WARNING
Do not install or place any acces-
sories (drink holder, CD or discs
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 may
be 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 illumi-
nate, or continuously remains on
after illuminating for about 6 sec-
onds when the ignition switch is
turned to the ON position, or after
the engine is started, 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 for ignition key, and turn the
engine start/stop button to the
OFF position for smart key. Never
remove or replace the air bag
related fuse(s) when the ignition
switch is in the ON position.
Failure to heed this warning will
cause the SRS air bag warning
light to illuminate.

When an adult is seated in the front pas-
senger seat, if the PASS AIR BAG “OFF”
indicator is on, turn the ignition switch to
the LOCK or 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 pas-
senger air bag.If the PASS AIR BAG "OFF" indicator is
still on, ask the passenger to move to the
rear seat.
✽ ✽
NOTICE
The PASS AIR BAG "OFF" indicator
illuminates for about 4 seconds after the
ignition switch is turned to the ON posi-
tion or after the engine is started. If the
front passenger seat is occupied, the
occupant classification sensor will then
classify the front passenger after several
more seconds.
B990A01O
WARNING
Do not allow an adult passenger to
ride in the front seat when the PASS
AIR BAG “OFF” indicator is illumi-
nated because the air bag will not
deploy in the event of a crash. If the
PASS AIR BAG "OFF" indicator
remains illuminated after the adult
passenger repositions 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.
Proper position
WARNING
Do not put a heavy load in the front
passenger seatback pocket or on the
front passenger seat. Do not hang
onto the front passenger seat. Do not
hang any items, such as a seatback
table, on the front passenger seat-
back. Do not place feet on the front
passenger seatback. Do not place
any items under the front passenger
seat. Any of these could interfere
with proper sensor operation.
WARNING
Even though your vehicle is
equipped 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.

SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light " " does not illuminate,
when you turn the ignition on, or continu-
ously 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.WARNING
Modification to SRS components
or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
Not only the modification of the
parts where the SRS sensors are
but also the modification of other
parts of the vehicle may affect the
SRS performance and lead to
possible injury.
For cleaning the air bag pad cov-
ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.

No objects should be placed over
or near the air bag modules on the
steering wheel, instrument panel,
and the front passenger's panel
above the glove box, because any
such object could cause harm if the
vehicle is in a crash severe enough
to cause the air bags to inflate.
(Continued)
(Continued)
If the air bags inflate, they must
be replaced by an authorized
HYUNDAI dealer.
Do not tamper with or disconnect
SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
If components of the air bag sys-
tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorized
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-
cedures could increase the risk
of personal injury.
If your car was flooded and has
soaked carpeting or water on the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorized HYUNDAI dealer.

KEYS (IF EQUIPPED)
WARNING- Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition switch. Children copy
adults and they could place the key
in the ignition switch. The ignition
key would enable children to oper-
ate power windows or other con-
trols, or even make the vehicle
move, which could result in serious
bodily injury or even death. Never
leave the keys in your vehicle with
unsupervised children.
WARNING
Use only HYUNDAI original parts
for the ignition key in your vehicle.
If an aftermarket key is used, the
ignition switch may not return to
ON after START. If this happens,
the starter will continue to operate
causing damage to the starter
motor and possible fire due to
excessive current in the wiring.

Immobilizer system (if equipped)
Your vehicle is equipped with an elec-
tronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.
To activate the immobilizer system:
Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
To deactivate the immobilizer sys-
tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
✽ ✽
NOTICE
When starting the engine, do not use the
key with other immobilizer keys around.
Otherwise the engine may not start or
may stop soon after it starts. Keep each
key separate in order to avoid a starting
malfunction.
✽ ✽
NOTICE
If you need additional keys or lose your
keys, consult an authorized HYUNDAI
dealer.
CAUTION
The transponder in your ignition
key is an important part of the
immobilizer system. It is designed
to give years of trouble-free service,
however you should avoid expo-
sure to moisture, static electricity
and rough handling. Immobilizer
system malfunction could occur.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
Immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave
this number anywhere in your vehi-
cle.
CAUTION
Do not change, alter or adjust the
immobilizer system because it
could cause the immobilizer sys-
tem to malfunction and should only
be serviced by an authorized
HYUNDAI dealer.
Malfunctions caused by improper
alterations, adjustments or modifi-
cations to the immobilizer system
are not covered by your vehicle
manufacturer warranty.
CAUTION
Do not put metal accessories near
the ignition switch.
Metal accessories may interrupt the
transponder signal and may pre-
vent the engine from being started.
