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
engine oil certification mark and the correct SAE
viscosity grade number 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 190.
NOTE:Be sure to follow the Severe Duty Conditions main -
tenance interval if applicable Ú page 189.Engine Air Cleaner Filter Selection
The quality of replacement filters varies
considerably. Only high quality Mopar® certified
filters should be used.
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 tension
should also be checked at this time.
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
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.
WARNING!
Use only refrigerants and compressor lubri
-
cants approved by FCA 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,
for further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,

Refrigerant Recovery And Recycling —
R-1234yf
R-1234yf Air Conditioning Refrigerant is a hydroflu -
oroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using recovery
and recycling equipment.
NOTE:Use only the manufacturer approved A/C system
PAG compressor oil, and refrigerants.
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 ensure 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 latching components to ensure proper
function. When performing 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 Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant directly
into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove
accumulations of salt or road film.
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.
Avoid using the wiper blades to remove frost or ice
from the windshield. Keep the blade rubber out of
contact with petroleum products such as engine
oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. If chat -
tering, marks, water lines or wet spots are present,
clean the wiper blades or replace as necessary.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.

Wiper Service Position
If it is necessary to lift the blade from the
windshield (In the event of snow or blade
replacement) proceed as directed:

1. Rotate the end of the multifunction lever to
the OFF position.

2. Turn the ignition to the MAR (ON/RUN) position then to STOP.
3. After turning the ignition to the STOP, within two minutes move the right stalk upward, into
the unstable (“anti-panic”) position, for at least
half of a second. The windshield wiper then
executes part of a stroke; at each command,
approximately 1/3 of a normal wiper stroke is
triggered.
NOTE:The previous operation can be repeated up to
three times in order to move the blades to the most
suitable position.
4. Lift the blade from the windshield and proceed with the required operation.
5. Carefully lower the blade, bringing it back in contact with the windshield.
6. Bring the blade to the initial rest position, turning the ignition to MAR (ON/RUN).
NOTE:Do not operate the wiper with the blades lifted
from the windshield.
EXHAUST SYSTEM
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected
inside the vehicle; or when the underside or rear of
the vehicle is damaged; have an authorized
technician inspect the complete exhaust system
and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes
to seep into the passenger compartment. In
addition, have the exhaust system inspected each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you
Ú page 170.

A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact
with your exhaust system. Do not park or operate
your vehicle in areas where your exhaust system
can contact anything that can burn.

CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.

22_VM_OM_EN_USC_t.book Page 198

SERVICING AND MAINTENANCE199
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagnostic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM Engine Coolant Checks
Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine coolant is
dirty, the system should be drained, flushed, and
refilled with fresh Organic Additive Technology
(OAT) coolant (conforming to MS.90032) by an
authorized dealer. 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 engine cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the coolant recovery bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.WARNING!
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 open a
cooling system pressure cap when the radi -
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF position. The fan is tempera -
ture controlled and can start at any time the
ignition is in the ON position.

Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo-
meters of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from rain,
snow, or high humidity accumulating on the
radiator and being vaporized when the thermostat
opens, allowing hot engine coolant to enter the
radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks, the
vehicle may be safely driven. The vapor will soon
dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro -
sion 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 neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Ú page 190.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or
immediately if the Brake Warning Light is
illuminated.
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 requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed. Use only the manufacturer
recommended brake fluid Ú page 241.
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 temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only the manufacturer recommended
brake fluid Úpage 241. Using the wrong type
of brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.

22_VM_OM_EN_USC_t.book Page 202

204SERVICING AND MAINTENANCE
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 has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
