Safety features of your vehicle
SRS CareThe 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 componentsor 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.

3Additional safety precautions Never let passengers ride in the
cargo area or on top of a folded-
down back seat. All occupants should
sit upright, fully back in their seats with
their seat belts on and their feet on the
floor.
 Passengers should not move out of
or change seats while the vehicle is
moving. A passenger who is not wear-
ing a seat belt during a crash or emer-
gency stop can be thrown against the
inside of the vehicle, against other
occupants, or out of the vehicle.
 Each seat belt is designed to
restrain one occupant. If more than
one person uses the same seat belt,
they could be seriously injured or killed
in a collision.
 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.
 Passengers should not place hard
or sharp objects between them-
selves and the air bags. Carrying
hard or sharp objects on your lap or in
your mouth can result in injuries if an
air bag inflates. 
Keep occupants away from the air
bag covers. All occupants should sit
upright, fully back in their seats with
their seat belts on and their feet on the
floor. If occupants are too close to the
air bag covers, they could be injured if
the air bags inflate.
 Do not attach or place objects on or
near the air bag covers. Any object
attached to or placed on the front or
side air bag covers could interfere with
the proper operation of the air bags.
 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 operation
of the supplemental restraint system
sensing components and wiring har-
nesses.
 Never hold an infant or child on your
lap. The infant or child could be seri-
ously injured or killed in the event of a
crash. All infants and children should
be properly restrained in appropriate
child safety seats or seat belts in the
rear seat.
Adding equipment to or modifying
your air bag-equipped vehicleIf 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.
WARNING
 Sitting improperly or out of posi- tion can cause occupants to be
shifted too close to a deploying
air bag, strike the interior struc-
ture or be thrown from the vehicle
resulting in serious injury or
death.
 Always sit upright with the seat- back in an upright position, cen-
tered on the seat cushion with
your seat belt on, legs comfort-
ably extended and your feet on
the floor.
 Be careful not to cause impact to the doors when the ignition is
ON. The air bags may inflate.

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.

Features of your vehicle
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.
✽ ✽ NOTICEWhen 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.
✽ ✽NOTICEIf 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 designedto give years of trouble-free service, however you should avoid expo-sure to moisture, static electricity and rough handling. Immobilizersystem 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 itcould cause the immobilizer sys- tem to malfunction and should onlybe serviced by an authorized HYUNDAI dealer.
Malfunctions caused by improperalterations, adjustments or modifi-cations to the immobilizer system are not covered by your vehiclemanufacturer warranty.
CAUTION
Do not put metal accessories nearthe ignition switch.
Metal accessories may interrupt thetransponder signal and may pre- vent the engine from being started.
