ADS Off Hyundai – Causes And Troubleshooting Tips

An ADS off Hyundai issue can be an inconvenience.

After all, you need your anti defogging system to work when you are dealing with foggy windows. For example, you are in an area where the winters are extremely cold, which means you need to use your heater to warm the car. But the result is creating fog on the inside part of your windows.

And when it is humid outside, the moment you turn the AC on, fog ends up blurring the windows from the outside. With this in mind, you want to do all you can to eliminate or minimize the issue with fog to avoid having issues with your driving.

Now, your windows fog up because of the moisture content in the air and the temperature. When it is cold, moisture in the air within your vehicle turns into condensation once it reaches the air next to your windows, which is under a particular temperature. This then causes the fog. 

Whether the issue with fog is outside or inside your windows, one problem remains – it is difficult to have a clear vision of all directions when you drive. Hence, this can get quite risky, which gives you some problems when you drive.

With that being said, let us talk about what you can do to solve this issue, especially if you are dealing with an ADS off Hyundai problem. Let’s get right into it.

What Does Ads Off Mean Hyundai

Your Hyundai vehicle is equipped with an auto defogging system or ADS, which helps to minimize the chances of fogging up inside your vehicle. This system senses moisture inside, which then helps to clear the fog. 

Moreover, it operates when you have the AC or the heater turned on. This ADS light turns on once it senses moisture inside. So, if there is too much moisture in the vehicle, it should automatically help clear it out.

But if your ADS is off, then you can try these steps:

  • Outside air position
  • Blow air toward your windshield
  • Increase the air flow to your windshield
  • Operate your AC
  • Increase the AC level

It is worth noting that your auto defogging system is only activated once the required conditions are met. But if you wish to cancel your ADS and turn it off, you need to press and hold the front defroster button up to 4 times as you also press the auto button. 

Then, you will notice that the indicator of your front defroster button will start to blink thrice to let you know that it has been cancelled. If you wish to turn it on once more, you need to press and hold the button.

Furthermore, if you have your battery discharged or disconnected, this also resets your auto defogging status. 

In case the AC is turned on by your auto defogging system, then you wish to turn the AC off, you will see the indicator blinking thrice and your AC will not turn off. This is why for better efficiency, avoid selecting the recirculated air position while you have the auto defogging system running.

Hold your defogger button for a couple of seconds, and you will notice the ADS notification will start to flash and disappear. Release the button and press your front defrost once more, and this should turn the ADS off.

As an alternative, you can also control this from your BlueLink app. When hitting start, it takes you to a screen with a few presents, allowing you to change the temperature settings. Otherwise, a reset should either turn the ADS off or on.

Bottom Line

Your vehicle’s auto defogging system is helpful when you have a lot of condensation in your vehicle, which obstructs your view of the outside. This is why it is best to turn the system on following the steps we have mentioned, so you can have an easier experience in driving your vehicle while keeping safe on the road. At the same time, you can also maintain the optimal temperature in your vehicle for your comfort and convenience.
