When the red STOP engine lamp illuminates,
most engines are programmed to shut down au-
tomatically within 30 seconds. The driver must
immediately move the vehicle to a safe location
at the side of the road to prevent causing a haz-
ardous situation that could cause bodily injury,
property damage, or severe damage to the en-
gine.
See Fig. 3.3 for an explanation of the aftertreatment

Fig. 3.3, ATS Warning Lamps
The STOP engine lamp illuminates when the engine
protection system is activated in one of two ways. On
some engines, the engine protection system will der-
ate the engine, allowing it to run at lower rpm and
slower vehicle speed. Drive the vehicle to a safe lo-
cation 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.
