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 ve-
hicle, refer to the chassis specification pages in-
cluded in all new vehicles and to the vehicle specifi-
cation decal, located inside the vehicle.
For your reference, keep this manual in the vehicle

IMPORTANT: Descriptions and specifications in
this manual were in effect at the time of printing.
Freightliner Trucks reserves the right to discon-
tinue models and to change specifications or
design at any time without notice and without
incurring obligation. Descriptions and specifica-
tions contained in this publication provide no
warranty, expressed or implied, and are subject

Environmental Concerns and
Recommendations
Whenever you see instructions in this manual to dis-
card materials, you should first attempt to reclaim
and recycle them. To preserve our environment, fol-
low 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 ap-
proximately 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 oper-
ating
•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 rou-
tinely 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.
Emissions and Fuel Efficiency
Compliance
This vehicle must be regularly inspected and main-
tained as indicated in the 108SD and 114SD Mainte-
nance Manual, and in the Pre- and Post-Trip Inspec-
tions and Maintenance chapter in this manual, in
order to continue satisfactory performance and en-
sure coverage of the vehicle under the manufactur-
er’s warranty. Many maintenance procedures ensure
that the vehicle and engine continue to comply with
applicable emissions standards. Maintenance proce-
dures, using components engineered to comply with
greenhouse gas emissions and fuel efficiency regula-
tions, may be performed by an authorized Daimler
Trucks North America dealer, an independent outlet,
or the vehicle owner or operator.
The vehicle owner is responsible for determining the
suitability of replacement components to maintain

compliance with federal and local jurisdictional regu-
lations. Components including, but not limited to,
tires, cab/sleeper side extenders, chassis fairings,
bumper, hood, vehicle speed limiters, and idle reduc-
tion timers are specifically designed and manufac-
tured to exacting standards for regulatory fuel effi-
ciency and greenhouse gas emissions compliance. It
is important that these components are always re-
placed with components that meet or exceed the per-
formance of the originally installed components.

Component Information Label
NOTE: Labels shown in this chapter are ex-
amples only. Actual specifications may vary from
vehicle to vehicle.
The component information label lists the vehicle
model, identification number, and major component
models. It also lists the major assemblies and instal-
lations shown on the chassis specification sheet.
One copy of the component information label is at-
tached to the inside of the glove box; another copy is
inside the rear cover of the Owner’s Warranty Infor-
mation for North America booklet. An illustration of
the label is shown in Fig. 1.1.
Federal Motor Vehicle Safety
Standard Labels
NOTE: Due to the variety of Federal Motor Ve-
hicle Safety Standard (FMVSS) certification re-
quirements, not all of the labels shown will apply
to your vehicle.
Tractors with or without fifth wheels purchased in the
U.S. are marked as certified by means of an FMVSS
certification label. See Fig. 1.2. This label is attached
to the driver-side B-pillar, as shown in Fig. 1.3.
The tire and rim portion of the FMVSS certification
label certifies suitable tire and rim combinations that
can be installed on the vehicle, for the given gross
axle weight rating. Tires and rims installed 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.
Trucks built without a cargo body that are intended
for service in the U.S. have an incomplete vehicle
certification label attached by the final-stage manu-
facturer. See Fig. 1.4. This label will be attached to
the incomplete vehicle document included with the
vehicle, and certifies that the vehicle conforms to all
applicable FMVSS regulations in effect on the date of
completion.
Canadian Motor Vehicle Safety
Standard Labels
In Canada, tractors with fifth wheels are marked as
certified by means of a statement of compliance label
with the Canadian National Safety Mark attached to
the driver-side door frame B-pillar. See Fig. 1.5.
Trucks built without a cargo body and tractors built
without a fifth wheel that are intended for service in
Canada have an incomplete vehicle certification label
attached to the driver-side B-pillar. After completion
of the vehicle, a complete certification label must be
attached by the final-stage manufacturer to certify
that the vehicle conforms to all applicable Canada
Motor Vehicle Safety Standard (CMVSS) regulations
in effect on the date of completion.
Component GWR Label
The component GWR label is located on the
passenger-side B-pillar. The label provides maximum
GWR ratings for each component.
See Fig. 1.6 for a typical component GWR label.
Emissions Labels
Aftertreatment System Indicators
Label
Engines and vehicles manufactured after December
31, 2006 and domiciled in the U.S. or Canada are
required to meet all EPA regulations effective as of
the vehicle build date, and are equipped with an
emission aftertreatment system (ATS). Vehicles do-
miciled outside of the U.S. and Canada may not
have aftertreatment equipment, depending upon local
statutory emissions guidelines. See Table 1.1.

