■ When cleaning the air intake vent
● Do not use water or other liquids to
clean the air intake vent. If water is
applied to the hybrid battery (traction
battery) or other components, a mal-
function or fire may occur.
● Before cleaning the air intake vents,
make sure to turn the power switch off
to stop the hybrid system.
● Do not put a hand or leg in the air
intake vent. If it is caught in a cooling
fan, or if it touches a high voltage part
that results in an electric shock, death
or serious injuries may result.
