I have used the search function but cannot seem to find anything. Does the 2025-26 Yukon AT4/Denali Ultimate have auto dimming headlights? If so, how do you turn on that function?

Thanks!

Search the Owner's Manual for "High-Beam Systems". First of several paragraphs:

High-Beam Systems
IntelliBeam System


If equipped, this system turns the high-beam

headlamps on and off according to surrounding

traffic conditions.

The system turns the high-beam headlamps on

when it is dark enough and there is no other

traffic present.

A Denali shold have it, most of the higher trim models either Tahoe or Yukon it's a standard feature.
Check the owners manual for how it works. It should be on by default and only disable when you manually control the high beams or turn on the fog lights.
