Function
Turn assist is explained using a left turn-off situation in
right-hand traffic. Right Adaptive Cruise Control Sensor
G259, Control Module for Adaptive Cruise Control J428 and
Laser Distance Regulation Control Module J1122 continu-
ously monitor the traffic in front of one's own vehicle. The
front camera and the laser scanner send the data they have
acquired to J428.
The ACC control module merges the data and instructs
other systems to initiate actions appropriate to the situa-
tion. The merging of data from various sources provides a
very exact map of the vehicle periphery.

Installation location
To implement Audi pre sense turn assist, the vehicle
requires:
› Right Adaptive Cruise Control Sensor G259 and Control
Module for Adaptive Cruise Control J428.
› Driver Assistance Systems Front Camera R242.
› Laser Distance Regulation Control Module J1122.
Switching turn assist off and on
When Audi pre sense is off, turn assist is also off. In addi-
tion, turn assist can be switched off separately in the MMI
menu. If turn assist is switched off separately, it stays off
until the function is reactivated in the MMI. Switching the
ignition off and on does not activate turn assist if it has
been switched off separately.
