ENGINE RUNAWAY
WARNING!
In case of engine runaway due to flammable fumes
from gasoline spills or turbocharger oil leaks being
sucked into the engine, do the following to help
avoid personal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO
2or dry chemical type fire extin-
guisher, direct the spray from the fire extinguisher
into the grille on the passenger side so that the spray
enters the engine air intake.
The inlet for the engine air intake is located behind
the passenger side headlamp and receives air
through the grille.
FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel (15
ppm Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control system. For
most year-round service, No. 2 diesel fuel meeting ASTM
specification D-975 Grade S15 will provide good perfor-
mance. If the vehicle is exposed to extreme cold (below
20°F or -7°C), or is required to operate at colder-than-
normal conditions for prolonged periods, use climatized
No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50%
No. 1 diesel fuel. This will provide better protection from
fuel gelling or wax-plugging of the fuel filters.

STARTING AND OPERATING 81

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API CJ-4 certified and
meet the requirements of Chrysler Group LLC. Use
MOPARor an equivalent oil meeting Chrysler Material
Standard MS-10902. Products meeting Cummins CES
20081 may also be used. The identification of these
engine oils are typically located on the back of the oil
container.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American Petro-
leum Institute (API). The manufac-
turer only recommends API Certified
engine oils. Oils with a high ash content may produce damaging
deposits on engine valves and/or aftertreatment system
damage. A maximum sulfated ash content of 1.00 mass %
is recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum based oil. Also, synthetic oil
must meet the same performance specifications as petro-
leum oil.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
Use SAE 15W-40 engine oil that meets Chrysler Materials
Standard MS-10902 and the API CJ-4 engine oil category.

With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also labeled on the origi-
nal factory installed hydraulic master cylinder
reservoir.(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)

Oil Change Indicator System
Ram Truck Pick-Up (2500 and 3500 Models)
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving or extended idle time can increase
the frequency of the engine oil change. This is the result
of more frequent regeneration of the exhaust after treat-
ment system, which can decrease the life of the engine oil.
Failure to change the engine oil per the maintenance
schedule can result in internal engine damage.For information on resetting the Oil Change Indicator
message, refer to “Oil Change Due” under “Electronic
Vehicle Information Center (EVIC)/EVIC Warning
Lights” in “Understanding Your Instrument Panel” for
further information.
When prompted by the Engine Oil Indicator System, the
engine oil and filter must be changed. If not prompted by
the Engine Oil Indicator System within 7,500 miles
(12 000 km) or six months since the last oil and filter
change, replace the engine oil and engine oil filter. Under
no circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes
first.
