further damage. Do not operate the vehicle until
the cause has been determined and corrected.
Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil tem-
perature range for a short period are not unusual. If
the temperature returns to normal when the load de-
creases, there is no problem.
Turbocharger Boost Pressure Gauge
A turbocharger boost pressure gauge ( Fig. 3.47 ) indi-
cates the pressure in the intake manifold, in excess
of atmospheric pressure, being created by the
turbocharger.
Voltmeter
The voltmeter indicates the vehicle charging system
voltage when the engine is running and the battery
voltage when the engine is off. By monitoring the
voltmeter, the driver can stay aware of potential bat-
tery charging problems and have them fixed before
the batteries discharge enough to create starting diffi-
culties.
The voltmeter will normally show approximately 13.7
to 14.1 volts when the engine is running. The voltage
of a fully charged battery is 12.7 to 12.8 volts when
the engine is off. Battery voltage under 12.0 volts is
considered a low battery, and a completely dis-
charged battery will produce only about 11.0 volts.
If the voltmeter shows an undercharged or over-
charged condition for an extended period, have the
charging system and batteries checked at an autho-
rized Freightliner service facility.
On a vehicle equipped with a battery isolator system,
the voltmeter measures the average voltage of all the
batteries when the engine is running. When the en-
gine is off, the voltmeter shows only the isolated bat-
tery voltage and does not indicate the voltage of the
engine-starting batteries.
Instrumentation Control Unit:
ICC5
The instrumentation control unit (ICU) provides the
driver with engine and vehicle information. A New
Cascadia vehicle can be equipped with either an
ICUC or ICC5. See
Fig. 3.48 for a typical ICC5
layout.
This section provides general system and operating
instructions for ICC5 components. Following sections
provide more detailed information.
ICC5
The Instrument Cluster Connect 5, or ICC5, has a
driver display screen, an infotainment touch screen,
a multimedia connection unit with two USB2 ports,
optical finger navigation control (OFN) buttons on the
steering wheel, and visual and audible warning
systems.
The driver display, or A-panel, provides the driver
with information about the vehicle status and vehicle
systems. The infotainment display, or B-panel, pro-
vides access to phone, radio, navigation, and other
controls. See "Driver Display: ICC5" in this chapter
for details on the A-panel display features. See "Info-
tainment: ICC5" in this chapter for details on the
B-panel display and multimedia connection unit.
Ignition Sequence
When the ignition is turned on, the ICU runs a self-
check. Observing the ignition sequence is a good
way to ensure the ICU is functioning properly.
IMPORTANT: Do not crank the engine until the
ICU self-check is complete.
ICC5
NOTE: There is no Lane Departure Warning
audible self-test.
When the ignition is turned on, the following actions
should occur in the ICC5:
•
The logos for the engine and transmission dis-
play on the infotainment screen.
