General Information

Federal Law, Part 205:
Transportation Equipment Noise
Emission Controls

Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to fur-
nish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reason-
able assurance of the elimination or minimization of
noise emission degradation throughout the life of the
vehicle. In compliance with the law, the Noise Emis-
sion Control Systems maintenance located in each
applicable group within this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.

Normal Vehicle Use

The maintenance instructions contained in this
manual are based on average vehicle use and nor-
mal operating conditions. Unusual vehicle operating
conditions may require service at more frequent in-
tervals.

Recommendations for
Replacement Parts

Replacement parts used for maintenance or for the
repair of noise emission control systems should be
genuine Sterling parts. If other than genuine Sterling
parts are used for replacements or for the repair of
components affecting noise emission control, the
owner should be sure that such parts are warranted
by their manufacturer to be equivalent to genuine
Sterling parts in performance and durability.
