Automatic Lights Sensitivity

I don't believe anyone has asked this question before, but is there a way to adjust the point at which the auto headlights switch on? While driving at dusk it has to get really quite dark before the lights switch on by themselves. Several times now I've waited and waited until every car I see coming the other way has their lights on and still nothing from the i30N. The do come on eventually but it kinda defeats the purpose of the auto function if you always have to do it manually.

I think it should be changable if you have the right OBD coding tools but no guarantee on that.

It is annoying and something I noticed straight away, the helpful response I got on here was basically "Whats your problem? Just switch the stalk up and turn them on yourself". :D

I agree with you that you shouldn't need to do that, I was thinking about putting a small square of headlight tint film over the sensor and see if that helps them come on quicker?!

Like your thinking here, simple and worth a crack.

That is the one thing that annoys me about this car, comming from a Skoda Vrs where I could adjust the sensitivity of the sensor.
Looking around at other Kia's and Hyundai's they all seem to have the same problem. All the cars allready have their lights on, except the Hyundai's and Kia's.

Any joy using the film?
It was almost impossibe to apply neatly due to the sensor location (unless you have the windscreen removed, didn't fancy that :p ) and looked obvious/terrible.

Mission aborted!!

Removing the sensor completely to apply the film off the car was also impossible due to its location and windscreen inhibiting my clumpy hands/lack of leverage.



(Weirdly I'm positive the auto lights seem to be more sensitive than they were a few months back......o_O)

Maybe it would be possible to tint the screen just at the sensor, doable?

The sensor is the one in the middle of the dash isn't it ( where the alarm LED is) - that's what the manual seems to suggest?

Weird that you mention about them being more sensitive but I have noticed the same thing. I know objectively that they are because when I drive under an archway by my house they activate whereas before they wouldn't even at dusk. Maybe they applied a software update / reset during the alarm visits.

Yes, middle of dash right tight up near the windscreen and it incorporates a "security" LED (nothing to do with alarm, just a dummy flashing light to show car has been locked).

Be nice if they also auto activated during heavy rain so I don’t have to manually switch them over. Every other car I’ve had with auto wipers and lights used to do this.

Agreed, its a safety feature in my opinion and my Golf had a setting you could toggle lights auto on/off when auto wipers activated.

I don't have wipers or lights set to 'Auto' at all. I'd prefer to switch them off and on when I think it's required. Having headlights turn on and off every time I drive under a bridge or overpass would be annoying. I see it happen on other cars.

In saying that, at night time I generally just switch the lights to 'Auto' anyway then turn them off once I've arrived at my destination.

One think I have noticed is that there must be 2 separate light level sensors - one for the headlights and a separate one for the dashboard dials and audio/navigation screen, as these seem to dim/turn off independently to each other

Nope, Hyundai GDS not have any function for this, only reset the module. I think only factory system configurator, or development softwares can change the values of the sensor.
