Proposal to introduce the automatic activation of the hazard warning lights upon detection of excess temperatures in the engine and/or heater compartment.

18. GRE noted that the Working Party on General Safety Provisions (GRSG), at its forthcoming session in May 2014, would consider ECE/TRANS/WP.29/GRSG/2014/3 by Germany proposing to insert into UN Regulation No. 107 (M 2 and M 3 buses) a new requirement to automatically activate hazard warning lights when excess temperature is detected in a rear engine and/or in a heater compartment. The Chair expressed his concern that this signal may be misused unnecessarily in case of heat excess not leading to fire. GRE noted that the right term should be “hazard warning signal”. Should this proposal be adopted by GRSG, UN Regulation No. 48 would have to be amended accordingly. Thus, GRE decided to await the outcome of discussion in GRSG and to revert to this issue at the next session on the basis of a proposal for amending UN Regulation No. 48 which the expert from Germany volunteered to submit.

7. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2014/3 proposing to introduce the automatic activation of the hazard warning lights upon detection of excess temperatures in the engine and/or the heater compartment. The expert from OICA stressed the need to insert transitional provisions and announced the preparation of a concrete proposal for consideration at the next session. GRSG adopted the proposal, as reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions, as draft Supplement 3 to the 05 series of amendments and as draft Supplement 2 to the 06 series of amendments to UN Regulation No. 107. GRSG underlined the need that WP.29 shall adopt these amendments together with an parallel amendments to UN Regulation No. 48 to be submitted by the Working Party on Lighting and Light-signalling (GRE). The expert from Germany volunteered to submit an official document for consideration by GRE at its October 2014 session.

Annex 3, paragraph 7.5.1.5., amend to read:

Annex 3, paragraph 7.5.6.2., amend to read:
