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 related 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.

Emissions and Fuel Efficiency Compliance

This vehicle must be regularly inspected and maintained as indicated in the Business Class M2 Mainte-

nance Manual, and in the Pretrip and Post-Trip Inspections and Maintenance chapter in this manual, in

order to continue satisfactory performance and ensure coverage of the vehicle under the manufacturer’s warranty. Many maintenance procedures ensure that the vehicle and engine continue to comply with applicable emissions standards. Maintenance procedures, using components engineered to comply with greenhouse gas emissions and fuel efficiency regulations, 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

STI-455-6 (11/14)

Foreword

compliance with federal and local jurisdictional regulations. Components including, but not limited to, tires, cab/sleeper side extenders, chassis fairings, bumper, hood, vehicle speed limiters, and idle reduction timers are speciﬁcally designed and manufactured to exacting standards for regulatory fuel efficiency and greenhouse gas emissions compliance. It is important that these components are always replaced with components that meet or exceed the performance of the originally installed components.

Fig. 1.1, Component Information Label

Federal Motor Vehicle Safety Standard Labels

NOTE: Due to the variety of Federal Motor Vehicle Safety Standard (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 marked as certiﬁed by means of an FMVSS certiﬁcation label. See to the driver-side B-pillar, as shown in

Fig. 1.2. This label is attached

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 manufacturer. See 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.

Fig. 1.4. This label will be attached to

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

If purchased for service in Canada, trucks built without a cargo body and tractors built without a ﬁfth wheel are marked as certiﬁed by a "Statement of Compliance" label, similar to Fig. 1.4. This 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.

f080117

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 domiciled outside of the U.S. and Canada may not have aftertreatment equipment, depending upon local statutory emissions guidelines. See

A warning label on the driver-side visor contains important warning indicators in the instrument cluster that pertain to the ATS. See

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.

Hood Opening and Closing

The hood can be raised to a full-open position. A torsion bar helps you to raise the hood, and to lower it to the operating position. Hood restraint cables prevent 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

Apply the parking brakes.

Release both hood hold-down latches by pulling the ends outward. See

Fig. 2.10.

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, always shut down the engine and remove the negative battery cables.

2.7

CAUTION

Do not let the hood free-fall to the full-open position. To do so could cause damage to the hood or hood straps.

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

Push the hood over center.

Fuse Identiﬁcation

Main Fuse Box/PDM

The main fuse box, also known as the power distribution module, or PDM, is located under the hood on the left front fender just forward of the bulkhead module. See on the wire clips holding the lid on the fuse box.

A sticker inside the lid of the fuse box shows the locations of the fuses and describes the circuit(s) that each fuse protects (see 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 relays are needed. The multiplexing module performs the functions normally provided by relays.

Instrumentation Control Unit

The instrumentation control unit (ICU) provides the driver with engine and vehicle information. It is comprised of standard and optional gauges, an audible warning, a driver message center, and a lightbar containing warning and indicator lamps (also known as telltales). Warning and indicator lamps illuminate in red (danger), amber (caution), green (status advisory), or blue (high-beam headlights active).

The following headings in this chapter provide additional information and operating instructions for ICU components:

•

"Driver Message Center"

Figure 3.1 shows a typical ICU3 instrument cluster.

Ignition Sequence

When the ignition is turned on, the ICU runs a selfcheck. See 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:

Table 3.1 to determine if the lamp illumi-

nated indicates a problem requiring service.

If the ICU receives active fault codes, it displays them one after the other until the parking brake is released or the ignition is turned off. Once the parking brake is completely released, the ICU displays the odometer. If there are no active faults, the ICU displays the odometer after the self-check completes.

NOTE: If active faults are present, take the vehicle to an authorized Freightliner service facility as soon as possible.

Audible Alerts

An audible alert sounds during the ignition sequence and whenever one of the following conditions exists:

•

Engine oil pressure falls below the minimum preset value.

•

Coolant temperature rises above the maximum preset value.

•

Air pressure falls below about 70 psi (483 kPa).

•

Parking brake is set with the vehicle moving faster than two miles per hour.