A warning label on the driver-side visor contains im-
portant warning indicators in the instrument cluster
that pertain to the ATS. See Fig. 1.7.
It is a violation of U.S. federal law to alter exhaust
plumbing, ATS, or other components in any way that
would bring the engine/vehicle out of compliance with
certification requirements [Ref: 42 U.S.C. S7522(a)
(3)]. It is the owner’s responsibility to maintain the
vehicle so that it conforms to EPA regulations.
EPA Noise Emission Control Label
A vehicle noise emission control label (Fig. 1.8)is
located on the driver-side B-pillar as shown in
Fig. 1.3. It is the owner’s responsibility to maintain
the vehicle so that it conforms to EPA regulations.
IMPORTANT: Certain Freightliner incomplete
vehicles may be produced with incomplete noise
control hardware. Such vehicles will not have a
vehicle noise emission control information label.
For such vehicles, it is the final-stage manufac-
turer’s responsibility to complete the vehicle in
conformity to U.S. EPA regulations (40 CFR Part
205) and label it for compliance.

Cab Entry and Exit
For ease of entry and exit, there are three grab
handles, one on the A-pillar, one on the inner B-pillar,
and an optional one on the inside of the door. In ad-
dition, the steering wheel may be used to provide
secure handholds. There are at least two access
steps to provide secure footholds.
NOTE: The A-pillar grab handle is not installed
on the driver’s side.
The grab handles, access steps, and steering wheel
are all part of the cab access system. Use these
"helping hands" when getting into, or out of, the cab.
They will increase your security and comfort.

Back-of-Cab Access
WARNING
External surfaces of the exhaust system remain
hot after the engine has been shut down. When
accessing the back of the cab or sleeper, do not
touch any part of the exhaust system, or severe
burns could occur.
When trailer air and electrical connections cannot be
reached conveniently from the ground, Federal Motor
Carrier Safety Regulations require commercial carri-
ers to provide back-of-cab access.
Optional grab handles are mounted on each cab
sidewall, or on the left sidewall only. See Fig. 2.6.
Steps are mounted either on the fuel tank(s) or on
metal brackets. When a deck plate is necessary, it is
mounted across the top of the frame rails.
IMPORTANT: Climb onto, and down from, back-
of-cab access facing in toward the vehicle, as
you would on a ladder. Do not climb up or down
facing out away from the vehicle.
WARNING
Wet or dirty shoe soles greatly increase the
chance of slipping or falling. If your soles are wet
or dirty, be especially careful when climbing
onto, or leaving, the back-of-cab area.
Always maintain three-point contact with the
back-of-cab access supports while entering and
exiting the back-of-cab area. Three-point contact
means both feet and one hand, or both hands
and one foot, on the grab handles, steps, and
deck plates. Other areas are not meant to sup-
port back-of-cab access, and grabbing or step-
ping in the wrong place could lead to a fall, and
personal injury.
Be careful not to get hands or feet tangled in
hoses or other back-of-cab equipment. Careless-
ness could cause a person to trip and fall, with
possible injury.
Climbing Up to Back-of-Cab
When climbing onto the deck plate, do the following:
1. Grasp the sidewall grab handle with both hands.
Reach up as far as is comfortable.
2. Place one foot on the bottom step and pull your-
self up.
3. Place your other foot on the top step.
4. Move your lower hand to a higher position on the
grab handle.
5. Step onto the deck plate.
Climbing Down from Back-of-Cab
To climb down from the back-of-cab area:
1. Grasp the sidewall grab handle with both hands.
2. Step one foot at a time onto the top step.
3. Move your upper hand to a lower position on the
grab handle.
4. Move one foot to the bottom step.

