When the engine is started, the warning light and
audible warning remain on until air pressure in both
systems exceeds minimum pressure.
Speedometer
Two speedometer options are available. The U.S.
version of the speedometer registers speed in both
miles per hour (mph) and kilometers per hour (km/h),
with mph in larger numbers. The metric version of
the speedometer face reverses this arrangement,
with km/h in larger numbers.
Tachometer
The tachometer indicates engine speed in revolutions
per minute (rpm) and serves as a guide for shifting
the transmission and keeping the engine in the ap-
propriate rpm range. For low idle and rated rpm, see
the engine identification plate.
Transmission Fluid Temperature
Gauge
The transmission fluid temperature gauge indicates
the transmission lubricant operating temperature.
Temperatures vary by application, but the transmis-
sion fluid temperature gauge reading should not ex-
ceed 250°F (121°C).
NOTICE
A sudden increase in transmission fluid tempera-
ture that is not caused by a load increase may
indicate mechanical failure. Bring the vehicle to a
safe stop and investigate the cause to prevent
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 indicates the
pressure in the intake manifold, in excess of atmos-
pheric 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. Cascadia vehicles are equipped with either a
voltmeter gauge, or a digital voltmeter readout lo-
cated on the bottom line of the dash message center.
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.
Driver Message Center
ICU3/ICU4
The driver message center is controlled using the
mode/reset switch, located on the right side of the
ICU, and the
+
and
–
buttons mounted in the right-
hand pod of the steering wheel (
Fig. 4.9
). See
Fig. 4.1
and
Fig. 4.9
. Tap the mode/reset switch or
the
+
switch to advance one screen; press and hold
either switch to select a menu choice or reset the
display. When the display resets, an audible chirp
sounds.
Four driving screens are accessible when the parking
brake is off. All screens and menus are accessible
when the parking brake is on (parked screens).
Driving Screens
The following screens are available when the parking
brake is off (when the vehicle is mobile) and no ac-
tive fault codes are found. Use the
+
and
–
switches
on the steering wheel, or the mode/reset switch, to
