Mine on the Ateca so you'd have to be doing illegal speeds for that to kick in. Seem to recall the wiper blades did fun things on unrestricted Autobahn. They stop at the top or something. Park at the side. Grey matter.

I did come across a Dutch discussion on this and it seems you can’t change it from 140km/h

Wonder why Seat changed it from 110km/h to 140km/h…..
.
Just found another Spanish forum confirming you can’t change it

This thread implies you can change it, but need to switch to a “developer session” somehow first ?

[SEAT] [Leon 5F] Snelwegverlichting, inschakelsnelheid aanpassen
Op mijn Seat Leon ST 5F heb ik de Full-LED koplampen en Technology upgrade zitten en daarmee dus ook de optie 'Snelwegverlichting'. Dit houdt in dat bij een snelheid van 140 km/u het dimlicht iets verder naar voren gaat schijnen. Nu heb ik via OBD11 de optie gevonden om de snelheid aan te...

I’ll have a play later and see if I can find this Developer Mode for the control module 09.
Update:
Managed to change it !!
You do indeed need to enable ‘Developer mode’ for the module that is under the ‘Change service’ tab.
I tried to set 75km/h on and 20s delay off…
But these were the lowest values it showed after saving.
Tried again and it did the same
100km/h on
50s delay off
Will have a drive later and see if I notice anything

Ah similar to the developers menu on the high then. That's to protect it from wandering fingers.
Ok so just been out to test this, and I can confirm I noticed NOTHING 
I’ve got a long stretch of quiet, straight, flat, unlit sDual Carriageway near me.
Got on it, set Cruise control to 70mph (so way past the 100km/h I’ve set for this)
Counted eagerly for the 10secs delay to elapsed and looked carefully at the beam…..
Nothing.
My guess it’s that this setting will in fact turn just turn on the headlights during the day if the specified speed/duration are met.
It fact that makes sense if you think about the default setting of 120s delay to turn off.
If the lights did angle up 5% or degrees on the motorway, you’d want them to angle back down a lot quicker than 120s if you left the motorway.
Makes me wonder if there is an elusive setting buried somewhere for these 110km/h “Motorway lights” that we don’t know about or nobody has found.
