Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable the application of UN R122 to ADS vehicles and to ensure that the requirements minimise the risk of burns across all vehicle occupants.

Discussion on the general idea to align the contact surface temperatures with those for M2/M3 vehicles and to introduce the possibility for manufacturers to allow for higher contact surface temperatures if it can be demonstrated that their safety concept covers for higher temperatures without increasing the risk for occupantsto get burns.

Proposal prepared by the Task Force on Automated Vehicles Regulatory Screening (TF-AVRS), with the aim to amend and supersede document ECE/TRANS/GRSG/2025/35.

Proposal to amend UN Regulation No. 122 (Heating Systems). The 01 series of amendments takes into account vehicles of categories X and Y and aligns provisions in Annex 5 for all occupants. Surface temperature limits for heating systems apply equally to drivers and passengers regardless of seat position or vehicle category, with special care for rear seats of M₁ vehicles. Manufacturers may justify higher temperatures through a safety concept demonstrating no increased burn risk. Transitional provisions allow type approvals under preceding series until 1 September 2028. The proposal amends and supersedes ECE/TRANS/GRSG/2026/7.
