ENGINE OIL
Engine Oil Selection
For best performance and maximum protection
under all types of operating conditions, FCA only
recommends engine oils that are API Certified
and meet the requirements of FCA 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). FCA only
recommends API Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
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
FCA 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.
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 mechanic.
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.

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.
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 the manufacturer for
your air conditioning system. Some unap -
proved 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,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced technician.
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.

SERVICING AND MAINTENANCE221
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 chattering, marks, water lines or wet
spots are present, clean the wiper blades or
replace as necessary.
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.

BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically Úpage 212.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood
service or immediately if the brake system
warning lamp indicates system failure. If
necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the
top of the master cylinder area before removing
cap. With disc brakes the fluid level can be
expected to fall as the brake linings wear. However, an unexpected drop in fluid level may
be caused by a leak and a system check should
be conducted Ú
page 268.
AUTOMATIC TRANSMISSION
Selection Of Lubricant

It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer’s specified transmission fluid

Ú

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 FCA's recommended brake fluid
Ú page 268. 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.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found
on the left front corner of the instrument panel,
visible through the windshield.
Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will be
some loss of overall braking effectiveness. You
may notice increased pedal travel during
application, greater pedal force required to slow
or stop, and potential activation of the “Brake
System Warning Light”.
In the event power assist is lost for any reason
(i.e., repeated brake applications with the
engine off), the brakes will still function.
However, the effort required to brake the
vehicle will be much greater than that required
with the power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a six sided (hex)
deep wall socket.
