CAUTION!
Mixing of engine coolant (antifreeze) other

than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may
result in engine damage and may decrease
corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and
should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant
(antifreeze) or any "globally compatible"
coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) 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 MS.90032), by an autho-
rized dealer as soon as possible.
CAUTION! (Continued)
Do not use water alone or alcohol-based

engine coolant (antifreeze) 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 radiator.
