The headlamp units are primarily made of plastic and make use of free-form reflectors in order to optimize light distribution.

The transparent plastic cover is made from polycarbonate, which is coated for protection against scratches and cracks.

In the event of damage to the cover the entire headlamp unit needs to be replaced.

The headlamp unit also houses the turn signal lamp and the main beam headlamp.

The manual headlamp leveling control is activated via an electric motor which is controlled via a rotary regulator in the light switch.

The headlamp leveling positioning motor cannot be replaced by itself. If necessary, it needs to be replaced together with the complete headlamp unit.

For conventional headlamps, adapting the vehicle to conform to country-specific traffic situations (left/right-hand side traffic) during travel is accomplished by affixing punched adhesive strips to specific areas of the headlamp.

All conventional headlamps use 12 V bulbs with a spiral-wound filament.

Vehicles with conventional lighting can be optionally equipped with adaptive front lighting. In this case the dipped beam headlamps are implemented with a projection lens. The system is not compatible with automatic headlamp inclination and only works when the lights are switched on.

When the dipped beam headlamps are in use only the projection headlamp is active. In full beam mode the full beam headlamps and the dipped beam headlamps are used.

While cornering, the dipped beam projectors swivel toward the inside of the bend, whereby the maximum attainable correction angles are 9° for the projector on the outside of the bend and 14° for the projector on the inside of the bend.

When reverse is engaged, adaptive front lighting is disabled. When reverse gear is disengaged again and the vehicle moves at a speed above 3 km/h, the adaptive front lighting follows the relevant steering movements.

During parking maneuvers at speeds of less than 3 km/h the adaptive front lighting does is not activated in order to prevent dazzling oncoming traffic when the steering wheel is being turned from one side to the other.

The adaptive front lighting actuator motors are stepper motors.

The headlamp leveling positioning motor cannot be replaced by itself. If necessary, it needs to be replaced together with the complete headlamp unit.

The headlamp leveling system motors are DC motors.

Before performing the headlamp alignment, check the steering with the aid of the Worldwide Diagnosis System (WDS). To do this, the headlamp leveling must be set to "0" and the steering wheel must be in the "0" position (+/- 3°).

System error

In the event of any system error(s) in the adaptive front lighting actuating motors the error message "Advanced Front Light Failure" is displayed on the driver information display in the instrument cluster. In the event of a headlamp leveling motor fault, both headlamps are moved to the central position by means of the adaptive front lighting actuator motors and they remain in this position. In the event of an adaptive front lighting actuator motor fault, the headlamp leveling motor moves the relevant headlamp to the lowest position where it remains. The intact headlamp is moved to the "0" position by the adaptive front lighting actuator motor.

The adaptive front headlamps can be adapted to different traffic requirements in different countries (e.g. driving on the left/right) by applying pre-cut adhesive template strips to specific areas of the headlamps.

WARNING:
WARNING:High voltages of up to 30 kV are present in the system. Ensure that the headlamp assembly electrical connector is disconnected if the headlamp assembly is removed.

High intensity discharge headlamps are optionally available.

A single Xenon gas discharge lamp in the center projector is used for both the dipped beam and main beam headlamps.

In main beam mode the 15° aperture required for dipped beam operation is pushed out from the light beam by a positioning motor, as a result of which the full light beam of the gas discharge lamp becomes available.

An additional reflector with a conventional filament bulb is available for main beam operation. This bulb is also switched when the headlamp flashers are used.

The headlamp leveling positioning motor cannot be replaced by itself. If necessary, it needs to be replaced together with the complete headlamp unit.

The gas discharge headlamps can be adapted to different traffic requirements in different countries (e.g. driving on the left/right) by applying pre-cut adhesive template strips to specific areas of the headlamps.

Headlamp leveling system

An automatic headlamp leveling system is a legal requirement for vehicles with gas discharge headlamps.

The automatic headlamp leveling system is a second-generation dynamic system which provides additional benefits for the driver in terms of improved illumination of the road due to improved control over the headlamp beam.

