Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer (if equipped) is shared. It is located
in the front of the engine compartment on the passenger
side and should be checked for fluid level at regular
intervals. Fill the reservoir with windshield washer sol-
vent (not radiator antifreeze) and operate the system for
a few seconds to flush out the residual water.
Rear Window Defroster
The pushbutton is located on
the bottom right side of the
blower control knob. Press
this button to turn on the rear
window defroster. An amber
light shows that the defroster
is on.The defroster will automatically turn off after approxi-
mately ten minutes. For an additional five minutes of
operation, press the button again. To prevent excessive
battery drain, use the defroster only when the engine is
operating.

17. Temperature Gauge
If the pointer rises to theH(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 theH(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.18. Cruise Indicator Light — If Equipped

NOTE:For maximum airflow to the rear seat passen-
gers, the center instrument panel outlets can be aimed, so
that the left center outlet is directed toward the right rear
passenger and the right center outlet is directed toward
the left rear passenger.
Fan Control
Use this control to regulate the
amount of air forced through the
system in any mode you select.
The fan speed increases as you
move the control from left (OFF)
to right.
Temperature Control
Use this control to regulate the
temperature of the air inside the
passenger compartment. The blue
area of the scale indicates cooler
temperatures while the red area
indicates warmer temperatures.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce air flow to the
condenser, reducing air conditioning performance.

•Before You Cross Any Type Of Water– As you
approach any type of water you need to determine if
you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a
stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe
crossing is the water depth, current and bottom con-
ditions. On soft bottoms the vehicle will sink in,
effectively increasing the water level on the vehicle. Be
sure to consider this when determining the depth and
the ability to safely cross•Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water– Puddles, pools, flooded or other
standing water areas normally contain murky or
muddy waters. These water types normally contain
hidden obstacles and make it difficult to determine an
accurate water depth, approach angle, and bottom
condition. Murky or muddy water holes are where
you want to hook up tow straps prior to entering. This
makes for a faster, cleaner and easier vehicle recovery.
If you are able to determine you can safely cross, than
proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effec-
tiveness by depositing debris onto the radiator.

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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H”,
pull over when safe and stop the vehicle with the
engine at idle. Turn the air conditioner OFF and wait
until the pointer drops back into the normal range.
After appropriate action has been taken, if the
pointer remains on the “H”, 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, refer to “Maintenance”, Section 7 of
this manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat indi-
cator light will come on, and the vehicle will
slow slightly until the automatic transaxle cools
down enough to allow a return to the requested speed. If
the high speed is maintained, the overheating will reoccur,
as before, in a cyclic fashion.

JUMP-STARTING PROCEDURES DUE TO A LOW
BATTERY
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 hurt by the fan.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle cannot be started this way and may be damaged.
Unburned fuel could enter the catalytic converter and
once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a discharged
battery, booster cables may be used to obtain a start
from another vehicle. This type of start can be
dangerous if done improperly, so follow this proce-
dure carefully.
340 WHAT TO DO IN EMERGENCIES

Windshield Wiper Blade Replacement
1. Lift the wiper arm away from the glass.
2. Push the release tab and slide the wiper blade assem-
bly down along the arm. Gently place the wiper arm on
the windshield.
3. Install the new blade assembly onto the wiper arm tip
until it locks in place.
Windshield Washer Fluid Reservoir
The windshield washer fluid reservoir is located in the rear
of the engine compartment on the right side and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent (not radiator antifreeze).
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.If you notice a change in the sound of the exhaust system,
or if exhaust fumes can be detected inside the vehicle or
when the underside or rear of the vehicle is damaged,
have a competent technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned 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 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!
•When 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 any time the ignition
switch is in the ON position.
•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.
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 — Drain, Flush And Refill
Refer to “Maintenance Schedule” under Section 8.
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
Refer to “Fluids, Lubricants and Genuine Parts” in Sec-
tion 8.
CAUTION!
•Mixing of coolants other than specified Hybrid
Organic Additive Technology (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.
•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.
•This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended.
366 MAINTAINING YOUR VEHICLE

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 100,000 miles
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 Addi-
tive Technology (HOAT) coolant.
When adding coolant, a minimum solution of 50% rec-
ommended MoparAntifreeze/Coolant 5 Year/100,000
Mile Formula HOAT (Hybrid Organic Additive Technol-
ogy), or equivalent, in water should be used. Use higher
concentrations (not to exceed 70%) if temperatures below

34°F (
37°C) 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.
