Proposal to renumber paragraph 5.8.4.2. as paragraph 5.8.4.3., insert new paragraph 5.8.4.2. requiring controls of electric side windows adjacent to the front seat row be within reach and directly accessible without multiple actions, and insert new paragraphs 5.8.8., 5.8.8.1., 5.8.8.1.1., 5.8.8.2., and 5.8.8.3. requiring electric side windows of the front seat row to still function when command is operated for at least 2 minutes in a replication of a vehicle entering water (demonstrated in accordance with a new annex). The amendment introduces provisions for ease of operation of electric side windows and guarantees front side windows operate after submergence. Laminated side windows and difficulty breaking window glass in panic situations make life hammers inappropriate alternatives to functioning windows. Research shows leaving the vehicle within one minute of water contact is important; the 2-minute requirement allows healthy margin. Paragraph 5.8.4.2. guarantees window controls operate in single action rather than requiring submenu selection.

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.

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.

Proposal to enable application to vehicles of category X, including prohibition of one-touch closing when an ADSF-2 is active, requirement for auto-reversing devices for power operated windows that can be operated by an ADSF-2, and user manual instructions for power-operated systems including warnings regarding improper use and driver and ADS responsibilities.

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.

Proposal to require the electric side windows of the front seat row to function for at least ² minutes from the time of a vehicle entering water (EDO-03-08) as amended by the EDO SIG during its 4th session.

Proposal to amend UN R21 Supplement 6 to the 01 series of amendments. The Regulation is amended to account for vehicles of category X and extend application to vehicles without driver and without manual driving controls. The scope applies to interior fittings of vehicles of category M1, including interior parts of passenger compartment, arrangement of controls, roof or opening roof, and seat-back and rear parts of seats. New definitions for “ADS feature of type 1” and “ADS feature of type 2” are inserted. Provisions for power-operated windows, roof panels and partition systems are amended, including requirements for auto-reversing devices and owner’s manual instructions.

Proposal to enable the application of the regulation to vehicles equipped with an Automated Driving System (ADS).

Proposal to enable application of UN R21 to ADS vehicles.

Proposal to enable application of UN R21 to certain vehicles equipped with an Automated Driving System.

Proposal to update references to the three-dimensional “H” point measurement and calibration procedure pursuant to the transposition of these provisions from the Consolidated Resolution on the Construction of Vehicles (RE3) to Mutual Resolution No. 1.

Revised proposal based on document GRSP/2024/7 to update references to the three-dimensional “H” point measurement and calibration procedure pursuant to moving such provisions from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1.

Proposal to update references to the three-dimensional “H” point measurement and calibration procedure pursuant to the transposition of these provisions from the Consolidated Resolution on the Construction of Vehicles (RE3) to Mutual Resolution No. 1.

Proposal to clarify rounded-edge requirements for roof-opening roof devices.

Proposal to clarify rounded-edge requirements for roof-opening roof devices.

Changes to NCAP testing oblige the use of load limiters on safety-belts with lower threshold values that yield less thorax compression but also allow for greater forward displacement of the occupants. To address the greater forward displacement of rear occupants, UN R17 is under revision to require more stringent energy dissipation performance for those areas of the rear of seats (including the head restraints and parts mounted on the seat) where the head of the rear occupant may come into contact. UN R21 allows for alternative testing of the rear parts of seats (paras. 5.7-5.7.3. ) However, in light of the changes to UN R17, this alternative approach is no longer valid. This proposal would delete the alternate method and expands the scope of UN R21 to include testing of any parts mounted on the seats.

UN Regulations 21, 26, and 125 have provisions that relate to mirrors and/or the program to enable the approval of camera-monitor systems as a replacement for conventional mirrors. This document discusses changes that will be required under the proposed CMS revisions to UN R46.
