Advanced main-beam control (Dynamic Light Assist) provides maximum illumination for the road and the edges of the road. At the
same time, it prevents vehicles in front or oncoming vehicles from being dazzled. The system uses a camera to detect other self-
illuminated road users and their distance from your vehicle and deactivates areas within the light distribution in a targeted manner. If
the system can no longer prevent other road users from being dazzled, main beam is switched off completely. Dynamic Light Assist
normally also recognises illuminated areas such as towns and deactivates main beam while driving through them.
Within the limits of the system, main beam is automatically switched on or off depending on the surroundings and traffic conditions
and on the driving speed →
.
Dynamic Light Assist can be activated and deactivated in the vehicle settings in the Infotainment system (→ Vehicle settings menu).
Switching on Dynamic Light Assist
1. Switch on the ignition.
2. Switch on automatic lighting control
(→ Dipped beam).
3. Tap the lever forward from the basic position → Fig. 1 A .
When Dynamic Light Assist is activated, the
indicator lamp lights up white in the instrument cluster display. When Dynamic Light
Assist is switched on, the
indicator lamp for main beam lights up blue in the instrument cluster.
Switching off Dynamic Light Assist
1. Switch off automatic lighting control
(→ Dipped beam).
if Dynamic Light Assist is switched on and active, pull the lever back → Fig. 1 B .
if Dynamic Light Assist is switched on and not active, tap the lever forward → Fig. 1 A . Manual main beam is now switched
on. To switch off the manual main beam again, pull back the lever.
Additional IQ.LIGHT functions
Depending on equipment, the headlights are equipped with additional IQ.LIGHT functions that increase convenience and safety.
—Lane light:
If the system has detected that the vehicle is driving on multi-lane motorways or similar roads, the lane light illuminates the full
width of the vehicle’s driving lane. If vehicles driving in front are detected, the length of the illuminated range is automatically
reduced. If the vehicle changes lane, the illuminated range is extended to both lanes for the duration of the manoeuvre.
—Orientation light:
If the system has detected road works or narrow road sections, the orientation light uses markings to approximately show the
probable vehicle position in its lane depending on the current steering angle. The width of the markings corresponds approximately
to the vehicle width, but they do not reproduce it exactly. The length of the markings is adjusted automatically depending on the
speed and distance to vehicles driving in front.
The additional IQ.LIGHT functions can be activated and deactivated in the vehicle settings in the Infotainment system.
System limits
The main beam must be manually switched off under the following conditions, as it is not switched off by Dynamic Light Assist in time
or not at all:
—In badly lit towns that the system cannot recognise as towns.
—In poorly lit streets where there are highly reflective signs.
—Other road users with insufficient lighting facilities, such as pedestrians, cyclists.
—In the case of crossing traffic at right-angled junctions.
—In tight bends, on steep hill crests or in dips in the road or when oncoming traffic is half-hidden.
—With oncoming traffic on streets with a central barrier where the driver can see clearly over the central barrier e.g. truck drivers.
—In fog, snow or heavy rain.
