WARNING:Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel increases the likelihood of engine
oil dilution with fuel which may lead to major engine damage.
WARNING:Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel causes certain emission
components to malfunction which may also cause the Service Engine
Soon light to illuminate indicating an emissions-related concern.
WARNING:Do not mix diesel fuel with gasoline, gasohol or
alcohol. This could cause an explosion resulting in personal
injury.
WARNING:Do not use starting fluid such as ether or gasoline.
Such fluids can cause immediate explosive damage to the engine
and possible personal injury.
Choosing the right fuel - gasoline engines
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded
fuel or any other fuel. The use of leaded fuel is prohibited by law and
could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Note:Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
Octane recommendations - gasoline engines
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer
fuels posted as “Regular” with an
octane rating below 87, particularly
in high altitude areas. Fuels with octane levels below 87 are not
recommended.

Selective Catalytic Reduction (SCR) System - diesel engines
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF must be
maintained. Generally, the DEF tank should be filled before the DEF
gauge in the instrument cluster reached the first low level warning (refer
toDEF warning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the instrument cluster
message center and, unless the DEF tank is refilled, leads to a forced
reduction of engine operations.
DEF warning messages and vehicle operations
Your vehicle is equipped with a DEF gauge located in the instrument
cluster. The low level warning symbols (see chart) are illuminated if the
DEF gauge level drops below 0.5 gallon (1.9L) in the 5 gallon (19.0L)
DEF tank or 1 gallon (3.8L) in the 9 gallon (34.0L) DEF tank.
Upon filling the DEF tank after a low level warning, normal operation
resumes when the vehicle is restarted.
Continued driving without refilling results in the following actions as
required by the U.S. Environmental Protection Agency (EPA):

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 particulate filter. The DPF heats up to
a high temperature after only a short period of engine operation, and
can remain hot even after the engine is turned off. Failure to follow
these instructions may result in serious personal injury.
Diesel particulate filter regeneration
Under most operating conditions, DPF regeneration is transparent to the
operator. A small increase in engine/turbo sound-level is normal during
filter regeneration. If, however, your engine is operated for extended
periods of time under one of the following conditions, operator
assistance may be required to facilitate the filter regeneration process:
•Vehicle is operated in stop-and-go traffic and/or maintains low speeds
as in a city/delivery driving
•Engine is started and shut-off frequently
•Vehicle payload is relatively light
•Vehicle is regularly operated in cold ambient temperatures (i.e. below
0°F [-18°C])

The engine speed may increase slightly. To allow parked regeneration to
continue uninterrupted:
1. The vehicle must remain parked
2. The transmission must remain in P (Park) or N (Neutral) (as
previously described in Step 2).
3. The accelerator pedal, service brake pedal, and clutch pedal (if
equipped) must not be pressed
4. The parking brake must remain set
On average (depending on filter level and other factors), the process takes
20–30 minutes to complete. The DPF lamp turns off when the process is
complete. Repeat Steps 1–5, if parked regeneration is interrupted.
To discontinue parked regeneration
Press any of the floor pedals to discontinue parked regeneration.
Diesel particulate filter maintenance and service
The DPF is designed to retain a relatively large amount of residual ash
and provide many miles and hours of maintenance-free operation. At
some point, generally beyond 150,000 miles (240,000 km) or 5,000 hours
of operation (whichever comes first), the DPF requires professional
cleaning to remove the accumulated ash.
The exact number of miles or hours of operation varies greatly depending
upon vehicle/engine loading and operating conditions, ash content of the
engine oil, and quality of the diesel fuel used in your truck. Adhering to
your engine manufacturer’s recommended oil and fuel specifications
maximizes the miles and hours of operation before a DPF professional
cleaning is required. Refer to your engine manufacturer’s owner’s manual for
more details regarding recommended maintenance and service of your DPF.
Exhaust outlet assembly
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. Failure to follow these
instructions may result in serious personal injury.
The exhaust outlet assembly on your vehicle is a uniquely functioning
device that accompanies the DPF assembly. It is designed to help control
the temperature of the exhaust during the DPF regeneration process.Do
not modify or remove this device. Modification of the system

Changing wheel types
Consult your dealer or wheel/rim distributor before attempting any wheel
or fastener changes.
WARNING:Use only the same type and style wheels and
mounting hardware to replace original parts. Failure to do so
may result in an assembly that looks fine, but does not fit together
properly. This could possibly cause wheel or fastener failures which
could result in property damage, personal injury or death.
Note:Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note:Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange-nut mounting systems, changing the hub and stud assembly.

Note:Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:

All tires with Steel Carcass Plies (if equipped):
This type of tire utilizes steel cords in the sidewalls. As such, they
cannot be treated like normal light truck tires. Tire service, including
adjusting the air pressure, must be performed by personnel trained,
supervised and equipped according to Federal Occupational Safety and
Health Administration (OSHA) regulations. For example, during any
procedure involving tire inflation, the technician or individual must
utilize a remote inflation device, and ensure that all persons are clear of
the trajectory area.
WARNING:An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.
