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 seconds after
the ignition switch 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 ignition
switch is turned ON, or if it remains
illuminated after illuminating for
approximately 6 seconds, or if it illu-
minates while the vehicle is being
driven, please have an authorized
HYUNDAI dealer inspect the pre-
tensioner seat belt and SRS air bag
system as soon as possible.✽ ✽ NOTICE
Do not attempt to service or repair
the pre-tensioner seat belt system in
any manner. Do not attempt to
inspect or replace the pre-tensioner
seat belts yourself. This must be
done by an authorized HYUNDAI
dealer.
Pre-tensioners are designed to oper-
ate only one time. After activation,
pre-tensioner seat belts must be
replaced. If the pre-tensioner seat
belt must be replaced, contact an
authorized HYUNDAI dealer.
Seat belt precautions
WARNING
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
fires during a collision the pre-
tensioner becomes hot and can
burn you.
WARNING
All occupants of the vehicle
must wear their seat belts at all
times. Seat belts and child
restraints reduce the risk of
serious or fatal injuries for all
occupants in the event of a col-
lision or sudden stop. Without a
seat belt, occupants could be
shifted too close to a deploying
air bag, strike the interior struc-
ture or be thrown from the vehi-
cle. Properly worn seat belts
greatly reduce these hazards.
Even with advanced air bags,
unbelted occupants can be
severely injured by a deploying
air bag.
Always follow the precautions
about seat belts, air bags and
occupant safety contained in
this manual.

How does the air bag system
operate
Air bags are activated (able toinflate if necessary) only when the
ignition switch is changed to the
ON or START position.
Air bags inflate instantly in the event of a serious frontal or side collision
in order to help protect the occu-
pants from serious physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate based upon the severity of a
collision and its direction. These
two factors determine 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
density and stiffness of the vehi-
cles or objects which your vehicle
hits in the collision. The determin-
ing 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
simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in certain side collisions, vehicles equipped with a
rollover sensor, side impact air bags
and curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
impact air bags and curtain air bags
will remain inflated longer to help
provide protection from ejection,
especially when used in conjunction
with the seat belts.
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 col-
lision occurs and the need to inflate
the air bag between the occupant
and the vehicle structures before
the occupant impacts those struc-
tures. This speed of inflation reduces the
risk of serious or life-threatening
injuries in a severe collision 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 bro-
ken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
There are even circumstances under which contact with the
steering wheel air bag can cause
fatal injuries, especially if the
occupant is positioned exces-
sively close to the air bag.
WARNING - Air bag
inflation
Sit as far back as possible from
the steering wheel while still
maintaining comfortable control
of your vehicle. A distance of at
least 10" from your chest to the
steering wheel is recommended.
Failure to do so can result in
severe personal injuries or death
caused by a deploying air bag.

When children are seated in the
rear outboard seats of a vehicle
equipped with side and/or cur-
tain air bags, install the child
restraint system as far away
from the door side as possible.
Inflation of the side and/or cur-
tain air bags could cause seri-
ous injury or death to an infant
or child.

ger's seat only)
13. Occupant classification system (front passenger’s seat only)
14. Driver’s and front passenger’s seat belt buckle sensors
15. Anchor pretensioner assembly
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 illumi-
nate for about 6 seconds after the
ignition switch is turned to the ON
position, after which the SRS 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 immediately.
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 vehi- cle is in motion.
The light blinks continuously when the ignition switch is in ON posi-
tion. The front air bag modules are locat-
ed both in the center of the steering
wheel, in the front passenger's panel
above the glove box and/or in the dri-
ver’s side knee bolster. When the
SRSCM detects a sufficiently severe
impact to the front of the vehicle, it
will automatically deploy the front air
bags.

When an adult is seated in the front
passenger seat, if the PASSENGER
AIR BAG “OFF” indicator is on,
change the ignition switch to the 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 passenger air bag. If the PASSENGER AIR BAG “OFF”
indicator is still on, ask the passen-
ger to move to the rear seat.
✽ ✽
NOTICE
The PASSENGER AIR BAG “OFF”
indicator illuminates for about 4 sec-
onds after the ignition switch is
changed to the ON position or after
the engine is started. If the front
passenger seat is occupied, the occu-
pant classification sensor will then
classify the front passenger after
several more seconds.

WARNING - AIR BAG
"OFF" light
Do not allow an adult passenger
to ride in the front seat when the
PASSENGER AIR BAG “OFF”
indicator is illuminated,
because the air bag will not
deploy in the event of a crash.
The driver must instruct the
passenger to reposition himself
in the seat. Failure to properly
position yourself may lead to
airbag deactivation resulting in
airbag non-deployment in a col-
lision. If the PASSENGER AIR
BAG “OFF” indicator remains
illuminated after the passenger
repositions themselves proper-
ly and the vehicle is restarted, it
is recommended the passenger
move to the rear seat because
the passenger's front air bag
will not deploy.

Your vehicle is equipped with an
Advanced Supplemental Restraint
(Air Bag) System (SRS) and the
lap/shoulder belts at both the driver
and passenger seating positions.
The indications of the system's pres-
ence are the letters "AIR BAG"
embossed on the air bag pad cover
in the steering wheel and/or on the
cover of the driver's side knee bolster
located below 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, in the
knee bolster below the steering
wheel column 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
passenger with additional protection
than that offered by the seat belt sys-
tem alone in case of a frontal impact
of sufficient severity. The SRS uses
sensors to gather information about
the driver's and front passenger's
seat belt usage and impact severity. The seat belt buckle sensors deter-
mine if the driver and front passen-
ger's seat belts are fastened.
These sensors provide the ability to
control the SRS deployment based on
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 levels. A first stage level is pro-
vided for moderate-severity impacts.
A second stage level is provided for
more severe impacts.
According to the impact severity 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 sys-
tem in the front passenger's seat.
The occupant classification system
detects the presence of a passenger
in the front passenger's seat and will
turn off the front passenger's air bag
under certain conditions. For more
detail, see "Occupant classification
system" in this section.
WARNING
Do not place any objects
underneath the front seats as
they could interfere with the
occupant classification sys-
tem.
Do not place or charge an electronic device such as a
laptop computer on the front
passenger seat. Its electronic
field may cause the OCS to
switch to the "on" condition
and thus allow the passenger
air bag to deploy needlessly
in a collision, increasing your
repair costs.

Side impact air bag
Your vehicle is equipped with a side
impact air bag in each front and out-
board rear seat. The purpose of the
air bag is to provide occupants with
additional protection than that
offered by the seat belt alone.
The side impact air bags are
designed to deploy only during cer-
tain side-impact collisions, depend-
ing on the crash severity, angle,
speed and point of impact. The side
air bags are not designed to deploy
in all side impact situations or in all
rollover situations. Side impact
airbags are deployed if the rollover or
the possible rollover event is detect-
ed by ACU (Airbag Control Unit).

Why 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
expected to provide additional
protection.
These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
