You glance at the dashboard of your car. There’s a light lingering, and it won’t turn off. 

What does it mean? Is it important? Should you pull over immediately? Can you schedule an appointment with your mechanic at your convenience? 

Why dashboard warning lights are important 

Dashboard warning lights are important because they serve as an early warning system for potential problems with your vehicle. These warning lights are designed to alert you to issues with your car’s systems before they become significant, helping prevent breakdowns and other problems that could lead to costly repairs.

When a warning light comes on, it is important to take action and have the issue diagnosed as soon as possible. Ignoring warning lights can lead to severe damage to your vehicle or even create safety hazards while driving.

Each warning light means something different. Ignore some, and you’ll have problems immediately. Others are built to give you leeway to make an appointment with your mechanic and bring it in. However, your best course of action is to act quickly.

Top 10 dashboard warning lights you should know

In general, paying attention to all dashboard warning lights and taking appropriate action when they come on is essential. Ignoring warning lights can lead to costly repairs and potentially unsafe driving conditions. If you are unsure about what to do when a warning light comes on, consult your car’s owner’s manual or take your vehicle to a reputable repair shop for diagnosis and repair.

Battery warning

The battery warning light usually indicates a problem with your car’s charging system. A dead battery, faulty alternator, or loose/damaged cables can cause this. If the battery warning light comes on, you should turn off any unnecessary electrical systems (like the radio or AC) to reduce the load on the battery and immediately drive to a repair shop to inspect the charging system.

Engine temperature warning

The engine temperature warning light indicates that your engine is overheating, which can cause significant damage if not addressed promptly. If this warning light comes on, immediately pull over to a safe location and turn off the engine to allow it to cool down. Do not attempt to open the hood or remove the radiator cap until the engine has thoroughly cooled down. Check the coolant level and refill if necessary before driving to a repair shop to inspect the cooling system.

Oil pressure warning

The oil pressure warning light indicates that the oil pressure in your engine is too low. Low oil pressure can cause engine damage, and in extreme cases, lead to engine failure. If the oil pressure warning light comes on, immediately pull to a safe location and turn off the engine. Check the oil level and refill if necessary before driving to a repair shop to inspect the oil system.

Check engine light

The check engine light is a general warning light that can indicate a variety of issues with your car’s systems, including the engine, transmission, emissions, and fuel system. If the check engine light comes on, it is vital to have the vehicle diagnosed as soon as possible to identify the underlying issue. Continuing to drive with the check engine light on can lead to further damage to your car’s systems and potentially increase repair costs.

Brake warning

The brake warning light usually indicates a problem with your car’s braking system, such as low brake fluid or worn brake pads. If the brake warning light comes on, it is important to inspect your brakes as soon as possible. Failure to address brake issues can lead to brake failure and potentially cause accidents.

Tire pressure warning

The tire pressure warning light indicates that one or more of your tires has low air pressure, which can cause uneven tire wear and affect the handling and performance of your vehicle. If the tire pressure warning light comes on, check the tire pressure and inflate any low tires to the recommended pressure before driving to a repair shop to inspect the tire pressure monitoring system.

Washer fluid indicator

The washer fluid indicator warns you when your car’s washer fluid is running low. If this warning light comes on, refill the washer fluid reservoir with the recommended fluid as soon as possible. Running out of washer fluid can make it difficult to clean your windshield and reduce visibility while driving.

Airbag indicator

The airbag indicator light usually indicates a problem with your car’s airbag system. If the airbag warning light comes on, it is vital to have the system inspected as soon as possible. A malfunctioning airbag system can cause serious injury in the event of an accident.

Power steering warning

The power steering warning light indicates a problem with your car’s power steering system, which can make it difficult to steer your vehicle. If the power steering warning light comes on, you should have the system inspected as soon as possible to avoid potential accidents.

Powertrain fault warning

The powertrain fault warning light indicates a problem with your car’s engine or transmission. If this warning light comes on, you should have your car inspected as soon as possible to prevent further damage to your car’s systems. Continuing to drive with this warning light on can cause serious and expensive damage to your car’s powertrain.

Do dashboard lights fail?

Dashboard lights can fail. Like any electrical component in a vehicle, dashboard warning lights can malfunction for various reasons, such as a blown fuse, loose connection, or a faulty bulb. Sometimes, a dirty or damaged lens may obscure the dashboard light, or the light may have burned out entirely.

If one or more dashboard warning lights are not working, it is important to have the issue diagnosed and repaired as soon as possible. Failing to address a malfunctioning dashboard light can make it challenging to monitor your car’s systems and potentially lead to more severe issues down the road. Additionally, some states require specific dashboard warning lights to function so the vehicle can pass inspection, so it is vital to ensure that all dashboard warning lights are working correctly.
