ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CYBERSECURITY
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should
connect equipment to the OBD II connection port
in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information. For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
REPLACEMENT PARTS
Use of genuine parts for normal/scheduled mainte-
nance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by
the use of parts which are not quality-equivalent to
genuine parts for maintenance and repairs will not be
covered by the manufacturer ’s warranty.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.

•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage
them. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Power Electronics And Battery Thermal
Management Systems
The Power Electronics and Battery Thermal Manage-
ment Systems are completely separate and designed to
regulate temperature for the high voltage battery and
the electric components.
Power Electronics And Battery Thermal
Management Systems — Coolant Level Check
The coolant expansion bottles provides a quick visual
method for determining that the coolant level is ad-
equate. With the vehicle off and coolant at ambient temperature, the level of the coolant (antifreeze) in the
bottles should be between the bottom and top lines
marked “MIN-MAX FILL RANGE”.
As long as the vehicle operating temperature is satis-
factory, the coolant bottles need only be checked once a
month.
When additional coolant (antifreeze) is needed to main-
tain the proper level, it should be added to the coolant
bottles. Do not overfill.
Coolant MIN/MAX
242 MAINTAINING YOUR VEHICLE
Page 245 of 300

Check the Power Electronics and Battery Thermal Man-
agement Systems coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable).
Maintain coolant (antifreeze) concentration at a mini-
mum of 50% Mopar Antifreeze/Coolant 10 Year/
150,000 Mile Formula OAT (Organic Additive Technol-
ogy) and distilled/deionized water for proper corrosion
protection.
Check the coolant bottles tubing for brittle rubber,
cracking, tears, cuts and tightness of the connection at
the bottles and radiator. Inspect the entire system for
leaks.
Check the front of the A/C condenser for any accumu-
lation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
NOTE:DO NOT REMOVE THE COOLANT PRES-
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
WARNING!
You or others can be badly burned by hot 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 try to open a cooling system pressure
cap when the radiator is hot.

Power Electronics And Battery Thermal
Management Systems — Cooling Pressure Caps
The caps must be fully tightened to prevent loss of
coolant (antifreeze).
The caps should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
NOTE:
•The pressure caps on the reservoirs are unique and
rated at 5 PSI caps.
• Use only Mopar replacement parts.
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety
precaution. Never add coolant (antifreeze) when
the cooling system is overheated. Do not loosen or
remove the cap to cool an overheated cooling
system. 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.
(Continued)
WARNING! (Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
vehicle damage may result.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
CAUTION!
• Mixing of coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) coolant
(antifreeze), may result in cooling system damage
and may decrease corrosion protection. Organic
Additive Technology (OAT) coolant is different
and should not be mixed with Hybrid Organic
Additive Technology (HOAT) coolant (anti-
freeze). If a non-OAT coolant (antifreeze) is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant
(antifreeze) as soon as possible.
(Continued)
244 MAINTAINING YOUR VEHICLE
Page 247 of 300

CAUTION!(Continued)
•Do not use water alone or alcohol-based coolant
(antifreeze) products. Do not use additional rust
inhibitors or antirust products, as they may not be
compatible with the radiator coolant and may
plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based coolant (antifreeze). Use
of propylene glycol-based coolant (antifreeze) is
not recommended.
Adding Coolant
Your vehicle has been built with cooling systems that
allow 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 maintenance period, it is important that
you use the same coolant (antifreeze) throughout the
life of your vehicle.
Please review these recommendations for using Or-
ganic Additive Technology (OAT) coolant (antifreeze). When adding coolant (antifreeze):
•
The manufacturer recommends using Mopar
Antifreeze/Coolant 10 Year/150,000 Mile Formula
OAT (Organic Additive Technology).
• Mix a minimum solution of 50% OAT coolant (anti-
freeze) and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below -34ºF
(-37ºC) are anticipated.
• Use only high purity water such as distilled or
deionized 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.
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 will decrease
the life of the Power Electronics and Battery Thermal
Management Systems coolant (antifreeze) and will re-
quire more frequent coolant (antifreeze) changes.

Power Electronics And Battery Thermal
Management Systems — Drain, Flush And Refill
Refer to “Maintenance Schedules” for the proper main-
tenance intervals.
If the coolant (antifreeze) is dirty or contains a consid-
erable 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 coolant (antifreeze) solution.
CAUTION!
It is recommended to have the cooling systems
serviced at your authorized dealer. Failure to do so
could result in poor cooling system performance
and/or vehicle damage.
Disposal Of Used Power Electronics And
Battery Thermal Management Systems Coolant
Used antifreeze 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
antifreeze in open containers or allow it to remain inpuddles on the ground. If ingested by a child, contact a
physician immediately. Clean up any ground spills
immediately.
Points To Remember
WARNING!
•
Turn vehicle OFF and disconnect the fan motor
lead before working near the radiator cooling fan.
• 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.
If an examination of your underhood compartment
shows no evidence of cooler or hose leaks, the vehicle
may be safely driven.
• Do not overfill the coolant recovery bottles.
