276Phaeton - Automatic Distance Regulation (ADR)

General Description:

Adaptive Cruise Control (ACC) is a cruise control system with distance regulation that influences driving behavior with both active acceleration and deceleration.

Using Adaptive Cruise Control, any speed between 30 km/h and 200 km/h can be maintained. In addition, ACC maintains a pre-set time distance to the vehicle ahead.

With active brake intervention, the vehicle can be braked to a stop if the situation requires. System-specified thresholds are set and driver intervention is prompted with optical and acoustic warnings when necessary.

The driver assistance system is activated using the front button in the turn signal level and a selection display in the instrument cluster display. ACC is operated using the multi-function steering wheel buttons or, on vehicles without multi-function steering wheel, using the front rocker switch in the windshield wiper lever. While driving, important information is shown in the instrument cluster display.

DTC recognition and display:

Distance Regulation Control Module (J428) is equipped with On Board Diagnostics (OBD) which assists troubleshooting.

For fault finding, use one of the systems described in the " Vehicle Diagnosis, Testing and Information System" chapter in " Guided Fault Finding" function.

When first commissioning or replacing Distance Regulation Control Module (J428), initialize ADR --> [ Adaptive Cruise Control, Initializing ] Adaptive Cruise Control, Initializing.
