How Does the Air Bag 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 assemblies
6. Air bag warning light
7. SRS control module (SRSCM)/
Rollover sensor
8. Front impact sensors
9. Side impact sensors10. Side pressure sensors
11. The front passenger's seat belt
buckle sensors
12. Emergency Fastening Device
(EFD)
13. Occupant classification system
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the ignition switch is in the ON posi-
tion to determine if a crash impact is
severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
Information
The seat belt buckle sensor deter-
mines whether the front passenger's
seat belt is fastened. According to
whether the seat belt is fastened or not
and how severe the impact is, this sen-
sor provides the function to control
the SRS 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.

During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration (measured in
g-force) 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
ignition switch 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.
There is no single speed at which
the air bags will inflate. Generally,
air bags are designed to inflate
based upon the severity of a colli-
sion and 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. 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 ignition switch is in
the ON position.
The light remains illuminated
after approximately six sec-
onds.
The light comes on while the
vehicle is in motion.
The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.

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 ignition switch in the LOCK/OFF
position and ask the passenger to sit
properly (sitting upright with the seat
back in an upright position, centered
on the seat cushion with their seat
belt on, legs comfortably extended
and their feet on the floor). Restart
the engine and have the person
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 ignition
switch 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 sec-
onds.
NOTICE
B990A01O
Never allow an adult passenger
to ride in the front passenger
seat when the "PASSENGER
AIR BAG OFF" indicator is illu-
minated. During a collision, the
air bag will not inflate if the indi-
cator is illuminated. Have your
passenger reposition them-
selves in the seat. If the "PAS-
SENGER AIR BAG OFF" indica-
tor remains illuminated 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.
WARNING

Air bag collision sensors
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
Do not hit or allow any objects
to impact the locations where air
bags or sensors are installed.
Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
Do not install bumper guards
or replace the bumper with a
non-genuine HYUNDAI parts.
This may adversely affect the
collision and air bag deploy-
ment performance.
Place the ignition switch in
the LOCK/OFF or ACC posi-
tion when the vehicle is being
towed to prevent inadvertent
air bag deployment.
Have all air bag repairs conduct-
ed by an authorized HYUNDAI
dealer.
WARNING

Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehi-
cle structure.
SRS Care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the ignition switch is in the
ON position or continuously 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.
OTLE038063
To reduce the risk of serious
injury or death, take the follow-
ing precautions:
Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger's panel above the glove
box.
Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-
tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.

Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving.A passenger who is not
wearing a seat belt during a crash or
emergency stop can be thrown
against the inside of the vehicle,
against other occupants, or be ejected
from the vehicle.
Do not use any accessories on seat
belts.Devices claiming to improve
occupant comfort or reposition the
seat belt can reduce the protection
provided by the seat belt and increase
the chance of serious injury in a crash
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
Do not place items under the front
seats.Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraint sys-
tem sensing components and wiring
harnesses.
Do not cause impact to the doors.
Impact to the doors when the ignition
switch or the engine Start/Stop button
is in the ON position may cause the air
bags to inflate.Modifications to accommodate
disabilities.If you require modifica-
tion to your vehicle to accommodate
a disability, contact the HYUNDAI
Customer Connect Center at 1-800-
633-5151.
Adding equipment to or modify-
ing your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle's frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle's air bag system.
If components of the air bag
system must be discarded, or
if the vehicle must be
scrapped, certain safety pre-
cautions must be observed.
Consult an authorized
HYUNDAI dealer for the nec-
essary information. Failure to
follow these precautions
could increase the risk of per-
sonal injury.
