Inverter coolant cap
Never remove the
engine coolant cap
and/or inverter coolant
cap or the drain plug
while the engine and
radiator are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the hybrid system off and
wait until the engine cools
down. Use extreme care when
removing the engine coolant
cap and/or inverter coolant 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 cooling sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turn-
ing counterclockwise to remove
it.
WARNING
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
Always turn off the engine
unless the vehicle has to be
inspected with the engine on.
Be cautious as the cooling fan
may operate if the negative (-)
battery terminal is not discon-
nected.
