NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
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 ve-
hicle with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in serious
personal 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.
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!
•
Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, for further warranty
information.
• The air conditioning system contains refrigerant un-
der 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 condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
234 SERVICING AND MAINTENANCE

WARNING!(Continued)
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 mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.
Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS-12106) only 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.
Cooling System — Drain, Flush And Refill
NOTE: Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed to
be added to the system please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.

SERVICING AND MAINTENANCE 239

Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. To prevent ingestion by animals or children,
do not store ethylene glycol-based coolant in open contain-
ers or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency assistance
immediately. Clean up any ground spills immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is adequate.
With engine off and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the “MIN” and
“MAX” marks.
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 pro-
tection of your engine which contains aluminum com-
ponents.
• 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
242 SERVICING AND MAINTENANCE

the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
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.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. 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

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
WARNING:
Operating, servicing and maintaining a
passenger vehicle or off-road highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to
the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle.
