ing away.

i When you switch off the engine, Blue-
Tec
®
exhaust gas aftertreatment automat-
ically flushes the exhaust system with fresh
air. Residues of AdBlue
®
/DEF on the
metering unit or the injection nozzle might
otherwise impair the function of BlueTec
®
exhaust gas aftertreatment. Depending on
the engine's previous operating load, Blue-
Tec
®
exhaust gas aftertreatment may flush
the exhaust system several times.
When BlueTec
®
exhaust gas aftertreatment
flushes the exhaust system, an air valve is
activated. You may then hear a hissing
sound. This hissing sound does not indicate
a leak in the compressed-air system.
Continuous brake
The airbrake and the constantly open throttle
valves are employed as continuous brakes.
