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 sensors 10. Side pressure sensors
11. Driver’s knee air bag module
12. Driver’s and front passenger’s
seat belt buckle sensors
13. Anchor pre-tensioner
14. Occupant classification system
The SRSCM continually monitors all SRS components while the Engine
Start/Stop button 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.
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. Thelight 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.

Safety system of your vehicle
During a frontal collision, sensors will
detect the vehicle's deceleration. If
the deceleration rate (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 byresponding to frontal impacts inwhich 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 toinflate if necessary) only when the
ignition switch is in the ON posi-tion.
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. These two
factors determine whether the sen-
sors produce an electronic deploy-ment/inflation signal. Air bag deployment depends on a
number of factors including vehiclespeed, angles of impact and the
density and stiffness of the vehi-
cles 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 youwill simply see the deflated air
bags hanging out of their storage
compartments 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, especiallywhen 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 inthe 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 HYUNDAIdealer 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/OFFposition and ask the passenger to sit
properly (sitting upright with the seat
back in an upright position, centeredon 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 allowthe 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.
B990A01ONever 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 (Continued)
Do not put an electronic
device (ex. Laptop computer,
after market navigation, satel-
lite audio, video game
machine, MP3, AC inverter,
etc.) in the front passenger
seatback pocket or on the
front passenger seat.
Do not place a sitting mat on
the front passenger seat.
Do not place any items under
the front passenger seat.
Do not place sharp objects on
the front passenger seat.
These may damage the occu-
pant detection system. If theypuncture the seat cushion.
Avoid spilling liquids on the
front seat; this may cause the
OCS not to work properly.
Keep the front seat dry at alltimes.

Safety system of your vehicle
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.
Do Not Install a Child Restraintin 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
NEVER place a rear-facing or
front-facing child restraint in
the front passenger's seat of
the vehicle.
An inflating frontal air bag
could forcefully strike a child
resulting in serious injury ordeath.
Always properly restrain chil-
dren in an appropriate childrestraint in the rear seat of the
vehicle.
WARNING

Safety system of your vehicle
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 or the
Engine Start/Stop button 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, thefront passenger's panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.Improper handling of the SRS sys-
tem may result in serious personal
injury.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 vehi-
cle 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 vehi-
cle, against other occupants, or be
ejected from the vehicle.
Do not use any accessories on seat belts. Devices claiming to
improve occupant comfort or reposi-tion the seat belt can reduce the pro-
tection 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
supplemental restraint system sens-
ing 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 restraintsystem 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 but-
ton is in the ON position may cause
the air bags to inflate. Modifications to accommodate dis- abilities.
If you require modification to your
vehicle to accommodate a disability,
contact the HYUNDAI Auto Canadaat 1-888-216-2626.
Adding equipment to or modify-
ing your air bag equipped vehi- cle
If you modify your vehicle by chang-
ing your vehicle's frame, bumper sys-tem, front end or side sheet metal or
ride height, this may affect the oper-
ation of your vehicle's air bag sys-tem.
(Continued)
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 precautionscould increase the risk of per-
sonal injury.

Immobilizer System
The immobilizer system protects
your vehicle from theft. If an improp-
erly coded key (or other device) is
used, the engine’s fuel system is dis-
abled.
When the engine Start/Stop button is
in the ON position, the immobilizersystem indicator should come on
briefly, then go off. If the indicator
starts to blink, the system does not
recognize the coding of the key.
Place engine Start/Stop button to the OFF position, then place the engine
Start/Stop button to the ON positionagain.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e., key
chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally. If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
The transponder in your key is an
important part of the immobilizer
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobilizer sys-
tem malfunction could occur.
