Functional Limitations Of Distance Control, Detailed Information - GF30.30-D-0024-01A

Model All (Light transporter) 

Overview 

This document contains information on:

General 

Distance control regulates the distance to the vehicle in front as specified by the driver. In this connection, distance control may be functionally restricted due to a range of factors.

Function 

System functions impaired 

Due to the system functions, distance control may be impaired or not function in the expected manner e.g. in the following situations:

The system may not respond or may respond only in a limited manner in the following cases:

Obstacles and stationary vehicles 

Distance control cannot respond to obstacles or stationary vehicles that are not detected by the sensor system. The system might not respond adequately or at all if, for example, the vehicle in front is turning off and there is a stationary obstacle or vehicle in front of it.

Bends, curved entrances and exits 

Distance control can detect vehicles on bends only to a limited extent. Your own vehicle may then brake unexpectedly or too late.

Vehicles crossing in front of own vehicle 

Distance control may detect crossing vehicles by mistake. If distance control is active, the vehicle may drive off unintentionally (e.g. at an intersection with cross traffic).

Lane change by other vehicles 

Vehicles that change lanes at the regulated distance may trigger an unexpected braking procedure by the distance monitoring system.

Offset driving 

Distance control may not always detect vehicles driving offset to the side. The distance to the vehicle in front becomes too small.

Narrow vehicles 

Distance control fails to detect the vehicle in front on the edge of the road due to its small width. The distance to the vehicle in front becomes too small.
