EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a 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 any person
removes or renders inoperative any
device or element of the design.
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
specifications.
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: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER -
3.5L/3.7L WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 196).
• Do not switch the ignition off when your
vehicle is moving.
• Do not use leaded fuel.
• Avoid running out of fuel.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

The automatic regeneration process is
most effective when you drive at a steady
vehicle speed of 30 mph (48 km/h) or
above for approximately 20 minutes. The
frequency and duration of the regeneration
process varies by how you drive your
vehicle, the outside air temperature and
altitude. Frequency varies between 100 mi
(160 km)
and 310 mi (500 km) and each
regeneration process lasts between 10 and
20 minutes.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
Note: During regeneration at low speed or
engine idle, you could smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to the high temperatures
reached during the regeneration process.
This is normal.
Diesel Particulate Filter Manual
Regeneration
(If Equipped) WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
Diesel particulate filter warning
lamp.
If the diesel particulate filter is
near or at saturation, the warning lamp
appears advising you to initiate diesel
particulate filter manual regeneration.
Before you start manual regeneration, do
the following:
• Park your vehicle outside of any
enclosed structure.
• Make sure the transmission is in park
(P) or neutral (N).
• Make sure the parking brake is on.
• Park your vehicle a minimum of
10 ft
(3 m) from any obstructions and
materials that can easily combust or
melt, for example, paper, leaves, fuels,
plastics and other dry organic material.
• Make sure there is a minimum of 3.2 gal
(12 L)
of fuel in the fuel tank.
• Check the engine oil level.
• Check the engine coolant level.
Manual Regeneration
Where vehicle use has significant engine
idle operation, frequent vehicle speed less
than
25 mph (40 km/h), or driving short
distances where the engine does not fully
warm up, manual regeneration allows you
to start diesel particulate filter cleaning
when the engine is idling.
