NOTICE
• Both the driver's and front passen-
ger's pre-tensioner seat belts will be
activated in certain frontal collisions.
The pre-tensioner seat belts can be
activated where the frontal collision is
severe enough, together with the air
bags.
The pre-tensioners will not be activated
if the seat belts are not being worn at
the time of the collision. (if equipped)
• 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.CAUTION
Because the sensor that activates
the SRS air bag is connected withthe pre-tensioner seat belt, theSRS air bag warning light on theinstrument panel will illuminate for approximately 6 seconds afterthe ignition key has been turnedto the "ON" position, and then itshould turn off.
If the pre-tensioner seat belt is not working properly, this warninglight will illuminate even if there isno malfunction of the SRS air bag.If the SRS air bag warning lightdoes not illuminate when the igni-tion key is turned to "ON", or if itremains illuminated after illumi-nating for approximately 6 sec-onds, or if it illuminates while thevehicle is being driven, pleasehave an authorized Hyundai deal-er inspect the pre-tensioner seatbelt or SRS air bag system assoon as possible.WARNING
Pre-tensioners are designed to operate only one time. After acti-
vation, pre-tensioner seat belts
must be replaced. All seat belts,
of any type, should always be
replaced after they have been
worn during a collision.
The pre-tensioner seat belt assembly mechanisms become
hot during activation. Do not
touch the pre-tensioner seat belt
assemblies for several minutes
after they have been activated.
Do not attempt to inspect or replace the pre-tensioner seat
belts yourself. This must be done
by an authorized Hyundai dealer.
Do not strike the pre-tensioner seat belt assemblies.
Do not attempt to service or repair the pre-tensioner seat belt
system in any manner.

SRS components and functions
The SRS consists of the following com-
ponents:
1. Front Impact Sensors
2. “PASSENGER AIR BAG OFF”Indicator (Front passenger’s seat only)
3. SRS Air Bag Warning Light
4. Passenger's Air bag Module
5. Driver's Air Bag Module
6. SRS Control Module (SRSCM)
7. Occupant Classification System (Front passenger's seat only)
8. Driver's Seat Track Position Sensor
9. Driver's and Front Passenger's Seat Belt Buckle Sensors
10. Side Impact Sensors
11. Retractor Pre-tensioner Assemblies
12. Side Air Bag Modules
13. Curtain Air bag Modules
* : 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 malfunetion 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 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.

Safety features of your vehicle
When an adult is seated in the front pas-
senger seat, if the "PASSENGER AIR
BAG OFF" indicator is on, turn the igni-
tion key to "LOCK" and ask the passen-
ger 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" indi-
cator is still on, ask the passenger to
move to the rear seat.
✽ ✽
NOTICE
The "PASSENGER AIR BAG OFF"
indicator illuminates for about 4 sec-
onds after the ignition key 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 pas-
senger after several more seconds.

B990A01O
Proper position
WARNING
Do not allow an adult passenger to
ride in the front seat when the
“PASSENGER AIR BAG OFF” indi-
cator is illuminated, because the air
bag will not deploy in the event of a
crash. If the "PASSENGER AIR
BAG OFF" indicator remains illumi-
nated after the passenger reposi-
tions themselves properly and the
car is restarted, we recommend
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
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.

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. The driver's seat track position sensors,
which are installed on the seat track,
determine if the seat is fore or aft of a ref-
erence position. The seat belt buckle
sensors determine if the driver and front
passenger's seat belts are fastened.
These sensors provide the ability to con-
trol the SRS deployment based on how
close the driver's seat is to the steering
wheel, whether or not the seat belts are
fastened, 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
severity 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 key is turned to
the "ON" position, remains illumi-
nated after approximately 6 sec-
onds when the ignition key 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.

✽NOTICE
• Be sure to read information about the
SRS on the labels provided on the sun
visor and in the glove box.
• Advanced air bags are combined with pre-tensioner seat belts to help pro-
vide enhanced occupant protection in
frontal crashes. Front air bags are not
intended to deploy in collisions in
which sufficient protection can be
provided by the pre-tensioner seat
belt.
• If you are considering modification of your vehicle due to a disability, please
contact the Hyundai Customer
Assistance Center at 1-800-633-5151.WARNING
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with
considerable force and in the blink
of an eye. Seat belts help keep
occupants in proper position to
obtain maximum benefit from the
air bag. Even with advanced air
bags, improperly and unbelted
occupants can be severely injured
when the air bag inflates. Always
follow the precautions about seat
belts, air bags and occupant safety
contained in this manual.
To reduce the chance of serious or
fatal injuries and receive the maxi-
mum safety benefit from your
restraint system:
Never place a child in any child or
booster seat in the front seat.
ABC – Always Buckle Children in the back seat. It is the safest
place for children of any age to
ride.
Front and side air bags can injure occupants improperly positioned
in the front seats.
(Continued)
WARNING
Modification to the seat structurecan 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.

Side air bag (if equipped)
Your vehicle is equipped with a side air
bag in each front seat. The purpose of
the air bag is to provide the vehicle's driv-
er and/or the front passenger with addi-
tional protection than that offered by the
seat belt alone. 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.

OUN026109/OUN026110

B990B02LZ
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 passenger's arms and hands
should be placed on their laps.
(Continued)
(Continued)
Do not use any accessory seatcovers.
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 air bag that may
result in personal injury, avoid
impact to the side impact sensor
when the ignition key is on.
If seat or seat cover is damaged, have the vehicle checked and
repaired by an authorized
Hyundai dealer. Inform them that
your vehicle is equipped with
side air bags and an occupant
classification 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.

1JBA3513
WARNING
Do not hit or allow any objects toimpact the locations where air
bags 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.
(Continued)
(Continued)
Problems may arise if the sensorinstallation 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 vehicle’s
collision and air bag deployment
performance.

Side and/or curtain air bags
Side impact and curtain air bags are gen-
erally designed to inflate in moderate to
severe side collisions. The impact forces
measured by the side impact sensor and
SRS control module determine whether
or not to inflate the side impact air bags. Although the front air bags (driver’s and
front passenger’s air bags) are designed
to inflate only in frontal collisions, they
also may inflate in other types of colli-
sions if the front impact sensors detect a
sufficient impact. Side air bags (side
and/or curtain air bags) are designed to
inflate only in side impact collisions, but
they may inflate in other collisions if the
side impact sensors detect a sufficient
impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads
or sidewalks, air bags may deploy. Drive
carefully on unimproved roads or on sur-
faces not designed for vehicle traffic to
prevent unintended air bag deployment.
Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide occu-
pant protection beyond the protection
of the seat belts in such collisions.
