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 Technology (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 authorized 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 (antifreeze) is not recommended.

facilities, factory-trained technicians, special tools, and

problem.

work done that is not on your maintenance log, let the

This is why you should always talk to an authorized  
dealer’s service manager first. If for some reason you are  
still not satisfied, talk to the general manager or owner of  
the authorized dealer. They want to know if you need  
assistance. If an authorized dealer is unable to resolve the  
concern, you may contact FCA US LLC's Customer
