MAINTAINING YOUR VEHICLE

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 automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions 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. Al-
though 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 drivability. The
vehicle must be serviced before any emissions
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.

Loose Fuel Filler Cap Message

After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A “CHECK GASCAP” message
will be displayed in the EVIC (Refer to Section 4 of this
manual). Tighten the gas cap until a

⬙clicking⬙ sound is

heard. This is an indication that the gas cap is properly
tightened.

MAINTAINING YOUR VEHICLE

359

The message will remain displayed until the vehicle
diagnostic system can retest the fuel system. The test will
perform the next time the vehicle is started, if the vehicle
was keyed off above 40°F (4°C) outside temperature and
the following vehicle start is above 40°F (4°C) outside
temperature. It may be possible to have a message that
will not clear due to the test being disabled due to low
outside temperatures. If the test is performed and the
problem is gone, the message will disappear.

If the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL off. See your authorized dealer for service.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS

In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.

Failure to pass could prevent vehicle registration.

For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not

on when the engine is running, and that the OBD II
system is ready for testing.

Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.

Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:

1. Insert your ignition key into the ignition switch.

360

MAINTAINING YOUR VEHICLE

2. Turn the ignition to the ON position, but do not crank
or start the engine.

3. If you crank or start the engine, you will have to start
this test over.

4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.

5. Approximately 15 seconds later, one of two things will
happen:

a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not ready and you should
not

proceed to the I/M station.

b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.

If your OBD II system is not ready, you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.

Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

REPLACEMENT PARTS

Use of genuine MOPAR

威 parts for normal/scheduled

maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR

威 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 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 the required maintenance
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.

362

MAINTAINING YOUR VEHICLE

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 Chrysler Group LLC
dealership 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 maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. 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 about five minutes after a
fully warmed engine is shut off, or before starting the
engine after it has sat overnight.

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the SAFE level range. Adding 1 U.S. Quart
(0.95L) of oil when the level is at the bottom of the SAFE
range will result in the level being at the top of the SAFE
range.

MAINTAINING YOUR VEHICLE

363

CAUTION!

Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.

Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” in Section 8 for
information on this system.

NOTE:

Under no circumstances should oil change

intervals exceed 6,000 miles (10 000 km) or six months,
whichever occurs first.

Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the

manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of Chrysler Material
Standard MS-6395.

American Petroleum Institute (API) Engine Oil
Identification Symbol

This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.

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.

364

MAINTAINING YOUR VEHICLE

Engine Oil Viscosity
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.

The engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section.

NOTE:

Vehicles equipped with a 5.7L engine must use

SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to “Multi-Displacement System” in Section 5 for
more details.

Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.

Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.

Materials Added to Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance

may

impaired

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

MAINTAINING YOUR VEHICLE

365

environment. Contact your local authorized dealer, ser-
vice 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 oil change.

Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high-quality filters should be used to assure most effi-
cient service. MOPAR

威 engine oil filters are high-quality

oil filters and are recommended.

Engine Air Cleaner Filter

Refer to the “Maintenance Schedule” in Section 8 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

威 engine air

cleaner filters are a high quality filter and are
recommended.

366

MAINTAINING YOUR VEHICLE

Maintenance-Free Battery

Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.

WARNING!

• Battery fluid is a corrosive acid solution and can

burn or even blind you. Do not allow battery fluid
to contact your eyes, skin or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.

• Battery gas is flammable and explosive. Keep

flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.

(Continued)

WARNING! (Continued)

• Battery posts, terminals and related accessories

contain lead and lead compounds. Wash hands
after handling.

CAUTION!

• It is essential when replacing the cables on the

battery that the positive cable is attached to the
positive post, and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and (-) negative and identified on the
battery case.

• If a “fast charger” is used while battery is in the

vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage.

MAINTAINING YOUR VEHICLE

367

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 performance
test. Drive belt condition should also be checked at this
time.

CAUTION!

Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.

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
Section 3 of the Warranty Information book, lo-
cated on the DVD, for further warranty informa-
tion.

• The air conditioning system contains refrigerant

under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
