Exterior lighting
142
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
you are driving. This allows you to recognise
pedestrians, cyclists and animals.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane
in which you are driving and adjusts the light
in advance.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
if you are driving at speeds below 40 km/h
R
and switch on the turn signal or turn the
steering wheel.
if you are driving at speeds between
R
40 km/h and 70 km/h and turn the steer-
ing wheel.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on
both sides before entering a roundabout
through an evaluation of the current GPS
position of the vehicle. It remains active until
after the vehicle has left the roundabout. In
this way, pedestrians crossing the road, for
example, are illuminated by your vehicle in
good time.
Motorway mode
Active: if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1,000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
