6.4.1.�Adaptive�distance�adjustment
A�further�innovation�is�the�adaptive�adjustment�of�the�distance�to�the�vehicle�in�front�when�ACC
is�activated.�This�distance�is�automatically�adapted�to�the�driving�situation.�Several�examples�are
provided�here:
•
The�distance�is�automatically�
reduced
�if�the�system�detects�a�dynamic�driver.�This�happens�if
the�accelerator�pedal�is�operated�frequently�when�Cruise�Control�is�active.
•
If�there�are�many�vehicles�traveling�at�a�similar�speed�in�the�adjacent�driving�lane,�there�is�a�risk
of�these�pushing�in�front�of�the�driver's�own�vehicle.�In�this�case�the�distance�is�also�slightly
reduced
.
•
If�the�function�detects�that�a�vehicle�in�front�is�being�driven�erratically,�poor�weather�or�poor
visibility,�the�distance�is�
increased
�for�safety�reasons.
The�following�rules�are�observed�when�changing�the�distance:
If�the�distance�is�set�to�distance�1�and�automatically�increases,�it�will�always�be�smaller�than�distance
2.�If�the�distance�is�set�to�level�3,�it�will�always�be�greater�than�level�2�when�reduced�automatically�with
the�maximum�adjustment.�Distance�1�is�a�special�case.�The�distance�can�only�be�increased�in�this�case
because�it�is�already�very�close�to�the�legal�minimum�distance.
To�experience�the�adaptive�distance�adjustment,�the�driver�must�activate�it�in�the�Cruise�Control�menu.
