the tank to permit it to be refuelled with the amount of fuel defined in paragraph 5.4.2. of this annex. The vehicle operation before refuelling shall include a demonstration that the vehicle is capable of exceeding 20 km/h. After re-fuelling the vehicle with the amount of fuel defined in paragraph 5.4.2. of this annex, the vehicle speed shall be limited to no more than 20 km/h.
A.1.5.4.7. If the manufacturer has opted for the "disable after parking" approach referred to in paragraph 5.4.3. of this annex, the vehicle shall be stopped after having been run for a short distance, chosen by the manufacturer, which is sufficient to demonstrate that the vehicle is capable of exceeding a speed of 20 km/h. After the vehicle has been stationary for more than one hour, the vehicle speed shall be limited to no more than 20 km/h.

                  Annex 11 ‑ Appendix 2 Description of the driver warning and inducement activation and deactivation mechanisms
A.2.1. To complement the requirements specified in this annex concerning the driver warning and inducement activation and deactivation mechanisms, this Appendix specifies the technical requirements for an implementation of those activation and deactivation mechanisms consistent with the OBD provisions of Annex 9B.
All definitions used in Annex 9B are applicable to this appendix.
A.2.2.  Activation and deactivation mechanisms of the driver warning system
A.2.2.1. The driver warning system shall be activated when the diagnostic trouble code (DTC) associated with a malfunction justifying its activation has the status defined in Table 1.
              Table 1
              Activation of the driver warning system
Failure type                           DTC status for activation of the warning system
Poor reagent quality                   Confirmed and active
Low reagent consumption                Potential (if detected after 10 hours), potential or confirmed and active otherwise
Absence of dosing                      Confirmed and active
Impeded EGR valve                      Confirmed and active
Malfunction of the monitoring system   Confirmed and active

A.2.2.1.1. If the counter associated with the relevant failure is not at zero, and is consequently indicating that the monitor has detected a situation where the malfunction may have occurred for a second or subsequent time, the driver warning system shall be activated when the DTC has the status "potential".
A.2.2.2. The driver warning system shall be deactivated when the diagnostic system concludes that the malfunction relevant to that warning is no longer present or when the information, including DTCs relative to the failures, justifying its activation is erased by a scan tool.
A.2.2.2.1. Erasing of failure information by means of a scan tool
A.2.2.2.1.1. Erasing of information, including DTCs relative to failures justifying the activation of a driver warning signal and of their associated data, by means of a scan tool shall be performed in accordance with Annex 9B.
