UN R21 requires the owner’s manual to contain clear instructions for power-operated window/roof panel/partition systems, including explanation of possible consequences, use of driver-controlled switches, and WARNING messages indicating dangers to children and requiring special care with remote closing systems. UN R173 references to Annex 9, paragraph 3 are unnecessary as this paragraph no longer exists in R173 but is now in UN R16 S10 Annex. UN R94 Annex 3 requires a line break.

The 25th session of the GRSP Task Force on Automated Vehicles Regulatory Screening (AVRS) was held online on 28 April 2026. The Task Force discussed regulatory frameworks for Y-category vehicles, including mass compatibility and crash test exceptions, and reviewed UN Regulation 127 on pedestrian protection for Y-category vehicles. The Task Force also addressed UN Regulation 12 feedback and identified minor mistakes in three proposals: ECE/TRANS/WP.29/2026/63, ECE/TRANS/WP.29/2026/65, and ECE/TRANS/WP.29/2026/71, which require corrections before submission to WP.29.
