Actuate driving lights, basic function

Overview

This document contains the following information:

General

Actuate manual low beam

Actuate automatic low beam

Actuate high beam

General

Driving lights include all the light functions required for optimum illumination of the roadway:

Low beam

High beam

Daytime running lamps

Headlamp range control

Cornering light (dynamic LED headlamps)

Variable light distribution (dynamic LED headlamps)

Automatic high beam (dynamic LED headlamps)

Vehicles with LED headlamps

The front lamp units are equipped with fan motors. Operation of the fan motors provides active ventilation of the front lamp units (thermal management).

The fan motors are switched on when low beam or high beam are switched on.

Actuate manual low beam

The low beam illuminates the roadway without dazzling other road users. Low beam headlamps are operated using the exterior lights switch.

Function requirement

Circuit 15 ON

Operating principle

The exterior lighting control unit actuates the low beam in the front lamp units independently or their actuation is requested. This takes place depending on the version of the front lamp units (halogen headlamps or LED headlamps). Depending on the vehicle, the control unit for the exterior lighting is either the central signal acquisition and actuation module or the front signal acquisition and actuation module.

The activated low beam is displayed on the instrument cluster.

Vehicles with halogen headlamps

The difference in light colors for the light sources means that the standing lights are switched off when low beam is on.

The front standing lights are not switched off in the following countries:

Brazil

Georgia

Canada

Korea

Russia

Ukraine

USA

Belarus

Actuate automatic low beam

The low beam is switched on or off depending on the ambient brightness or depending on the activities of the windshield wiper system. The ambient brightness is sensed by the light sensor in the rain and light sensor. The windshield wiper system control (dependent on vehicle either the central signal acquisition and actuation module or the front signal acquisition and actuation module) provides information on its activities.

The automatic low beam is purely a comfort function and it does not relieve the driver of the need to follow the operating instructions as prescribed by the road traffic regulations.

In the event of any light sensor failure, the low beam is not deactivated until the engine is switched off.

If the windshield wiper system is active for 20 s with a wipe cycle time of less than 6 s, the low beam is switched on. If there are no wipe cycles for 60 s, the low beam is switched off. The low beam is also switched off if the wiper activities are manually canceled. The low beam remains switched on when the wiper start suppression is active. If the wiper startup suppression function is canceled, the low beam remains switched on for a further 60 s.

With automatic low beam, the low beam and the standing lights are automatically switched on and off.

Function requirements

Engine running or drivetrain operational or vehicle speed more than 3 km/h.

Exterior lights switch in "AUTO" position

Operating principle

The exterior lighting control unit actuates the low beam in the front lamp units independently or their actuation is requested. This takes place depending on the version of the front lamp units (halogen headlamps or LED headlamps). Depending on the vehicle, the control unit for the exterior lighting is either the central signal acquisition and actuation module or the front signal acquisition and actuation module.

End of trip
At the end of a trip, overlaps may occur between the automatic low beam and the headlamp switch-off delay (surround lighting).

Actuate high beam

The high beam provides sufficient wide-area illumination of the roadway .

The high beam is operated using the combination switch.

If the combination switch is pulled back and held (headlamp flashing), the high beam is switched on for a maximum of 45 s. After this, a permanently pending request is interpreted as being defective and the high beam is switched off.

Function requirements

For headlamp flasher function: Circuit 15R On

For high beams function: low beam On

Automatic high beam (dynamic LED headlamps) not active

Operating principle

The exterior lighting control unit actuates the high beam in the front lamp units independently or their actuation is requested. This takes place depending on the version of the front lamp units (halogen headlamps or LED headlamps). Depending on the vehicle, the control unit for the exterior lighting is either the central signal acquisition and actuation module or the front signal acquisition and actuation module.

The activated high beam is displayed on the instrument cluster.

ULTRA RANGE Highbeam (vehicles with dynamic LED headlamp)

In the ULTRA RANGE Highbeam, the range of the high beam is set to the legally permissible maximum. In comparison to halogen or static LED headlamps, the middle range of the light performance is improved by more than 150 meters.
