What are my Dashboard Warning Lights Telling me?

Last Updated on 12月 20, 2021 by Carusedjp

Most modern cars have an electronic system which relies on a series of sensors. These sensors can prompt any car warning light on your dashboard, informing you that there may be something wrong with your vehicle.

Remember that there are two types of dashboard warning lights—red and orange. If the light is orange, then it means that the computer running the engine has identified an issue. You can still keep on driving. However, it is ideal that you bring your vehicle to the nearest service center to diagnose and repair the issue as soon as possible. On the other hand, if the warning light is red, then it means you need to act immediately because the issue is serious. It may mean that there is something wrong with your braking system or your engine is overheating.

In this post, we are going to discuss what your car warning light is telling you. Keep in mind that the symbols may vary, depending on the make of your vehicle. However, we will talk about the common warning lights you will see on most dashboards of cars.

Brake Fluid/Brake System

Keep in mind that your brakes are among the most important features in your vehicle. So, whether the car warning light for it illuminates in orange or red, you should not drive your car any further. Instead, you should have your braking system checked by a professional right away.

Check Engine

Usually, when the Check Engine warning light illuminates, it is accompanied by other symptoms like lack of power or intermittent stuttering when you try to accelerate. It is not advisable to drive around with this light on the dashboard. So, bring your car to a service center right away.


If the airbag is faulty, it won’t go off in the event of a crash, which means that you and your passengers do not have protection from injuries. So, when the airbag warning light illuminates, you should have it checked by a technician immediately.

EPAS/Power Steering

Also known as the EPAS light, the power steering warning light illuminates when there are issues with the steering system. You will notice that steering can be more challenging and it can be more difficult to make your vehicle change direction.

Diesel Particulate Filter (DPF)

Many vehicles have a diesel particulate filter, which is responsible for reducing emissions by removing harmful soot from the exhaust gases. If this component becomes faulty, it will trigger the warning light. Basically, it is telling you that whenever you press the accelerator, your car is releasing a toxic cloud of black smoke.


Keep in mind that the coolant is crucial in regulating the temperature of your engine. So, if its warning light is illuminating on your dashboard, then it may mean that your coolant levels are low. However, if the light is in red, it could mean a serious problem like a head gasket failure.


When the oil car warning light illuminates on your dashboard, it is likely that your oil’s temperature is too high, its pressure is too low, or you do not have enough in your vehicle. Remember that the oil is crucial in lubricating your engine. So, if you want to avoid expensive repairs, you should address the issue immediately.

Battery Charge

When you turn your car on, you will see the battery charge warning light illuminating. However, it should go out a few seconds after the engine starts. If not, then there is an issue with your vehicle’s electrical system. Several problems can be behind this. So, it is best that you bring your car to a service center right away.
