In vehicles with a corresponding equipment level, main-beam control can be activated and
deactivated in the Infotainment system in the Vehicle settings menu ⇒ Operation and
display in the Infotainment system:
Switching on main beam control
•Switch on the ignition and turn the light switch to position .
•Tap the turn signal and main beam lever forwards out of the basic position.
When the main-beam control is switched on, the indicator lamp is shown on the instrument
cluster display.
Switching off main beam control
•Pull back the turn signal and main beam lever.
•OR: turn the light switch to a position that is not .
•OR: switch off the ignition.
•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.
NOTICE
Switching on start/stop
The function is automatically activated every time the ignition is switched on. The instrument cluster
display will show information about the current status.
Vehicles with DSG dual clutch gearbox may be equipped with a start/stop system with engine-off
coasting function. The engine-off coasting function is deactivated and activated together with the
start/stop system.
Further information regarding start/stop mode is available in the Infotainment system ⇒ Operation
and display in the Infotainment system. This information also applies to coasting.
Indicator lamps
If the indicator lamp is lit, the start/stop system is available and automatic engine stop is active.
If the indicator lamp is lit, the start/stop system is not available or the start/stop system has
started the engine automatically. Check whether all technical requirements have been fulfilled. If
not, ensure that all technical requirements are met ⇒ Important preconditions for automatic engine
switch-off.
The display on the instrument cluster may show the status of the start/stop system.
In addition, start/stop information on the current status of the start/stop system can be displayed as
required in Infotainment systems with a navigation function. Touch the i in the start/stop
information to obtain further information on the status.
Vehicles with a manual gearbox
•Disengage the gear and release the clutch pedal when the vehicle is coming to a stop, or when
it is stationary. The engine is stopped.
•Depress the clutch pedal to restart the engine.
Vehicles with DSG dual clutch gearbox
•To stop, press and hold the brake pedal. The engine switches off shortly before the vehicle
reaches a complete standstill or when the vehicle is stationary.
•Take your foot off the brake pedal, or depress the accelerator, to restart the engine.
Important preconditions for automatic engine switch-off
•The driver is wearing their seat belt.
•The driver door is closed.
•The bonnet is closed.
•A minimum engine temperature has been reached.
•m/k/a995MKVehicles with Climatronic: the temperature of the vehicle interior is within
the preset temperature range, and the humidity level is not too high.
•The defrost function of the air conditioning system is not switched on.
•The charge level of the 12-volt vehicle battery is sufficient.
•The temperature of the 12-volt vehicle battery is not too low or too high.
•The vehicle is not on a steep incline.
•The windscreen heating is not switched on.
•m/k/a995MKVehicles with DSG dual clutch gearbox: the steering wheel is not turned
too sharply.
•Reverse gear is not engaged.
•The Park Assist system is not active.
•The Off-road or Off-road Individual driving profile is activated.
When the conditions for automatic engine switch-off are only fulfilled when the vehicle is stationary,
the engine can also switch off subsequently, e.g. by switching off the defrost function.
Conditions for an automatic restart
The engine can start automatically under the following conditions:
•If the temperature inside the vehicle substantially increases or decreases.
•If the vehicle rolls on.
•If the electric voltage of the 12-volt vehicle battery drops.
•If the steering wheel is moved.
As a general rule, the engine always starts again automatically when required by the detected
situation and the vehicle.
