’ll be taking a serious risk of damaging your engine.

Battery Warning Light

Red in color and battery-shaped, this light signals a problem with your charging system. The usual suspects in such cases are either a failing alternator, loose cables, or a worn-out battery. Getting it repaired as soon as possible will help your car electrical systems function properly.

Brake System Warning Light

Often accompanied by an exclamation mark inside a circle, this light might signal various conditions related to brakes, such as:

• Low level of brake fluid

• Antilock Braking System failure
• Parking brake engaged

If this light comes on while driving, pull over and check your brakes immediately.

Temperature Warning Light

This red, thermometer-shaped light indicates your engine is overheating. The most common causes include low coolant levels, a bad thermostat, or a radiator problem. Turn the engine off and let it cool before checking the coolant.

Transmission Temperature

That would indicate that your gearbox internal parts are reaching a critical point. It could be brought on by overloading at the towing end, low transmission fluid level, or more seriously, severe wear in the inner parts of the transmission.

Tire Pressure Monitoring System (TPMS) Light

This yellow light, in the shape of a horseshoe with an exclamation point, signals low tire pressure. Check your tires and inflate them to the recommended levels by the manufacturer for safe driving and the best fuel efficiency.

Airbag Warning Light

This warning light, shaped like a person sitting with an airbag, indicates a fault in the airbag system. An automobile without an operational airbag can be very unsafe in case of a crash.

Fuel Level Warning Light

This yellow light, shaped like a gas pump, warns you when fuel is low. Fill up the tank as soon as possible to avoid running out of gas.

Other Important Car Light Symbols

Headlight Indicators: Green or blue lights indicate when your headlights, high beams, or fog lights are on.

Traction Control Light: Indicates that the vehicle’s traction control system is engaged to provide grip.

Stability Control Light: Warns of possible skidding or loss of control.

What to Do When Car Warning Lights Appear

Don’t Ignore the Light: Pay attention to the color and symbol of the light.

Check the Owner’s Manual: Refer to your car’s manual for specific car dashboard symbols and meanings.

Perform Basic Checks: Inspect fuel, tire pressure, oil levels, or other easily accessible components.

Seek Professional Help: If you’re unsure or the issue persists, visit a mechanic to diagnose and fix the problem.
