ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and transmis-
sion control systems. When these systems are operating
properly, your vehicle will provide excellent perfor-
mance and fuel economy, as well as engine emissions
well within current government regulations.
If any of these systems require service, the OBD II
system will turn on the “Malfunction Indicator Light
(MIL)”. It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be drivable
and not need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emis-
sions tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
300 MAINTAINING YOUR VEHICLE

WARNING!
•ONLY an authorized service technician should
connect equipment to the OBD II connection port
in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
REPLACEMENT PARTS
Use of genuine parts for normal/scheduled mainte-
nance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by the use of parts which are not quality-equivalent to
genuine parts for maintenance and repairs will not be
covered by the manufacturer ’s warranty.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed
your vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components
which may require servicing or replacement in the
future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage
(Continued)
CAUTION! (Continued)
your engine, transmission, or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time
to check the engine oil level is approximately five
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground,
and approximately five minutes after a fully warmed
engine is shut off, will improve the accuracy of the oil
level readings. Maintain the oil level between the range
markings on the dipstick. The safe range is indicated by
a crosshatch zone. Adding 1 quart (0.9 Liters) of oil
302 MAINTAINING YOUR VEHICLE

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 your authorized dealer, ser-
vice station or governmental agency for advice on how
and where used oil and oil filters can be safely dis-
carded 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
This manufacturer’s engines have a full-flow type dis-
posable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consid-
erably. Only high quality filters should be used toassure most efficient service. MOPAR engine oil filters
are high quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in the “Mainte-
nance Schedules” section for the proper maintenance
intervals.
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 maintenance. 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.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR engine air
cleaner filters are a high quality filter and are recom-
mended.
304 MAINTAINING YOUR VEHICLE

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a perfor-
mance test. Drive belt tension should also be checked at
this time.
WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, located on the
DVD, for further warranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.
CAUTION!

306 MAINTAINING YOUR VEHICLE

Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as MOPAR Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latch-
ing components to ensure proper function. When per-
forming other underhood services, the hood latch,
release mechanism and safety catch should be cleaned
and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant directly into the lock cylinder.
Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield and rear window periodically with a
sponge or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt, waxes, or road
film, and help reduce streaking and smearing.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always
use washer fluid when using the wipers to remove salt
or dirt from a dry windshield or rear window.
Avoid using the wiper blades to remove frost or ice
from the windshield or rear window. Make sure that
they are not frozen to the glass before turning them on
to avoid damaging the blade. Keep the wiper blade out
of contact with petroleum products such as engine oil,
gasoline, etc.
NOTE:Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or replace as
necessary.
