How does the air bags 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 assem-
blies
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor(8) Front impact sensors
(9) Side impact sensors
(10) Side Pressure sensors
The SRSCM continually monitors
SRS components while the ignition
switch is in the ON position to deter-
mine if a crash impact is severe
enough to require air bag deploy-
ment or pre-tensioner seat belt
deployment.
SRS warning light
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.
ODH033104L/Q
If your SRS malfunctions, the
air bag may not inflate properly
during 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.

During 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, at the time and with the force
needed.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot provide
adequate restraint. When needed,
the side air bags help provide protec-
tion in the event of a side impact.
• 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.
• Generally, air bags are designed to
inflate based upon the severity of a
collision it’s direction etc. 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. (Continued)
•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.
We recommend that an author-
ized HYUNDAI dealer inspect the
SRS as soon as possible if any
of these conditions 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 protec-
tion. These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehicle
indicates a collision energy absorp-
tion, and is not an indicator of whether
or not an air bag should have inflated.
Air bag collision sensors
(if equipped)
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 part. This may
adversely affect the collision
and air bag deployment per-
formance.

WARNING
(Continued)
•Place the ignition switch to
the LOCK/OFF or ACC posi-
tion, when the vehicle is being
towed to prevent inadvertent
air bag deployment.
•We recommend that all air bag
repairs are conducted 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 of impact of the front col-
lision.
.
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 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,
but they may inflate in other colli-
sions 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 front air
bag deployment would not provide
additional occupant protection.

Rear parking assist system
(if equipped)
The Rear Parking Assist System
assists the driver during reverse move-
ment of the vehicle by chiming if any
object is sensed within approximately
120 cm (50 in) 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 Parking
Assist System
Operating condition
• This system will activate when
backing up with the ignition switch
in the ON position. However, if the
vehicle speed exceeds 5 km/h (3
mph), the system may not detect
objects.
• If the vehicle speed exceeds 10
km/h (6 mph), 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.
OAD045110Sensor
•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.

Types of warning sound and indicator
• The indicator may differ from the
illustration as objects or sensors
status. If the indicator blinks, we
recommend that you have your
vehicle checked by an author-
ized HYUNDAI dealer.
• If the audible warning does not
sound or if the buzzer sounds
intermittently when shifting into R
(Reverse) position, this may indi-
cate a malfunction with the
Parking Assist System. If this
occurs, we recommend that you
have your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.
Non-operational conditions of
Parking Assist System
The Rear Parking Assist System
may not operate normally when:
• Moisture is frozen to the sensor.
• The sensor is covered with dirt or
debris such as snow or ice, or the
sensor cover is blocked.
There is a possibility of the Rear
Parking Assist System malfunction
when:
• Driving on uneven road surfaces
such as unpaved roads, gravel,
bumps, or gradient.
• Objects generating excessive noise
such as vehicle horns, loud motor-
cycle engines, or truck air brakes
can interfere with the sensor.
• Heavy rain or water spray is present.
• Wireless transmitters or mobile
phones are present near the sensor.
• The sensor is covered with snow.
• Any non-factory equipment or acces-
sories have been installed, or if the
vehicle bumper height or sensor
installation has been modified.
NOTICE
Types of warning soundIndicator
When an object is approximately
60 to 120 cm (24 to 47 in) from
the rear bumper, the warning
sound beeps intermittently.
When an object is approximately
30 to 60 cm (12 to 24 in) from
the rear bumper, the warning
sound beeps more frequently.
When an object is within approx-
imately 30 cm (12 in) from the
rear bumper, the warning sound
beeps continuously.

Detecting range may decrease when:
• Outside air temperature is extreme-
ly hot or cold.
• Undetectable objects smaller than
1 m (40 inches) and narrower than
14 cm (6 inches) in diameter.
The following objects may not be
recognized by the sensor:
• Sharp or slim objects such as
ropes, chains or small poles.
• Objects, which tend to absorb sen-
sor frequency such as clothes,
spongy material or snow.
Rear parking assist system pre-
cautions
• The rear parking assist system
may not operate consistently in
some circumstances depending on
the speed of the vehicle and the
shapes of the objects detected.
• The rear parking assist system may
malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
• The sensor may not recognize
objects less than 40 cm (15 in)
from the sensor, or it may sense an
incorrect distance. Use caution.
• When the sensor is blocked with
snow, dirt, debris, or ice, the rear
parking assist system may be inop-
erative until the snow or ice melts,
or the debris is removed. Use a
soft cloth to wipe debris away from
the sensor.
• Do not push, scratch or strike the
sensor with any hard objects that
could damage the surface of the
sensor. Sensor damage could occur.• Do not spray the sensors or its sur-
rounding area directly with a high
pressure washer. Doing so may
cause the sensors to fail to operate
normally.
Your new vehicle warranty does
not cover any accidents or dam-
age to the vehicle or injuries to
its occupants related to a Rear
Parking Assist System. Always
drive safely and cautiously.
