conditions are met simultaneously:
                  (a) The warning system has been activated with a reagent availability greater or equal to 10 per cent of the capacity of the reagent tank;
                  (b) The "continuous" warning system has been activated with a reagent availability greater or equal to the value declared by the manufacturer according to the provisions of paragraph 6. of this annex.
A.1.3.4. The demonstration of the warning system activation is deemed to be accomplished for reagent level events if, at the end of each demonstration test performed according to paragraph A.1.3.2.1., the warning system has been properly activated.
A.1.3.5. The demonstration of the warning system activation is deemed to be accomplished for DTC triggered events if, at the end of each demonstration test performed according to paragraph A.1.3.2.1., the warning system has been properly activated and the DTC for the selected failure has got the status shown in Table 1 in Appendix 2 to this annex.
A.1.4.  Demonstration of the inducement system
A.1.4.1. The demonstration of the inducement system shall be done by tests performed on an engine test bench.
A.1.4.1.1. Any additional vehicle components or sub-systems, such as ambient temperature sensors, level sensors, and driver warning and information systems, that are required in order to perform the demonstrations shall be connected to the engine system for that purpose, or shall be simulated, to the satisfaction of the Type Approval Authority.
A.1.4.1.2. If the manufacturer chooses, and subject to the agreement of the Type Approval Authority, the demonstration tests may be performed on a complete vehicle either by mounting the vehicle on a suitable test bed or by running it on a test track under controlled conditions.
A.1.4.2. The test sequence shall demonstrate the activation of the inducement system in case of lack of reagent and in case of one of the failures defined in paragraphs 7., 8., or 9. of this annex.
A.1.4.3. For the purpose of this demonstration,
                  (a) The Type Approval Authority shall select, in addition to the lack of reagent, one of the failures defined in paragraphs 7., 8. or 9. of this annex that has been previously used in the demonstration of the warning system;
                  (b) The manufacturer shall be permitted to simulate, in agreement with the Type Approval Authority, the achievement of a certain number of operating hours;
                  (c) The achievement of the torque reduction required for low-inducement may be demonstrated at the same time as the general engine performance approval process performed in accordance with this Regulation. Separate torque measurement during the inducement system demonstration is not required in this case. The speed limitation required for severe inducement shall be demonstrated in accordance with the requirements of paragraph 5. of this annex.
A.1.4.4.
