the third Charging Indicator
Lamp will blink and high voltage
electricity will be flowing in the
vehicle. Do not touch the high
voltage electric wire (orange),
connector, and all electric com-
ponents and devices. This may
cause electric shock and lead to
injuries. Also, do not modify
your vehicle in any way. This
may affect your vehicle per-
formance and lead to an acci-
dent.

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.

WARNING

H52
If an Accident Occurs(Continued)
Using small amount of water
or fire extinguishers not
meant for electrical fires
could cause serious injury or
death from electrical shocks.
•Upon witnessing any sparks,
gases, flames, or fuel leakage
of your vehicle, immediately
call emergency services or
contact an authorized
HYUNDAI dealer. Also, advise
them that a hybrid vehicle is
involved.
SAFETY PRECAUTIONS FOR HYBRID SYSTEM (CONT.)
(Continued)

2-32
Safety system of your vehicle
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal
collisions, the pre-tensioner will acti-
vate and pull the seat belt into tighter
contact against the occupant's body.
If the system senses excessive tension
on the driver or passenger's seat belt
when the pre-tensioner system acti-
vates, the load limiter (if equipped)
inside the retractor pre-tensioner will
release some of the pressure on the
affected seat belt.
•Always wear your seat belt and
sit properly in your seat.
•Do not use the seat belt if it is
loose or twisted. A loose or
twisted seat belt will not pro-
tect you properly in an acci-
dent.
•Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
•Always replace your pre-ten-
sioners after activation or an
accident.
•NEVER inspect, service, repair
or replace the pre-tensioners
yourself. This must be done by
an authorized HYUNDAI dealer.
•Do not hit the seat belt assem-
blies.
WARNING
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioner can become hot
and can burn you.
WARNING
Body work on the front area of
the vehicle may damage the
pre-tensioner seat belt system.
Therefore, we recommend the
system to be serviced by an
authorized HYUNDAI dealer.
