WARNING!(Continued)
•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 open a cooling system pressure cap
when the radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan may start without warning, whether the ignition
is on or off.
This vehicle is equipped with an electric cooling fan
mounted behind the radiator that starts automatically, and
may start at any time. Your vehicle may determine the fan
needs to start and to run if vehicle coolant is too hot, if the
ambient air temperature is too high, or if the vehicle is
charging and the hood is open. Even after the vehicle is
turned off, the fan may start without warning and run for
several minutes. Be aware of this if you are working in the
engine compartment. Always keep fingers and tools away
from the fan blades.
The radiator fan and surrounding components must be
serviced by your authorized dealer.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any accumula-
tion of bugs, leaves, 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 tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE: Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed to
be added to the system please contact your local autho-
rized dealer.
448 SERVICING AND MAINTENANCE

If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Electric/Battery Coolant System
These coolant systems must be serviced by your autho-
rized dealer. If the coolant level is below what is specified
on the reservoir, contact your authorized dealer for service.
These systems require the use of high purity water, such as
deionized, or distilled water, when mixing the water and
coolant (antifreeze) solution. The use of lower quality
water will reduce the amount of corrosion protection in the
cooling systems. If the coolant level of the battery coolant
system is low, the wrench warning light will be illuminated
on the instrument cluster.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine dam-
age and may decrease corrosion protection. Organic
Additive Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant (anti-
freeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as pos-
sible.
• 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 radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.

SERVICING AND MAINTENANCE 449

Adding Coolant
Your vehicle has been built with an improved coolant (OAT
coolant conforming to MS.90032) that allows extended
maintenance intervals. This coolant (antifreeze) can be
used up to ten years or 150,000 miles (240,000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same coolant
(OAT coolant conforming to MS.90032) throughout the life
of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) coolant (antifreeze) that meets
the requirements of FCA Material Standard MS.90032.
When adding coolant (antifreeze):
•We recommend using MOPAR Antifreeze/Coolant 10
Year/150,000 Mile Formula OAT (Organic Additive
Technology) that meets the requirements of FCA Mate-
rial Standard MS.90032.
• Mix a minimum solution of 50% OAT coolant that meets
the requirements of FCA Material Standard MS.90032
and deionized, or distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below 34°F
(37°C) are anticipated. •
Use only high purity water such as deionized, or dis-
tilled water when mixing the water/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 coolant (antifreeze) types is not recommended
and can result in cooling system damage. If HOAT and
OAT coolant are mixed in an emergency, have a autho-
rized dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
• Low pressure expansion bottles for power electronics
and battery cooling require a special tool for removing
the cap from the expansion bottle. For the battery
coolant bottle, it is important to not add coolant if level
is low. The vehicle should be taken to dealer for proper
servicing of the battery coolant loop if this should occur.
450 SERVICING AND MAINTENANCE

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!
•Do not open hot engine cooling system. Never add
engine coolant (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.
• Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 coolant in open contain-
ers 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 expansion bottle provides a quick visual
method for determining that the coolant level is adequate.
With the engine off and cold, the level of the coolant
(antifreeze) in the bottle should be between the “MAX” and
“MIN” lines marked on the bottle.
As long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional 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 result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) 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 expansion bottle.
• Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain coolant (antifreeze) concentration at a mini-
mum of 50% OAT coolant (conforming to MS.90032) and
deionized, or distilled water. •
Use only high purity water such as deionized, or dis-
tilled water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the cooling
system.
• Make sure that the coolant expansion 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.
• 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.
• The coolant freeze point in the battery and power
electronics loop should be checked by a dealer as a
special tool is required to remove the cap from those
expansion bottles.
• Electric/Battery coolant system must be serviced by
your authorized dealer. If the coolant level is below what
is specified on the reservoir, contact your authorized
dealer for service. These systems require the use of high

purity water such as deionized, or distilled water when
mixing the water and coolant (antifreeze) solution. The
use of lower quality water will reduce the amount of
corrosion protection in the cooling systems.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. 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.
Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
