inducement. Once in level 3 inducement, the
operator can perform a key cycle and the engine will
enter Safe Harbor Mode. Safe Harbor Mode can only
be implemented up to three times.

Reduced Performance
When the ECM is configured to "Reduced
Performance" and the DEF level is below 1%, the
engine will be in level 2 inducement. The check
engine lamp and emissions malfunction indicator
lamp will illuminate and flash slowly. The DEF level
gauge amber lamp will remain lit. The engine will
have a 50% derate. When the DEF tank has been
emptied of all DEF, the engine will have a 100%
derate. An empty DEF tank also limits the engine to
1000 rpm or low idle, whichever is greater. No further
inducement action will occur for "Reduced
Performance" configuration. Safe Harbor Mode is
allowed for three key cycles.
