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 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
11. Driver's knee air bag module
12. 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.
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: (Continued)
WARNING
ODH033104L/Q

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 ignition switch or the
engine Start/Stop button is in the ON
position, or continuously remains on,
have your vehicle immediately
inspected by an authorized 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 ignition
switch or 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 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.
