Recommended Engine Coolant
This vehicle has been factory filled with an Ethylene
Glycol based engine coolant with long life corrosion
inhibitors (called HOAT, for Hybrid Organic Additive
Technology). Follow the “Maintenance Schedule” for the
recommended coolant change intervals. Refer to Recom-
mended Fluids, Lubricants and Genuine Parts for correct
fluid type.
CAUTION!
• Mixing of coolants other than specified engine
coolant, may result in engine damage, and de-
crease corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
• Do not use plain water alone or alcohol base
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 coolants. Use of Propy-
lene Glycol based coolants is not recommended.
