Instruments
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
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.

Temperature Alert
When the outside temperature drops to 34°F (1.7°C)
or less, the ICU displays a caution text at one-
second intervals for five seconds, and an audible
alert sounds. Tap the mode/reset switch to acknowl-
edge the message. The audible alert will not sound
again unless the temperature cycles above 37°F
(4°C) and back to 34°F (1.7°C) or less. This warning
only occurs while the ignition is on and the parking
brake is released.
The temperature alert message allows the driver to
enable or disable the ambient temperature warning.
Press and hold the mode/reset switch to toggle be-
tween on and off. Release the mode/reset switch,
then tap it to select the displayed choice.
Diagnostics
When the DIAG screen is displayed, press and hold
the mode/reset switch to access the various diagnos-
tic screens.
The diagnostic screens are used by trained techni-
cians to retrieve fault codes and other diagnostic in-
formation pertaining to the vehicle. If active fault
codes display during start-up or at any other time,
make a note of the fault code and take the vehicle to
an authorized Freightliner service facility
If fault codes are displayed, press and hold the
mode/reset switch to view the next fault code until
