Where Are the Air Bags?
Driver's and passenger's front
air bags
Your vehicle is equipped with a
Advanced Supplemental Restraint
System (SRS) and lap/shoulder belts
at both the driver and passenger
seating positions.
The SRS consists of air bags which
are located in the center of the steer-
ing wheel, in the driver's side lower
crash pad below the steering wheel
column and the passenger's side
front panel pad above the glove box.
The air bags are labeled with the let-
ters "AIR BAG" embossed on the
pad covers.
The purpose of the SRS is to provide
the vehicle's driver and front passen-
gers with additional protection than
that offered by the seat belt system
alone.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 SRS Control
Module (SRSCM) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or
severity of injury in an accident.

How Does the Air Bag System
Operate?
The SRS consists of the following
components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM)/
Rollover sensor
8. Front impact sensors
9. Side impact sensors10. Side pressure sensors
11. The front passenger's seat belt
buckle sensors
12. Emergency Fastening Device
(EFD)
13. Occupant classification system
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the ignition switch is in the ON posi-
tion to determine if a crash impact is
severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
Information
The seat belt buckle sensor deter-
mines whether the front passenger's
seat belt is fastened. According to
whether the seat belt is fastened or not
and how severe the impact is, this sen-
sor provides the function to control
the SRS deployment.
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration.
The system checks the air bag elec-
trical system for malfunctions. The
light indicates that there is a potential
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.

During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration (measured in
g-force) is high enough the control
unit will inflate the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact or rollover.
Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
Air bags inflate in the event of cer-
tain frontal or side collisions 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
based upon the severity of a colli-
sion and its direction, etc. 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 vehicles
or objects which your vehicle
impacts during a 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 acci-
dent. 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 and
curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
and curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. If your SRS malfunctions, the air
bag may not inflate properly dur-
ing an accident increasing the
risk of serious injury or death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light remains illuminated
after approximately six sec-
onds.
The light comes on while the
vehicle is in motion.
The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.
WARNING

Safety system of your vehicle
Air bag collision sensors
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
Do not hit or allow any objects
to impact the locations where air
bags or sensors are installed.
Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
Do not install bumper guards
or replace the bumper with a
non-genuine HYUNDAI parts.
This may adversely affect the
collision and air bag deploy-
ment performance.
Place the ignition switch in
the LOCK/OFF or ACC posi-
tion when the vehicle is being
towed to prevent inadvertent
air bag deployment.
Have all air bag repairs conduct-
ed by an authorized HYUNDAI
dealer.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the severity, speed, or angles of
impact of the front collision.
Side and curtain air bags
Side and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the severity, speed, or
angles of impact resulting from a
side impact collision.Although the driver's and front pas-
senger's air bags are designed to
inflate only in frontal collisions, they
also may inflate in other types of col-
lisions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed to
inflate only in side impact collisions
or rollover situations, 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.

Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.

[A] : Blind spot area
[B] : Closing at high speed
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver of an approaching vehicle
in the driver's blind spot area.
The system monitors the rear area of
the vehicle and provides information
to the driver with an audible alert and
an indicator on the outer side view
mirrors.(1) Blind-Spot Collision Warning
(BCW)
The Blind-Spot Collision Warning
(BCW) range varies relative to
vehicle speed. Note that if your
vehicle is traveling much faster
than the vehicles around you, the
warning will not occur.
(2) BCW : Closing at high speed
The BCW-Closing at high speed
feature will alert you when a vehi-
cle is approaching in an adjacent
lane at a high rate of speed. If the
driver activates the turn signal
when the system detects an
oncoming vehicle, the system
sounds an audible alert.
The time of alert (warning signal)
varies according to the speed dif-
ference between you and the
approaching vehicle.
(3) RCCW (Rear Cross-Traffic
Collision Warning)
The RCCW feature monitors
approaching cross traffic from the
left and right side of the vehicle
when your vehicle is in reverse.The feature will operate when the
vehicle is moving in reverse
below about 6 mph (10 km/h). If
oncoming cross traffic is detected
a warning chime will sound. The
time of alert varies according to
the speed difference between you
and the approaching vehicle.
