HAZARD WARNING FLASHERSThe Hazard Warning flasher switch is located
on the switch bank just above the climate
controls.Press the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals will
flash on and off to warn oncoming
traffic of an emergency. Press the switch a
second time to turn off the Hazard Warning
flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.IF YOUR ENGINE OVERHEATSIn any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease the engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age your vehicle. If the temperature gauge
reads HOT (H), pull over and stop the vehicle.
Idle the vehicle with the air conditioner turned
off until the pointer drops back into the normal
range. If the pointer remains on HOT (H), and
you hear continuous chimes, turn the engine
off immediately and call for service.
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
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.

WARNING!
Do not attempt jump-starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
Preparations For Jump-StartThe battery in your vehicle is located under the
passenger’s front seat. There are remote loca-
tions located under the hood to assist in jump-
starting.
WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is on. You can
be injured by moving fan blades.
• Remove any metal jewelry such as watch
bands or bracelets that might make an
inadvertent electrical contact. You could be
seriously injured.
• Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen
gas which is flammable and explosive.
Keep open flames or sparks away from the
battery.
1. Set the parking brake, shift the automatic
transmission into PARK and turn the ignition to
LOCK.
2. Turn off the heater, radio, and all unneces-
sary electrical accessories.
3. Remove the protective cover over the re-
mote positive (+)battery post. Pull upward on
the cover to remove it. 4. If using another vehicle to jump-start the
battery, park the vehicle within the jumper
cables reach, set the parking brake and make
sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in
personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result
in damage to the charging system of the
booster vehicle or the discharged vehicle.
1. Connect the positive (+)end of the jumper
cable to the remote positive (+)post of the
discharged vehicle.

4. Install the wiper blade pivot pin into the
wiper blade holder at the end of the wiper arm,
and firmly press the wiper blade until it snaps
into place.
5. Lower the wiper blade and snap the pivot
cap into place.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating information can be found on
most washer fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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 under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
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. To
avoid breathing CO, refer to “Safety Tips/
Exhaust Gas” in “Things To Do Before Starting
Your Vehicle” for further information.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.
307

CAUTION!
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 ve-
hicle serviced promptly. Continued operation
of your vehicle with a severe malfunction
could cause the converter to overheat, result-
ing in possible damage to the converter and
vehicle.
NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such ma-
terials 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.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tuneup 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 disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
Cooling System
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
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves,
308

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 tight-
ness of the connection at the coolant recovery
bottle and radiator. Inspect the entire system
for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling sys-
tem pressure cap for proper vacuum sealing by
draining a small amount of engine coolant
(antifreeze) from the radiator drain cock. If the
cap is sealing properly, the engine coolant
(antifreeze) will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOL-
ANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty and
contains a considerable amount of sediment,
clean and flush with reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of the old engine coolant (antifreeze).Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended en-
gine coolant (antifreeze). Refer to “Fluids, Lu-
bricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
CAUTION!
•
Mixing of engine coolant (antifreeze), other
than the specified HOAT engine coolant
(antifreeze), may result in engine damage
and may decrease corrosion protection. If a
non-HOAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, it should be replaced with the
specified engine coolant (antifreeze) as
soon as possible.
(Continued)
CAUTION!(Continued)
• Do not use water alone or alcohol based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or antirust
products, as they may not be compatible
with the engine coolant (antifreeze) and
may plug the radiator.
• This vehicle has not been designed for use
with Propylene Glycol-based engine cool-
ant (antifreeze). Use of Propylene Glycol-
based engine coolant (antifreeze) is not
recommended.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (antifreeze) that allows extended
maintenance intervals. This engine coolant (an-
tifreeze) can be used up to 5 Years or
105,000 miles (168 000 km) before replace-
ment. To prevent reducing this extended main-
tenance period, it is important that you use the
same engine coolant (antifreeze) throughout the
life of your vehicle. Please review these recom-
mendations for using Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze).
309

When adding engine coolant (antifreeze):
•
The manufacturer recommends using MOPAR
Antifreeze/ Coolant 5–Year/100,000 Mile For-
mula HOAT (Hybrid Organic Additive Technol-
ogy) or equivalent.
• Mix a minimum solution of 50% HOAT engine
coolant (antifreeze) and distilled water. Use
higher concentrations (not to exceed 70%) if
temperatures below -34°F (-37°C) are antici-
pated.
• Use only high purity water such as distilled
or deionized water when mixing the water/
engine coolant (antifreeze) solution. The use
of lower quality water will reduce the amount
of corrosion protection in the engine cooling
system.
Please note that it is the owner’s responsibility
to maintain the proper level of protection
against freezing according to the temperatures
occurring in the area where the vehicle is
operated.
NOTE:
Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (an- tifreeze) and will require more frequent en-
gine coolant (antifreeze) changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to the
radiator from the coolant recovery tank.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
•
The warning words DO NOT OPEN HOT
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not remove
the pressure cap while the system is hot or
under pressure.
(Continued)
WARNING!(Continued)
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant
(antifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals
and children, do not store ethylene glycol-
based engine coolant (antifreeze) in open con-
tainers 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 bottle provides a quick visual
method for determining that the engine coolant
(antifreeze) level is adequate. With the engine
idling, and warm to normal operating tempera-
ture, the level of the engine coolant (antifreeze)
in the bottle should be between the ranges
indicated on the bottle.
310

The radiator normally remains completely full,
so there is no need to remove the radiator cap,
unless checking for engine coolant (antifreeze)
freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, it should
be added to the coolant bottle. Do not overfill.
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 re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) 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 recovery bottle.
• Check engine coolant (antifreeze) freeze
point in the radiator and in the coolant recov-
ery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant
recovery bottle must also be protected
against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, or if the level in the
coolant recovery bottle does not drop when
the engine cools, the cooling system should
be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concen-
tration at 50% HOAT engine coolant (anti-
freeze) (minimum) and distilled water for
proper corrosion protection of your engine,
which contains aluminum components.
• Make sure that the radiator and coolant
recovery bottle hoses are not kinked or ob-
structed. •
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 nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory cooling performance, poor gas mileage,
and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be peri-
odically inspected. Refer to the “Maintenance
Schedule” for the proper maintenance inter-
vals.
WARNING!
Riding the brakes can lead to brake failure
and possibly 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.
