Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
NOTE: If the defrost feature is not functioning, the
cause should be located and corrected immediately by an
authorized service center. The windshield could fog up
while driving and obscure your visibility.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure. Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. In addition, if
gasoline fumes are detected or fuel, power steering fluid,
transmission fluid, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
When the ignition switch is in the ON position, the
pointer will show the level of fuel remaining in the
fuel tank.
2. Fuel Door Reminder
This is a reminder that the Fuel Filler Door is
located on the left side of the vehicle.
3. Temperature Gauge
The temperature gauge shows engine coolant tem-
perature. Any reading below the red area of the
gauge shows that the engine cooling system is
operating properly. The gauge pointer may show a
higher than normal temperature when driving in hot
weather, up mountain grades, in heavy stop and go
traffic, or when towing a trailer. If the pointer rises to the H (red) mark, the instrument
cluster will sound a chime. 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 the H (red) mark, turn the engine off
immediately and call for service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning is
on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
4. Speedometer
Indicates vehicle speed in miles per hour Ð MPH.170 UNDERSTANDING YOUR INSTRUMENT PANEL

² Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the RECIRCULATION button to return to out-
side air. Some temp/humidity conditions will cause
captured interior air to condense on windows and
hamper visibility. For this reason, the system will not
allow Recirculation to be selected while in floor, de-
frost, or defrost/floor mode. Attempting to use the
Recirculation while in these modes will cause the LED
in the CONTROL button to blink and then turn off.
² Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pressing the RECIRCULATION button.
However, under certain conditions, while in Auto-
matic Mode, the system is blowing air out the defrost
vents. When these conditions are present, and the
RECIRCULATION button is pressed, the indicator will
flash and then turn off. This tells you that you are
unable to go into recirculation mode at this time. If you would like the system to go into Recirculation mode,
you must first move the Mode Knob to Panel, Panel/
Floor and then press the RECIRCULATION button.
This feature reduces the possibility of window fog-
ging.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to ªMaintenance Proceduresº in Section 7 of this manual
for proper coolant selection.252 UNDERSTANDING YOUR INSTRUMENT PANEL

The following conditions must be met before the engine
will remote start:
² Automatic Transaxle in PARK
² All doors are closed
² Hood is closed
² Hazard Switch is off
² Brake Switch is inactive
² Key is not in the ignition
² Battery is at an acceptable charge level
² PANIC button on key fob is not depressed ENGINE BLOCK HEATER Ð IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is bundled under the hood
between the headlight assembly and the Totally Inte-
grated Power Module (Fuse Box) on the driver's side of
the vehicle.
WARNING!Remember to disconnect the cord before driving.
Damage to the 110-115 Volt electrical cord could cause
electrocution.266 STARTING AND OPERATING

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
ENGINE OIL OVERHEATING (2.4L ENGINE ONLY)
Ð IF EQUIPPED
During sustained high-speed driving or trailer tow up
long grades on a hot day, the engine oil temperature may
become too hot. If this happens, the ªHOTOILº message
flashes in the odometer and the vehicle speed will be
reduced to 53 mph (85 km/h) until the engine oil
temperature is reduced. NOTE: The vehicle speed is reduced to a maximum of
53 mph (85 km/h). You may of course, reduce your
vehicle speed further if needed.
JACKING AND TIRE CHANGING
WARNING!² Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
² The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.350 WHAT TO DO IN EMERGENCIES

into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for an oil
change or lubrication. 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 unconscious and can
eventually poison you. To avoid breathing CO, refer
to Exhaust Gas in the Safety Tips section of this
manual. COOLING SYSTEM
WARNING!² When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the LOCK position. The fan is tempera-
ture controlled and can start at anytime the igni-
tion switch is in the ON position.
² You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don't open the
hood until the radiator has had time to cool. Never
try to open a cooling system pressure cap when the
radiator is hot.388 MAINTAINING YOUR VEHICLE

Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed, and refilled with
fresh coolant. 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.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks. Cooling System Ð Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the
intervals shown in the ªMaintenance Scheduleº in Sec-
tion 8 of this manual.
If the solution is dirty or contains a considerable amount
of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze solution.
Selection Of Coolant
Use only the manufacturer's recommended coolant, refer
to ªFluids, Lubricants, and Genuine Partsº for correct
coolant type. MAINTAINING YOUR VEHICLE 389

CAUTION!² Mixing of coolants other than specified HOAT
engine coolants, may result in engine damage and
may decrease corrosion protection. If a non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
² Do not use plain water alone or alcohol-base
engine coolant (antifreeze) products. Do not use
additional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant and may plug the radiator.
² This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended. Adding Coolant
Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to 5 Years or 100,000 mi (160 000
km) before replacement. To prevent reducing this ex-
tended maintenance period, it is important that you use
the same coolant throughout the life of your vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) coolant.
When adding coolant:
² The manufacturer recommends using Mopar t
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
² Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below 2 34F( 2 37 C) are
anticipated.390 MAINTAINING YOUR VEHICLE

² Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
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 main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE: Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to ensure that coolant will return to the
radiator from the coolant recovery bottle. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!² The warning words ªDO NOT OPEN HOTº on
the cooling system pressure cap are a safety pre-
caution. Never add coolant when the engine is
overheated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scald-
ing or injury, do not remove the pressure cap while
the system is hot or under pressure.
² Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result. MAINTAINING YOUR VEHICLE 391

Disposal of Used Engine Coolant
Used ethylene glycol based engine coolant is a regulated
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 engine coolant in open
containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Level
4 Cylinder Engines Ð the coolant bottle provides a quick
visual method for determining that the coolant level is
adequate. With the engine idling and warm to normal
operating temperature, the level of the coolant in the
bottle should be between the ªADDº and ªFULLº lines,
shown on the bottle. 6 Cylinder Engines Ð the level of the coolant in the
pressurized coolant bottle should be between the
ªCOLDº and ªFULLº range on the bottle when the
engine is cold.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing coolant. 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 coolant 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 nor-
mally a result of moisture from rain, snow, or high392 MAINTAINING YOUR VEHICLE
