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 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.
CAUTION
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 illumi-
nate for approximately 6 seconds
after the ignition key has been
turned to the "ON" position, and
then it should turn off.
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 igni-
tion key is turned to "ON", or if it
remains illuminated after illumi-
nating for approximately 6 sec-
onds, or if it illuminates while the
vehicle is being driven, please
have an authorized Hyundai deal-
er inspect the pre-tensioner seat
belt or SRS air bag system as
soon as possible.

BAG
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 functionsThe 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 equippedThe 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.
✽ ✽
NOTICEThe "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.

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.

Safety features of your vehicle40 3The 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.

Passenger’s front air bag
WARNING
If a seat track position sensor or an
occupant classification system is
not working properly, the SRS air
bag warning light on the instru-
ment panel will illuminate because
the SRS air bag warning light is
connected with the seat track posi-
tion sensor and the occupant clas-
sification 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 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 vehicle44 3Side 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)
Do not use any accessory seat
covers.
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.

Safety features of your vehicle46 3Why didn’t my air bag go off in a
collision? (Inflation and non-infla-
tion conditions of the air bag)There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.
