CAUTION!
•Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine cool-
ant (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 Technol-
ogy (HOAT) engine coolant (antifreeze) or any “glob-
ally compatible” coolant (antifreeze). If a non-OAT
engine coolant (antifreeze) is introduced into the cool-
ing system in an emergency, the cooling system will
need to be drained, flushed, and refilled with fresh
(Continued)
CAUTION! (Continued)
OAT coolant (conforming to MS.90032), by an autho-
rized dealer as soon as possible.
•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.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.
