to all vehicle systems with driver-selectable modes including those not solely specific to the transmission.

              1.2. The manufacturer shall provide evidence to the responsible authority concerning:

                  (a) The availability of a predominant mode under the considered conditions;

              (b) The maximum speed of the considered vehicle;

              and if required:

                  (c) The best and worst case mode identified by the evidence on the fuel consumption and, if applicable, on the CO2 emission/fuel consumption in all modes. See paragraph 2.6.6.3. of Annex B6;

              (d) The highest electric energy consuming mode;

                  (e) The cycle energy demand (according to paragraph 5 of Annex B7 where the target speed is replaced by the actual speed).

              1.3. On the basis of technical evidence provided by the manufacturer and with the agreement of the responsible authority, the dedicated driver-selectable modes, such as "mountain mode" or "maintenance mode" which are not intended for normal daily operation but only for special limited purposes, shall not be considered. Irrespective of the driver-selectable mode selected for the Type 1 test according to paragraph 2. and 3. of this appendix, the vehicle shall comply with the criteria emissions limits in all remaining driver-selectable modes used for forward driving.

              2. OVC-HEVs and OVC-FCHVs (as applicable) equipped with a driver-selectable mode under charge-depleting operating condition

              For vehicles equipped with a driver-selectable mode, the mode for the charge-depleting Type 1 test shall be selected according to the following conditions.
              The flow chart in Figure A8.App6/1 illustrates the mode selection according to this paragraph.
              2.1. If there is a predominant mode that enables the vehicle to follow the reference test cycle under charge-depleting operating condition, this mode shall be selected.
              2.2. If there is no predominant mode or if there is a predominant mode but this mode does not enable the vehicle to follow the reference test cycle under charge-depleting operating condition, the mode for the test shall be selected according to the following conditions:
                  (a) If there is only one mode which allows the vehicle to follow the reference test cycle under charge-depleting operating conditions, this mode shall be selected;
                  (b) If several modes are capable of following the reference test cycle under charge-depleting operating conditions and none of those modes is a configurable start mode, the worst case mode for electric energy consumption of those modes shall be selected;
                  (c) If several modes are capable of following the reference test cycle under charge-depleting operating conditions and at least two of those modes are a configurable start mode, the worst case mode for electric energy consumption shall be selected from these configurable start modes.
              2.3. If there is no mode according to paragraph 2.1. and paragraph 2.2. of this appendix that enables the vehicle to follow
