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 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 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.

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 centerconsole.
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, cell
phone) on the seat with inverter
charging.Condition and operation in the front passenger Occupant Classification System

Do not sit on the passen-
ger seat wearing heavily
padded clothes such as
ski wear and hip protector.
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, cell phone, 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 Engine Start/Stop button in the
OFF position and ask the passenger
to sit properly (sitting upright with the
seat back in an upright position, cen-
tered on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the floor).
Restart the engine and have the per-
son 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 Engine
Start/Stop button 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 seconds.
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 passenger's seat.
An inflating air bag can forcefully
strike a child or child restraint result-
ing 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 illuminat-
ed. During a collision, the air bag
will not inflate if the indicator is
illuminated. Have your passen-
ger reposition himself in the
seat. If the "PASSENGER AIR
BAG OFF" indicator remains illu-
minated 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?
Air bags are not designed to inflate in
every 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 colli-
sions in multiple impact accidents, as
well as low speed impacts. Damage
to the vehicle indicates a collision
energy absorption, and is not an indi-
cator 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.
(Continued)
WARNING
(Continued)
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.

Safety system of your vehicle
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 occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide addi-
tional occupant protection.
However, side and curtain air bags
may inflate depending on the severi-
ty of impact.

2-60
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 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. 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 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 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.
Air Bag Warning Labels
Air bag warning labels, required by
the U.S. National Highway Traffic
Safety Administration (NHTSA), are
attached to alert the driver and pas-
sengers of potential risks of the air
bag system. Be sure to read all of the
information about the air bags that
are installed on your vehicle in this
Owners Manual.
(Continued)
•If components of the air bag
system must be discarded, or if
the vehicle must be scrapped,
certain safety precautions
must be observed. Consult an
authorized HYUNDAI dealer for
the necessary information.
Failure to follow these precau-
tions could increase the risk of
personal injury.
