Air bag warning light
The purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the warning light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
The light does not turn on briefly whenyou turn the ignition ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehicle is in motion.
SRS components and functions
The SRS consists of the following com-
ponents:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side impact 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. “PASSENGER AIR BAG OFF” indi- cator (Front passenger’s seat only) 11. Occupant classification system
(Front passenger’s seat only)
12. Driver’s and front passenger’s seat belt buckle sensors
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.
The SRS air bag warning light on the
instrument panel will illuminate for about
6 seconds after the ignition switch is
turned to the ON position, after which the
SRS air bag warning light should go out.
If any of the following conditions occurs,
this indicates a malfunction of the SRS.
Have an authorized HYUNDAI dealer
inspect the air bag system as soon as
possible.
The light does not turn on briefly when you turn the ignition ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehicle is in motion.

The front air bag modules are located
both in the center of the steering wheel
and in the front passenger's panel above
the glove box. When the SRSCM detects
a sufficiently severe impact to the front of
the vehicle, it will automatically deploy
the front air bags. Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
then allows full inflation of the air bags.
A fully inflated air bag, in combination
with a properly worn seat belt, slows the
driver's or the passenger's forward
motion, reducing the risk of head and
chest injury.
After complete inflation, the air bag
immediately starts deflating, enabling the
driver to maintain forward visibility and
the ability to steer or operate other con-
trols.

WARNING
Do not install or place any acces-sories (drink holder, cassette
holder, sticker, etc.) on the front
passenger's panel above the
glove box in a vehicle with a pas-
senger's air bag. Such objects
may become dangerous projec-
tiles and cause injury if the pas-
senger's air bag inflates.
When installing a container of liq- uid air freshener inside the vehi-
cle, do not place it near the
instrument cluster nor on the
instrument panel surface.
It may become a dangerous pro-
jectile and cause injury if the pas-
senger's air bag inflates.

Passenger’s front air bag
WARNING
If an air bag deploys, there maybe a loud noise followed by a fine
dust released in the vehicle.
These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarm
water and a mild soap after an
accident in which the air bags
were deployed.
The SRS can function only when the ignition switch is in the ON
position. If the SRS air bag warn-
ing light does not illuminate, con-
tinuously remains on after illumi-
nating for about 6 seconds when
the ignition switch is turned to
the ON position, or after the
engine is started, or comes on
while driving, the SRS is not
working properly. If this occurs,
have your vehicle immediately
inspected by an authorized
HYUNDAI dealer.

Before you replace a fuse or dis-connect a battery terminal, turn
the ignition switch to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition switch is in the ON posi-
tion. Failure to heed this warning
will cause the SRS air bag warn-
ing light to illuminate.

Occupant classification system
Your vehicle is equipped with an occu-
pant classification system in the front
passenger's seat.
The occupant classification system is
designed to detect the presence of a
properly-seated front passenger and
determine if the passenger's front air bag
should be enabled (may inflate) or not.
The driver's front air bag is not affected
or controlled by the occupant classifica-
tion system.
Main components of occupant
classification system
A detection device located within the
front passenger seat cushion.
Electronic system to determine whether the passenger air bag sys-
tems should be activated or deactivat-
ed.
A indicator light located on the instru- ment panel which illuminates the
words "PASSENGER AIR BAG OFF"
indicating the front passenger air bag
system is deactivated.
The instrument panel air bag indicator light is interconnected with the occu-
pant classification system. If the front passenger seat is occupied by
a person that the system determines to
be of adult size, and he/she sits properly
(sitting upright with the seatback in an
upright position, centered on the seat
cushion with their seat belt on, legs com-
fortably extended and their feet on the
floor), the "PASSENGER AIR BAG OFF"
indicator will turn off and the front pas-
senger's air bag will be able to inflate, if
necessary, in frontal crashes.
You will find the "PASSENGER AIR BAG
OFF" indicator on the center facia panel.
This system detects the conditions 1~4
in the following table and activates or
deactivates the front passenger air bag
based on these conditions.

Safety features of your vehicle
Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person's legs comfort-
ably extended, feet on the floor, and
wearing the seat belt properly) for the
most effective protection by the air bag
and the seat belt.
The OCS may not function properly ifthe passenger takes actions which can
defect the detection system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or resting them on other locations
which reduce the passenger weight
on the front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.Condition and operation in the front passenger occupant classification system
*1: If the front passenger seat is occu- pied by a child who is not in a CRS,
“PASSENGER AIR BAG OFF” indi-
cator may or may not be on. This is a
normal condition. But to maximize
safety, do not allow children to ride in
the front passenger seat.
*
2: Never install a child restraint system on the front passenger seat.
WARNING
Riding in an improper position or
placing weight or an active elec-
tronic device (ex. Laptop computer,
navigation etc..) on the front pas-
senger's seat when it is unoccu-
pied by a passenger adversely
affects the occupant classification
system (OCS).

Safety features of your vehicle
When an adult is seated in the front pas-
senger seat, if the “PASSENGER AIR
BAG OFF” indicator is on, turn the igni-
tion switch to the LOCK 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" indi-
cator is still on, ask the passenger to
move to the rear seat.
✽ ✽
NOTICE
The "PASSENGER AIR BAG OFF"
indicator illuminates for about 4 sec-
onds after the ignition switch is turned
to the ON position or after the engine is
started. If the front passenger seat is
occupied, the occupant classification
sensor will then classify the front pas-
senger after several more seconds.

