OPERATING INSTRUCTIONS
Stop Engine Lamp
The stop engine warning lamp will
illuminate, and an audible tone will
sound, when a major engine problem
exists.
WARNING!
This should be considered an
emergency. You should stop the
vehicle as safely as possible and
turn OFF the ignition.
The ve-
hicle must be serviced and the
problem corrected before driving
again. Failure to comply may result
in personal injury, severe engine
damage, equipment or property
damage.
For engines with the engine-protection
shutdown feature enabled, the
stop engine lamp will begin to
flash 30 seconds before the engine
automatically shuts down. The
warning lamp alerts the operator to the
impending shutdown.
The lamp will also illuminate when the
DEF tank is almost empty or the soot
level in the DPF is at full capacity. At
this level warning, regeneration cannot
be performed and engine power will
be derated.
Engine may automatically shut down if
the check engine lamp and stop engine
lamp are illuminated and the operator
does not correct the condition.
