NOTE: If active faults are present, take the ve-
hicle as soon as possible to an authorized
Freightliner service facility.
If the fault is mission-critical, that is, if it is a serious
problem that requires immediate attention, the stop
engine system will activate. In most cases, the check
engine light will also illuminate.
Some examples of mission-critical faults include:
•
high coolant temperature
•
low air pressure
•
low coolant level
•
low engine oil pressure
NOTE: The check engine light does not illumi-
nate for a low air pressure fault.
The legend SERVICE ENGINE can appear on the
driver display screen as an active fault code. If this
legend appears, it means the trip miles (or hours)
have gone beyond the next required service interval,
as set by the vehicle operator.
IMPORTANT: If the legend SERVICE ENGINE
does appear on the driver display screen while
operating the vehicle, bring the vehicle to an
authorized Freightliner service facility when
convenient.
Odometer
The odometer is set to display in either miles or kilo-
meters, depending on the primary scale of the
speedometer. The legend, either MI or KM, illumi-
nates between the odometer and the volts display
when the engine is running or the headlights are
turned on.
The odometer is a seven-digit display with a decimal
point, until the vehicle has traveled 999,999.9 miles
or kilometers (km). At one million miles (km), the
odometer resets itself to 1,000,000, without the deci-
mal point, and can continue up to 9,999,999. The
odometer only displays significant figures (no leading
zeros).
Mode/Reset Switch
The mode/reset switch, shown in Fig. 3.5, is located
on the right side of the instrument cluster. The mode/
reset switch is used to scroll through the displays on
