Vehicle Speci cation Decal
The vehicle specification decal lists the vehicle
model, identification number, and major component
models. It also recaps the major assemblies and in-
stallations shown on the chassis specification sheet.
One copy of the specification decal is attached to the
driver’s side sunvisor; another copy is inside the rear
cover of the
Owner’s Warranty Information for North
America
booklet. An illustration of the decal is shown
in Fig. 1.1.
NOTE: Labels shown in this chapter are ex-
amples only. Actual specifications may vary from
vehicle to vehicle.
Federal Motor Vehicle Safety
Standard (FMVSS) Labels
NOTE: Due to the variety of FMVSS certification
requirements, not all of the labels shown will
apply to your vehicle.
Tractors with or without fifth wheels purchased in the
U.S. are certified by means of a certification state-
ment (Fig. 1.2) and the tire and rim information, com-
bined into one label. This label is attached to the left
rear door post, as shown in Fig. 1.3.
If purchased for service in the U.S., trucks built with-
out a cargo body have an incomplete certification
label (Fig. 1.4) attached to the left rear door post. In
addition, after completion of the vehicle, a certifica-
tion label similar to that shown in Fig. 1.2 must be
attached by the final-stage manufacturer. This label
will be located on the left rear door post and certifies

that the vehicle conforms to all applicable FMVSS
regulations in effect on the date of completion.
Canadian Motor Vehicle Safety
Standard (CMVSS) Labels
In Canada, tractors with fifth wheels are certified by
means of a "Statement of Compliance" label and the
Canadian National Safety Mark (Fig. 1.5), which are
attached to the left rear door post. In addition, tire
and rim information (Fig. 1.6) is also included in the
label attached to the left rear door post.
If purchased for service in Canada, trucks built with-
out a cargo body and tractors built without a fifth
wheel are certified by a "Statement of Compliance"
label, similar to Fig. 1.2. This label must be attached
by the final-stage manufacturer after completion of
the vehicle. The label is located on the left rear door
post, and certifies that the vehicle conforms to all
applicable CMVSS regulations in effect on the date
of completion.
Tire and Rim Labels
Tire and rim labels certify suitable tire and rim combi-
nations 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.
See Fig. 1.6 for U.S. and Canadian tire and rim la-
bels.
EPA Emission Control
Vehicle Noise Emission Control Label
A vehicle noise emission control label (Fig. 1.7) is
attached either to the left side of the dashboard or to
the top-right surface of the frontwall between the
dash and the windshield.
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.
EPA07 and EPA10 Emission Control
To meet EPA07 and EPA10 emissions regulations for
vehicles domiciled in the USA or Canada, engines
manufactured after December 31, 2006 (EPA07) or
December 31, 2009 (EPA10) are equipped with an
emission aftertreatment system. Vehicles domiciled
outside of the USA and Canada may not have after-
treatment equipment, depending upon local statutory
emissions guidelines. There is a warning label
(placement will vary), for important new warning indi-
cators in the driver’s message display, that pertain to
the aftertreatment system.

Cab Door Locks and Handles
One key operates the ignition switch and all of the
door locks.
IMPORTANT: Each key is numbered. Record
the number so a duplicate key can be made, if
needed.
To unlock the driver’s door from outside the cab, in-
sert the key in the lockset and turn it one-quarter turn
clockwise (Fig. 2.1). To remove the key, turn it coun-
terclockwise to its original position. Pull out on the
door pull handle to open the door.
To unlock the passenger’s door from outside the cab,
insert the key in the lockset and turn it one-quarter
turn counterclockwise. Turn the key clockwise to the
original position to remove it.
NOTE: The cab door locks can be operated
when the doors are open.
To lock a door from outside the cab, do either one of
the following:
•Insert the key in the lockset and turn it in the
direction opposite to the unlocking direction
(counterclockwise for the driver’s door, clock-
wise for the passenger’s door). Close the door
if it is open.
•Push down the inside lock button (Fig. 2.2).
Close the door.
To open the door from the inside, lift up on the door
lever. This will unlatch the door whether or not it is
locked. If it is open, close the door by pulling the
inner door grab handle.
To lock either door from inside the cab, slide the lock
button downwards (Fig. 2.3). To unlock the door
without unlatching it, push the lock button upwards. A
red dot will show below the lock button when it is
unlocked.
Grab Handles and Access
Steps
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 one or two access
steps to provide secure footholds.

Cab Entry and Exit, Vehicles
With Two Steps
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 down from, 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.

Back-of-Cab Access
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
Vehicle Access
2.5

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.
Entering 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.
Battery Access
Battery Compartment
The battery compartment is located in the lower part
of the cab beneath and to the rear of the driver’s
door. It is fastened by a quarter-turn fastener. To
open the battery access door, turn the quarter-turn
fastener with a small screwdriver. See Fig. 2.7.

