NOTICE
• Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal collisions.
The pre-tensioners will not be activat-
ed if the seat belts are not being worn
at the time of the collision.
• When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal oper-
ating conditions and are not haz-
ardous.
• Although it is harmless, the fine dust
may cause skin irritation and should
not be breathed for prolonged peri-
ods. Wash all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were activat-
ed.
✽ ✽
NOTICE
Because the sensor that activates the
SRS air bag is connected with the pre-
tensioner seat belt, the SRS air bag
warning light on the instrument panel
will illuminate for approximately 6 sec-
onds after the ignition switch has been
turned to the "ON" position, and then it
should turn off.WARNING
To obtain maximum benefit from a
pre-tensioner seat belt:
1. The seatbelt must be worn cor-
rectly and adjusted to the proper
position. Please read and follow
all of the important information
and precautions about your vehi-
cle’s occupant safety features –
including seat belts and air bags
– that are provided in this manu-
al.
2. Be sure you and your passen-
gers always wear seat belts prop-
erly.
CAUTION
If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no
malfunction of the SRS air bag. If
the SRS air bag warning light does
not illuminate when the ignition
switch is turned to ON, or if it
remains illuminated after illuminat-
ing for approximately 6 seconds, or
if it illuminates while the vehicle is
being driven, please have an
authorized HYUNDAI dealer inspect
the pre-tensioner seat belt or SRS
air bag system as soon as possible.

How does the air bag system
operate
Air bags are activated (able to inflate if
necessary) only when the ignition
switch is turned to the ON or START
position.
Air bags inflate instantly in the event of
serious frontal or side collision (if
equipped with side air bag or curtain
air bag) in order to help protect the
occupants from serious physical injury.
There is no single speed at which the
air bags will inflate.
Generally, air bags are designed to
inflate by the severity of a collision and
its direction. These two factors deter-
mine whether the sensors produce an
electronic deployment/inflation signal.
Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. The determining factors are
not limited to those mentioned above.
The front air bags will completely
inflate and deflate in an instant.It is virtually impossible for you to see
the air bags inflate during an accident.
It is much more likely that you will sim-
ply see the deflated air bags hanging
out of their storage compartments after
the collision.
In order to help provide protection in a
severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to inflate the air
bag between the occupant and the
vehicle structures before the occupant
impacts those structures. This speed of
inflation reduces the risk of serious or
life-threatening injuries in a severe col-
lision and is thus a necessary part of air
bag design.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bones,
because the inflation speed also caus-
es the air bags to expand with a great
deal of force.
There are even circumstances
under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close to
the steering wheel.
WARNING
To avoid severe personal injury
or death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 10 inches (250 mm)
away). The front passenger
should always move their seat as
far back as possible and sit back
in their seat.
Air bag inflates instantly in the
event of collision, passengers
may be injured by the air bag
expansion force if they are not in
proper position.
Air bag inflation may cause
injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

(Front passenger’s seat only)
WARNING
Extreme Hazard! Do not use a
rearward facing child restraint on
a seat protected by an air bag in
front of it!
Never put a child restraint in the
front passenger’s seat. If the front
passenger air bag inflates, it can
cause serious or fatal injuries.
When children are seated in the
rear outboard seats of a vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,

*: if equipped
The SRSCM continually monitors all
SRS components while the ignition
switch is ON to determine if a crash
impact is severe enough to require air
bag deployment or pre-tensioner seat
belt deployment.
The SRS air bag warning light on the
instrument panel will illuminate for about
6 seconds after the ignition switch is
turned to the ON position, after which the
air bag warning light should go out.
If any of the following conditions occurs,
this indicates a malfunction of the SRS.
Have an authorized HYUNDAI dealer
inspect the air bag system as soon as
possible.
The light does not turn on briefly when
you turn the ignition ON.
The light stays on after illuminating for
approximately 6 seconds.
The light comes on while the vehicle is
in motion.The front air bag modules are located
both in the center of the steering wheel
and in the front passenger's panel above
the glove box. When the SRSCM detects
a sufficiently severe impact to the front of
the vehicle, it will automatically deploy
the front air bags.Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
then allows full inflation of the air bags.

Safety features of your vehicle
When an adult is seated in the front pas-
senger seat, if the “PASSENGER AIR
BAG OFF” or “PASS AIR BAG OFF” indi-
cator is on, turn the ignition switch to the
LOCK 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 passenger air
bag.If the “PASSENGER AIR BAG OFF” or
“PASS AIR BAG OFF” indicator is still on,
ask the passenger to move to the rear
seat.
✽ ✽
NOTICE
The “PASSENGER AIR BAG OFF” or
“PASS AIR BAG OFF” indicator illumi-
nates for about 4 seconds after the igni-
tion switch is turned to the ON position
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
“PASSENGER AIR BAG OFF” or
“PASS AIR BAG OFF” indicator is
illuminated because the air bag will
not deploy in the event of a crash. If
the “PASSENGER AIR BAG OFF” or
“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.
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 passen-
ger seatback. 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 opera-
tion.

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" 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.
OFD037016 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 “PASSENGER
AIR BAG OFF” or “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 with 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 a seat track position sensor or an
occupant classification system is
not working properly, the SRS air
bag warning light on the instrument
panel will illuminate because the
SRS air bag warning light is con-
nected with the seat track position
sensor and the occupant classifica-
tion system. If the SRS air bag
warning light does not illuminate
when the ignition switch is turned
to the ON position, remains illumi-
nated after approximately 6 sec-
onds 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.

The side air bags are designed to deploy
only during certain side-impact collisions,
depending on the crash severity, angle,
speed and point of impact. The side air
bags are not designed to deploy in all
side impact situations.(Continued)
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 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.WARNING
The side air bag is supplemental
to the driver's and the passen-
ger'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 conditions
severe enough to cause signifi-
cant injury to the vehicle occu-
pants.
For best protection from the side
air bag system and to avoid being
injured by the deploying side air
bag, both front seat occupants
should sit in an upright position
with the seat belt properly fas-
tened. The driver's hands should
be placed on the steering wheel
at the 9:00 and 3:00 positions.
The passengers’ arms and hands
should be placed on their laps.
Do not use any accessory seat
covers.
Use of seat covers could reduce
or prevent the effectiveness of
the system.

Why didn’t my air bag go off in a
collision? (Air bags are not
designed to inflate in every colli-
sion)
There are certain types of accidents in
which the air bag would not be expect-
ed to provide additional protection to
the vehicle’s occupants.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. Damage to the vehicle indi-
cates collision energy absorption, and
is not an indicator of whether or not
an air bag should have inflated.

Air bag inflation conditions
Front air bag
Front air bags are generally designed to
inflate in moderate to severe frontal colli-
sions within a limited range of angles.
The impact forces measured by the front
impact sensor and SRS control module
determine whether or not to inflate the
front air bags.
OED036096
WARNING
Do not hit or allow any objects to
impact the locations where air bag
or sensors are installed.
This may cause unexpected air
bag deployment, which could
result in serious personal injury
or death.
If the installation location or
angle of the sensors is altered in
any way, the air bags may deploy
when they should not or they may
not deploy when they should,
causing severe injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. Have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.

Problems may arise if the sensor
installation angles are changed
due to the deformation of the
front bumper, body or B pillar
where side collision sensors are
installed. Have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.
Your vehicle has been designed
to absorb impact and deploy the
air bag(s) in certain collisions.
Installing aftermarket bumper
guards or replacing a bumper
with non-genuine parts may
adversely affect your vehicles
collision and air bag deployment
performance.
