6-6 Starting and Stopping Procedures
NOTE
Jumper cables must be rated at 500 cranking
amperes. If jumper cable length is 20 feet (6 m)
or less, use 2/0 (AWG) gauge wires. If cable
length is between 20 and 30 feet (6 to 9 m), use
3/0 (AWG) gauge wires.

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
l
High engine oil temperature
l
Low engine oil pressure
l
High crankcase pressure
l
After the automatic engine shutdown sequence,
the engine may be restarted. To do so, turn the
ignition switch to the OFF position for 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.
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:
Pressing the fuel pedal will prevent engine
shutdown and restart countdown.

ENGINE BLOCK HEATER

The vehicle may be equipped with an engine
immersion-type electric block heater to assist cold
weather starting. A connector is on the rear pillar
of the curbside engine compartment door frame.
Using an extension cord, connect to a 110 - 120
VAC outlet.
Connect only to a 120 VAC power source. Use
only grounded (three prongs) extension cords
with a minimum rated capacity of 15 A.
Disconnect the extension cord before starting.
Before driving, make sure the extension cord is
disconnected.
