CAUTION!(Continued)
•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 — 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.

CAUTION!(Continued)
•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 (an-
tifreeze) 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 Organic
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 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 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.