In a static system, the vehicle is only considered as a stationary object, whereas a dynamic system also takes into account the dynamic changes to the inclination of the vehicle owing to load changes whilst driving.

The system is designed to respond to changes in the inclination of the vehicle caused by the long-term effects of aerodynamic forces acting on the vehicle (e.g. due to continuous driving at high speeds).

In order to prevent unnecessary changes in the height of the headlamp beam, the system filters out surface irregularities and any pitching of the vehicle under braking and acceleration.

    The following components are part of the headlamp leveling system:

  • Control module
  • Actuator motors for headlamp leveling
  • Headlamp leveling sensors on the front and rear axles

Front headlamp leveling sensor

Rear headlamp leveling sensor

The front and rear sensors are Hall sensors, which transmit an analog signal to the control module.

Accordingly, the system needs to be set up with WDS after any components are replaced or any other repairs are carried out.

Adaptive front light

On vehicles with projection headlamps with dynamic adaptive front lighting or with gas discharge headlamps, an additional cornering light system is provided which is located in the inner part of the headlamp unit.

The cornering lights are switched on depending on the vehicle speed (up to 80 km/h max.) in conjunction with the steering angle (approx. 30° with the vehicle stationary). As a requirement for this, either the dipped beam headlamps or the main beam headlamps need to be switched on.

During cornering only the cornering light on the inside of the bend is switched on to improve illumination of the bend.

Automatic headlamps

    The low beam headlamps and side lamps are switched on automatically if all of the following conditions are satisfied:

  • Ignition switch in the "II" or "III" position
  • Light switch in the "AUTO" position
  • Detected ambient light conditions below a stored threshold value

The dipped beam headlamps and the side lights are switched on or off by the generic electronic module (GEM) depending on the input signals of the combined rain sensor/light sensor.

Ambient light sensor

The combined rain sensor/light sensor is attached to the windshield, near the interior rear view mirror.

The ambient light sensor determines the general light intensity.

For this purpose, it detects the light over as wide an angle as possible, without taking the direction of incidence into account.

The front light sensor determines the light intensity directly in front of the vehicle.

If both the ambient light sensor and the front light sensor detect a sudden reduction in light intensity at the same time, then an algorithm-based calculation is used to determine the fact that the vehicle has entered a tunnel.

In this type of case a request to switch on the exterior lights and the display lamps in the instrument cluster is transmitted to the GEM.

The tail lamps are divided into two parts and differ both in terms of installation and the bulbs between SAV and LMV versions.

Backup lamps

On the SAV version, the backup lamps are automatically switched off by the GEM after 10 minutes, if the vehicle is not moving. This is intended as an overheating protection for the tail lamps.

Stoplamp

The additional high-mounted stoplamp is mounted in the middle of the tailgate above the rear window and also incorporates the washer nozzle for the rear window. A W16W glass base bulb is used.

The stoplamps are switched on via the stoplamp switch on the brake pedal as soon as the brake pedal is actuated.

On vehicles with an electronic parking brake or adaptive speed control system the stoplamps are additionally actuated via the CAN bus.

Parking lamps

The parking lamps are switched on for the relevant side of the vehicle via the turn signal lever when the ignition switch is in position "0". In addition, there is also a parking lights function on the light switch which can be used to switch on all side lights.

The light switch has been modified and now includes electronic controls. The light switch is connected to the GEM via the LIN bus.

After switching the ignition off and back on again the front fog lamps and the rear fog lamp are deactivated. They then need to be switched back on again if they are required.

Lamp failure detection

Failure of the following lighting components is indicated to the driver via the display in the instrument panel:

  • Dipped beam headlamps
  • Stop lamp
  • Rear fog lamp
  • Trailer turn signal lamp (only in trailer mode; controlled by the trailer module)
  • Trailer stoplamp (only in trailer mode; controlled by the trailer module)

The indicator lamp in the instrument cluster flashes at twice the normal frequency to indicate failure of the turn signal lamp.

Malfunction of the bulb control module on vehicles with adaptive front lighting is indicated via the display in the instrument cluster.
