ENGINE PROTECTION SYSTEM
The engine protection will automatically derate
or stop the engine when certain engine
conditions reach a critical stage.
In the event of a serious fault, the red STOP
telltale light comes on and an audible alarm will
sound if the engine is running.
An illuminated STOP telltale light indicates a
serious problem has been detected, and the
driver must respond immediately to the problem.
The vehicle must be safely pulled off the road
and stopped. In some instances, the engine
must be switched off immediately.
AUTOMATIC ENGINE SHUTDOWN
Prior to an actual automatic shutdown, the
engine will automatically derate, go to idle, and
then stop as the vehicle speed gets below 2
mph (3 km/h).
The engine shutdown protection will
automatically derate and stop the engine when
one or more of the conditions listed below
reaches a critical point:
•
High engine coolant temperature
•
High engine oil temperature
•
Low engine oil pressure
•
High crankcase pressure (rate of change)
After the automatic engine shutdown sequence,
the engine may be restarted. To do so, turn the
ignition switch to the OFF position during 7
seconds and then turn it back to ON. However, it
will only operate for 30 seconds unless the
problem is resolved.
Use this function sparingly and in order to move
the vehicle to a safe parking place only.
Excessive use may result in severe engine
damage.
WARNING
Failure to take necessary action when the
STOP telltale light is on can ultimately result in
automatic engine derate and shutdown.
IDLE SHUTDOWN TIMER
The idle shutdown timer (optional) is
programmed to shut down the engine after a
specific engine idling time. The idling time
cannot be changed by the driver but can be
changed with the use of a laptop computer and
Premium Tech Tool. In this case, the engine
idling time can be set from 30 seconds up to 1
hour.
The engine will shut down at the set time under
the following conditions:
•
Vehicle speed is 0
•
Engine is running at normal idle speed
•
Engine coolant temperature above 120°F
(49°C)
•
Parking brake applied
•
Transmission into neutral (N)
•
Wheelchair lift system not in use
NOTE
Pressing the fuel pedal will prevent engine
shutdown and restart countdown.
JUMP STARTING
In order to avoid damage to solid-state electrical
components, it is important that jumper (booster)
cables be used correctly and only in
emergencies. To jump start, use another 24 volt
DC, negative grounded, power source. Use only
jumper cables rated at 500 cranking amperes.
