Noise and smoke from inflating air
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 deployment,
seek medical attention immediately.
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.
Occupant Classification System
(OCS)
ONX4030057ONX4030057
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.

Seats & Safety System
3-52
Main components of the Occupant
Classification System
• A detection device located within the
front passenger seat cushion.
• Electronic system to help 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 passenger air bag
system is deactivated.
• The instrument panel air bag indicator
light is interconnected with the OCS.
The OCS is designed to help 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 purpose is to help reduce the risk
of injury or death from an inflating air
bag to certain front passenger seat
occupants, such as children, by requiring
the air bag to be automatically 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 occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For smaller adults it may turn
OFF, however, if the occupant does not
sit in the seat properly (for example, by
not sitting upright, by sitting on the edge
of the seat, or by otherwise 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 overhead console
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.
Always be sure that you and all vehicle
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 thick clothes like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (for
example, notebook, satellite radio) on
the seat with inverter charging.

outgrown a child restraint system sits in the front passenger seat, the system may
recognize him/her as an adult depending upon his/her physique or sitting position.
*3 : Never install a child restraint system on the front passenger seat.
*4 : The PASSENGER AIR BAG “OFF” indicator may turn on or off when a child above 12
months to 12 years old (with or without child restraint system) sits in the front passenger
seat. This is a normal condition.

• 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 system, 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 developed 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 interfere 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 seated
in the front passenger seat, place the
Ignition switch in the 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 passenger to move to the
rear seat.
WARNING
NEVER allow an adult passenger to ride
in the front passenger seat when the
“PASSENGER AIR BAG OFF” indicator
is illuminated. During a collision, the
air bag will not inflate if the indicator
is illuminated. Have your passenger
reposition themselves in the seat. If the
“PASSENGER AIR BAG OFF” indicator
remains illuminated after the passenger
repositions themselves properly
and the vehicle is restarted, have
the passenger move to the rear seat
because the air bag will not inflate.
NOTICE
The “PASSENGER AIR BAG OFF”
indicator generally illuminates for
approximately 4 seconds after the
Engine Start/Stop button is in the ON
or START position. But, if the Engine
START/STOP button is pressed to the
ON or START position within 3 minutes
after the engine is turned OFF, the
indicator does not illuminate. 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
System on the Front Passenger’s
Seat
OHI039193NOHI039193N
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 resulting in serious
or fatal injury.
WARNING
NEVER use a rearward facing Child
Restraint on a seat protected by an
ACTIVE AIRBAG in front of it, DEATH
or SERIOUS INJURY to the CHILD can
occur.
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 protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated.
Air bag collision sensors
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 sensors. 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.
• Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
•
Place the ignition switch in theLOCK/
OFF or ACC position and wait for 3
minutes when the vehicle is being
towed to prevent inadvertent air bag
deployment.
• Have all air bag repairs are
conducted by an authorized
HYUNDAI dealer.

Air bag inflation conditions
ONX4OB031017ONX4OB031017
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
ONX4OB031018ONX4OB031018
OTM030033OTM030033
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, from a side impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate in frontal collisions, they also may
inflate in other types of collisions if the
front impact sensors detect a sufficient
impact. Side and curtain air bags are
designed to inflate in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
Also, the side and curtain air bags are
designed to inflate when a rollover
is detected by a rollover sensor. (if
equipped with rollover sensor)
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
ONX4OB031020ONX4OB031020
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.
ONX4OB031021ONX4OB031021
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.
ONX4OB031019ONX4OB031019
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags
and front center air bag may inflate
depending on the severity of impact.
ONX4OB031022ONX4OB031022
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
