active adaptive driving assist

Production Solution
Not applicable.
Service
Discuss the two new driver assistance systems "lane departure warning", "adaptive driving assist" with the
customer as well as the "lane center guidance of the adaptive driving assistant".
1.
Explain to the customer that:
 The lane departure warning corresponds to the Audi active lane assist with "late" steering time.
And
 The lane center guidance corresponds to the Audi active lane assist with "early" steering time.
2.
If only the Lane Departure Warning is activated, a later steering intervention takes place. This gives the
customer the feeling that the vehicle oscillates, crosses the lane or pulls to one side.
3.
Show the customer how to activate the lane center guide of the adaptive driving assistant.
