NOTE:
With electronic shift transfer case:
• Steps 2 through 4 are requirements thatmust be met before pushing the NEUTRAL
(N) button, and must continue to be met
until the shift has been completed. If any of
these requirements are not met before
pushing the NEUTRAL (N) button or are no
longer met during the shift, the NEUTRAL
(N) indicator light will flash continuously
until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition must be in the ON/RUN mode for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indicator
lights will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have
not been met.Shifting Out Of NEUTRAL (N)

transfer case will shift to the position
indicated by the selector switch. • With electronic shift transfer case with
push-button selector switch, push and
hold the switch for the desired transfer
case position, until the NEUTRAL (N)
indicator light turns off and the desired
position indicator light turns on.

SCHEDULED SERVICING — GASOLINE
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.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe Op-
erating 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 pos-
sible, 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 other than
your authorized dealer, the message can bereset by referring to the steps described under
“Warning And Indicator Lights” or “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
Manual at
www.mopar.com/en-us/care/
owner-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for further information.
Gasoline Engines:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers.
Severe Duty:
Change Engine Oil at 4,000 miles
(6,500 km) or 350 hours of engine run time
if the vehicle is operated in a dusty and off
road environment or is operated predomi-
nately at idle or very low engine RPM’s. This
type of vehicle use is considered Severe Duty. 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 reser- voir, brake master cylinder, power steering
and automatic transmission, and fill as
needed
• Check function of all interior and exterior lights

Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km)

SCHEDULED MAINTENANCE — 6.7L
CUMMINS DIESEL ENGINE
CAUTION!
Failure to perform the required mainte-
nance 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 reser- voir, 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.
• Inspect front end, and lubricate — If equipped with serviceable fittings.
• Lube the front drive shaft fitting (4X4 mod- els only).
Inspection and service should also be per-
formed 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 indicator 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 dis-
play. 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 mod-
els and Pickup models configured with op-
tional B20 capability that are using B20 bio-
diesel, 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.
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.
