General Information

Noise Emission Controls

Federal Law, Part 205:
Transportation Equipment Noise
Emission Controls
Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to furnish
each new vehicle with written instructions for the
proper maintenance, use, and repair of the vehicle
by the ultimate purchaser to provide reasonable as-
surance of the elimination or minimization of noise
emission degradation throughout the life of the ve-
hicle. In compliance with the law, the Noise Emission
Control Systems maintenance located in each appli-
cable group within this manual, in conjunction with
the vehicle workshop manual, provides these instruc-
tions to owners.

noise emission control systems should be genuine
Freightliner parts. If other than genuine Freightliner
parts are used for replacement or repair of compo-
nents affecting noise emission control, the owner
should be sure that such parts are warranted by their
manufacturer to be equivalent to genuine Freightliner
parts in performance and durability.
