steady speed of 50 km/h without  starting up the fuel consuming engine, the speed shall be reduced               until the vehicle can run a lower steady speed where the fuel               consuming engine just does not start up for a defined time/distance               (to be specified between technical service and manufacturer);

               (c) Or with manufacturers' recommendation.

               The fuel consuming engine shall be stopped within 10 seconds of it being automatically started.
              3.1.3.3. After this preconditioning, and before testing, the vehicle shall be kept in a room in which the temperature remains relatively constant between 293 and 303 K (20 °C and 30 °C). This conditioning shall be carried out for at least six hours and continue until the engine oil temperature and coolant, if any, are within ±2 K of the temperature of the room.
              3.1.3.4. Test procedure
              3.1.3.4.1. The vehicle shall be started up by the means provided for normal use to the driver. The first cycle starts on the initiation of the vehicle start-up procedure.
              3.1.3.4.2. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and end on conclusion of the final idling period in the extra-urban cycle (Part Two, end of sampling (ES)).
              3.1.3.4.3. The vehicle shall be driven according to Annex 4a, or in case of special gear shifting strategy according to the manufacturer's instructions, as incorporated in the drivers' handbook of production vehicles and indicated by a technical gear shift instrument (for drivers information). For these vehicles the gear shifting points prescribed in Annex 4a are not applied. For the pattern of the operating curve the description according to paragraph 6.1.3.2. of Annex 4a shall apply.
              3.1.3.4.4. The exhaust gases shall be analyzed according to Annex 4a.
              3.1.3.5. The test results shall be compared to the limits prescribed in paragraph 5.3.1.4. of this Regulation and the average emission of each pollutant for Condition B shall be calculated (M2i). The test results M2i, multiplied by the appropriate deterioration and Ki factors, shall be less than the limits prescribed in paragraph 5.3.1.4. of this Regulation.
              3.1.4. Test results
              3.1.4.1. In the case of testing according to paragraph 3.1.2.5.2.1.
              . For communication, the weighted values shall be calculated as below:
               Mi = (De • M1i + Dav •. M2i )/(De + Dav)

 Where:
 Mi      =  mass emission of the pollutant i in grams per kilometre,
 M1i     =  average mass emission of the pollutant i in grams per kilometre with a  fully charged electrical energy/power storage device calculated in               paragraph 3.1.2.5.5.,
 M2i     =  average mass emission of the pollutant i in grams per kilometre with an electrical energy/power storage device in minimum state of charge (maximum discharge of capacity) calculated in paragraph 3.1.3.5.,
 De      =  vehicle
