ON. If the LED is not lit during starting and/or the light
stays on or comes ON while driving, have the system
checked by an authorized dealer.
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 defroster is not working or you are unable
to feel air against the windshield in defrost mode, please
see your authorized dealer service center for repairs.
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. Also, if gasoline
fumes are detected or fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
2. Fuel Door Reminder
The arrow in this symbol 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 tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads
ªHª, 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 ªHº, and you hear continuous chimes,
turn the engine off immediately, and call an autho-
rized dealer for service.

HEADLINER Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
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 section 7, ªMaintenance Proceduresº, of this manual
for proper coolant selection.
WINTER OPERATION
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7,ªMaintenance Proceduresº, of this manual for proper
coolant selection. Use of the air RECIRCULATION mode
during winter months is not recommended because it
may cause window fogging.
VACATION/STORAGE
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
WINDOW FOGGING
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select DE-
FROST or MIX mode and increase the front blower
speed. Do not use the RECIRCULATION mode without
A/C for long periods, as fogging may occur.

If the engine shows no sign of starting after two 15±
second intervals of cranking with the accelerator pedal
held to the floor, the ªNormal Startingº procedure should
be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.
ENGINE BLOCK HEATER Ð IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the
electrical cord to a standard 110-115 volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver's side of the vehicle. It has a removable cap
that is located on the driver side of the Integrated Power
Module.
WARNING!
Remember to disconnect the electrical cord before
driving. Damage to the 110-115 volt electrical cord
could cause electrocution.

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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, 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
ªHº, turn the engine off immediately, and call for
service.
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, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.

COOLING SYSTEM
WARNING!
²When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at anytime the ignition
switch is in the ON position.
²You 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.
Coolant Checks
Check the 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.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant 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 RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
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 Fluids, Lubricants and Genuine Parts for correct
coolant type.
CAUTION!
Mixing of coolants other than specified Hybrid Or-
ganic Additive Technology (HOAT) engine coolants,
may result in engine damage and may decrease
corrosion protection. If a non-HOAT coolant is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant as soon
as possible.
Do not use plain water alone or alcohol base engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or anti-rust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
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 five years or 102,000 mi (170
000 km) before replacement. To prevent reducing this
extended 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, a minimum solution of 50% rec-
ommended MopartAntifreeze/ Coolant Five Year/
100,000 mi (160 934 km) Formula HOAT (Hybrid Organic
Additive Technology), or equivalent, in water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below234ÉF (237ÉC ) are anticipated.
Use only high purity water such as distilled or deionized
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.
