Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact an authorized
dealer.
If the engine coolant (antifreeze) is dirty or
contains visible sediment, have an authorized
dealer clean and flush with OAT coolant
(conforming to MS.90032).
Check the engine, battery (if equipped),
intercooler (if equipped), and Motor Generator
Unit (MGU) (if equipped) coolant (antifreeze)
protection every 12 months (before the onset of
freezing weather, where applicable)...
NOTE:
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant, may result in engine
damage and may decrease corrosion protection...
