COOLANT
Inverter coolant
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level everyday. If it is near or at MIN, add enough coolant
between MIN and MAX and check the
cooling system for air bleed at an author-
ized HYUNDAI dealer.
Engine coolant
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level per every day, at the begin-
ning of the winter season, and before
traveling to a colder climate.
Checking the coolant level
CAUTION
Do not confuse the cap of engine
coolant and inverter coolant. If not, the coolant circulation problem ofengine or Hybrid system may occur because the cap pressure is different.
CAUTION
When adding coolant, be carefulnot to overfill.
WARNING
Removing radiator
cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
The engine coolant level is influ- enced by hybrid system tempera-
ture. Before filling the engine
coolant, turn the hybrid vehicle off,
fill the engine coolant carefully.
