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.

WARNING
 If an air bag deploys, there maybe 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.

Safety features of your vehicle
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.
✽ ✽
NOTICEThe 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.

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.

Safety features of your vehicle
Driver's and passenger's front air
bagYour vehicle is equipped with a
Supplemental Restraint (Air Bag) System
and lap/shoulder belts at both the driver
and passenger seating positions. The
indications of the system's presence are
the letters "SRS AIR BAG" or “AIR BAG"
embossed on the air bag pad cover in the
steering wheel and the passenger's side
front panel pad above the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel and the passenger's side
front panel above the glove box.The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt system alone in
case of a frontal impact of sufficient
severity. The SRS uses sensors to gath-
er information about the driver's seat
position, the driver's and front passen-
ger's seat belt usage and impact severi-
ty.

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 passenger's front air
bag is connected with the occupant
classification system. If there is a
malfunction of the occupant classi-
fication system, the PASS AIR BAG
"OFF" indicator will not illuminate
and the passenger's front air bag
will inflate in frontal impact crashes
even if there is no occupant in the
front passenger's seat. If the SRS
air bag warning light does not illu-
minate when the ignition switch is
turned to the ON position, remains
illuminated after approximately 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 occu-
pant classification system and the
SRS air bag system as soon as
possible.

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.

Safety features of your vehicle
Side impact air bagYour vehicle is equipped with a side
impact air bag in each front seat. The
purpose of the air bag is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt alone.The side impact air bags are designed to
deploy only during certain side-impact
collisions, depending on the crash sever-
ity, angle, speed and point of impact. The
side impact air bags are not designed to
deploy in all side impact situations.
(Continued)
 Sitting improperly or out of posi-
tion can result in serious or fatal
injury in a crash. All occupants
should sit upright with the seat-
back in an upright position, cen-
tered on the seat cushion with
their seat belt on, legs comfort-
ably extended and their feet on
the floor until the vehicle is
parked and the ignition key is
removed.
 The SRS air bag system must deploy very rapidly to provide
protection in a crash. If an occu-
pant is out of position because of
not wearing a seat belt, the air
bag may forcefully contact the
occupant causing serious or fatal
injuries.

WARNING
Do not allow the passengers to lean
their heads or bodies onto doors,
put their arms on the doors, stretch
their arms out of the window, or
place objects between the doors
and passengers when they are
seated on seats equipped with side
and/or curtain air bags.

Safety features of your vehicle54

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.

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.

Safety features of your vehicle62
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.
