of the corrected measured and averaged CO2 emission for vehicle M, MCO2,c,6,M according to step 6 of Table A7/1 of Annex B7, shall be verified against the linearly interpolated CO2 emission between vehicles L and H over the applicable cycle by using the corrected measured and averaged CO2 emission MCO2,c,6,H of vehicle H and MCO2,c,6,L of vehicle L, according to step 6 of Table A7/1 of Annex B7, for the linear CO2 emission interpolation.

              For Level 1B

              An additional averaging of tests using the CO2-output of step 4a is necessary (not described in Table A7/1). The linearity of the corrected measured and averaged CO2 emission for vehicle M, MCO2,c,4a,M according to step 4a of Table A7/1 of Annex B7, shall be verified against the linearly interpolated CO2 emission between vehicles L and H over the applicable cycle by using the corrected measured and averaged CO2 emission MCO2,c,4a,H values of vehicle H and MCO2,c,4a,L of vehicle L, according to step 4a used in of Table A7/1 of Annex B7, for the linear CO2 emission interpolation.

              For Level 1A and Level 1B
              The linearity criterion for vehicle M (see Figure A6/5) shall be considered fulfilled, if the CO2 emission of the vehicle M over the applicable WLTC minus the CO2 emission derived by interpolation is less than 2 g/km or 3 per cent of the interpolated value, whichever value is lower, but at least 1 g/km.

Linearity criterion for vehicle M
              If the linearity criterion is fulfilled, the CO2 values of individual vehicles shall be interpolated between vehicles L and H.
              If the linearity criterion is not fulfilled, the interpolation family shall be split into two sub-families for vehicles with a cycle energy demand between vehicles L and M, and vehicles with a cycle energy demand between vehicles M and H. In such a case, the final CO2 emissions of vehicle M shall be determined in accordance with the same process as for vehicles L or H. See step 9 in Table A7/1 of Annex B7.
              For vehicles with a cycle energy demand between that of vehicles L and M, each parameter of vehicle H necessary for the application of the interpolation method on individual values shall be substituted by the corresponding parameter of vehicle M.
              For vehicles with a cycle energy demand between that of vehicles M and H, each parameter of vehicle L necessary for the application of the interpolation method on individual values shall be substituted by 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
