Proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)” and to align UN R121 with the 07 series of amendments to UN Regulation No. 16: - the term “seat belt” is replaced by “safety belt”,
- the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote 18 has been added to item 21, and
- this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote 22 is added to item 21.
In addition, paragraph 5.1.5. is modified and paragraph 5.1.7. introduced to take into consideration the content of GRSP/59, page 24, regarding paragraphs 8.4.3.2.1. and 8.4.4. on safety-belt reminders for occupants of rear seat row(s). This proposal does not change any of the technical requirements of UN R121.

Proposal from the WP.29 Secretariat for additional corrections to the table of tell-tales, concerning items 31 (Combustion
pre-heat; engine start aid) and 32 (Choke (cold starting device)).
