Proposal to amend paragraph 4.4.3. to add a letter “X” preceding the approval number when ACSF of Category A, B1 or C are exempted from technical requirements or when the steering system exhibits ACSF of Category B2, D or E functionality, to require vehicles equipped with ACSF of Category A to fulfil requirements unless equipped with a DCAS complying with UN Regulation No. 171, and to require deactivation of RCP systems based on driver position detection through a simple and obvious action.
