•OR: push the turn signal and main beam lever forwards to switch on the manual main beam.
Advanced main-beam control (Dynamic Light Assistyf
Advanced main-beam control provides maximum illumination for the road and the surrounding area.
At the same time, it prevents vehicles in front or oncoming vehicles from being dazzled. The system
uses a camera to detect other road users and their distance from your vehicle and covers part of
the headlights appropriately. If the system can no longer prevent other road users from being
dazzled, the main beams are switched off automatically.
System limits
The main beam must be switched off manually under the following conditions because it is not
switched off in time or not switched off at all by the main beam control:
•In poorly lit streets where there are highly-reflective signs.
•Other road users with insufficient lighting facilities, such as pedestrians, cyclists.
•In tight bends, brows of hills or depressions in the land or half-hidden oncoming traffic.
•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.
•In dusty or sandy areas.
•Damage to the windscreen in the camera's vision field.
•If the viewing field of the camera is misted up, dirty, covered by a sticker, snow or ice.
•If the camera is broken or the power supply is interrupted.
Light-emitting objects in the camera's field of operation, e.g. mobile navigation devices, could
impair the functions of the main-beam control system (Light Assistyf .
Parking light
Switching the parking lights on and off
Do not let the extra convenience afforded by main beam control tempt you into taking any
risks when driving – this can cause accidents. The system is not a substitute for the full
concentration of the driver.
•Always check the lights yourself and adjust them to the prevailing conditions for lights,
vision and road traffic.
•The main beam control may not be able to recognise all driving situations correctly and
may not work properly in certain situations.
•If the camera's field of view is dirty, covered or damaged, the function of the main
beam control may be impaired. This also applies if changes are made to the vehicle's
lighting system, for example if additional headlights are fitted.
WARNING
Please observe the following points in order to avoid impairing the proper function of the
system:
•Regularly clean the camera's field of view, and keep it free from snow and ice.
•Do not cover the camera's field of view.
•Regularly check the area of the windscreen that is in the camera's field of view for
damage.

Automatic switch-off for side lights and parking lights
The side lights and parking lights drain the 12-volt vehicle battery when switched on. In order to
ensure that the engine can be started, the side lights and parking lights are automatically switched
off when the charge level of the 12 V vehicle battery is so low that there is a risk of no longer being
able to restart the vehicle. Switch-off takes place at the earliest after the side and parking lights
have been switched on for two hours.
The side lights and parking lights will not switch off automatically if there is insufficient battery
capacity for them to remain switched on for two hours. In this case, the side lights and parking lights
will remain switched on until the 12-volt vehicle battery is fully discharged. It will no longer be
possible to restart the engine ⇒.
