Pre-tensioner seat belt
ONX4030059
Your vehicle is equipped with driver’s
and front passenger’s Pre-tensioner
Seat Belts(Retractor Pretensioner and
Emergency Fastening Device System).
The purpose of the pre-tensioner is
to make sure the seat belts fit tightly
against the occupant’s body in
certain frontal or side collision(s). The
Emergency Fastening Device System
may be activated in certain crashes
where the frontal collision(s) 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 activate and pull the seat
belt into tighter contact against the
occupant’s body.

Re
tractor Pretensioner
The purpose of the retractor pretensioner
is to make sure that the shoulder belts fit
in tightly against the occupant’s upper
body in certain frontal or side collision(s).
(2)
Emer

gency Fastening Device System
The purpose of the Emergency Fastening
Device System is to make sure that
the pelvis belts fit in tightly against the
occupant’s lower body in certain frontal
collision(s). If the system senses excessive tension
on the driver or passenger’s seat belt
when the pre-tensioner system activates,
the load limiter inside the retractor
pre-tensioner will release some of the
pressure on the affected seat belt.
WARNING
•
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 protect you properly in
an accident.
• Do not place anything near the
buckle. This may adversely affect
the buckle and cause it to function
improperly.
• Always replace your pre-tensioners
after activation or an accident.
• NEVER inspect, service, repair
or replace the pre-tensioners
yourself. We recommend that you
have the pre-tensioners inspected,
serviced, repaired or replaced by an
authorized HYUNDAI dealer.
• Do not hit the seat belt assemblies.
WARNING
Do not touch the pre-tensioner seat
belt assemblies for several minutes
after they have been activated. When
the pre-tensioner seat belt mechanism
deploys during a collision, the pre-
tensioner can become hot and can burn
you.
CAUTION
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.

NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the Engine Start/Stop
button is in the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
Information
• Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations (if
equipped with rollover sensor).
• 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 inhaled 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?
ONX4030055
The SRS consists of the following
components:
(1)
Driver's fr
ont air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Emergency fastening device system
(12) Occupant classification system
(13) Seat belt buckle sensor
The SRSCM continually monitors all SRS
components while the ignition switch
is ON to determine if a crash impact
is severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS (Supplemental Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
WARNING
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 conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.
• The light stays on after illuminating
for approximately three to six
seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
We recommend that an authorized
HYUNDAI dealer inspect the SRS
as soon as possible if any of these
conditions occur.
