of paragraph 6.5.3.1 and that it triggers the same consequences as those referred to in sections 6.5.3.2, 6.5.3.3 and 6.5.3.4.

          6.5.4.             Reagent control

          6.5.4.1.         For vehicles that require the use of a reagent to fulfil the requirements of this section, the driver shall be informed of the level of reagent in the on-vehicle reagent storage tank through a specific mechanical or electronic indication on the vehicle's dashboard. This shall include a warning when the level of reagent goes:

            —      below 10 % of the tank or a higher percentage at the choice of the manufacturer, or
            —      below the level corresponding to the driving distance possible with the fuel reserve level specified by the manufacturer.

          The reagent indicator shall be placed in close proximity to the fuel level indicator.

          6.5.4.2.         The driver shall be informed, according to the requirements of section 3.6.5 of Annex IV to Directive 2005/78/EC, if the reagent tank becomes empty.

          6.5.4.3.         As soon as the reagent tank becomes empty, the requirements of section 6.5.5 shall apply in addition to the requirements of section 6.5.4.2.

          6.5.4.4.         A manufacturer may choose to comply with the sections 6.5.4.5 to 6.5.4.13 as an alternative to complying with the requirements of section 6.5.3.

          6.5.4.5.         Engine systems shall include a means of determining that a fluid corresponding to the reagent characteristics declared by the manu- facturer and recorded in Annex II to this Directive is present on the vehicle.

          6.5.4.6.         If the fluid in the reagent tank does not correspond to the minimum requirements declared by the manufacturer as recorded in Annex II to this Directive the additional requirements of section 6.5.4.13 shall apply.

          6.5.4.7.         Engine systems shall include a means for determining reagent consumption and providing off-board access to consumption information.

          6.5.4.8.         Average reagent consumption and average demanded reagent consumption by the engine system either over the previous complete 48 hour period of engine operation or the period needed for a demanded reagent consumption of at least 15 litres, whichever is longer, shall be available via the serial port of the standard diagnostic connector (see section 6.8.3 of Annex IV to Directive 2005/78/EC).

          6.5.4.9.         In order to monitor reagent consumption, at least the following parameters within the engine shall be monitored:

            —      level of reagent in on-vehicle storage tank,

            —      flow of reagent or injection of reagent as close as technically possible to the point of injection into an exhaust aftertreatment system.

          6.5.4.10.      Any deviation more than 50 % in average reagent consumption and average demanded reagent consumption by the engine system over the period defined in section 6.5.4.8 shall result in application of the measures laid down in paragraph 6.5.4.13.

          6.5.4.11.      In the case of interruption in reagent dosing activity
