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.

For the most up-to-date information visit

freightliner.com/

for the latest version of the

driver's and maintenance manuals.

Freightliner 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.

Data Logging

This vehicle is equipped with a control module that

performs data logging capabilities.

This vehicle is equipped with one or more devices

that record speciﬁc vehicle data and may perform

some of the same functionality as a regulated Event

Data Recorder but the device(s) are not subject to,

nor designed pursuant to, 49 C.F.R. Part 563.

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.).

GPS location data, fault codes, and other technical

data may be recorded.

This data may help provide a better understanding of

the circumstances of a crash.

Personal data such as name, gender, and age are

not recorded. However, other parties such as law

enforcement, could combine the data logger's

contents with the type of personally identifying data

routinely acquired during a crash investigation.

Emissions and Fuel Efficiency

Compliance

This vehicle must be regularly inspected and

maintained as indicated in the M2 Plus Maintenance

https://

Manual, and in the Pre- 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 Truck 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

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.
