OAC3033047R  
ing buckle.  
(1) Retractor pretensioner seat belt  
(2) EFD (Emergency Fastening Device)  
system (Driver only, if equipped)  
When it is released, the belt should  
automatically draw back into the retrac-  
tor. If this does not happen, check the  
belt to be sure it is not twisted, then try  
again.  
Your vehicle is equipped with driver’s  
and front passenger’s and rear left side  
and right side passenger’s pre-tension-  
er seat belts (Retractor Pre-tensioner)  
and EFD (Emergency Fastening  
Device)).  
Rear centre seat belt  
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 pre-ten-  
sioner seat belts may be activated in  
crashes where the frontal or side  
collision(s) is severe enough, together  
with the airbags.  
When the vehicle stops suddenly, or if  
the occupant tries to lean forward too  
quickly, the seat belt retractor will lock  
into position.  
OAC3039044TU  
When using the rear centre seat belt,  
the buckle with the “CENTER” mark  
must be used.  
WARNING  
Information  
i
Make sure that the seatback is  
locked in place when using the rear  
center seat belt.  
If you are not able to pull out the safety  
belt from the retractor, firmly pull the  
belt out and release it. After release,  
you will be able to pull the belt out  
smoothly.  
If not, the seatback may move when  
there is a sudden stop or collision,  
which could result in serious injury.

In certain frontal collisions, the preten-  
sioner will activate and pull the seat belt  
into tighter contact against the occu-  
pant’s body.  
WARNING  
• Always wear your seat belt and sit  
properly in your seat.  
- Retractor Pretensioner  
• Do not use the seat belt if it is  
loose or twisted. A loose or twist-  
ed seat belt will not protect you  
properly in an accident.  
The purpose of the retractor preten-  
sioner is to make sure that the shoul-  
der belts fit in tightly against the occu-  
pant’s upper body in certain frontal or  
side collision(s).  
• Do not place anything near the  
buckle. This may adversely affect  
the buckle and cause it to function  
improperly.  
- EFD (Emergency Fastening Device)  
The purpose of the EFD is to make  
sure that the pelvis belts fit in tightly  
against the occupant’s lower body in  
certain frontal or side collisions. (if  
equipped, Driver only)  
If the system senses excessive tension  
on the driver or passenger’s seat belt  
when the pre-tensioner system acti-  
vates, the load limiter inside the retrac-  
tor pre-tensioner will release some of  
the pressure on the affected seat belt.  
• Always replace your pre-tension-  
ers after activation or an accident.  
• NEVER inspect, service, repair or  
replace the pre-tensioners by  
yourself. We recommend that you  
have the pre-tensioners inspected,  
serviced, repaired or replaced by a  
HYUNDAI authorised repairer.  
• Do not hit the seat belt assemblies.  
WARNING  
CAUTION  
Do not touch the pre-tensioner seat  
belt assemblies for several minutes  
after they have been activated. When  
the pre-tensioner seat belt mecha-  
nism deploys during a collision, the  
pre-tensioner can become hot and  
can burn you.  
If equipped with rollover sensor  
The pre-tensioner will activate not  
only in a frontal collision but also in  
a side collision or rollover, if the  
vehicle is equipped with a side or  
curtain airbag.  
CAUTION  
CAUTION  
Body work on the front area of the  
vehicle may damage the pre-ten-  
sioner seat belt system. Therefore,  
we recommend that the system be  
serviced by a HYUNDAI authorised  
repairer.  
Without rollover sensor  
The pre-tensioner will activate not  
only in a frontal collision but also in  
a side collision, if the vehicle is  
equipped with a side or curtain air-  
bag.

The Pre-Tensioner Seat Belt System  
consists mainly of the following compo-  
nents. Their locations are shown in the  
illustration above:  
(5) Rear retractor pre-tensioner  
assembly (if equipped)  
NOTICE  
(1) SRS airbag warning light  
The sensor that activates the SRS  
airbag is connected with the pre–  
tensioner seat belts. The SRS airbag  
warning light on the instrument pan-  
el will illuminate for about 6 seconds  
after the ignition switch is placed to  
the ON position, and then it should  
turn off.  
(2) Front retractor pre-tensioner  
assembly (if equipped)  
(3) SRS control module  
(4) Emergency fastening device(EFD)  
(Driver only, if equipped)  
If the pre-tensioner is not working  
properly, the warning light will illu-  
minate even if the SRS airbag is not  
malfunctioning. If the warning light  
does not illuminate, stays illuminat-  
ed or illuminates when the vehicle is  
being driven, we recommend the  
pre-tensioner seat belts and/or SRS  
airbags be inspected by a HYUNDAI  
authorised repairer as soon as pos-  
sible.
