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 com-
petent 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.
Severe Duty Conditions
(****) Change the engine oil and engine oil
filter at every 3,000 miles (5 000 km) or
3 months if using your vehicle under any of
the following severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — 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
servicing.
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 will influence
when the “Oil Change Required” message is
displayed.
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 un-
der “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further
information.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the
housing when the new filter is installed if the
residual oil is not either removed from the
housing or enough time has not elapsed to
allow the oil to drain back into the engine.
When servicing the oil filter on this engine,
carefully remove the filter and use a suction
gun to remove any residual oil left in the
housing or wait about 30 minutes for the oil
to drain back into the engine.
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter-
vals that are required to keep your vehicle
operating properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal-
ership know your vehicle best, and have ac-
cess to factory trained information, genuine
Mopar parts, and specially designed elec-

tronic and mechanical tools that can help
prevent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
• Under no circumstances should oil change
intervals exceed12,500 miles (20,000 km)
or 12 months, whichever comes first.
•Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
At Each Stop for Fuel
• Check the engine oil level about 5 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.
• Check the windshield washer solvent and
add if required.Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of the coolant reser-
voir, and brake master cylinder; add as
needed.
• Check all lights and other electrical items
for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
• Completely fill the AdBlue
®(UREA) Fluid
tank.Demanding Vehicle Use
• Restore additive level for AdBlue
®Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
At Every Second Oil Change
• Replace fuel filter.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
Maintenance Plan — Diesel Engine
NOTE:
Once you have carried out the last interven-
tion in the table, continue with the scheduled
servicing, maintaining the frequency indi-
cated in the plan by marking each operation
with a dot or dedicated note. Simply restart-
ing the maintenance from the start of the
plan may cause the allowed interval to be
exceeded for some operations.

Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Add oil only when the level on
the dipstick is below the “MIN” mark. The
total capacity from the MIN mark to the MAX
mark is 1 qt (1 L).
CAUTION!
Overfilling or underfilling the crankcase
will cause oil aeration or loss of oil pres-
sure. This could damage your engine.
NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be
due to diesel fuel that may temporarily be in
the crankcase due to operation of the diesel
particulate filter regeneration strategy. This
fuel will evaporate out under normal opera-
tion.
Never operate the engine with oil level below
the “MIN” mark or above the upper “MAX”
mark.
WARNING!
• Never smoke while working in the engine
compartment: gas and inflammable va-
pors may be present, with the risk of fire.
• Be very careful when working in the
engine compartment when the engine is
hot: you may get burned. Do not get too
close to the radiator cooling fan: the
electric fan may start; danger of injury.
Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!
• Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping
up with an unsuitable fluid could se-
verely damage your car.
• The oil level must never exceed the MAX
mark.
• Always top up using engine oil of the
same specifications as that already in
the engine.
CAUTION!
• If the engine oil is being topped up, wait
for the engine to cool down before loos-
ening the filler cap, particularly for ve-
hicles with aluminium cap (if
equipped). WARNING: risk of burns!
• Overfilling or underfilling the crankcase
will cause aeration or loss of oil pres-
sure. This could damage your engine.
Adding Washer Fluid
The instrument cluster display will indicate
when the washer fluid level is low. When the
sensor detects a low fluid level, the wind-
shield will light on the vehicle graphic outline
and the “WASHER FLUID LOW” message
will be displayed.
The fluid reservoir for the windshield washers
and the rear window washer is shared. The
fluid reservoir is located in the engine com-
partment, be sure to check the fluid level at
regular intervals. Fill the reservoir with wind-
shield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reser-
voir, take some washer fluid and apply it to a
cloth or towel and wipe clean the wiper
