Fu
nction of the off-road light
The off- road light impr oves illumination during
off-road driving. The low beam is distributed
symmetrically and across a wide angle, and
brightness is increased slightl y.This makes it
easier tofind your wa y when driving off- road and
to detect obs tacles at an ea rly st age. The active
headlamps are deactivated during this time so
th at steering mo vements do not change the illu‐
mination.
The function is active when the low beam is
switched on if you are not driving at a speed
greater than 50 km/h and theF (Offroad) or
G (Offroad Plus) drive program has been
selected.
