6-6 Starting and Stopping Procedures

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.
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:
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.
