update flowcharts in Annex 3 in line with text.
add a footnote to the scope to exempt electrified vehicles where the internal combustion engine (ICE) operates under the test conditions
clarify the intention of paragraph 6.2.:
- that AVAS may be operational outside the specified speed ranges (e.g., in the USA where the speed range extends to 30 km/h),
- align maximum sound with UN R51.03 ASEP, and
- explicitly specify that the AVAS may function even when the ICE is running
clarify under paragraph 6.2.6. that a manufacturer may install an attenuation to enable the system to operate at different sound levels
split and clarify indoor and outdoor testing specifications under Annex 3 paragraph 2.2. to account for different needs such as a weather station
amend the flowcharts in the Annex 3 Appendix to better reflect the regulation text
align the transitional provisions in the 01 series of amendments with the format introduced following Revision 3 of the 1958 Agreement.
