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.
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.
WARNING (continued)
Do not put an electronic
device (ex. Laptop computer,
after market DMB, navigation,
satellite 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 they
puncture 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 all
times.

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 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
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

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 Engine Start/Stop but-
ton is in the ON position, or continu-
ously remains on, have your vehicle
immediately inspected by an author-
ized 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 1-877-
378-8727.
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 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.

Battery replacement
If the Smart Key is not working prop-
erly, try replacing the battery with a
new one.
Battery Type: CR2032
To replace the battery:
1. Pry open the rear cover of thesmart key.
2. Remove the old battery and insert the new battery.

HYUNDAI dealer.
Information
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
and regulation(s).
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 ignition switch is placed in
the ON position, the immobilizer sys-
tem 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 the ignition switch to the
LOCK/OFF position, then place the
ignition switch to the ON position
again.
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.
