Cornering light function with traffic circlefunction:
The cornering light function is activated onboth sides before entering a traffic circlethrough an evaluation of the current GPS posi-tion of the vehicle. It remains active until afterthe vehicle has left the traffic circle. In thisway, pedestrians crossing the road, for exam-ple, are illuminated by your vehicle in goodtime.
Active light function
The active light function is a system thatmoves the headlamps according to the steer-ing movements of the front wheels. In thisway, relevant areas remain illuminated whiledriving. This allows you to recognize pedes-trians, cyclists and animals sooner.
Active:when the lights are switched on.
Vehicles with Lane Keeping Assist: the activelight function evaluates the course of the lanein which you are driving and pre-emptivelycontrols the active light function.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlampsto change between low beam and high beamautomatically. The system recognizes vehicleswith their lights on, either approaching fromthe opposite direction or traveling in front ofyour vehicle, and consequently switches theheadlamps from high beam to low beam.
The system automatically adapts the low-beamheadlamp range depending on the distance tothe other vehicle. Once the system no longerdetects any other vehicles, it reactivates thehigh-beam headlamps.
The system's optical sensor is located behindthe windshield near the overhead controlpanel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recog-
nize road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be
deactivated or will be activated regardless.
There is a risk of an accident.
Always carefully observe the traffic condi-
tions and switch off the high-beam head-
lamps in good time.
Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. Youare responsible for adjusting the vehicle'slighting to the prevailing light, visibility andtraffic conditions.
In particular, the detection of obstacles can berestricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain orsnow
Rdirt on the sensors or the sensors areobscured
