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 module
4. Emergency Fastening Device
SystemThe 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
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 illu-
minate 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, have
an authorized HYUNDAI dealer
inspect the pre-tensioner seat
belts and SRS air bags as soon as
possible.
NOTICE
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-tensioners become hot and
can burn you.

Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors. (Continued)
Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
Hold the steering wheel at the
9 o'clock and 3 o'clock posi-
tions, to minimize the risk of
injuries to your hands and
arms.
Do not use any accessory
seat covers. This could reduce
or prevent the effectiveness
of the system.
Do not place any objects over
the air bag or between the air
bag and yourself. Also, do not
attach any objects around the
area the air bag inflates such
as the door, side door glass,
front and rear pillar.
(Continued)
(Continued)
Do not place any objects
between the door and the
seat. They may become dan-
gerous projectiles if the side
air bag inflates.
Do not install any accessories
on the side or near the side air
bags.
Do not put any objects
between the side airbag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
Do not cause impact to the
doors when the Engine Start/
Stop button is in the ON posi-
tion as this may cause the
side air bags to inflate.
If the seat or seat cover is
damaged, have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.

The SRSCM (Supplemental
Restraint System Control Module)
continually monitors all SRS compo-
nents while the Engine Start/Stop
button 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 (Supplement 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 elec-
trical system for malfunctions. The
light indicates that there is a potential
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.
If your SRS malfunctions, the air
bag may not inflate properly dur-
ing 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 Engine Start/Stop
button is in the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on while the
vehicle is in motion.
The light blinks when the
vehicle is in the ready ( )
mode.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.
WARNING

2-54
Safety system of your vehicle
During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration is high
enough, the control unit will inflate
the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact or rollover.
Air bags are activated (able to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON position.
Air bags inflate in the event of cer-
tain frontal or side collisions to help
protect the occupants from serious
physical injury.
Generally, air bags are designed to
inflate based upon the severity of a
collision, its direction, etc. These
two factors determine whether the
sensors produce an electronic
deployment/inflation signal. Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles
or objects which your vehicle
impacts during a collision. The
determining factors are not limited
to those mentioned above.
The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see
the air bags inflate during an acci-
dent. It is much more likely that you
will simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in certain
side collisions, vehicles equipped
with a rollover sensor, side and
curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
and curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which to
inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises
and broken bones because the
inflation speed also causes the air
bags to expand with a great deal of
force.
There are even circumstances
under which contact with the air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.

Proper seated position for OCS
If the "PASSENGER AIR BAG OFF"
indicator is on when an adult is seat-
ed in the front passenger seat, place
the Engine Start/Stop button in the
OFF position and ask the passenger
to sit properly (sitting upright with the
seat back in an upright position, cen-
tered on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the floor).
Restart the engine and have the per-
son remain in that position. This will
allow the system to detect the person
and to enable the passenger air bag.
If the "PASSENGER AIR BAG OFF"
indicator is still on, ask the passen-
ger to move to the rear seat.The "PASSENGER AIR BAG OFF"
indicator illuminates for approxi-
mately 4 seconds after the Engine
Start/Stop button is in the ON
position or after the engine is
started. If the front passenger seat
is occupied, the OCS will then
classify the front passenger after
several more seconds.
Do Not Install a Child Restraint
in the Front Passenger's Seat
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger's seat.
An inflating air bag can forcefully
strike a child or child restraint result-
ing in serious or fatal injury.
NOTICE
B990A01O
Never allow an adult passenger
to ride in the front passenger
seat when the "PASSENGER AIR
BAG OFF" indicator is illuminat-
ed. During a collision, the air bag
will not inflate if the indicator is
illuminated. Have your passen-
ger reposition himself in the
seat. If the "PASSENGER AIR
BAG OFF" indicator remains illu-
minated after the passenger
repositions himself properly and
the vehicle is restarted, have the
passenger move to the rear seat
because the air bag will not
inflate.
