QUESTION	ANSWER
Is the inducement system only triggered by low levels of DEF?	NO. The inducement system ensures correct operation of the SCR/DEF system. It monitors (1) DEF level (2) DEF quality (3) Dosing hardware. A low level (1) OR a malfunction detected in area (2) or (3) will trigger the inducement system. The warning messages states the malfunction.
Is the number of engine restarts limited while the vehicle is driven with the inducement system on?	NO. The engine can be stopped/started indefinitely until the message "No Engine Restart Possible" shows.
Is there sufficient warning before the engine does NOT restart?	YES. The mileage countdown shown by the inducement system is guaranteed mileage before the no restart condition. The vehicle can be driven on the final "No Engine Restart Possible" warning until the engine is stopped by the driver. An engine stall is NOT counted as an engine stop. NOTE: Though an ECO stop is not counted as an engine stop; ECO stop functionality is NO longer available when the final "No Engine Restart Possible" warning shows.
Can the inducement system "heal" if the malfunction no longer exists?	YES. The inducement system will heal automatically - warnings will disappear - if the malfunction no longer exists. If the malfunction was to re-occur within 40 hours of operation, the inducement system will resume at the mileage it was left. This is to prevent long term tampering with the system.
Are the P2BAE/P2BAF DTC(s) to represent a malfunction?	NO. The P2BAE/P2BAF DTC(s) only help to understand at what level of inducement the vehicle currently is.
Is the low DEF level a malfunction?	NO. This is why no other DTC(s) than P2BAE/P2BAF - to represent the level of inducement the vehicle is in - are visible when low DEF occurs. The DEF tank shall be topped up with necessary volumes.
Is there a minimum top up volume when DEF level is low?	YES. More than 3 Liters DEF or 2 "KRUSE" bottles or 1 US gallon bottle are necessary to activate top up detection. This also applies when the vehicle does NOT restart because of low DEF level.
