WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials 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 malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.To minimize the possibility of catalyst damage:•Do not shut off the engine or interrupt the ignition
when the transaxle 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 for a prolonged period.
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.

WARNING! (Continued)
•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, 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 is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). 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 the “Maintenance Schedule” in Section 8 for
proper maintenance intervals.
If the engine coolant (antifreeze) 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 engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze), may result in
engine damage and may decrease corrosion pro-
tection. If a non-HOAT engine coolant (antifreeze)
is introduced into the cooling system in an emer-
gency, it should be replaced with the specified
engine coolant (antifreeze) as soon as possible.
•Do not use water alone or alcohol based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator engine
coolant and may plug the radiator.
(Continued)
CAUTION! (Continued)
•This vehicle has not been designed for use with
Propylene Glycol based engine coolant (anti-
freeze). 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 (antifreeze) can be used up
to five years or 102,000 miles (170 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze).
380 MAINTAINING YOUR VEHICLE

When adding engine coolant (antifreeze), a minimum
solution of 50% recommended MOPARAntifreeze/
Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid
Organic Additive Technology), or equivalent, in water
should be used. Use higher concentrations (not to exceed
70%) if temperatures below34°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 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 engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant 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 bottle.
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 coolant (antifreeze) 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 scalding or injury, do not remove the pres-
sure cap while the system is hot or under pressure.

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 high
humidity accumulating on the radiator and being vapor-
ized 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 the coolant freeze point in the radiator and in
the coolant recovery bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
recovery bottle must also be protected against freez-
ing.
•If frequent engine coolant (antifreeze) additions 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) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the radiator and coolant recovery
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 also.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
