No, it is decoded for US as is anti-dazzle. It is more complex than just turning the lights:
Here is a more detailed explanation about VLD found in Coding Threat thanks to opasha
Variable Light Distribution has several different modes of operation (for Low Beam):
1 - City Light: Shallow and Very Wide Beam Pattern active from 0 - 50kph (30MPH) (Both Headlamps are Panned outwards 12 horizontal from center and 0.7 lowered vertically)
2 - Standard Light: Same Basic Beam Pattern as with 8S4 Enabled and Headlamp Switch Set to Auto. Active from 50 - 110kph (30MPH - 68MPH)
3 - Guiding Fog Light - Shallow and Wider Beam Pattern Enabled with the Front Fog Lamps On and Headlamp Switch in Auto and Speed 0 - 110kph (Both headlamps are panned outwards 8 horizontal from center and lowered 0.7 vertically)
4 - Highway Light - Long Throw Pattern illuminating approx. 25% further than Standard Light. Active from 110 to 250kph (68MPH- 155MHP). (Driver's Side Headlamp is panned 3.5 outwards Horizontal from center and lowered 0.25 vertically, while the passenger side headlamp is raised 0.2 vertical) (thank you @shawnsheridan)
Clarification of VLD, HBA, and Anti-Glare/Anti-Dazzle (thank you @skalberti):
VLD is Variable Light Distribution - It only works on your low beams to move your headlights and position the beams on the road depending on steering angle and vehicle speed.
HBA is High Beam Assistant - USA spec high beams that turn off in the presence of headlights or taillights of other cars and automatically turns the high beams on if no other cars are present.
Anti-Glare, Anti-Dazzle - European spec high beams that enable your car to keep the high beams on without blinding other cars.
