Only when in motion I think

PS - From the owners manual

Active Xenon headlamps*
If the car is equipped with
active Xenon headlamps
(Active Bending Lights, ABL)
the light from the headlamps
follows the steering wheel
movement during driving. The
function is activated automatically when the
car is started and can be deactivated/activated
by pressing the button. The lamp in the button
illuminates when the function is activated

Cheers

Dave
