Noise Control System Required Maintenance &
Warranty
All vehicles built over 10,000 lbs. (4 535 kg) Gross Vehicle
Weight Rating and manufactured for sale and use in the
United States are required to comply with the Federal
Government’s Exterior Noise Regulations. These vehicles
can be identified by the Noise Emission Control Label
located in the operator’s compartment.
Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every six months or 7,500 miles (12 000 km) whichever
comes first, to assure proper operation of the noise controlsystems. In addition, inspection and service should be
performed anytime a malfunction is observed or sus-
pected. Proper maintenance of the entire vehicle will help
the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts should
be tight and in good condition. Damaged components,
burned or blown out mufflers, burned or rusted out
exhaust pipes should be replaced according to the proce-
dures and specifications outlined in the appropriate service
manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned and
that the cover is tight. Check all hoses leading to the air
cleaner for tightness. The air filter element must also be
clean and serviced according to the instructions outlined in
the Maintenance Schedule section of this manual.Tampering With Noise Control System Prohibited
Federal law prohibits the following acts or the causing
thereof: (1) the removal or rendering inoperative by any
person, other than for purposes of maintenance, repair, or

ComponentFluid, Lubricant, or Genuine Part
Fuel Selection 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 performance.
If climatized or diesel Number 1 ULSD fuel is not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions, Mopar Premium Diesel Fuel Treatment (or equiva-
lent) is recommended to avoid gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.Pickup models, and Chassis Cab models configured with optional B20
capability, are additionally compatible with 20% biodiesel meeting ASTM specification D-7467.
Diesel Exhaust Fluid MOPAR Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO 22241 may result in system
damage. You can receive assistance in locating DEF in the United States by calling 866-RAM-
INFO (866-726-4636). In Canada call 1–800–465–2001 (English) or 1–800–387–9983 (French).

MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes after a fully
warmed engine is shut off. Checking the oil level while the
vehicle is on level ground will improve the accuracy of the
oil level reading. Add oil only when the level is at or below
the ADD or MIN mark.
Once A Month
• Inspect the batteries, and clean and tighten the terminals
as required.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter. •
Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime a
malfunction is observed or suspected. Retain all receipts.
Oil Change Indicator System — Cummins Diesel
Your vehicle is equipped with an engine oil change indi-
cator system. This system will alert you when it is time to
change your engine oil by displaying the words “Oil
Change Due” in your instrument cluster display. The oil
change reminder will remind the owner to change the
engine oil every 15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab models and Pickup
models configured with optional B20 capability that are
using B20 biodiesel, which are 12,500 miles or 400 hours,
whichever comes first. Failure to change the engine oil per
the maintenance schedule can result in internal engine
damage.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
210 MAINTENANCE SCHEDULE

referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.
Replace the engine oil and oil filter every 15,000 miles (24
000 km) or six months, or sooner if prompted by the oil
change indicator system. Under no circumstances should
oil change intervals exceed 15,000 miles (24 000 km) or six
months, whichever comes first.
NOTE:
•Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or
500 Hours, whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab Only).
If Chassis Cab models and Pickup models configured with
optional B20 capability are operated with greater than 5%
levels of biodiesel, the oil change interval must not exceed
12,500 miles (20 000 km) under any circumstances. See the
Fuel Requirements section for more information regarding
operation of Chassis Cab models and Pickup models
configured for use with biodiesel blend (B6-B20) fuel
meeting ASTM specification D-7467.Perform Service Indicator — Cummins Diesel
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is due,
the instrument cluster will display “Perform Service”.
When the “Perform Service” message is displayed on the
instrument cluster it is necessary to have the emissions
maintenance performed. Emissions maintenance may in-
clude replacing the Closed Crankcase Ventilation (CCV)
filter element. The procedure for clearing and resetting the
“Perform Service” indicator message is located in the
appropriate Service Information.

Inspection and service should also be performed anytime a
malfunction is observed or suspected. Retain all receipts.
* Inspect the front and rear axle surfaces every 20,000 miles
(32,000 km). If gear oil leakage is suspected, check the fluid
level. If using your vehicle for police, taxi, fleet, off-road or
frequent trailer towing change the axle fluid every
20,000 miles (32,000 km).
** Under no circumstances should oil change intervals
exceed 15,000 miles (24 000 km) or six months or
500 Hours, whichever comes first.
*** The manufacturer highly recommends that all cooling
system service, maintenance, and repairs be performed by
your local authorized dealer.
**** Under no circumstances should the air cleaner filter
element exceed 30,000 miles (48,000 km) or 24 months,
whichever comes first.WARNING!
•You can be badly injured working on or around a
motor vehicle. Do only service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a
service job, take your vehicle to a competent
mechanic.
• Failure to properly inspect and maintain your vehicle
could result in a component malfunction and effect
vehicle handling and performance. This could cause
an accident.
CAUTION!
***The manufacturer highly recommends that all
cooling system service, maintenance, and repairs be
performed by your local authorized dealer.
