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 severi-
ty, vehicle speed and angles of
impact.

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.

Safety system of your vehicle
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 Engine Start/Stop but-
ton is in the ON position, or continu-
ously remains on, have your vehicle
immediately inspected by an author-
ized HYUNDAI dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel, the
front passenger’s panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury. 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, or 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.
Always have inflated air bags
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 Engine
Start/Stop button is in the ON position
may cause the air bags to inflate. Modifications to accommodate
disabilities.
If you require modifica-
tion to your vehicle to accommodate
a disability, contact the HYUNDAI
Customer Connect Center at 800-
633-5151.
Adding equipment to or modify- ing your air bag equipped vehi-cle
If you modify your vehicle by chang-
ing your vehicle's frame, bumper sys-
tem, front end or side sheet metal or
ride height, this may affect the oper-
ation of your vehicle's air bag sys-
tem.
(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.

Air Bag Warning Labels
OLF037059N/OLF037060N
Air bag warning labels, required by the U.S. National Highway Traffic Safety Administration (NHTSA), are attached to
alert the driver and passengers of potential risks of the air bag system. Be sure to read all of the information about the
air bags that are installed on your vehicle in this Owners Manual. Safety system of your vehicle
