the reagent is approaching a very low proportion of the capacity of the reagent tank and the point where the driver inducement system will come into effect is approached. It shall culminate in a driver notification at a level that is at the choice of the manufacturer, but is sufficiently more noticeable than the point where the driver inducement system in paragraph 6.3. comes into effect.
6.2.4. The continuous warning shall not be easily disabled or ignored. When the warning system includes a message display system, an explicit message shall be displayed (for example. "fill up urea", "fill up AdBlue", or "fill up reagent"). The continuous warning may be temporarily interrupted by other warning signals providing important safety related messages.
6.2.5. It shall not be possible to turn off the driver warning system until the reagent has been replenished to a level not requiring its activation.
6.3. Activation of the driver inducement system
6.3.1. The low-level inducement system described in paragraph 5.3. shall be enabled, and subsequently activated according to the requirements of that section, if the reagent tank level goes below 2.5 per cent of its nominally full capacity or a higher percentage at the choice of the manufacturer.
6.3.2. The severe inducement system described in paragraph 5.4. shall be enabled, and subsequently activated according to the requirements of that section, if the reagent tank is empty (that is, the dosing system is unable to draw further reagent from the tank) or at any level below 2.5 per cent of its nominally full capacity at the discretion of the manufacturer.
6.3.3. It shall not be possible to turn off the low-level or severe driver inducement system until the reagent has been replenished to a level not requiring their respective activation.
7.  Reagent quality monitoring
7.1. The vehicle shall include a means of determining the presence of an incorrect reagent on board a vehicle.
              7.1.1. The manufacturer shall specify a value CDmin, which is greater than the highest reagent concentration that results in tailpipe emissions exceeding the limit values specified in paragraph 5.3. of this Regulation.

              7.1.1.1. During the phase-in period specified in paragraph 4.10.7. of this Regulation and upon request of the manufacturer for the purpose of paragraph 7.1.1. the reference to the NOx emission limit specified in paragraph 5.3. to this Regulation shall be replaced by the value of 900 mg/kWh.

7.1.1.2. The value of CDmin shall be demonstrated during type approval by the procedure defined in Appendix 6 to this annex and recorded in the extended documentation package as specified in paragraph 5.1.4. to this Regulation.
7.1.2. Any reagent concentration lower than CDmin shall be detected and be regarded, for the purpose of paragraph 7.1., as being
