Lights and lighting
Overview
Buttons in the vehicle
Functions via iDrive
Buttons on the vehicle key
Automatic headlight control
Principle
The low beams are switched on and off automatically depending on the ambient brightness, for example in tunnels, in twilight or if there is precipitation.
General information
A blue sky with the sun low on the horizon can cause the lights to be turned on. If the low beams are switched on manually, the automatic headlight control is deactivated.
Activate automatic headlight control
Press the button on the light switch element.
The LED in the button lights up.
The indicator light in the instrument cluster is illuminated when the low beams are switched on.

▷ Adaptive Light Control.
▷ Cornering light.
Activating the adaptive lighting functions
- Press the button on the light switch element.
The LED in the button lights up.
The adaptive lighting functions are active when the drive-ready state is switched on.
Adaptive Light Control
General information
Depending on the steering-wheel angle and other parameters, the light from the headlight follows the course of the road.
To avoid blinding oncoming traffic, the Adaptive Light Control does not swivel to the opposite lane when the vehicle is at a standstill.
Cornering light
Principle
In tight curves, for instance on mountainous roads or when turning, an additional cornering light is switched on that lights up the inside of the curve when the vehicle is moving below a certain speed.
General information
The cornering light is automatically switched on depending on the steering-wheel angle or, where applicable, the use of turn signals. When driving in reverse, the cornering lights may be automatically switched on regardless of the steering-wheel angle.
Adaptive headlight range control
The adaptive headlight range control feature balances out acceleration and braking processes as well as the vehicle load conditions in order to avoid blinding oncoming traffic.
Automatic High Beam Assistant
Principle
The Automatic High Beam Assistant detects other road users early on and automatically switches the high beams on or off depending on the traffic situation.
General information
The Automatic High Beam Assistant ensures that the high beams are switched on, whenever the traffic situation allows. In the low speed range, the high beams are not switched on by the system.
The system responds to light from oncoming traffic and traffic driving ahead of you, and to ambient lighting, for instance in towns and cities.
The high beams can be switched on and off manually at any time.
Functional requirements
▷ Automatic headlight control is activated.
▷ Low beams are switched on.
Activating Automatic High Beam Assistant
- "MENU"
- "Vehicle apps"
- "Exterior lighting"
- "Additional settings"

The blue indicator light in the instrument cluster lights up when the system switches on the high beams.
Interruption of the journey with activated Automatic High Beam Assistant: the Automatic High Beam Assistant remains activated when continuing the journey.
The Automatic High Beam Assistant is deactivated when manually switching the high beams on and off.
To reactivate the Automatic High Beam Assistant, press the turn signal lever up, arrow 1.
Deactivating Automatic High Beam Assistant
Press the turn signal lever forward, arrow 1, or pull the turn signal lever backward when the high beams are switched on, arrow 2.
When the Automatic High Beam Assistant is deactivated via iDrive, the operation with the turn signal lever is not possible.
Sensitivity of the Automatic High Beam Assistant
General information
The sensitivity of the Automatic High Beam Assistant can be adjusted.
Safety information
Warning
If adjustments have been made or the sensitivity has been modified, oncoming traffic may be momentarily blinded. There is a risk of accident. If adjustments have been made and the sensitivity has been modified, make sure that oncoming traffic is not momentarily blinded. Switch off the high beams manually if required.
Functional requirements
▷ Setting at standstill only.
▷ Drive-ready state is switched on.
▷ Light is turned off.
Increasing sensitivity
Push the turn signal lever to the front for approximately 10 seconds.

Resetting the sensitivity
Push the turn signal lever to the front again for approx. 10 seconds or switch off the driveready state.
The sensitivity of the Automatic High Beam Assistant is reset to the factory settings.
System limits
The Automatic High Beam Assistant cannot replace the driver's personal judgment of when to use the high beams. In situations that require this, therefore dim manually.
The system is not fully functional in the following situations, and driver intervention may be necessary:
- In very unfavorable weather conditions, such as fog or heavy precipitation.
- When detecting poorly-lit road users such as pedestrians, cyclists, horseback riders and wagons; when driving close to train or ship traffic; or at animal crossings.
- In tight curves, on hilltops or in depressions, in crossing traffic or half-obscured oncoming traffic on highways.
- In poorly-lit towns and cities or in the presence of highly reflective signs.
- When the windshield in front of the interior mirror is fogged up, dirty or covered with stickers, etc.
Laser high beams
Principle
The headlight range of the high beams is increased and provides better illumination of the road.
General information
The laser high beams are integrated into the headlights and emit from there. When the high beams are turned on, starting with a speed of approx. 37 mph/60 km/h, the laser high beams are automatically turned on in addition to the LED high beams.
Depending on the national-market version, additional information can be taken from the laser sign on the headlight.
Safety information
The respective info label is located in or on the headlight and is visible from the outside or when the hood is open.
