The driver's seat track position sensor,
which is installed on the seat track, deter-
mines if the seat is fore or aft of a refer-
ence position. The seat belt buckle sen-
sors determine if the driver and front pas-
senger's seat belts are fastened. These
sensors provide the ability to control the
SRS deployment based on how close the
driver's seat is to the steering wheel,
whether or not the seat belts are fas-
tened, and how severe the impact is.
The advanced SRS offers the ability to
control the air bag inflation within two lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.
According to the impact severity, seating
position and seat belt usage, the SRSCM
(SRS Control Module) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or sever-
ity of injury in an accident. Additionally, your vehicle is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the pres-
ence of a passenger in the front passen-
ger's seat and will turn off the front pas-
senger's air bag under certain condi-
tions. For more detail, see "Occupant
classification system" in this section.
WARNING
If the occupant classification sys-
tem is not working properly, the
SRS air bag warning light on the
instrument panel will illuminate
because the SRS air bag warning
light is connected with the occu-
pant classification system. If the
SRS air bag warning light does not
illuminate when the ignition switch
is turned to the ON position,
remains illuminated after approxi-
mately 6 seconds when the ignition
switch is turned to the ON position,
or if it illuminates while the vehicle
is being driven, have an authorized
HYUNDAI dealer inspect the
advanced SRS air bag system as
soon as possible.

WARNING
• Modification to the seat structure
can adversely affect the seat
track position sensor and cause
the air bag to deploy at a different
level than should be provided.
• Do not place any objects under- neath the front seats as they
could damage the seat track
position sensor or interfere with
the occupant classification sys-
tem.
• Do not place any objects that may cause magnetic fields near the
front seat. These may cause a
malfunction of the seat track
position sensor.

• Even though your vehicle is
equipped with the occupant clas-
sification system, do not install a
child restraint system in the front
passenger seat position. A child
restraint system must never be
placed in the front seat. The infant
or child could be severely injured
or killed by an air bag deployment
in case of an accident.
• Children age 12 and under must always be properly restrained in
the rear seat. Never allow chil-
dren to ride in the front passen-
ger seat. If a child over 12 must
be seated in the front seat, he or
she must be properly belted and
the seat should be moved as far
back as possible.
• For maximum safety protection in all types of crashes, all occu-
pants including the driver should
always wear their seat belts
whether or not an air bag is also
provided at their seating position
to minimize the risk of severe
injury or death in the event of a
crash. Do not sit or lean unneces-
sarily close to the air bag while
the vehicle is in motion.
(Continued)
(Continued)
• No objects should be placed overor 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 deploy.
• Never place covers, blankets or seat warmers on the passenger
seat as these may interfere with
the occupant classification sys-
tem.
• 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 deployment of the air bags
or by rendering the SRS inopera-
tive.
• If the SRS air bag warning light remains illuminated while the
vehicle is being driven, have an
authorized HYUNDAI dealer
inspect the air bag system as
soon as possible.
(Continued)
(Continued)
• Air bags can only be used once –have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
• The SRS is designed to deploy the front air bags only when an
impact is sufficiently severe and
when the impact angle is less
than 30° from the forward longitu-
dinal axis of the vehicle.
Additionally, the air bags will only
deploy once. Seat belts must be
worn at all times.
• Front air bags are not intended to deploy in side-impact, rear-
impact or rollover crashes. In
addition, front air bags will not
deploy in frontal crashes below
the deployment threshold.

Curtain air bagCurtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in cer-
tain side impact collisions.
WARNING
• The side impact air bag is sup-
plemental to the driver's and the
passenger's seat belt systems
and is not a substitute for them.
Therefore your seat belts must be
worn at all times while the vehicle
is in motion. The air bags deploy
only in certain side impact condi-
tions severe enough to cause
significant injury to the vehicle
occupants.
• For best protection from the side impact air bag system and to
avoid being injured by the
deploying side impact air bag,
both front seat occupants should
sit in an upright position with the
seat belt properly fastened. The
driver's hands should be placed
on the steering wheel at the 9:00
and 3:00 positions. The passen-
ger's arms and hands should be
placed on their laps.
• Do not use any accessory seat covers.
(Continued)
(Continued)
• Use of seat covers could reduceor prevent the effectiveness of
the system.
• Do not install any accessories on the side or near the side air bag.
• Do not place any objects over the air bag or between the air bag
and yourself.
• Do not place any objects (an umbrella, bag, etc.) between the
front door and the front seat.
Such objects may become dan-
gerous projectiles and cause
injury if the supplemental side air
bag inflates.
• To prevent unexpected deploy- ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switch
is on.
• If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags and an occupant
classification system.

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.

Features of your vehicle
Electric power steering (EPS)The power steering uses a motor to
assist you in steering the vehicle. If the
engine is off or if the power steering sys-
tem becomes inoperative, the vehicle
may still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by a power steering control unit
which senses the steering wheel torque
and vehicle speed to command the
motor.
The steering becomes heavier as the
vehicle’s speed increases and becomes
lighter as the vehicle’s speed decreases
for optimum steering control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
✽NOTICEThe following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illumi-
nate.
• The steering effort is high immediately after turning the ignition switch on.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics is completed, the steering
wheel will return to its normal condi-
tion.
• A click noise may be heard from the EPS relay after the ignition switch is
turned to the ON or LOCK position.
• A motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
• If the Electric Power Steering System does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized HYUNDAI dealer and
have the vehicle checked as soon as
possible.
• When you operate the steering wheel in low temperature, abnormal noise
could occur. If temperature rises, the
noise will disappear. This is a normal
condition.
STEERING WHEEL
CAUTION
• If the Electric Power Steering
System does not operate normal-ly, the warning light will illuminateon the instrument cluster. Thesteering wheel may become diffi-cult to control or operate abnor- mally. Take your vehicle to anauthorized HYUNDAI dealer and have the vehicle checked as soonas possible.
• When you operate the steering wheel in low temperature, abnor-mal noise could occur. If tempera-ture rises, the noise will disap-pear. This is a normal condition.
