Proposal to specify “The odometer shall display the distance in the unit corresponding to that of the predominant speedometer scale. If a setting makes it possible for the driver to select the odometer display distance in km or miles independently of the speedometer, the odometer shall identify the unit used.”

Proposal to require the odometer to display distance unit (i.e., km or miles) and a minimum number of integer numerals.

Proposal by the experts from France, United Kingdom of Great Britain and Northern Ireland, the International Motorcycle Manufacturers Association (IMMA) and the International Organization of Motor Vehicle Manufacturers (OICA) to remove the categories M1 and N1 from the scope of the regulation to avoid duplication with UN Regulations Nos. 94, 95 and 153.

Amendment to include the unit of odometer measurement in the display to resolve concerns over dual-mode systems.

An alternative proposal to that by ECE/TRANS/WP.29/GRSG/2021/7

Proposal for odometer display and units

Proposal for clarifying the intention of the amendments proposed by France per document GRSG/2021/7

UN R39 allows for odometer units in miles. This proposal would clarify requirements for systems that can switch the odometer units between kilometers and miles to ensure that only one unit of measurement for total distance is used at a time.
