Seat belt precautions
WARNING
Pre-tensioners are designed to
operate only one time. After acti-
vation, pre-tensioner seat belts
must be replaced. All seat belts,
of any type, should always be
replaced after they have been
worn during a collision.
The pre-tensioner seat belt
assembly mechanisms become
hot during activation. Do not
touch the pre-tensioner seat belt
assemblies for several minutes
after they have been activated.
Do not attempt to inspect or
replace the pre-tensioner seat
belts yourself. This must be done
by an authorized HYUNDAI dealer.
Do not strike the pre-tensioner
seat belt assemblies.
Improper handling of the pre-ten-
sioner seat belt assemblies, and
failure to heed the warnings not
to strike, modify, inspect, replace,
service or repair the pre-tension-
er seat belt assemblies may lead
to improper operation or inadver-
tent activation and serious injury.
(Continued)
(Continued)
Always wear the seat belts when
driving or riding in a motor vehi-
cle.
If the vehicle or pre-tensioner
seat belt must be discarded, con-
tact an authorized HYUNDAI deal-
er.
WARNING
All occupants of the vehicle must
wear their seat belts at all times.
Seat belts and child restraints
reduce the risk of serious or fatal
injuries for all occupants in the
event of a collision or sudden stop.
Without a seat belt, occupants
could be shifted too close to a
deploying air bag, strike the interior
structure or be thrown from the
vehicle. Properly worn seat belts
greatly reduce these hazards.
Even with advanced air bags,
unbelted occupants can be severe-
ly injured by a deploying air bag.
Always follow the precautions
about seat belts, air bags and occu-
pant seating contained in this man-
ual.

SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light " " does not illuminate,
when you turn the ignition on, or continu-
ously remains on, have your vehicle
immediately inspected by an authorized
HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger's panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.WARNING
Modification to SRS components
or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
Modification of the components
where the SRS sensors are
installed and also modification of
other components of the vehicle
may affect SRS performance and
lead to possible injury.
For cleaning the air bag pad cov-
ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.

No objects should be placed over
or near the air bag modules on the
steering wheel, instrument panel,
and the front passenger's panel
above the glove box, because any
such object could cause harm if the
vehicle is in a crash severe enough
to cause the air bags to inflate.
(Continued)
(Continued)
If the air bags inflate, they must
be replaced by an authorized
HYUNDAI dealer.
Do not tamper with or disconnect
SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
If components of the air bag sys-
tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorized
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-
cedures could increase the risk
of personal injury.
If your car was flooded and has
soaked carpeting or water on the
flooring, you shouldn't try to start
the hybrid system have the car
towed to an authorized HYUNDAI
dealer.
