The STOP engine lamp illuminates when the engine
protection system is activated in one of two ways. On
some engines, the engine protection system derates
the engine, allowing it to run at lower rpm and slower
vehicle speed. Drive the vehicle to a safe location or
to a service facility.
IMPORTANT: Safely bring the vehicle to a stop
on the side of the road and shut down the en-
gine as soon as the red light is seen. If the en-
gine shuts down while the vehicle is in a haz-
ardous location, turn the key to the OFF position
for a few seconds, then restart the engine and
move the vehicle to a safer location.
On other engines, the engine protection system
shuts down the engine. It first derates the engine,
then shuts it down completely 30 to 60 seconds after
the indicator illuminates (depending on the critical
fault type) if the condition does not improve. Bring
the vehicle to a stop on the side of the road before
the engine shuts down.
Some vehicles may have a shutdown-override
switch, which may be used to momentarily override
the shutdown sequence. See
Chapter 7
for detailed
information regarding the shutdown process.
IMPORTANT: Do not attempt to restart the en-
gine while the vehicle is moving. Bring the ve-
hicle to a safe stop, then restart the engine.
To restart the engine, turn the ignition switch to OFF
for a few seconds, then turn the ignition switch to ON
and let the gauge sweep complete before starting the
engine. The engine will run for a short period and
shut down again if the condition does not improve.
