Where Are the Air Bags?
Driver’s and passenger’s frontair 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 sensors 10. Side pressure sensors
11. Driver's knee air bag module
12. Driver's seat belt buckle sensors
(if equipped)/Front passenger's
seat belt buckle sensors
13. Anchor pre-tensioner
14. Occupant classification system
The SRSCM continually monitors all
SRS components while the Engine
Start/Stop button 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.
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.
ODH033104L/Q

2-52
Safety system of your vehicleDuring a frontal collision, sensors will
detect the vehicle’s deceleration. If
the rate of deceleration 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 toinflate 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. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/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 stays on after illumi-
nating for approximately six
seconds.
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.

Why Didn’t My Air Bag Go Off
in a Collision?
Air bags are not designed to inflate in
every collision.There are certain
types of accidents in which the air bag
would not be expected to provide
additional protection. These include
rear impacts, second or third colli-
sions in multiple impact accidents, as
well as low speed impacts. Damage
to the vehicle indicates a collision
energy absorption, and is not an indi-
cator of whether or not an air bag
should have inflated.
Air bag collision sensors
2To 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.
(Continued)
(Continued)
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 and the driver’s knee
air bag 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.

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.

Rear Parking Assist System
(if equipped)
The Rear Parking Assist System
assists the driver during reverse
movement of the vehicle by chiming
if any object is sensed within the dis-
tance of 50 inches (120 cm ) behind
the vehicle.
This system is a supplemental sys-
tem that senses objects within the
range and location of the sensors, it
cannot detect objects in other areas
where sensors are not installed.
Operation of the Rear ParkingAssist System
Operating condition
This system will activate when
backing up with the ignition switch
in the ON position. However, if vehi-
cle speed exceeds 3 mph (5km/h),
the system may not detect objects.
If vehicle speed exceeds 6 mph (10 km/h), the system will not warn you
even though objects are detected.
When more than two objects are sensed at the same time, the clos-
est one will be recognized first.
OLF044062
Sensor
ALWAYS look around your vehi-
cle to make sure there are not
any objects or obstacles before
moving the vehicle in any direc-
tion to prevent a collision.
Always pay close attention
when the vehicle is driven close
to objects, particularly pedestri-
ans, and especially children.
Be aware that some objects
may not be visible on the
screen or be detected by the
sensors, due to the objects
distance, size or material, all of
which can limit the effective-
ness of the sensor.

Detecting radar
The radars are located inside of the
rear bumper.
Always keep the rear bumper clean
for the system to work properly.
Warning message
This warning message may appearwhen :
- One or both of the sensors on therear bumper is blocked by dirt or
snow or a foreign object
- Driving in rural areas where the BSD sensor does not detect
another vehicle for an extended
period of time
- When there is inclement weather such as heavy snow or rain
If any of these conditions occur, the
light on the BSD switch and the sys-
tem will turn off automatically. When the BSD cancelled warning
message is displayed in the cluster,
check to make sure that the rear
bumper is free from any dirt or snow
in the areas where the sensor is
located. Remove any dirt, snow, or
foreign material that could interfere
with the radar sensors.
After any dirt or debris is removed,
the BSD system should operate nor-
mally after about 10 minutes of driv-
ing the vehicle.
If the system still does not operate
normally have your vehicle inspected
by an authorized HYUNDAI dealer.

The Automatic Emergency Braking
(AEB) system is designed to detect
and monitor the vehicle ahead or
detect a pedestrian in the roadway
through radar signals and camera
recognition to warn the driver that a
collision is imminent, and if neces-
sary, apply emergency braking.System setting and activation
System setting
The driver can activate the AEB by
placing the ignition switch to the ON
position and by selecting 'User
Settings', 'Driving Assist', and 'AEB
(Automatic Braking System)'. The
AEB deactivates, when the driver
cancels the system setting.

Take the following precautions
when using the Automatic
Emergency Braking (AEB):
This system is only a supple-
mental system and it is not
intended to, nor does it replace
the need for extreme care and
attention of the driver. The
sensing range and objects
detectable by the sensors are
limited. Pay attention to the
road conditions at all times.
NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and is not
a collision avoidance system.
