MAINTAINING YOUR VEHICLE 263
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers 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 (anti-
freeze) 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 (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•
Maintain engine coolant (antifreeze) concentration 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 necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
To ensure brake system performance, all brake system com-
ponents should be inspected periodically. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly an accident. 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.

Master Cylinder — Brake Fluid Level Check
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 perform-
ing underhood services.
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.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
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 the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information. Use of a
brake fluid that may have a lower initial boiling point or
unidentified as to specification, may result in sudden brake
failure during hard prolonged braking.
WARNING!
•Use only manufacturer ’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. 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 cylin-
der 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 brak-
ing, resulting in sudden brake failure. This could
result in a accident.
• 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.

280 MAINTAINING YOUR VEHICLE
WARNING!(Continued)
•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 an accident.
Change Brake Fluid
Brake fluid will tend to absorb moisture from the atmo-
sphere over time. If the fluid becomes contaminated with
water, brake performance will deteriorate. Therefore, the
brake fluid must be changed at the intervals specified in
the “Maintenance Schedule.” Refer to “Maintenance
Schedule” for further information. See your authorized
dealer for service.
Manual Transmission
Transmission Fluid Level Check
Check the fluid in the transmission when performing other
underbody services.
Check the fluid level by removing the fill plug located on
the left side of the transmission. The fluid level should be
approximately 1/4 in (6.4 mm) below the bottom of the fill
hole. Add fluid, if necessary, to maintain the proper level. Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
NOTE: DO NOT
overfill transmission, damage can occur.
CAUTION!
Using a transmission fluid other than the manufactur-
er’s recommended fluid may cause deterioration in
transmission shift quality and/or damage to the trans-
mission. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
Change Transmission Fluid
Refer to “Maintenance Schedule” for the proper mainte-
nance intervals. If contaminated with water, change the
fluid immediately. See your authorized dealer for service.
Hydraulic Clutch
Master Cylinder — Clutch Fluid Level Check
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 manufactur-
er’s recommended brake fluid. Refer to “Fluids, Lubri-
cants, And Genuine Parts” in “Maintaining Your Vehicle”
for further information.

•Use a high quality cleaner wax, such as MOPAR Cleaner
Wax to remove road film, stains and to protect your
paint finish. Take care never to scratch the paint.
•
Avoid using abrasive compounds and power buffing that
may diminish the gloss or thin out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning materials such
as steel wool or scouring powder that will scratch
metal and painted surfaces.
•
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly using
mild (neutral Ph) soap and water to maintain their luster
and to prevent corrosion. Wash wheels with the same soap
solution recommended for the body of the vehicle.
Your wheels are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride,
etc., and other road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge and mild soap
to wipe away promptly. Do not use harsh chemicals or a stiff brush. They can damage the wheel’s protective coating
that helps keep them from corroding and tarnishing.
NOTE:
Many aftermarket wheel cleaners contain strong
acids or strong alkaline additives that can harm the wheel
surface.
CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
These products and automatic car washes may damage the
wheel’s protective finish. Such damage is not covered by
the New Vehicle Limited Warranty. Only car wash soap,
MOPAR Wheel Cleaner or equivalent is recommended.
When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent dam-
age to the wheels. Mopar Wheel Treatment, Mopar Chrome
Cleaner, or their equivalent is recommended or select a
non-abrasive, non-acidic cleaner for aluminum or chrome
wheels. Do not use any products on Dark Vapor or Black
Satin Chrome Wheels. They will permanently damage this
finish and such damage is not covered by the New Vehicle
Limited Warranty.

MAINTAINING YOUR VEHICLE 283
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel’s protective finish. Such damage is
not covered by the New Vehicle Limited Warranty.
Only car wash soap, MOPAR Wheel Cleaner or equiva-
lent is recommended.
NOTE: If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with wheel
cleaner, drive your vehicle for a few minutes before doing
so. Driving the vehicle and applying the brakes when
stopping will reduce the risk of brake rotor corrosion.
Dark Vapor Or Black Satin Chrome Wheels
CAUTION!
If your vehicle is equipped with Dark Vapor or Black
Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not
covered by the New Vehicle Limited Warranty. USE
ONLY MILD SOAP AND WATER WITH A SOFT
(Continued)
CAUTION! (Continued)
CLOTH. Used on a regular basis; this is all that is
required to maintain this finish.
Interior Care
Use MOPAR Total Clean to clean fabric upholstery and
carpeting.
Use MOPAR Total Clean to clean vinyl upholstery.
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.
Application of a leather conditioner is not required to
maintain the original condition.
284 MAINTAINING YOUR VEHICLE
CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
VEHICLE STORAGE
We recommend that you follow these guidelines for storing
your vehicle for extended periods.
• Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than two months, add an anti-oxidant fuel stabilizer to
the fuel tank.
• Change the oil to remove any corrosive combustion
related acids in the crankcase. •
Check that the radiator coolant level of protection is to at
least -20°F (-29°C).
• Make sure that all tires are inflated to the optimum
pressure.
• Wash and wax the vehicle to protect the finish.
• Store the vehicle in a dry, well-ventilated location.
• Move the wiper blades away from the windshield.
• Block the wheels. Do not apply the parking brake.
• Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
• For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
• If the vehicle will be subjected to freezing temperatures,
either remove the battery and store it in a dry, well
ventilated area or connect a trickle charger (1.5 Amp)
with automatic shutdown / overcharge protection to the
battery. However, do not leave the trickle charger
hooked up to the battery without being plugged in to a
110 Volt AC outlet, as this will result in further drain on
