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

Model All (4xWD) 

Model All (CAR) 

Overview 

This document contains information on:

General 

Distance control regulates the distance from a preceding vehicle as specified by the driver. Distance control may experience functional restrictions as a result of various factors associated with this operation.

Function 

System functions impaired 

Distance control may be impaired or may not function as expected in the following situations, for example, due to the system functions:

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

Obstacles and stationary vehicles 

Distance control cannot react to obstacles or stationary vehicles that are not detected by the sensor system. In certain circumstances, the system will not respond adequately or at all if, for example, the vehicle in front turns off and there is a stationary vehicle or other obstacle in front of it.

Bends, curved entrances and exits 

On bends, distance control may detect vehicles only to a limited extent. The subject vehicle may then brake unexpectedly or too late.

Vehicles crossing in front of the subject vehicle 

Distance control may erroneously detect vehicles crossing. If distance control is activated, the vehicle may drive off unintentionally (such as at an intersection with cross traffic).

Lane change by other vehicles 

Vehicles changing lanes within the regulated distance may cause distance control to brake unexpectedly.

Driving off the normal line 

In certain circumstances, distance control may not detect vehicles driving offset to the side. The distance to the vehicle in front will become too short.

Narrow vehicles 

In this case, distance control will not detect the vehicle in front at one side of the lane because it is too narrow. The distance to the vehicle in front will become too short.
