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.

•Make sure that the coolant control systems recovery
bottles overflow hoses are not kinked or obstructed.
• Keep the front of the coolant control systems clean. If
your vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Maintenance-Free Battery 12 Volt
Your vehicle is equipped with a maintenance-free 12 Volt
battery. You will never have to add water, nor is periodic
maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid

splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
• Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.
• The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).
