64 SERVICING AND MAINTENANCE
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine or electrical system damage. If
any coolant is needed to be added to the system please
contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
Organic Additive Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Electric/Battery Coolant System
These coolant systems must be serviced by an authorized
dealer. If the coolant level is below what is specified on the
reservoir, contact an authorized dealer for service.
These systems require the use of high purity water, such
as deionized, or distilled 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. If the coolant level of the battery coolant
system is low, the Hybrid Electric Vehicle System Service
Light will be illuminated on the instrument cluster.
Selection Of Coolant
NOTE:
 Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro-
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant or any "globally
compatible" coolant. If a non-OAT engine coolant is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
and refilled with fresh OAT coolant (conforming to
Ú page 59.
MS.90032), by an authorized dealer as soon as
possible.
 Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust inhibitors
or antirust products, as they may not be compatible
with the radiator engine coolant and may plug the radi-
ator.
 This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not recom-
mended.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact an
authorized dealer.
Adding Coolant
Your vehicle has been built with an improved coolant (OAT
coolant conforming to MS.90032) that allows 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 (OAT coolant conforming to MS.90032)
throughout the life of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) coolant that meets the
requirements of the manufacturer Material Standard
MS.90032. When adding coolant:
 We recommend using Mopar® Antifreeze/Coolant
10 Year/150,000 Mile (240,000 km) Formula OAT
that meets the requirements of the manufacturer
Material Standard MS.90032.
 Mix a minimum solution of 50% OAT coolant that meets
the requirements of the manufacturer Material
Standard MS.90032 and deionized, or distilled water.
Use higher concentrations (not to exceed 70%) if
temperatures below −34°F (−37°C) are anticipated.
CAUTION!
Use only high purity water such as deionized, or distilled
water when mixing the water/ coolant (antifreeze)
solution for the engine, battery or high voltage
electronics cooling systems. The use of lower quality
water will reduce the amount of corrosion protection in
the engine cooling system.
