The Frontal Light Electronics includes:
- LED activation in the corresponding headlight.
- Actuation of the bulb for the turn indicator (depending on the headlight variant).

Parking Maneuver Assistant (PMA)
Parking manoeuvring assistant (PMA)
The PMA control unit performs the corresponding functions depending on equipment:
- Park Distance Control (PDC)
- Parking assist
- Parking Maneuver Assistant Plus
Park Distance Control (PDC) assists the driver when pulling in and out of a parking space.
The current distance from an obstruction is indicated by acoustic signals and on a visual display.
The Parking Maneuver Assistant performs parking in parking spaces.
In a vehicle with Parking Maneuver Assistant (PMA) all sensors of the Park Distance Control (PDC) are used. In addition, there is a sensor for the PMA in each case on the left and right of the front and rear bumper panels. For the parking assistant the camera systems of the vehicle are also required.
Lane change warning (SWW) also know as the Short Range Radar Sensor (SRR)
Lane change warning (SWW/SRR)
Both control units lane change warning SWW (primary) and SWW2 (secondary) also know as the Short Range Radar Sensor (SRR/SRR2) are shown in the picture. The SWW/SRR (primary) control unit is located on the right. The control unit lane change warning SWW2/SRR2(secondary) is on the left.
The control unit for the lane change warning (SWW/SRR) is required for the following optional equipment:
- Driving Assistant Plus (SA5AT)
The SWW/SRR is the primary control unit, and it is also used for diagnosis of the additional control units connected to the local CAN. The control unit lane change warning SWW2/SRR2 (secondary) is required for the lane change warning.
