of Appendix 6 to this annex.
              3.2.1.3.2. For testing, the applicable WLTP test cycle according to paragraph 1.4.2. of this annex shall be driven.
              3.2.1.3.3. Unless stated otherwise in this appendix, the vehicle shall be tested according to the charge-sustaining Type 1 test procedure described in Annex B6.
              3.2.1.3.4. To obtain a set of applicable WLTP test cycles that are required for the determination of the correction coefficients, the test can be followed by a number of consecutive sequences required according to paragraph 2.2. of this appendix consisting of paragraph 3.2.1.1. to paragraph 3.2.1.3. inclusive of this appendix.
              3.2.2. Option 2 test sequence
              3.2.2.1. Preconditioning
              The test vehicle shall be preconditioned according to paragraph 3.3.1.1. of this annex.
              3.2.2.2. REESS adjustment
              After preconditioning, the soaking according to paragraph 3.3.1.2. of this annex shall be omitted and a break, during which the REESS is permitted to be adjusted, shall be set to a maximum duration of 60 minutes. A similar break shall be applied in advance of each test. Immediately after the end of this break, the requirements of paragraph 3.2.2.3. of this appendix shall be applied.
              Upon request of the manufacturer, an additional warm-up procedure may be conducted in advance of the REESS adjustment to ensure similar starting conditions for the correction coefficient determination. If the manufacturer requests this additional warm-up procedure, the identical warm-up procedure shall be applied repeatedly within the test sequence.
              3.2.2.3. Test procedure
              3.2.2.3.1. The driver-selectable mode for the applicable WLTP test cycle shall be selected according to paragraph 3. of Appendix 6 to this annex.
              3.2.2.3.2. For testing, the applicable WLTP test cycle according to paragraph 1.4.2. of this annex shall be driven.
              3.2.2.3.3. Unless stated otherwise in this appendix, the vehicle shall be tested according to the Type 1 test procedure described in Annex B6.
              3.2.2.3.4. To obtain a set of applicable WLTP test cycles that are required for the determination of the correction coefficients, the test can be followed by a number of consecutive sequences required according to paragraph 2.2. of this appendix consisting of paragraphs 3.2.2.2. and 3.2.2.3. of this appendix.
              4.  As an option for the manufacturer, it is allowed to apply ΔMCO2,j defined in paragraph 4.5. of Appendix 2 to Annex B6 with the following modification:

                         is the efficiency of the alternator

                       0.67 in case  is negative (corresponds to a discharge)

                       1.00 in case  is positive (corresponds to a charge)

              4.1.  In this case, the corrected charge-sustaining CO2 emission defined in paragraphs 4.1.1.3., 4.1.1.4. and 4.1.1.5. of this annex shall be replaced by ΔMCO2,j instead of .
