Noise Emissions Warranty,- Page 134

Tampering With a Noise Control
System

Federal law prohibits the following acts:
•

The removal or rendering inoperative
by any person other than for purposes
of maintenance, repair or replacement
of any device or element of design
incorporated into any new vehicle for
the purpose of noise control prior to its
sale or delivery to the ultimate
purchaser or while it is in use

•

The use of the vehicle after such device
or element of design has been removed
or rendered inoperative by any person.

The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•

Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.

•

Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer’s
specifications.

The complexity of the diesel engine makes
it so you are not encouraged to carry-out
maintenance other than the services
described in this Owner's Manual.

If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
•

A plugged or disconnected air inlet
system hose.

•

A plugged engine air filter element.

•

Water in the fuel filter and water
separator.

•

A clogged fuel filter.

•

Contaminated fuel.

•

Air in the fuel system, due to loose
connections.

•

An open or pinched sensor hose.

•

Incorrect engine oil level.

•

Incorrect fuel for climatic conditions.

•

Incorrect engine oil viscosity for
climactic conditions.

Note:

If these checks do not help you

correct the concern, have your vehicle
checked by an authorized dealer.
