15. GRSP resumed consideration on a proposal tabled by the expert from Germany (ECE/TRANS/WP.29/GRSP/2014/13), aimed at ensuring that no vehicle occupants would be unintentionally fully locked inside the vehicle. The expert from OICA, in cooperation with the expert from France, introduced GRSP-55-10-Rev.3 on allowing occupants to manually activate, from the interior of the vehicle, an acoustic warning in case the ignition is switched off. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2014/13, as amended by Annex II to the GRSP 55th session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their November 2014 sessions as draft 04 series of amendments to the UN Regulation.
