Driver’s Manual
Foreword
Introduction
This manual provides information needed to operate
and understand the vehicle and its components.
More detailed information is contained in the Owner’s
Warranty Information for North America booklet, and
in the vehicle’s workshop and maintenance manuals.
Custom-built Freightliner vehicles are equipped with
various chassis and cab components. Not all of the
information contained in this manual applies to every
vehicle. For details about components in your vehicle, refer to the chassis specification pages included in all new vehicles and to the vehicle specification decal, located inside the vehicle.
For your reference, keep this manual in the vehicle
at all times.
IMPORTANT: Descriptions and specifications in this
manual were in effect at the time of printing. Freightliner Trucks reserves the right to discontinue models
and to change specifications or design at any time
without notice and without incurring obligation. Descriptions and specifications contained in this publication provide no warranty, expressed or implied,
and are subject to revisions and editions without notice.
Environmental Concerns and
Recommendations
Whenever you see instructions in this manual to discard materials, you should first attempt to reclaim
and recycle them. To preserve our environment, follow appropriate environmental rules and regulations
when disposing of materials.
Event Data Recorder
This vehicle is equipped with one or more devices
that record specific vehicle data. The type and
amount of data recorded varies depending on how
the vehicle is equipped (such as the brand of engine,
if an air bag is installed, or if the vehicle features a
collision avoidance system, etc.).
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record
data in certain crash or near-crash situations, such
as air bag deployment or hitting a road obstacle, that
will assist in understanding how a vehicle’s systems
performed. The EDR is designed to record data re-
lated to vehicle dynamics and safety systems for approximately 60 seconds. This data can help provide
a better understanding of the circumstances in which
crashes and injuries occur. Data recorded includes
the following items:
•
how various systems in the vehicle were operating
•
engine system information
•
how far (if at all) the driver was depressing the
accelerator
•
if the driver was depressing the brake pedal
•
how fast the vehicle was traveling
NOTE: Data is not recorded by the EDR under
normal driving conditions. Personal data such
as name, gender, age, and crash location are
not recorded. However, other parties such as
law enforcement could combine the EDR data
with the type of personally identifying data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR is
needed. In addition to the vehicle manufacturer, other
parties that have the special equipment, such as law
enforcement, can read the information if they have
access to the vehicle or the EDR.

Tire and Rim Labels
Tire and rim labels certify suitable tire and rim combinations that can be installed on the vehicle, for the
given gross axle weight rating. Tires and rims in-
stalled on the vehicle at the time of manufacture may
have a higher load capacity than that certified by the
tire and rim label. If the tires and rims currently on
the vehicle have a lower load capacity than that
shown on the tire and rim label, then the tires and
rims determine the load limitations on each of the
axles.

immediately move the vehicle to a safe location
at the side of the road to prevent causing a hazardous situation that could cause bodily injury,
property damage, or severe damage to the engine.
See
Fig. 2.4 for an explanation of the aftertreatment
system (ATS) warning indicators, and actions required 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 derates
the engine, allowing it to run at lower rpm and slower
vehicle speed. Drive the vehicle to a safe location or
to a service facility.
IMPORTANT: Safely bring the vehicle to a stop
on the side of the road and shut down the engine as soon as the red light is seen. If the engine shuts down while the vehicle is in a hazardous 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
shuts down the engine. It first derates the engine,
then shuts 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.

Diagnostic Screens
The diagnostic screens are used by trained technicians to retrieve fault codes and other diagnostic information pertaining to the vehicle. Active faults are
current problems that require attention. If active fault
codes display during start-up or at any other time,
make a note of the fault code and text message,
then call an authorized Freightliner service facility for
assistance.
During vehicle start-up, with the parking brake set,
the ICU4 will display any active fault codes for three
seconds each until the parking brake is released. If
service cycle screens are enabled and service distance or time has been exceeded, the text SERVICE
HOUR/MI (KM) will be displayed to inform the driver
that the service interval has been exceeded and vehicle service is required. See

Gauges that sweep 270 degrees and have
pointers lit by an LED.
•
Service intervals that are programmable via the
keypad.
•
An audible warning and alert message to warn
the driver if the door is opened without first setting the parking brake.
•
A flashing alert message that appears on the
driver message center in low engine oil pressure or high coolant temperature conditions.
With the parking brake off, only the odometer and
alert screens will display. Park the vehicle and set
the parking brake to access additional screens.
The dash message center displays alert screens
when certain conditions occur. They are warnings,
cautions, or other messages that require the driver’s
attention, but not all of them are critical to the operation of the vehicle. Warning messages always display
at full brightness.
More important messages take priority over less important messages. The order of priority is:
1.
parking brake set (with the vehicle moving)
2.

