NOTE:
Do not jump off fuses. Only jump directly off
positive post.
2. Connect the opposite end of the positive (+) jumper cable to the positive (+)post of
the booster battery.
3. Connect the negative (-)end of the jumper
cable to the negative (-)post of the
booster battery.
4. Connect the opposite end of the negative (-)jumper cable to a good engine ground
(exposed metal part of the discharged
vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts. 5. Start the engine in the vehicle that has
the booster battery, let the engine idle a
few minutes, and then start the engine in
the vehicle with the discharged battery.
CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the
fuse.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega- tive (-)jumper cable from the negative (-)
post of the booster battery.
3. Disconnect the positive (+)end of the
jumper cable from the positive (+)post of
the booster battery. 4. Disconnect the opposite end of the posi-
tive (+)jumper cable from the positive (+)
post of the vehicle with the discharged
battery.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system inspected at an authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.

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)
or 350 hours of engine run time if the vehicle
is operated in a dusty and off road environ-
ment or is operated predominately at idle or
only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
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.

NOTE:
• Under no circumstances should oil changeintervals 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 bio-
diesel, the oil change interval must not ex-
ceed 12,500 miles (20 000 km) under any
circumstances. See the Fuel Requirements
section for more information regarding opera-
tion of Chassis Cab models and Pickup mod-
els configured for use with biodiesel blend
(B6-B20) fuel meeting ASTM specification
D-7467.Perform Service Indicator —
Cummins Diesel
Your vehicle will require emissions mainte-
nance at a set interval. To help remind you
when this maintenance is due, the instru-
ment cluster will display “Perform Service”.
When the “Perform Service” message is dis-
played on the instrument cluster it is neces-
sary to have the emissions maintenance per-
formed. Emissions maintenance may include
replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clear-
ing and resetting the “Perform Service” indi-
cator message is located in the appropriate
Service Information.
