Safety features of your vehicle

Driver's and passenger's front air
bag
Your 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.

Driver’s front air bag
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 engine start/stop
button is turned to the ON position,
remains illuminated after approxi-
mately 6 seconds when the engine
start/stop button is turned to the
ON position, or if it illuminates
while the vehicle is being driven,
have an authorized HYUNDAI deal-
er inspect the occupant classifica-
tion system and the SRS air bag
system as soon as possible.

Safety features of your vehicle
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 engine
start/stop button is turned to the
ON position, remains illuminated
after approximately 6 seconds
when the engine start/stop button
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
Curtain air bag
Curtain 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 reduce
or 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 engine
start/stop button 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.

Features of your vehicle
Immobilizer system
Your vehicle is equipped with an electron-
ic engine immobilizer system to reduce
the risk of unauthorized vehicle use.
Your immobilizer system is comprised of
a small transponder in the smart key and
electronic devices inside the vehicle.
With the immobilizer system, whenever
you turn the engine start/stop button to
the ON position by pressing the button
while carrying the smart key, it checks
and determines and verifies if the smart
key is valid or not.
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 deactivate the immobilizer sys-
tem:
Turn the engine start/stop button to the
ON position by pressing the button while
carrying the smart key.
To activate the immobilizer system:
Turn the engine start/stop button to the
OFF position. The immobilizer system
activates automatically. Without a valid
smart key for your vehicle, the engine will
not start.
CAUTION
The smart key is designed to give
you years of trouble-free use,
however it can malfunction if
exposed to moisture or static
electricity. If you are unsure how
to use or replace the battery, con-
tact an authorized HYUNDAI deal-
er.
Using the wrong battery can
cause the smart key to malfunc-
tion. Be sure to use the correct
battery.
To avoid damaging the smart key,
don't drop it, get it wet, or expose
it to heat or sunlight.
An inappropriately disposed bat-
tery can be harmful to the envi-
ronment and human health.
Dispose the battery according to
your local law(s) or regulation.
WARNING
In order to prevent theft of your vehi-
cle, do not leave spare keys any-
where in your vehicle. Your
Immobilizer password is a customer
unique password and should be
kept confidential. Do not leave this
number anywhere in your vehicle.
