Engine Protection—Warning and
Shutdown Process
WARNING
When the red STOP engine or engine protection
light illuminates, most engines are programmed
to shut down automatically within 30 seconds.
The driver must immediately move the vehicle to
a safe location at the side of the road to prevent
causing a hazardous situation that could cause
bodily injury, property damage, or severe damage
to the engine.
The driver should be familiar with the vehicle warning
system, in order to bring the vehicle to a safe stop if
the engine malfunctions. If the driver doesn't under-
stand how the warning system works, an engine
shutdown could occur, causing a safety hazard.
If the engine coolant temperature, the coolant level,
the engine oil pressure, or the diesel particulate filter
for the exhaust aftertreatment system, (on some en-
gines, the engine oil temperature, or the intake air
temperature also,) reach preset levels, the engine
will begin a warning and shutdown process. See the
engine manufacturer's engine operation manual for
your vehicle, for specific details. See the "EPA07 Af-
tertreatment System" information in Chapter 7 in this
manual, for a description of the warning and shut-
down modes associated with the exhaust aftertreat-
ment system.
There are four customer-programmable levels for
electronic engine protection: OFF, WARNING, DER-
ATE, and SHUTDOWN (factory default).
In the engine monitoring OFF mode, the individual
sensor indicator lights will illuminate if a problem ex-
ists, but no shutdown action will be started, and the
event will not be recorded.
The WARNING mode warns the driver, and the en-
gine electronics will log the event for diagnostic pur-
poses. The amber Check Engine lamp will flash, and
the buzzer will sound. The amber Check Engine
lamp will go out if the problem stops. See

The DERATE and SHUTDOWN modes will reduce
the power to the engine, then shutdown the engine,
to avoid engine damage. The red Stop Engine light,
(ENG PROT or SHUT DOWN for older vehicles), will
illuminate when the problem is serious enough to
reduce the power or speed. The engine power will
ramp down, then shut down, if the problem contin-
ues.
The driver has about 30 seconds, after the red Stop
Engine light illuminates, to move the vehicle safely
off the road. If the vehicle cannot be moved to a safe
location within that time, the engine can be restarted
by turning the ignition switch to the OFF position for
at least 5 seconds, then back ON, or by pushing the
stop-engine-overide button if the vehicle is equipped
with one. This action can be repeated until the ve-
hicle is safely off the road. Do not operate the ve-
hicle until the problem has been corrected.
Warning and Indicator Lights
The dash lightbars have warning and indicator lights
that may be lettering or icons. Up until December 31,
2006, the warning and indicator lights are a mixture
of ISO icons, and lettering. Since January 2007, ISO
icons are used for all standard warning and indicator
lights on the dash lightbar. See the following table for
a full description of the icons used.
