Engine Protection System
WARNING
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 Chapter 12 for an explanation of the aftertreat-
ment system (ATS) warning indicators, and actions
required to avoid further engine protection steps.
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.
On other engines, the engine protection system will
shut down the engine. It will first derate the engine,
then shut 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 10 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 to OFF, leave
it there a few seconds, then turn the ignition to
START. The engine will run for a short period and
shut down again if the condition does not improve.
Instruments
The instruments are listed here in alphabetical order,
to make the information easier to find.
NOTE: Some of the listed instruments are op-
tional, and not found in every vehicle.
Air Intake Restriction Gauge
The air intake restriction gauge indicates the vacuum
on the engine side of the air cleaner. On standard
installations, it is mounted on the air intake duct in
the engine compartment, and has a go/no-go restric-
tion indicator without graduations. See
Fig. 3.2 . As
an option, a graduated indicator ( Fig. 3.3 ) on the air
intake duct or, for easier viewing, a dash-mounted
restriction gauge may be installed.
Air intake restriction vacuum is measured in inches
of water (inH
2
O). For vehicles equipped with a
graduated indicator or a restriction gauge on the
