the corresponding parameter of vehicle M.
              2.3.3. Run-in
              The vehicle shall be presented in good technical condition. It shall have been run-in and driven between 3,000 and 15,000 km before the test. The engine, transmission and vehicle shall be run-in in accordance with the manufacturer's recommendations.
              2.4. Settings
              2.4.1. Dynamometer settings and verification shall be performed according to Annex B4.
              2.4.2. Dynamometer operation
              2.4.2.1. Auxiliary devices shall be switched off or deactivated during dynamometer operation unless their operation is required by legislation (e.g. daylight running lamps).
               2.4.2.1.1. For Level 1A only
              If the vehicle is equipped with a coasting functionality, this functionality shall be deactivated either by a switch or by the vehicle's dynamometer operation mode during chassis dynamometer testing, except for tests where the coasting functionality is explicitly required by the test procedure.
              2.4.2.2. The vehicle's dynamometer operation mode, if any, shall be activated by using the manufacturer's instruction (e.g. using vehicle steering wheel buttons in a special sequence, using the manufacturer's workshop tester, removing a fuse).
              For Level 1A
              The manufacturer shall provide the responsible authority a list of the deactivated devices and/or functionalities and justification for the deactivation. The dynamometer operation mode shall be approved by the responsible authority and the use of a dynamometer operation mode shall be recorded.
              For Level 1B
              The manufacturer shall provide the responsible authority a list of the deactivated devices and justification for the deactivation. The dynamometer operation mode shall be approved by the responsible authority and the use of a dynamometer operation mode shall be recorded.
              2.4.2.3. For Level 1A
              The vehicle's dynamometer operation mode shall not activate, modulate, delay or deactivate the operation of any part (with the exclusion of the coasting functionality) that affects the emissions and fuel consumption under the test conditions. Any device that affects the operation on a chassis dynamometer shall be set to ensure a proper operation.
              For Level 1B
              The vehicle's dynamometer operation mode shall not activate, modulate, delay or deactivate the operation of any part that affects the emissions and fuel consumption under the test conditions. Any device that affects the operation on a chassis dynamometer shall be set to ensure a proper operation.
              2.4.2.4. Allocation of dynamometer type to test vehicle

              2.4.2.4.1. If the test vehicle has two powered axles, and under WLTP conditions it is partially or permanently operated with two axles being powered or recuperating energy over the applicable cycle the vehicle shall be tested on a dynamometer in 4WD operation which fulfils the specifications in paragraphs 2.2. and 2.3. of Annex B5.

              2.4.2.4.2. If the test vehicle is tested with only one powered axle, the test vehicle shall be tested on a dynamometer in 2WD operation which fulfils
