Component
Diesel Exhaust Fluid
NOTE:
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to
operate at colder-than-normal conditions for prolonged periods, use climatized No. 2
diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the fuel filter.
• 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.