B990A01O
WARNING
Do not allow an adult passenger to
ride in the front seat when the
“PASSENGER AIR BAG OFF” indi-
cator is illuminated because the air
bag will not deploy in the event of a
crash. If the "PASSENGER AIR BAG
OFF" indicator remains illuminated
after the adult passenger reposi-
tions themselves properly and the
car is restarted, it is recommended
that passenger move to the rear
seat because the passenger's front
air bag will not deploy.
Front seat passengers must stay
properly seated to avoid serious
injury from a deploying air bag.
WARNING
Do not put a heavy load or an active
electronic device (ex. Laptop com-
puter, navigation etc..) on the front
passenger seat. Do not place any
items under the front passenger
seat. Any of these could interfere
with proper sensor operation.

Accident statistics show that chil-
dren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recommend-
ed that child restraints be secured
in a rear seat, including an infant
riding in a rear-facing infant seat,
a child riding in a forward-facing
child seat and an older child rid-
ing in a booster seat.
Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
The occupant classification sys- tem may not work properly if
water, coffee or any other liquid
including rain gets on the seat.
Keep the front seat dry at all
times.
Do not place an electronic device such as a laptop computer on the
front passenger seat. Its elec-
tronic field may cause the OCS to
switch to the "on" condition and
thus allow the passenger air bag
to deploy needlessly in a colli-
sion, increasing your repair
costs.(Continued)
If the front passenger seat isoccupied by a child who is not in
a CRS, the "PASSENGER AIR
BAG OFF" indicator may or may
not be on and the passenger air
bag may or may not deploy in a
collision. Have the child move to a
rear seat to increase their safety.
Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
Do not place sharp objects on the front passenger seat. These may
damage the occupant classifica-
tion system, if they puncture the
seat cushion.
Do not use accessory seat cov- ers on the front seats.
(Continued)WARNING
Even though your vehicle isequipped with the occupant clas-
sification system, never install a
child restraint system in the front
passenger's seat. A deploying air
bag can forcefully strike a child
resulting in serious injuries or
death. Any child age 12 and
under should ride in the rear seat.
Children too large for child
restraints should use the avail-
able lap/shoulder belts. No mat-
ter what type of crash, children of
all ages are safer when restrained
in the rear seat.
If the "PASSENGER AIR BAG OFF" indicator is illuminated
when the front passenger's seat
is occupied by an adult and
he/she sits properly (sitting
upright with the seatback in an
upright position, centered on the
seat cushion with their seat belt
on, legs comfortably extended
and their feet on the floor), have
that person sit in the rear seat.

Safety features of your vehicle
Driver's and passenger's front air
bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) System
and lap/shoulder belts at both the driver
and passenger seating positions. The
indications of the system's presence are
the letters "AIR BAG" embossed on the
air bag pad cover in the steering wheel
and the passenger's side front panel pad
above the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel and the passenger's side
front panel above the glove box.The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt system alone in
case of a frontal impact of sufficient
severity. The SRS uses sensors to gath-
er information about the driver's and front
passenger's seat belt usage and impact
severity.

OLM039037
Driver’s front air bag
WARNING
If the occupant classification sys-
tem is not working properly, the
SRS air bag warning light on
the instrument panel will illuminate
because the passenger's front air
bag is connected with the occupant
classification system. If there is a
malfunction of the occupant classi-
fication system, the "PASSENGER
AIR BAG OFF" indicator will not
illuminate and the passenger's
front air bag will inflate in frontal
impact crashes even if there is no
occupant in the front passenger's
seat. If the SRS air bag warning
light does not illuminate when the
ignition switch is turned to the ON
position, remains illuminated after
approximately 6 seconds when the
ignition switch is turned to the ON
position, or if it illuminates while
the vehicle is being driven, have an
authorized HYUNDAI dealer inspect
the occupant classification system
and the SRS air bag system as
soon as possible.

The seat belt buckle sensors determine if
the driver and front passenger's seat
belts are fastened.
The advanced SRS offers the ability to
control the air bag inflation with two lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.
The passenger’s front air bag is designed
to help reduce the injury of children sit-
ting close to the instrument panel in low
speed collisions. However, children are
safer if they are restraint in the rear seat.
According to the impact severity and seat
belt usage, the SRSCM (SRS Control
Module) controls the air bag inflation.
Failure to properly wear seat belts can
increase the risk or severity of injury in
an accident. Additionally, your vehicle is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the pres-
ence of a passenger in the front passen-
ger's seat and will turn off the front pas-
senger's air bag under certain condi-
tions. For more detail, see "Occupant
classification system" in this section.
WARNING
If an occupant classification sys-
tem is not working properly, the
SRS air bag warning light on
the instrument panel will illuminate
because the SRS air bag warning
light is connected with the occu-
pant classification system. If the
SRS air bag warning light does not
illuminate when the ignition switch
is turned to the ON position,
remains illuminated after approxi-
mately 6 seconds when the ignition
switch is turned to the ON position,
or if it illuminates while the vehicle
is being driven, have an authorized
HYUNDAI dealer inspect the
advanced SRS air bag system as
soon as possible.

WARNING
Do not place any objects under-
neath the front seats as they could
interfere with the occupant classifi-
cation system.
