Maintenance
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 at least once a year: at
the beginning of the winter season,
and before traveling to a colder cli-
mate.Checking the coolant level Turn the engine off and wait until itcools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the cool-
ing system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating, do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
The engine coolant and/or inverter
coolant level is influenced by the
hybrid system temperature. Before
checking or refilling the engine
coolant and/or inverter coolant,
turn the hybrid vehicle off.
WARNING
Removing radiator
cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal injury
from escaping hot coolant or
steam.
CAUTION - Radiator cap
Never attempt to remove theradiator cap while the engine isoperating or hot. Doing somight lead to cooling systemand engine damage.
