  Responsibilities for in-service conformity
              1. The process of checking in-service conformity is illustrated in Figure 1
              2. The manufacturer shall compile all the information needed to comply with the requirements of this annex. The approval authority may also take information from surveillance programmes into consideration.
              3. The approval authority shall conduct all the procedures and tests necessary to ensure that the requirements regarding the in-service conformity are met (Phases 2 to 4).
              4. In the event of discrepancies or disagreements in the assessment of information supplied, the approval authority shall request clarification from the technical service that conducted the type approval test.
              5. The manufacturer shall establish and implement a plan of remedial measures. This plan shall be approved by the approval authority before it is implemented (Phase 5).

Appendix 6
  Requirements for vehicles that use a reagent for the exhaust after-treatment system
              1.  Introduction
                This annex sets out the requirements for vehicles that rely on the use of a reagent for the after-treatment system in order to reduce emissions.
              2.  Reagent indication
              2.1. The vehicle shall include a specific indicator on the dashboard that informs the driver of low levels of reagent in the reagent storage tank and of when the reagent tank becomes empty.
              3.  Driver warning system
              3.1. The vehicle shall include a warning system consisting of visual alarms that informs the driver when the reagent level is low, that the tank soon needs to be refilled, or the reagent is not of a quality specified by the manufacturer. The warning system may also include an audible component to alert the driver.
              3.2. The warning system shall escalate in intensity as the reagent approaches empty. It shall culminate in a driver notification that can not be easily defeated or ignored. It shall not be possible to turn off the system until the reagent has been replenished.
              3.3. The visual warning shall display a message indicating a low level of reagent. The warning shall not be the same as the warning used for the purposes of OBD or other engine maintenance. The warning shall be sufficiently clear for the driver to understand that the reagent level is low (e.g. "urea level low", "AdBlue level low", or "reagent low").
              3.4. The warning system does not initially need to be continuously activated, however the warning shall escalate so that it becomes continuous as the level of the reagent approaches the point where the driver inducement system in paragraph 8. comes into effect. An explicit warning shall be displayed
