Division 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 Section 8 comes into effect. An explicit warning shall be displayed (e.g. ‘fill up urea’, ‘fill up AdBlue’, or ‘fill up reagent’). The continuous warning system may be temporarily interrupted by other warning signals providing important safety related messages.
