After deactivation the system shall clearly inform the driver about the system status by an acoustic emergency signal which is different from the previous acoustic warning signal, for at least five seconds or until the driver holds the steering control again.
The above requirements shall be tested in accordance with the relevant vehicle test(s) specified in Annex 8 of this Regulation.
5.6.2.2.6. Unless otherwise specified, the optical signals described in paragraph 5.6.2.2. shall all be different from each other (e.g. different symbol, colour, blinking, text).
5.6.2.3. System information data
5.6.2.3.1. Following data shall be provided together with the documentation package required in Annex 6 of this regulation to the Technical Service at the time of type approval;
5.6.2.3.1.1. The conditions under which the system can be activated and the boundaries for operation (boundary conditions). The vehicle manufacturer shall provide values for Vsmax , Vsmin and aysmax  for every speed range as mentioned in the table of paragraph 5.6.2.1.3. of this Regulation;
5.6.2.3.1.2. Information about how the system detects that the driver is holding the steering control.
