Proposal to insert new introductory paragraphs 0. and 0.1. to 0.1.4., amend paragraph 1. – Scope, amend paragraph 1 footnote 1, insert new paragraph 2.10., amend paragraph 4.4.1. footnote 2, amend paragraph 5., and amend paragraph 5.1.4. to UN Regulation No. 121 to take into account vehicles of categories X and Y, as well as vehicles with a manual mode operating at speeds above 6 km/h equipped with an Automated Driving System.

Proposal to amend UN Regulation No. 121 by inserting new paragraph 5.2.1.1 stating that fonts shown in Table 1 are not intended to be restrictive and other fonts may be substituted if legibility is maintained. Table 1, Note No. 20 is amended to clarify that the font of letters “OFF” or “ESC OFF” is not intended to be restrictive. The purpose is to clarify the text, provide flexibility, harmonize with international standards, and adapt to current digital work tools.

The supplement accounts for vehicles of categories X and Y, and vehicles with manual mode operating above 6 km/h equipped with an Automated Driving System. Scope updated: Regulation does not apply to vehicles of category Y (no occupants inside) or category X without on-board manual mode. New definition of “Safety Concept” added. Vehicles of category X with on-board manual mode not using driver’s seat may fulfil alternative requirements if manufacturer demonstrates equivalent safety level.

Proposal to clarify the treatment of extensions of existing approvals under the new transitional provision guidelines (“Until 31 December 2019, Supplement 2 to the 01 series of amendments to this Regulation may not apply to extensions of approvals that were originally granted prior to the entry into force of Supplement 2.”)

Proposal to align the Russian text with the English version.

Proposal to correct the Russian text of the regulation.

Proposal pursuant to discussions on the application of footnote ¹⁸ under Table 1 concerning tell-tale symbols and the use of colours to convey different meanings. ISO standard 2575-2004, para. 5.1. allows for the use of different colours to convey a change in the operating condition. This proposal would remove the current footnote ¹⁸ text and application of the footnote to telltales 2, 9-12, and 19 pending a decision on the proposal to apply a revised footnote to the master lighting switch (tell-tale 1). Paragraph 5.4.1.1. of UN R121 references ISO 2575-2004 which was developed to simplify the application of UN R121 when colour changes are adopted in other UN Regulations; however, OICA submits that the footnote which references ISO 2575-2004 in relation to specific lighting devices or systems creates a degree of confusion. (If approved, this proposal would likely impact Supplement 3 to the 01 series rather than Supplement 2 given that WP.29 at its November 2017 session adopted the 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 as Supplement 2 to the 01 series.)

Proposal to apply footnote ¹⁸ to the symbol for tell-tale No. 1 (master lighting switch) in order to simplify the treatment of colour changes of tell-tales. Footnote ¹⁸ specifies "“Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.” This proposal clarifies the existing understanding of the intent of the regulation and in particular addresses concerns over interpretation where tell-tales Nos. 1 and 19 have been combined.

Proposal to insert Footnote 18 for Tell-tale 1 (Master lighting switch) stating, “Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.”

Proposal to delete footnote ¹⁸ of Table 1 regarding telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). The footnote is redundant and potentially confusing since UN R121 already refers to paragraph 5. of ISO 2575-2004 which states, “A given symbol may be shown in more than one of the colours specified in 5.1 in order to convey a change in the operating condition.”

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)).

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:

1. the term “seat belt” is replaced by “safety belt”,
2. 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
3. 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.

Proposal to clarify that footnote ¹⁸ of Table 1 applies to telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). Footnote ¹⁸ states, “Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.”

3. 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.

Proposal to clarify that in the case where telltale No. 1 (Master lighting switch) and telltale No. 19 (Position, side marker, and/or end-outline marker lamps) are combined, the symbol may be shown in other colours than specified in the table of telltales in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004 (i.e., per footnote 18 to the table).

Proposal to correct the translation into Russian of Table 1 in document GRSG/2017/5.

Proposal to align UN R121 with the 07 series of amendments to UN Regulation No. 16:

1. the term “seat belt” is replaced by “safety belt”,
2. 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
3. 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.

This proposal also aligns UN R121 with ISO 2575 per ISO Resolution 664 allowing for use of the diesel engine glow plug symbol with non-diesel technologies that (also) assist engine starting at low temperatures. The current text of the Regulation focuses on diesel engine glow plugs that assist in starting the engine at low temperatures.

At its fifty-ninth session, GRSP approved a proposal for the 07 series of amendments to UN R16 ( (GRSP/2016/2 and GRSP/59, page 24) to mandate safety belt reminders for all vehicle seats. This proposal aligns provisions in UN R121 with the changes to UN R16:
a) the term “seat belt” is replaced by “safety belt”,
b) 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
c) 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.

Paragraph 5.1.5. is modified and paragraph 5.1.7. introduced to take into consideration the strict content of GRSP/59, page 24, paragraphs 8.4.3.2.1. and 8.4.4. on safety-belt reminder for occupants of rear seat row(s). This proposal does not change any of the technical requirements of UN R121.

WP.29 adoption of the new IWVTA regulation (UN Regulation No. 0) is anticipated for March 2017 with an entry-into-force the following October. This initial regulation (00 series of amendments) will include UN Regulations as they stand prior to September 2, 2017. However, a number of these regulations contain transitional provisions such that new versions will enter into force during the 12 months following this cut-off date. Therefore, this document (updated from the earlier version) proposes a list of such regulations that would be included in the 01 series of amendments to UN R0 to be submitted for adoption by WP.29 in November 2017. In concept, UN R0 would be updated with these “upgraded” versions of the UN Regulations.
