caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
