SAFETY PRECAUTIONS FOR HYBRID SYSTEM (CONT.)
(Continued)
•Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system components, it
may result in electric shock.
This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the
hybrid battery system is very
dangerous and may cause
severe burns and electric
shock. This may result in seri-
ous injury or death.
•For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
•When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.
