NOTICE
• Both the driver's and front pas-
senger's pre-tensioner seat belts
may be activated in certain frontal
or side collisions.
• 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 operating condi-
tions and are not hazardous.
• Although it is harmless, the fine
dust may cause skin irritation and
should not be breathed for pro-
longed periods. Wash all exposed
skin areas thoroughly after an
accident in which the pre-tension-
er seat belts were activated.
• 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 switch has been
turned to the ON position, and
then it should turn off.WARNING
Pre-tensioners are designed
to operate only one time. After
activation, pre-tensioner seat
belts must be replaced. All
seat belts, of any type, should
always be replaced after they
have been worn during a colli-
sion.
The pre-tensioner seat belt
assembly mechanisms
become hot during activation.
Do not touch the pre-tension-
er 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-tension-
er seat belt assemblies.
Do not attempt to service or
repair the pre-tensioner seat
belt system in any manner.
(Continued)
CAUTION
If the pre-tensioner seat belt is
not working properly, this warn-
ing light will illuminate even if
there is no malfunction of the
SRS air bag. If the SRS air bag
warning light does not illumi-
nate when the ignition switch is
turned ON, or if it remains illumi-
nated after illuminating for
approximately 6 seconds, or if it
illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the pre-
tensioner seat belt and SRS air
bag system as soon as possible.

Safety features of your vehicle
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 col-
lision 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
determine whether the sensors
send out 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. Though, 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 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 get the air bag between
the occupant and the vehicle struc-
tures before the occupant impacts
those structures. This speed of
inflation reduces the risk of serious
or life-threatening injuries in a
severe collision and is thus a nec-
essary part of air bag design.
However, air bag inflation can also
cause injuries which normally can
include facial abrasions, bruises and
broken 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 air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.
WARNING
To avoid severe personal injury
or death caused by deploying
air bags in a collision, the driv-
er should sit as far back from
the steering wheel air bag as
possible (at least 10 inches
(250 mm) away). The front pas-
sengers should always move
their seats as far back as pos-
sible and sit back in their seat.
Air bags inflate instantly in the
event of collision, and passen-
gers may be injured by the air
bag expansion force if they are
not in proper position.
Air bag inflation may cause
injuries which may include
facial or bodily abrasions,
injuries from broken glasses
or burns by the air bag infla-
tion gasses.

Safety features of your vehicle
Air bag warning light
The purpose of air bag warning light
in your instrument panel is to alert
you of a potential problem with your
air bag - Supplemental Restraint
System (SRS).
When the ignition switch is turned
ON, the indicator light should illumi-
nate for approximately 6 seconds,
then go off.
SRS components and functions
The SRS consists of the following
components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side impact air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM)

(Front passenger’s seat only)
12. Driver’s and front passenger’s
seat belt buckle sensors
13. Emergency fastening device
(EFD)
14. Driver’s knee air bag module
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.
W7-147
WARNING
If any of the following condi-
tions occur, 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 igni-
tion ON.
The light stays on after illumi-
nating for approximately 6
seconds.
The light comes on while the
vehicle is in motion.
The light blinks when the igni-
tion switch is in ON position.

Safety features of your vehicle
When an adult is seated in the front
passenger seat, if the PASS AIR
BAG “OFF” indicator is on, turn the
ignition switch to the LOCK or 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 PASS AIR BAG "OFF" indicator
is still on, ask the passenger to move
to the rear seat.
✽ ✽
NOTICE
The PASS AIR BAG "OFF" indica-
tor illuminates for about 4 seconds
after the ignition 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 pas-
senger after several more seconds.
B990A01O
Proper position
WARNING
Do not hang onto the front pas-
senger seat. Do not hang any
items, such as a seatback table
or entertainment system on the
front passenger seatback. Do
not place feet on the front pas-
senger seatback. Do not place
any items under the front pas-
senger seat. Any of these could
interfere with proper sensor
operation.
WARNING - AIR BAG
"OFF" light
Do not allow an adult passenger
to ride in the front seat when the
PASS 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 repo-
sition himself in the seat.
Failure to properly position
yourself may lead to airbag
deactivation resulting in airbag
non-deployment in a collision. If
the PASS AIR BAG “OFF” indi-
cator remains illuminated after
the passenger repositions
themselves properly and the
vehicle is restarted, it is recom-
mended the passenger move to
the rear seat because the pas-
senger's front air bag will not
deploy.

Driver's and passenger's front
air bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag)
System and the lap/shoulder belts at
both the driver and passenger seat-
ing positions.
The indications of the system's pres-
ence are the letters "SRS AIR BAG"
embossed on the air bag pad cover
in the steering wheel, on the knee
bolster below the steering wheel col-
umn 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 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.

❈The actual air bags in the vehicle may differ
from the illustration.
Curtain air bag (if equipped)
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.
(Continued)
Do not use any accessory
seat covers.
Use of seat covers could
reduce or prevent the effec-
tiveness 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 dangerous projectiles
and cause injury if the supple-
mental side air bag inflates.
To prevent unexpected
deployment of the side impact
air bag that may result in per-
sonal injury, avoid impact to
the side impact sensor when
the ignition switch is on.
(Continued)(Continued)
If the seat or seat cover is
damaged, have the vehicle
checked and repaired by an
authorized HYUNDAI dealer
because your vehicle is
equipped with side impact air
bags and an occupant classi-
fication system.

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
speed impacts.

Problems may arise if the sensor
installation angles are changed
due to the deformation of the front
bumper, body or B pillars or front
door 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 bumper guards or replac-
ing a bumper with non-genuine
parts may adversely affect your
vehicle’s collision and air bag
deployment performance.
Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the intensity, speed or angles of
impact of the front collision.
WARNING - Air bag
sensors
Do not hit or allow any objects
to impact the locations where
air bags or sensors are
installed.
This may cause unexpected
air bag deployment, which
could result in serious per-
sonal 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 per-
form maintenance on or
around the air bag sensors.
Have the vehicle checked and
repaired by an authorized
HYUNDAI dealer.

Safety features of your vehicle
Side impact and curtain air bags
Side impact and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the strength, speed or
angles of impact resulting from a
side impact collision.Although the front air bags (driver’s
front and knee air bags and front
passenger’s air bags) are designed
to inflate only in frontal collisions,
they also may inflate in other types of
collisions if the front impact sensors
detect a sufficient impact. Side
impact and 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, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces 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 benefits beyond the pro-
tection of the seat belts in such col-
lisions.
