with one Part One and two Part Two cycles of the applicable driving cycle in combination with the applicable gear shifting prescriptions as defined in paragraph 1.4. of this annex.

         4.2.3.3. 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, and the electrical energy/power storage device is fully charged as a result of the charging prescribed in paragraph 4.2.3.4. below.

         4.2.3.4. During soak, the electrical energy/power storage device shall be charged, using the normal overnight charging procedure as defined in paragraph 3.2.2.5. of this annex.

         4.2.4. Test procedure

         4.2.4.1. 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.

         4.2.4.2. The test procedures defined in either paragraph 4.2.4.2.1. or 4.2.4.2.2. may be used.

         4.2.4.2.1. 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)).

         4.2.4.2.2. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and continue over a number of repeat test cycles. It shall end on conclusion of the final idling period in the first extra-urban (Part Two) cycle during which the battery reached the minimum state of charge according to the criterion defined below (end of sampling (ES)).

          The electricity balance Q [Ah] is measured over each combined cycle, using the procedure specified in Appendix 2 to this annex, and used to determine when the battery minimum state of charge has been reached.

          The battery minimum state of charge is considered to have been reached in combined cycle N if the electricity balance measured during combined cycle N+1 is not more than a 3 per cent discharge, expressed as a percentage of the nominal capacity of the battery (in Ah) in its maximum state of charge, as declared by the manufacturer. At the manufacturer's request additional test cycles may be run and their results included in the calculations in paragraphs 4.2.4.5. and 4.4.1. provided that the electricity balance for each additional test cycle shows less discharge of the battery than over the previous cycle.

          In between each of the cycles a hot soak period of up to ten minutes is allowed. The powertrain shall be switched off during this period.

         4.2.4.3. The vehicle shall be
