the manufacturer and in agreement with the technical service.
  3 Most fuel consuming mode:
   The hybrid mode which can be proven to have the highest fuel consumption of all selectable hybrid modes when tested in accordance with condition B of paragraph 4. of Annex 10 to Regulation No. 101, to be established based on information provided by the manufacturer and in agreement with the technical service.

              3.2.2. Condition A
              3.2.2.1. If the pure electric range of the vehicle is higher than one complete cycle, on the request of the manufacturer, the Type I test may be carried out in pure electric mode. In this case, engine preconditioning prescribed in paragraph 3.2.2.3.1. or 3.2.2.3.2. can be omitted.
              3.2.2.2. The procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving with the switch in pure electric position (on the test track, on a chassis dynamometer, etc.) at a steady speed of 70 per cent ±5 per cent of the maximum thirty minutes speed of the vehicle (determined according to Regulation No. 101).
           Stopping the discharge occurs:

               (a) When the vehicle is not able to run at 65 per cent of the  maximum  thirty minutes speed; or

               (b) When an indication to stop the vehicle is given to the driver by the standard on-board instrumentation; or

               (c) After covering the distance of 100 km.

                If the vehicle is not equipped with a pure electric mode, the electrical energy/power storage device discharge shall be achieved by driving the vehicle (on the test track, on a chassis dynamometer, etc.):

               (a) At a steady speed of 50 km/h until the fuel consuming engine of the  HEV starts up; or

               (b) 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

               (c) With manufacturers' 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 Table 2 (and Figure 3) of Annex 4a 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
