NOTE:If theGeneric Warning Light comes on, a
Service Fuel Filter message displays and a single chime is
heard with the ignition in the ON/RUN position or while
driving, there may there may be a problem with your
water separator wiring or sensor.
Please see your authorized dealer for service.
CAUTION!
If the “Generic Warning Lamp” remains on and a
Service Fuel Filter message displays, DO NOT
START engine before you drain the water from the
fuel filter to avoid engine damage.
Fuel Filter Replacement
Please see your authorized dealer for fuel filter replace-
ment.
Priming If The Engine Has Run Out Of Fuel
WARNING!
• Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause seri-
ous injury or death.
• Do not drain the fuel filter/water separator when
the engine is running. Fuel and fuel vapors may
escape causing as fire that can result in serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).
2. Turn the ignition to the ON/RUN position. This will activate the in-tank fuel pump for approximately 30
seconds. Repeat this process twice.

Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
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 identified on the
original factory installed hydraulic master cylinder
reservoir.
• 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

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.
We recommend you use a blend of up to 5% biodiesel, meeting ASTM
specification D-975 with your diesel engine.This vehicle is compatible with
biodiesel blends greater than 5% but no greater than 20% biodiesel meeting
ASTM specification D-7467 provided the shortened maintenance intervals
are followed as directed.
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.

MAINTENANCE SCHEDULE — DIESEL ENGINE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate in the instrument clus-
ter. This means that service is required for your vehicle.
Operating conditions such as frequent short-trips, trailer
tow, and extremely hot or cold ambient temperatures will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
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 otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 18,500 miles (29,773 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering and fill as needed
• Check function of all interior and exterior lights

Required Maintenance Intervals.
Refer to the maintenance schedules on the following
page for the required maintenance intervals.
At Every Oil Change Interval As Indicated By TheOil Change Indicator System:
•Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before your next
scheduled service.
• Inspect battery and clean and tighten terminals as
required.
At Every Oil Change Interval As Indicated By The
Oil Change Indicator System:
•Inspect brake pads, rotors, hoses and park brake.
