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. Poor perfor -
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary.
Wiper Blade Removal/Installation

1. Lift the wiper arm to raise the wiper blade off of the glass, until the wiper arm is in the full up position.

2. To disengage the wiper blade from the wiper arm, press the release tab on the wiper blade and while
holding the wiper arm with one hand, slide the wiper
blade down towards the base of the wiper arm.

SERVICING AND MAINTENANCE237
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.
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 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 discon -
nected or removed, such as when diagnostic testing, or
for prolonged periods during very rough idle or malfunc -
tioning operating conditions.
NOTE:The vehicle exhaust system may be equipped with an Elec -
tronic Exhaust Valve (EEV) system, if the exhaust system is
replaced with aftermarket products a Malfunction Indi -
cator Lamp (MIL) will illuminate.
COOLING SYSTEM WARNING!
 Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO,
Úpage 196.
 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 effective -
ness 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 operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
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 radiator 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, discon -
nect the fan motor lead or turn the ignition to the OFF
position. The fan is temperature controlled and can
start at any time the ignition is in the ON position.

240SERVICING AND MAINTENANCE
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically
Úpage 224.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder immediately if
the Brake System Warning Light indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the 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.
However, low fluid level may be caused by a leak and a
checkup may be needed. Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed
container to avoid contamination from foreign matter or
moisture
Úpage 278.
CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a segregated volume
of fluid within the brake system master cylinder reservoir.
In the event of leakage or wear, use only the
manufacturer's recommended brake fluid
Úpage 278.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on the left
side of the transmission. The fluid level should be
1/4 inch (6.4mm) below the bottom of the fill hole.
Add fluid, if necessary, to maintain the proper level
Úpage 278.
Change Transmission Fluid
If contaminated with water, change the fluid immediately.
See an authorized dealer for service.
For the proper maintenance intervals
Úpage 224.
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 manufacturer's recommended brake fluid Úpage 278. 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 mois -
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master
cylinder reservoir 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.
CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may cause
deterioration in transmission shift quality and/or
damage to the transmission

5. Reinstall the bulb and socket assembly into the headlamp assembly, and then turn it clockwise. 6. Reinstall the access cap making sure it is seated into
the housing and turn cap clockwise to engage locking
lugs. Visually, you should be unable to see the blue
O-ring gasket. The access cap should be uniformly
seated and you should not be able to pull the access
cap off without turning it counterclockwise.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the bulb
comes in contact with any oily surface, clean the bulb
with rubbing alcohol.
CAUTION!
If the access cap is not installed correctly after bulb
replacement, the lamp becomes susceptible to dust,
condensation, and water intrusion. This may ultimately
lead to an inoperative lamp. If the access cap cannot
be installed correctly, please return to an authorized
dealer for proper repair or access cap replacement if
necessary.

SERVICING AND MAINTENANCE263
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.

Tire Tread

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
Driving style.
 Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire
replacement.
 Distance driven.
 Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle sched-
uled maintenance is highly recommended.
NOTE:Wheel valve stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The
manufacturer strongly recommends using tires equivalent
to the originals in size, quality and performance when
replacement is needed
Úpage 263. Refer to the Tire And
Loading Information Placard or the Vehicle Certification
Label for the size designation of your tire. The Load Index
and Speed Symbol for your tire will be found on the original
equipment tire sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more information
relating to the Load Index and Speed Symbol of a tire
Úpage 253.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds continuously
when you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
1 — Tread Wear Indicators
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting in
serious injury or death.8

Cleaning Plastic Instrument Cluster
Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
Clean with a wet soft cloth. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
cloth. Dry with a soft cloth.
LEATHER SURFACES
Mopar® Total Clean is specifically recommended for
leather upholstery. Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt can
act as an abrasive and damage the leather upholstery and
should be removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and Mopar®
Total Clean. Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do not use
polishes, oils, cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your leather upholstery.
NOTE:If equipped with light colored leather, it tends to show any
foreign material, dirt, and fabric dye transfer more so than
darker colors. The leather is designed for easy cleaning,
and the manufacturer recommends Mopar® total care
leather cleaner applied on a cloth to clean the leather
seats as needed.
GLASS SURFACES
All glass surfaces should be cleaned on a regular basis
with Mopar® Glass Cleaner, or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear
window equipped with electric defrosters or windows
equipped with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the elements.
When cleaning the rearview mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror.
CAUTION!
Do not use alcohol and alcohol-based and/or
ketone-based cleaning products to clean leather
upholstery, as damage to the upholstery may result.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is on the left front corner of the instrument panel.
The VIN is visible from outside of the vehicle through the
windshield.

Windshield VIN Location

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 lose normal
capability, the remaining system will still function. There
will be some loss of overall braking effectiveness.This may be evident by increased pedal travel during
application, greater pedal force required to slow or stop,
and potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine off),
the brakes will still function. 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.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket
is fully engaged on the lug nut/bolt (do not insert it
halfway).
NOTE:If in doubt about the correct tightness, have them checked
with a torque wrench by an authorized dealer or service
station.
