MAINTENANCE PLAN – GASOLINE ENGINE
Refer to the maintenance plan on the following pages for required maintenance. More frequent maintenance may be needed in severe conditions, such as dusty
areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
NOTE:Using white lithium grease, lubricate the door hinge pivot joints twice a year to prevent premature wear.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner filter if using in dusty or off-road conditions. Replace the engine air cleaner filter, if necessary.
Inspect battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect automatic transmission fluid if equipped with dipstick.
Inspect brake pads, shoes, rotors, drums, hoses and parking brake.
Inspect front end, and lubricate — If equipped with serviceable fittings.
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty condi-
tions.8

Required Maintenance Intervals
Refer to the maintenance plan on the following
pages for the required maintenance intervals.
More frequent maintenance may be needed in
severe conditions, such as dusty areas and very
short trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.
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 reservoir,
brake master cylinder, and automatic transmis -
sion, and add as needed. At Each Oil Change

Change the engine oil filter.
Inspect the exhaust system.
Check the tire inflation pressures and look for
unusual wear or damage. Rotate at the first sign
of irregular wear.
Inspect engine air cleaner filter. Replace the
engine air cleaner filter, if necessary.
Inspect the CV/Universal joints.
Check the coolant level, hoses, and clamps.
Inspect front end, and lubricate — If equipped
with serviceable fittings.
Inspect and replace the Evaporative System
Fresh Air Filter as necessary, replacement may
be more frequent if vehicle is operated in
extreme dusty conditions.
Inspection and service should also be performed
anytime a malfunction is observed or suspected.
Retain all receipts.
NOTE:Using white lithium grease, lubricate the door
hinge pivot joints twice a year to prevent
premature wear.
OIL CHANGE INDICATOR SYSTEM —
D
IESEL ENGINE
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
display. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate depending on your
personal driving style. Failure to change the engine
oil per the maintenance schedule can result in
internal engine damage.
An 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 an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú page 81.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or 12 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 12 months, whichever comes first.CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified
by the API. The manufacturer only recommends API
trademark oils.
The API Starburst trademark certifies
0W-20, 0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40
and 5W-40 engine oil.
For diesel engines, oils with a high ash content may
produce damaging deposits on cylinder head
valves and/or after-treatment system damage. A
maximum sulfated ash content of 1.00 mass % is
recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum-based oil. Also,
synthetic oil must meet the same performance
specifications as petroleum oil.
Synthetic Engine Oils
Your engine was designed for synthetic engine oils,
only use synthetic API approved engine oils.
Synthetic engine oils which do not have both the
correct API trademark and the correct SAE viscosity
grade numbers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition 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 additives.
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 an
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 OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals
Úpage 329.
NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality filters
should be used to ensure most efficient service.
Mopar® engine air cleaner filters are a high quality
filter and are recommended.
CAUTION!
Do not use chemical flushes in your engine oil as
the chemicals can damage your engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in the
case of engine backfire. Do not remove the air
induction system (air cleaner, hoses, etc.) unless
such removal is necessary for repair or mainte -
nance. Make sure that no one is near the engine
compartment before starting the vehicle with
the air induction system (air cleaner, hoses, etc.)
removed. Failure to do so can result in serious
personal injury.
