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.

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 deion-
ized water when mixing the water and coolant (anti-
freeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the
cooling systems.
Please note that it is the owners 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 consider-
able 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.

5. Lower the wiper blade and snap the pivot cap intoplace.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
underhood compartment, and the fluid level should be
checked at regular intervals. Fill the reservoir with wind-
shield washer solvent (not coolant/ antifreeze). Refer to
“Underhood Compartment” in “Maintaining Your Ve-
hicle” for further information.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly 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. Riding the brakes may also
reduce braking capacity in an emergency.
