The driver's seat track position sensor,
which is installed on the seat track, deter-
mines if the seat is fore or aft of a refer-
ence position. The seat belt buckle sen-
sors determine if the driver and front pas-
senger's seat belts are fastened. These
sensors provide the ability to control the
SRS deployment based on how close the
driver's seat is to the steering wheel,
whether or not the seat belts are fas-
tened, and how severe the impact is.

The advanced SRS offers the ability to
control the air bag inflation within two lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.

According to the impact severity, seating
position and seat belt usage, the SRSCM
(SRS Control Module) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or sever-
ity of injury in an accident.

Additionally, your vehicle is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the pres-
ence of a passenger in the front passen-
ger's seat and will turn off the front pas-
senger's air bag under certain condi-
tions. For more detail, see "Occupant
classification system" in this section.

WARNING

If a seat track position sensor or an
occupant classification system is
not working properly, the SRS air
bag warning light on the instrument
panel will illuminate because the
SRS air bag warning light is con-
nected with the seat track position
sensor and the occupant classifica-
tion system. If the SRS air bag
warning light does not illuminate
when the ignition switch is turned
to the ON position, remains illumi-
nated after approximately 6 sec-
onds when the ignition switch is
turned to the ON position, or if it
illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the
advanced SRS air bag system as
soon as possible.

WARNING

• Modification to the seat structure

can adversely affect the seat
track position sensor and cause
the air bag to deploy at a different
level than should be provided.

• Do not place any objects under-

neath the front seats as they
could damage the seat track
position sensor or interfere with
the occupant classification sys-
tem.

• Do not place any objects that may

cause magnetic fields near the
front seat. These may cause a
malfunction of the seat track
position sensor.
