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 Fig. 4.5 for an explanation of the aftertreatment
system (ATS) warning indicators, and actions re-
quired 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.

Common Warning and Indicator Lamps
Lamp Description
Indicates the cruise control is enabled.
NOTE: The ICU4Me does not have a green cruise control
telltale.
Indicates the high-beam headlights are on.
Table 4.1, Common Warning and Indicator Lamps
Some vehicles may have a shutdown-override
switch, which may be used to momentarily override
the shutdown sequence. See
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
Standard instruments are present on every vehicle.
They are listed here in alphabetical order to make
the information easier to find.
Optional instruments, typically located on the auxil-
iary dash panel or right-hand control panel, are not
found on every vehicle. They are listed here in alpha-
betical order, to make the information easier to find.
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. As an option for easier
viewing, the air intake restriction indicator (see
Fig. 4.6) can be mounted on the dash, usually on the
right-hand control panel.
NOTE: Rain or snow can wet the filter and
cause a temporary high reading.
Air intake restriction vacuum is measured in inches
of water (inH O). For vehicles equipped with a