5. Move your upper hand to a lower position on the
grab handle.
6. Step to the ground with your upper foot first.
Hood Opening and Closing
The hood can be raised to a full-open position. A
strut helps you to raise the hood, and to lower it to
the operating position. Hood restraint cables prevent
the hood from overtravel. The hood strut limits the
closing speed. In the operating position, the hood is
secured to the cab-mounted cowl by a hold-down
latch on each side of the hood.
To Tilt the Hood
1. Apply the parking brakes.
2. Release both hood hold-down latches by pulling
the ends outward. See Fig. 2.7.
NOTICE
Do not let the hood free-fall to the full-open posi-
tion. To do so could cause damage to the hood
or hood straps.
3. Standing in front of the hood, raise the rear of
the hood upward until it reaches the over-center
position (45 degrees from vertical). See Fig. 2.8.
Then slowly bring it to a stop.
To Return the Hood
1. Push the hood over center.
2. As the hood goes over center, the strut automati-
cally slows its rate of descent. If needed, you
can also slow its descent with your hand.
3. Make sure the hood is flush with the cowl, then
secure the hood by engaging both hood hold-
down latches.
IMPORTANT: Make sure that both hold-down
latches are fully engaged before operating the
vehicle.

Vehicle Power Distribution
WARNING
Do not attempt to modify, add, splice, or remove
electrical wiring on this vehicle. Doing so could
damage the electrical system and result in a fire
that could cause serious personal injury or prop-
erty damage.
Power Distribution Modules
The main power distribution module (PDM) is located
under the hood on the driver-side splash shield. See
Fig. 3.1. The PDM contains the circuit breakers and
fuses required to protect the vehicle cab circuits. The
label on the inside of the PDM cover identifies typical
set of fuses.
The powertrain PDM (PTPDM) is mounted in the en-
gine compartment near the main PDM. See Fig. 3.1.
It controls power to the engine, aftertreatment system
(ATS), transmission, and other powertrain-related
circuits.
The auxiliary PDM is located on the cab back wall,
behind the driver’s seat. See Fig. 3.2. The auxiliary
PDM may contain the auxiliary powernet distribution
box, the body lighting PDM, and the trailer PDM, if
so equipped.
Main Powernet Distribution Box
The main powernet distribution box (PNDB) is
mounted on the cab frontwall next to the bulkhead
module. See Fig. 3.1. It supplies power to the
PTPDM and main PDM, and powers other vehicle
functions, including the clock. The label on the PNDB
fuse cover identifies typical circuits.
An auxiliary PNDB may also be located on the cab
back wall, behind the driver’s seat.
Load Disconnect Switch
WARNING
Turning the load disconnect switch to the OFF
position does not disconnect the connection be-
tween the battery and the starter. To work on the
vehicle safely, the negative leads must be discon-
nected from the battery.
The optional load disconnect switch (Fig. 3.3)is
used to avoid excessive draw on the battery when
the vehicle is parked for an extended period of time.
When the load disconnect switch is set to OFF, it sig-
nals the PNDB to disconnect battery power to pow-
ertrain and accessory loads.
The load disconnect switch is mounted in one of two
locations:
•inside the cab on the left side of the driver’s
seat;
•on/near the battery box;
IMPORTANT: The ignition should be turned OFF
before using the load disconnect switch.

Battery Access
The batteries on a standard vehicle are located on
the driver’s side, behind the fuel tank. See Fig. 3.4.
To access the batteries, pull the cotter pin from the
latch on the battery box cover, then release the latch
and lift off the cover.

Instrumentation Control Unit
The instrumentation control unit (ICU) provides the
driver with engine and vehicle information. It is com-
prised of standard and optional gauges, an audible
warning, a driver message center, and a lightbar con-
taining warning and indicator lamps (also known as
telltales). Warning and indicator lamps illuminate in
red (danger), amber (caution), green (status advi-
sory), or blue (high-beam headlights active).
Figure 4.1 shows a typical ICU3 instrument cluster.
The following headings in this chapter provide addi-
tional information and operating instructions for ICU
components:
•"Warning and Indicator Lights"
•"Instruments"
•"Driver Message Center"
Ignition Sequence
When the ignition is turned on, the ICU runs a self-
check. See Fig. 4.2. 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.
When the ignition is turned on, the following actions
should occur:
