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 electrical 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
protection.
WARNING
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 conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.
• The light stays on after illuminating
for approximately three to 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 conditions occur.
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.
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
protection in the event of a side impact
or rollover.• Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain
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, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• 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 compartments 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 protection
from ejection, especially when used in
conjunction with the seat belts.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which 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.

Seats & Safety System
Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193NOHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
• NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
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 collisions in multiple
impact accidents, as well as low speed
impacts. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
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 sensors. 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 deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.

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
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 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.
Air bag non-inflation conditions
OCN7030051OCN7030051
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 protection of the seat belts.

OCN7030052OCN7030052
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
OCN7030049OCN7030049
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
OCN7030053OCN7030053
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.
OCN7030054OCN7030054
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 “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
