Lights
Vehicle features and options
This chapter describes all standard, country-specific and optional features offered with the series. It also describes features and functions that are not necessarily available in your vehicle, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. When using these functions and systems, the applicable laws and regulations must be observed.
Lights and lighting
Switches in the vehicle
The light switch element is located next to the steering wheel.
Automatic headlight control
Principle
The low beams are switched on and off automat‐ ically depending on the ambient brightness, for example in tunnels, in twilight or if there is pre‐ cipitation.
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.
Activating
Switch position: 
The indicator light in the instrument cluster is il‐ luminated when the low beams are switched on.
System limits
The automatic headlight control cannot replace your personal judgment of lighting conditions.
For example, the sensors are unable to detect fog or hazy weather. In these situations, turn the lights on manually.
Parking lights, low beams and roadside parking lights
General information
Position of switch: 
If the driver's door is opened when the driveready state is switched off, the exterior lighting is automatically switched off after a period of time.
Parking lights
Switching on
Position of switch: 
The vehicle is illuminated on all sides.
Do not use the parking lights for extended peri‐ ods; otherwise, they might drain the battery and it would then be impossible to switch on driveready state.
Low beams
Switching on
Position of switch:
The low beams illuminate when drive-ready state is switched on.
The indicator light in the instrument clus‐ ter lights up.
Roadside parking lights
When the vehicle is parked, a one-sided roadside parking light can be switched on.
Depending on the national-market version, this function may be deactivated.
Welcome lights
Principle
The exterior lighting is switched on automatically when approaching or unlocking the vehicle.
General information
Depending on the equipment, the exterior lighting of the vehicle can be set individually.
Activating/deactivating welcome light

LED light carpet
The light source is located in the position indicated.
Keep the light source clean and unobstructed.
Pathway lighting
Principle
For the illumination of the vehicle’s surroundings after exiting the vehicle, the exterior lighting can be switched on for a defined period of time.
Switching pathway lighting on
After switching off the drive-ready state, briefly push the turn signal lever forward.
Setting the duration
- "CAR"
- "Settings"
- "Exterior lighting"
- "Pathway lighting"
- Select the desired setting.
- "OK"
Daytime driving lights
General information
Switch position:
▷
▷ Depending on the national-market version:
The daytime driving lights light up when driveready state is switched on.
Depending on the national-market version: after switching off the drive-ready state, the parking lights will illuminate in position
Activate/deactivate daytime driving lights
In some countries, daytime driving lights are mandatory, so it may not be possible to deacti‐ vate the daytime driving lights in front.
- "CAR"
- "Settings"
- "Exterior lighting"
- Depending on the national-market version: "Daytime driving lights" or "Daytime driving lights, rear
Adaptive lighting functions
Principle
Adaptive light functions enable dynamic illumina‐ tion of the road.
General information
The adaptive light functions may consist of one system or multiple systems, depending on the equipment version:
- Adaptive Light Control.
- Cornering light.
Activating
Switch position: 
The adaptive light functions are active when the drive-ready state is switched on.
Adaptive Light Control
General information
Depending on the steering angle and other pa‐ rameters, the light from the headlight follows the course of the road.
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 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 angle.
Adaptive headlight range control
The adaptive headlight range control feature bal‐ ances 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 am‐ bient lighting, for instance in towns and cities.
The high beams can be switched on and off manually at any time.
Activate Automatic High Beam Assistant
Switch position:
Press the button on the turn signal lever
The indicator light in the instrument cluster is illuminated when the low beams are switched on.
The headlights are automatically switched between low beams and high beams.
The blue indicator light in the instrument cluster lights up when the system switches on the high beams.
The Automatic High Beam Assistant is deacti‐ vated when manually switching the high beams on and off.
To reactivate the Automatic High Beam Assis‐ tant, press the button on the turn signal lever.
Deactivate Automatic High Beam Assistant
Press the button on the turn signal lever
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 sensitiv‐ ity has been modified, oncoming traffic may be momentarily blinded. There is a risk of accident. If adjustments have been made and the sensi‐ tivity has been modified, make sure that on‐ coming traffic is not momentarily blinded. Switch off the high beams manually if required.
Functional requirements
- Setting at standstill only.
- Drive readiness is switched on.
- Light is turned off.
Increase sensitivity
Push the turn signal lever to the front for approximately 10 seconds.
A Check Control message is displayed. The system responds more sensitively.
Resetting the sensitivity
Push the turn signal lever to the front again for approx. 10 seconds or switch off the drive-ready state.
The sensitivity of the Automatic High Beam Assistant is reset to the factory settings.
System limits
The Automatic High Beam Assistant cannot re‐ place the driver's personal judgment of when to use the high beams. In situation that require this, therefore dimming 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 pres‐ ence 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 in‐ creased and provides better illumination of the road.
General information
When the high beams are switched-on, starting with a speed of approx. 37 mph/60 km/h, the la‐ ser high beams in the headlight are automatically switched on in addition to the LED high beams.
Depending on the national-market version, addi‐ tional information can be taken from the laser sign on the headlight.
Safety information
The label is in the headlight and is visible from the outside.
Instrument lighting
Functional requirement
The parking lights or low beams must be switched on to set the brightness.
Setting the brightness
