What to Expect After an Air
Bag Inflates
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driver
from seeing out of the windshield or
being able to steer. Curtain air bags
may remain partially inflated for
some time after they deploy.
Noise and smoke from inflatingair bag
When the air bags inflate, they make
a loud noise and may produce
smoke and powder in the air inside of
the vehicle. This is normal and is a
result of the ignition of the air bag
inflator. After the air bag inflates, you
may feel substantial discomfort in
breathing because of the contact of
your chest with both the seat belt and
the air bag, as well as from breathing
the smoke and powder. The powder
may aggravate asthma for some
people. If you experience breathing
problems after an air bag deploy-
ment, seek medical attention imme-
diately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If
this is the case, wash and rinse with
cold water immediately and seek
medical attention if the symptoms
persist.
After an air bag inflates, take
the following precautions:
Open your windows and
doors as soon as possible
after impact to reduce pro-
longed exposure to the smoke
and powder released by the
inflating air bag.
Do not touch the air bag stor-
age area's internal compo-
nents immediately after an air
bag has inflated. The parts
that come into contact with an
inflating air bag may be very
hot.
WARNING
Always wash exposed skin
areas thoroughly with cold
and mild soap.
Always have an authorized
HYUNDAI dealer replace the
air bag immediately after
deployment. Air bags are
designed to be used only
once.

Occupant Classification
System (OCS)
Your vehicle is equipped with an
Occupant Classification System
(OCS) in the front passenger's seat.
Main components of theOccupant Classification System
A detection device located within
the front passenger seat cushion.
Electronic system to determine whether the passenger air bag
systems should be activated or
deactivated.
An indicator light located on the instrument panel which illuminates
the words "PASSENGER AIR BAG
OFF" indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag indi- cator light is interconnected with
the OCS.
The OCS is designed to detect the
presence of a properly-seated front
passenger and determine if the pas-
senger's front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the
risk of injury or death from an inflat-
ing air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automati-
cally turned OFF. For example, if a child restraint of the
type specified in the regulations is on
the seat, the occupant classification
sensor can detect it and cause the
air bag to turn OFF.
Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,
should not cause the passenger air
bag to be automatically turned OFF.
For small adults it may be turned
OFF, however, if the occupant does
not sit in the seat properly (for exam-
ple, by not sitting upright, by sitting
on the edge of the seat, or by other-
wise being out of position), this could
cause the sensor to turn the air bag
OFF.
You will find the "PASSENGER AIR
BAG OFF" indicator on the center
fascia 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 system of your vehicle
Always be sure that you and all vehi-
cle occupants are seated properly
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 if
the passenger takes actions which
can affect the classification system.
These include:
Failing to sit in an upright position.
Leaning against the door or center console.
Sitting towards the sides of the front of the seat.
Putting their legs on the dashboard or resting them on other locations
which reduce the passenger
weight on the front seat.
Wearing the seat belt improperly.
Reclining the seatback.
Wearing a thick cloth like ski wear or hip protection wear.
Putting an additional thick cushion on the seat.
Putting electrical devices (e.g. notebook, satellite radio) on the
seat with inverter charging.

Do not sit on the passen-
ger seat wearing heavily
padded clothes such as
ski wear and hip protec-
tor.
Do not use car seat
accessories such as thick
blankets and cushions
which cover up the car
seat surface.
Do not place electronic
devices such as laptops,
DVD player, or conductive
materials such as water
bottles on the passenger
seat.
Do not use electronic
devices such as laptops
and satellite radios which
use inverter chargers.
If large quantity of liquid
has been spilled on the
passenger seat, the air
bag warning light may
illuminate or malfunction.
Therefore, make sure the
seat has been completely
dried before driving the
vehicle.
Do not place sharp objects on the front passenger seat. These may damage the occupant detection sys-
tem, if they puncture the seat cushion.
Do not place any items under the front passenger seat.
When changing or replacing the seat or seat cover, use original items only. The OCS has been devel-
oped based on using original HYUNDAI car seats only. Altering or changing the authentic parts may
result in system malfunction and increase risk of injury when in collision. Any of the above could inter-
fere with the proper operation of the OCS sensor thereby increasing the risk of an injury in an accident.

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.
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 passen-
ger's seat. An inflating air bag can
forcefully strike a child or child
restraint resulting 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 illu-
minated. During a collision, the
air bag will not inflate if the indi-
cator is illuminated. Have your
passenger reposition himself in
the seat. If the "PASSENGER
AIR BAG OFF" indicator
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.

Why Didn't My Air Bag Go Off
in a Collision?
There are certain types of accidents
in which the air bag would not be
expected to provide additional pro-
tection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehi-
cle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should
have inflated.
Air bag collision sensors
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 or
death.
Always properly restrain chil-
dren in an appropriate child
restraint in the rear seat of the
vehicle.
WARNING
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 con-
ducted by an authorized
HYUNDAI dealer.

Air bag inflation conditions
Front air bags
Front air bags and the driver’s knee
air bag are designed to inflate in a
frontal collision depending on the the
severity of impact of the front colli-
sion.
Side and curtain air bags
Side and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the severity of impact
resulting from a side impact collision.Although the driver’s and front pas-
senger’s air bags are designed to
inflate only in frontal collisions, they
also may inflate in other types of col-
lisions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed to
inflate only in side impact collisions
or rollover situations, but they may
inflate in other collisions if the side
impact sensors detect a sufficient
impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.

Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags
are designed not to deploy in such
cases because they may not provide
benefits beyond the protection of the
seat belts.Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not provide
any additional benefit.
Front air bags may not inflate in side
impact collisions, because occu-
pants move in the direction of the
collision, and thus in side impacts,
front air bag deployment would not
provide additional occupant protec-
tion.
However, side and curtain air bags
may inflate depending on the severi-
ty of impact.