With the battery access door open (Fig. 2.8), it is
easy to get access to the battery terminals for clean-
ing, charging, or emergency jump starting.
To close the battery access door, do the following
steps:
1. Swing the battery access door to line up the
quarter-turn fastener with the hole in the cab
door frame.
2. Close the battery access door and check to be
sure the quarter-turn fastener is engaged with
the hole.
3. Turn the fastener one-quarter turn.
Cab (Battery) Isolation Switch
The cab isolation switch (see Fig. 2.9) is located on
the cab floor at the left of the driver’s seat, or inside
the battery box. The battery isolation switch reduces
the power to the cab and engine power wiring. Use it
whenever the vehicle is to be put out of service for
extended periods.
IMPORTANT: The battery disconnect switch
does not completely isolate the batteries from
the electrical system. For service operations that
require that the batteries be disconnected, al-
ways shut down the engine and remove the
negative battery cables.
NOTE: Whenever battery power is discon-
nected, clocks and electronically tuned radios
must be reset.
Hood Opening and Closing
The hood can be raised to a full-open position. A tor-
sion bar helps you to raise the hood, and to lower it
to the operating position. Hood restraint cables pre-
vent the hood from overtravel. A hood damper limits
the closing speed. In the operating position, the hood
is secured to the cab-mounted half-fenders by a
hold-down latch on each side of the hood.
To Open the Hood
1. Apply the parking brakes.
2. Release both hood hold-down latches by pulling
the ends outward. See Fig. 2.10.
CAUTION
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). Then slowly
bring it to a stop.
To Close the Hood
1. Push the hood over center.

2. As the hood goes over center, the damper auto-
matically slows its rate of descent. If needed, you
can also slow its rate of 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.
Fuse Identi cation
Main Fuse Box/PDM
The main fuse box, also known as the power distri-
bution module, or PDM, is located under the hood on
the left front fender just forward of the bulkhead mod-
ule. See Fig. 2.11. To open the fuse box, pull down
on the wire clips holding the lid on the fuse box.
A sticker inside the lid of the fuse box shows the lo-
cations of the fuses and describes the circuit(s) that
each fuse protects (see Fig. 2.12). See Table 2.1 for
descriptions of a typical set of fuses. The fuses in the
main fuse box are mini blade-type fuses. Battery
power fuses, located near the batteries, are bolt-in
megafuses.
Because the electrical system is multiplexed, no re-
lays are needed. The multiplexing module performs
the functions normally provided by relays.

Instrumentation Control Unit
The ICU3 instrument cluster is a single unit that pro-
vides the driver with engine and vehicle information.
It is comprised of gauges, warning and indicator
lamps, an audible warning, and a liquid crystal dis-
play (LCD) screen.
IMPORTANT: Vehicles that are domiciled out-
side of the U.S. and Canada may not have
EPA07- or EPA10-compliant engines with an
emission aftertreatment system (ATS), depend-
ing upon local jurisdictional emissions guide-
lines.
Figure 3.1 shows a typical ICU3 instrument cluster
installed in EPA07- and EPA10-compliant vehicles.
Vehicles that are not EPA10-compliant do not have a
fuel/diesel exhaust fluid (DEF) gauge.
There can be up to eight gauges on the driver’s in-
strument panel (six electronic and two mechanical).
The air gauges operate mechanically.
The ICU3 also has the capability to drive up to six
independent stand-alone gauges such as those in-
stalled on the auxiliary dash panel. Figure 3.2 shows
a typical dash panel layout.
Dash Message Center
The dash message center houses all of the standard
and optional warning and indicator lamps, as well as
the driver display screen. The display screen has a

7-character LCD that normally shows odometer read-
ings and, below that, a smaller 3-character LCD that
shows voltmeter readings. Warning messages and
diagnostic fault codes will also appear in the display
screen.
Information provided by the driver display screen in-
cludes:
•odometer readings (in miles or kilometers)
•trip and total engine distance
•trip and total engine hours
•service screens
•fault code displays
•warning messages
Ignition Sequence
When the ignition is turned on, the ICU3 runs
through the ignition sequence. See Fig. 3.3. First,
the ICU3 performs a self-test, looking for active fault
codes and displays them, if any, one after the other
until the engine is started or the ignition switch is
turned off. If there are no active fault codes, the
driver display screen displays the odometer.
When the ignition is first turned on, all the electronic
gauges complete a full sweep of their dials, the
warning and indicator lamps illuminate, and the au-
dible warning sounds for three seconds. On EPA10-
compliant vehicles, the DEF level indicator illumi-
nates all segments green, then turns them off one at
a time before turning the left most segment amber
then red.
