Synthetic Engine Oils
There are a number of engine oils being pro-
moted as either synthetic or semi-synthetic. If
you chose to use such a product, use only those
oils that are approved to FCA MS-6395 or FCA
Material Standard 9.55535-CR1. Follow the
maintenance schedule that describes your driv-
ing type.
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, service station or gov-
ernmental agency for advice on how and where
used oil and oil filters can be safely discarded in
your area.Engine Oil FilterThe 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 oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies
considerably. Only high quality filters should be
used to assure most efficient service. MOPAR
engine oil filters are a high quality oil filter and
are recommended.
Engine Air Cleaner FilterRefer to the “Maintenance Schedule” in the
“Maintenance 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

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 per-
sonal 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 recommended.

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency and is an
ozone-saving product. However, the manufac-
turer recommends that air conditioning service
be performed by authorized dealer or other
service facilities using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C sys-
tem PAG compressor oil and refrigerants.
A/C Air Filter
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
WARNING!
Do not remove the A/C air filter while the
vehicle is running, or while the ignition is in
the ACC or ON/RUN mode. With the A/C air
filter removed and the blower operating, the
blower can contact hands and may propel
dirt and debris into your eyes, resulting in
personal injury.
The A/C air filter is located in the fresh air inlet
behind the glove compartment. Perform the
following procedure to replace the filter:
1. Open the glove compartment and remove all
contents.
2. Push in on the sides of the glove compart-
ment and lower the door.
3. Pivot the glove compartment downward.

NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•Do not shut off the engine or interrupt the
ignition, when the transmission is in gear and
the vehicle is in motion.
•Do not try to start the engine by pushing or
towing the vehicle.
•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunction-
ing operating conditions.Cooling System
WARNING!
•When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition switch to the OFF position. The
fan is temperature controlled and can start
at any time the ignition switch is in the ON
position.
•You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine cool-
ant (antifreeze) is dirty or rusty in appearance,
the system should be drained, flushed, and
refilled with fresh engine coolant (antifreeze).Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the bottle and radiator.
Inspect the entire system for leaks.
Cooling System – Drain, Flush, And Refill
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
If the engine coolant (antifreeze) is dirty or
contains a considerable amount of sediment,
clean and flush with a reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of old engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.

•If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
•Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
•Do not change the thermostat for Summer or
Winter operation. If replacement is ever nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be in-spected periodically. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be
checked when performing under hood services,
or immediately if the brake system warning light
is on.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the require-
ments described on the brake fluid reservoir.
Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be
checked when the pads are replaced. However,low fluid level may be caused by a leak and a
checkup may be needed.
NOTE:
If your vehicle is equipped with a manual
transmission, the brake fluid reservoir sup-
plies fluid to both the brake system and the
clutch release system. The two systems are
separated in the reservoir, and a leak in one
system will not affect the other system. The
manual transmission clutch release system
should not require fluid replacement during
the life of the vehicle. If the brake fluid
reservoir is low and the brake system does
not indicate any leaks or other problems, it
may be a result of a leak in the hydraulic
clutch release system. See your local autho-
rized dealer for service.
Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.

Special Additives
The manufacturer strongly recommends
against using any special additives in the trans-
mission.
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes for diagnosing fluid leaks. Avoid
using transmission sealers as they may ad-
versely affect seals.
CAUTION!
Do not use chemical flushes in your trans-
mission as the chemicals can damage your
transmission components. Such damage is
not covered by the New Vehicle Limited
Warranty.
Fluid Level Check
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions.Routine fluid level checks are not required,
therefore the transmission filler tube is capped
and no dipstick is provided. Your authorized
dealer can check your transmission fluid level
using special service tools. If you notice fluid
leakage or transmission malfunction, visit your
authorized dealer immediately to have the
transmission fluid level checked. Operating the
vehicle with an improper fluid level can cause
severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit your
authorized dealer immediately. Severe trans-
mission damage may occur. Your authorized
dealer has the proper tools to adjust the fluid
level accurately.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle. However, if
the vehicle is frequently driven on rough or
unpaved roads, on mountain roads, on short
trips, or in heavy city traffic during hot weather,or is used for frequent trailer towing, police,
fleet, taxi, etc., change the fluid as indicated in
the Maintenance Schedule. In addition, change
the fluid and filter if the fluid becomes contami-
nated (with water, etc.), or if the transmission is
disassembled for any reason.
Automatic Transmission (CVT) — If
Equipped
Selection Of Lubricant (CVT)
It is important to use the proper transmission
fluid to ensure optimum transmission perfor-
mance and life. Use only the manufacturer’s
specified transmission fluid which has the spe-
cial friction coefficient additives necessary for
proper steel belt traction on the drive and driven
pulleys. Refer to “Fluids, Lubricants, And Genu-
ine Parts” in this section for fluid specifications.
It is important to maintain the transmission fluid
at the correct level using the recommended
fluid.
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
