Why didn’t my air bag go off in
a collision?
Air bags are not designed to inflate in
ever y 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

•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, 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,
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.

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 protection of the
seat belts.
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.
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 addi-
tional occupant protection.
However, side and curtain air bags
may inflate depending on the severity,
vehicle speed and angles of impact.

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.

Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehi-
cle structure.
SRS care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the ignition switch is in the
ON position, or continuously remains
on, we recommend that the system
be immediately inspected by an
authorized HYUNDAI dealer.
We recommend any work on the
SRS system, such as removing,
installing, repairing, or any work on
the steering wheel, the front passen-
ger's panel, front seats and roof rails
be performed by an authorized
HYUNDAI dealer. Improper handling
of the SRS system may result in seri-
ous personal injury.
OLF034058
To reduce the risk of serious
injury or death take the follow-
ing precautions:
•Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
•Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, and the front passen-
ger's panel above the glove
box.
•Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-
tem.
•We recommend that inflated
air bags be replaced by an
authorized HYUNDAI dealer.

Additional safety precautions
Passengers should not move out of
or change seats while the vehicle is
moving.A passenger who is not
wearing a seat belt during a crash or
emergency stop can be thrown
against the inside of the vehicle,
against other occupants, or be ejected
from the vehicle.
Do not use any accessories on seat
belts.Devices claiming to improve
occupant comfort or reposition the
seat belt can reduce the protection
provided by the seat belt and increase
the chance of serious injury in a crash
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
Do not place items under the front
seats.Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraint sys-
tem sensing components and wiring
harnesses.
Do not cause impact to the doors.
Impact to the doors when the ignition
switch is in the ON position may cause
the air bags to inflate.
Adding equipment to or modify-
ing your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle's frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle's air bag system.
(Continued)
•If components of the air bag
system must be discarded, or if
the vehicle must be scrapped,
certain safety precautions
must be observed. Consult an
authorized HYUNDAI dealer for
the necessary information.
Failure to follow these precau-
tions could increase the risk of
personal injury.
