4.    Traction control

Another word in light has to do with the vehicle traction control system. It means that this system is activated, and it's a system that relies on the anti-lock brake system. So this warning light is very important because when it's turned on, it's activated. You should not activate the system if you're driving on slippery roads because it forces the car to act on its own to stop the vehicle in certain situations that might not be proper if you're driving on slippery roads.

Long story short, the traction control should not be activated every time, and when this is turned on, you want to make sure that you intentionally turn it on. Otherwise, you must check with your mechanic about what's happening and why it's turned on its own.


5.    Antilock brake system

There is another related warning light that has to do with the brakes as well, which is the antilock brake system. It typically says ABS. When this warning light is illuminating, it indicates that you've been braking very hard, and you should monitor how you brake and operate your car.

Once you have this error code, you can easily Google it, or depending on the scanning tool; you should get some details about the problem and potential repair costs.

Check engine light problems are very important, and those are situations where you must talk to your mechanic immediately because even if you haven't a scanning tool, you won't have to fix it. But, on the other hand, that thing might not be something you can fix, and it requires a professional to resolve.

Automotive experts always assure that you must not ignore a check engine light illuminating because the problem might be containable and can be resolved easily if you act immediately. However, if you ignore it for a couple of days or even months, things get complicated, and it might cost you a lot of money if you do not get your top where you lose the entire vehicle.

Traction Lights

7.    Battery issues

There is another warning light that looks more like a battery. The light does not necessarily mean that your battery is not functioning properly. More indicates that there is a problem with the charging system. For example, it could be an issue with the battery itself, but it can also be linked to the battery terminals, the cables, alternator, or any other component that has to do with the electric system

Whatever is causing this to be taken seriously, you must get it replaced or fixed as soon as possible. Your mechanic should be able to tell you whether you need to replace the entire component or whether you can fix it. Whatever he suggests, you should act immediately, and no matter how much it will cost, you should fix it now rather than wait for more time because things always get complicated and might impact other components you cannot afford to fix.

8.    Low fuel

You've probably seen some situations where the few indicate our lives might be illuminating because you don't have enough fuel. But, of course, cannot the easiest solution to this is to go to the gas station and fill up your gas tank.

Remember that sometimes there might be a problem with the gauge itself, and it might be illuminating because of an internal problem in the gauge. That's where you add some fuel, and you don't notice it going away.

In that situation, talk to your mechanic and see if the problem has to do with the sensor or with, the fuel tank or with some miscommunication between the vehicle computer and the fuel system,

Once your mechanic detects the faulty internal components, he should be able to provide you with recommendations about what you need to do next. For instance, if the problem is a faulty sensor or a blown fuse, go ahead and fix it before you get to situations where you think you have enough gas but don't.

9.    Automatic shift lock

Have you ever seen a symbol resembling a foot or a shoe pressing on a brake pedal? This very important warning light indicates you're having issues with the automatic shift lock. One way to resolve the issue is to never switch gears in your manual transmission without pressing the brake pedal or starting the ignition.
