Intelligent Light System* (bi-xenon
headlamps*) The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 106). Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Motorway mode
Motorway mode increases the range of the
beam.
Active:
R
If you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m.
R If you are driving at speeds above
130 km/h.
Motorway mode remains active unless your
speed drops speeds below 80 km/h.
Not active: if you are driving at speeds below
80 km/h. 82
