Pre-tensioner seat belt
(Driver and front passenger,
if equipped)
Your vehicle is equipped with driver's
and front passenger's Pre-tensioner
Seat Belts. The purpose of the pre-
tensioner is to make sure the seat
belts fit tightly against the occupant's
body in certain frontal collisions. The
pre-tensioner seat belts may be acti-
vated in crashes where the frontal col-
lision is severe enough, together with
the air bags.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.
ODH033058
•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.

WARNING
(Continued)
•Do not hit the seat belt assem-
blies.
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 that
the system be serviced by an
authorized HYUNDAI dealer.

Safety system of your vehicle
The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
(1) SRS air bag warning light
(2) Retractor pre-tensioner
(3) SRS control moduleThe sensor that activates the SRS
air bag is connected with the
pre–tensioner seat belts. The SRS
air bag warning light on the instru-
ment panel will illuminate for
approximately 6 seconds after the
ignition switch is placed to the ON
position, and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate even if the SRS air bag is
not malfunctioning. If the warning
light does not illuminate, stays illu-
minated or illuminates when the
vehicle is being driven, we recom-
mend the pre-tensioner seat belts
and/or SRS air bags be inspected
by an authorized HYUNDAI dealer
as soon as possible.• Both the driver's and front pas-
senger's pre-tensioner seat
belts may be activated in certain
frontal or side collisions.
• The pre-tensioners will be acti-
vated even if the seat belts are
not worn at the time of the colli-
sion.
• When the pre-tensioner seat
belts are activated, a loud noise
may be heard and fine dust,
which may appear to be smoke,
may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
• Although it is non-toxic, the fine
dust may cause skin irritation
and should not be breathed for
prolonged periods. Wash all
exposed skin areas thoroughly
after an accident in which the
pre-tensioner seat belts were
activated.

How does the air bags system
operate?
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner assem-
blies
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor(8) Front impact sensors
(9) Side impact sensors
(10) Side Pressure sensors
The SRSCM continually monitors
SRS components while the ignition
switch is in the ON position to deter-
mine if a crash impact is severe
enough to require air bag deploy-
ment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS air bag warning light on the
instrument panel will illuminate for
about 6 seconds after the ignition
switch is turned to the ON position,
after which the air bag warning light
should go out.
ODH033104L/Q
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
•The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
