Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the DID for five seconds after a single
chime has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator systemis duty cycle based, which means the engine oil change
interval may fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to display each
time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release the
OK button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
Oil Change Reset Procedure
1. Without pushing the brake pedal, push and release the
ENGINE START/STOP button and place the ignition
to the ON/RUN position (do not start the engine).
2. Fully push the accelerator pedal, slowly, three times
within 10 seconds.

which is recommended for all operating temperatures.
This engine oil improves low temperature starting and
vehicle fuel economy.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information. The
engine oil filter should be changed at every engine oil
change.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
78 MAINTAINING YOUR VEHICLE

Component Fluid, 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.
NOTE: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.

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 me-
chanic.
•Failure to properly inspect and maintain your ve-
hicle could result in a component malfunction and
effect vehicle handling and performance. This
could cause an accident.NOTE:
•Under no circumstances should oil change intervals
exceed 8,000 miles (12 875 km) or six months, which-
ever comes first when using Biodiesel blends greater
than 5% (B5).
•The owner is required to monitor mileage for B6-B20
biodiesel, the automatic oil change indicator system
does not reflect the use of biofuels.