Air Intake Restriction Gauge
The air intake restriction gauge indicates the vacuum
on the engine side of the air cleaner. See
On standard installations, it is mounted on the air
cleaner. As an option for easier viewing, an air intake
restriction indicator can be mounted on the auxiliary
dash panel.
NOTE: Rain or snow can wet the filter element
and cause a temporary high reading.
Air intake restriction vacuum is measured in inches
of water (inH2O). For vehicles equipped with a
graduated indicator or a restriction gauge on the
dash, check the gauge with the engine off. If the yellow signal stays locked in the red zone once the engine is shut down, or is at or above the values
shown in

Engine Oil Pressure Gauge
NOTICE
A sudden decrease or absence of oil pressure
may indicate mechanical failure. Bring the vehicle
to a safe stop and investigate the cause to prevent further damage. Do not operate the engine
until the cause has been determined and corrected.
The engine oil pressure gauge displays the current
engine oil pressure. If engine oil pressure falls below
the minimum levels shown in
engine lamp will illuminate. If the condition does not
improve, the STOP engine lamp will also illuminate
and an audible warning will sound. The engine will
then derate or shut down, depending on the type of
engine protection system installed.

Engine Oil Temperature Gauge
NOTICE
A sudden increase in oil temperature 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 engine until the cause has
been determined and corrected.
During normal operation, the optional engine oil temperature gauge should read:
•
190 to 220°F (88 to 104°C) for Caterpillar engines;
•
200 to 260°F (93 to 126°C) for Detroit and
Cummins engines
•
177 to 203°F (81 to 95°C) for Mercedes-Benz
engines
Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil temperature range for a short period are not unusual. If
the temperature returns to normal when the load decreases, there is no problem.
Fuel Gauge
The fuel gauge indicates the level of fuel in the fuel
tank(s). A single fuel gauge is standard. If equipped
with an optional second fuel tank, each fuel tank
level is indicated on a separate gauge.
Primary and Secondary Air Pressure
Gauges
WARNING
If air pressure falls below minimum pressure, the
braking ability of the vehicle will be limited. Slow
the vehicle down and bring it to a gradual stop.
Do not attempt to move the vehicle until air pressure has risen above the minimum level. Moving
a vehicle without adequate braking power could
cause an accident resulting in property damage,
personal injury, or death.
Air pressure gauges register the pressure in the primary and secondary air systems. Normal pressure,
with the engine running, is 100 to 120 psi (689 to
827 kPa) in both systems.
A low-air-pressure warning light and audible alert,
connected to both the primary and secondary systems, activate when air pressure in either system
drops below 64 to 76 psi (441 to 524 kPa).
When the engine is started, the warning light and
audible warning remain on until air pressure in both
systems exceeds minimum pressure.

Instruments and Controls Identification
Pyrometer
A pyrometer registers the exhaust temperature near
the turbocharger. Variations in engine load can cause
exhaust temperatures to vary. If the pyrometer reading shows that exhaust temperature exceeds normal,
reduce fuel to the engine until the exhaust temperature is reduced. Shift to a lower gear if the engine is
overloaded.
Speedometer
The speedometer registers speed in both miles per
hour (mph) and kilometers per hour (km/h).
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 appropriate 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 transmission fluid temperature gauge reading should not exceed 250°F (121°C).
Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil temperature range for a short period are not unusual. If
the temperature returns to normal when the load decreases, there is no problem.
NOTICE
A sudden increase in transmission fluid temperature 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.
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 battery charging problems and have them fixed before
the batteries discharge enough to create starting difficulties. Vehicles are equipped with either a voltmeter
gauge, or a digital voltmeter readout located 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 discharged battery will produce only about 11.0 volts.
If the voltmeter shows an undercharged or overcharged condition for an extended period, have the
charging system and batteries checked at an authorized 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 engine is off, the voltmeter shows only the isolated battery voltage and does not indicate the voltage of the
engine-starting batteries.
Controls
Controls and switches are listed here in alphabetical
order.
Axle Switches
Differential Lock Switch
The differential lock switch provides maximum traction for slippery conditions by forcing the wheels on
each drive axle governed by the switch to rotate together. Engagement can be at any speed, provided
the wheels are not slipping or spinning. See
Fig. 2.20.
Interaxle Lock Switch
Turbocharger Boost Pressure Gauge
A turbocharger boost pressure gauge indicates the
pressure in the intake manifold, in excess of atmospheric pressure, being created by the turbocharger.
The interaxle lock, standard on all dual-drive vehicles, is driver-actuated by means of a LOCK/
UNLOCK control valve switch. See
indicator illuminates when the interaxle lock is engaged.
