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 emissions
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 con-
nect 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:
(Continued)
WARNING! (Continued)
•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 maintenance
and repairs is highly recommended to ensure the de-
signed 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.
NOTE:Intentional tampering with emissions control
systems may void your warranty and could result in civil
penalties being assessed against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
WARNING! (Continued)
service job, take your vehicle to a competent me-
chanic.
MAINTENANCE PROCEDURES
WARNING!
Your vehicle has both a high voltage DC and AC
system as well as a 12 Volt system. DC and AC high
voltage are both extremely dangerous and can cause
severe burns, electric shock, serious injury or even
death. In order to avoid personal injuries:
•DO NOT TOUCH THE HIGH VOLTAGE CABLES
(ORANGE COLORED) AND/OR THE CONNEC-
TORS.
• Follow all Caution and Warning labels attached to
the High Voltage components.

WARNING!(Continued)
•Do not remove or replace any of the 500e System
components. All replacement or repairs of 500e
System components should be performed by a
factory-trained technician at an authorized dealer.
The pages that follow contain the requiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
(Continued)
CAUTION! (Continued)
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage them. Such
damage is not covered by the New Vehicle Limited
Warranty. If a flush is needed because of compo-
nent malfunction, use only the specified fluid for
the flushing procedure.

Power Electronics And Battery Thermal
Management Systems
The Power Electronics and Battery Thermal Management
Systems are completely separate and designed to regu-
late 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 satisfac-
tory, 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.

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, crack-
ing, 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 PRESSURE
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
