the fuel consuming engine of the HEV starts up, or

               – if a vehicle cannot reach a 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 does not start up for a defined time/distance (to be specified between technical service and manufacturer), or

            –  with manufacturer's recommendation.

          The fuel consuming engine shall be stopped within 10 seconds of it being automatically started.

         3.2.2.3. Conditioning of vehicle

         3.2.2.3.1. For compression-ignition engined vehicles the Part Two cycle described in Appendix 1 to the Annex 4 shall be used.  Three consecutive cycles shall be driven according to paragraph 3.2.2.6.3. below.

         3.2.2.3.2. Vehicles fitted with positive-ignition engines shall be preconditioned with one Part One and two Part Two driving cycles according to paragraph 3.2.2.6.3. below.

         3.2.2.4. 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, and the electrical energy/power storage device is fully charged as a result of the charging prescribed in paragraph 3.2.2.5.

         3.2.2.5. During soak, the electrical energy/power storage device shall be charged:

             (a) with the on board charger if fitted, or

             (b) with an external charger recommended by the manufacturer, using the normal overnight charging procedure.

          This procedure excludes all types of special charges that could be automatically or manually initiated like, for instance, the equalisation charges or the servicing charges.

          The manufacturer shall declare that during the test, a special charge procedure has not occurred.

         3.2.2.6. Test procedure

         3.2.2.6.1. 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.

         3.2.2.6.2. 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)).

         3.2.2.6.3. The vehicle shall be driven according to Annex 4, 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 4, Appendix 1 are not applied.  For the pattern of the operating curve the description according to paragraph 2.3.3. in Annex 4 shall apply.
