2010 Hyundai Sonata Owner's Manual

1FEATURES OF YOUR HYUNDAI36
The SRS uses sensors to gather informa-
tion about the driver's and front passenger's
seat position, the driver's and front
passenger's seat belt usage and impact
severity.
The driver's and front passenger's seat
track position sensors, which are installed
on the seat track, determine if the seats are
fore or aft of a reference position. The seat
belt buckle sensors determine if the driver
and front passenger'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, how close the passenger's seat is
to the instrument panel, whether or not the
seat belts are fastened, and how severe
the impact is.
The advanced SRS offers the ability to
control the airbag inflation with two levels.
A first stage level is provided for moderate-
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
airbag inflation. Failure to properly wear
seat belts can increase the risk or severity
of injury in an accident.
CAUTION:
If a seat track position sensor or an
occupant classification system is not
working properly, the SRS airbag warn-
ing light
on the instrument panel will
illuminate because the SRS airbag warn-
ing light is connected with the seat track
position sensor and the occupant clas-
sification system. If the SRS airbag warn-
ing light does not illuminate when the
ignition key is turned to the "ON" posi-
tion, remains illuminated after approxi-
mately 6 seconds when the ignition key
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 airbag
system as soon as possible.
!
Additionally, your Hyundai is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the presence
of a passenger in the front passenger's
seat and will turn off the front passenger's
airbag under certain conditions. For more
detail, see "Occupant Classification Sys-
tem" later in this section.
B240A03NF-AATDriver's and Passenger's Front
AirbagYour Hyundai is equipped with an ad-
vanced Supplemental Restraint (Air bag)
System and lap/shoulder belts at both the
driver and passenger seating positions.
The indications of the system's presence
are the letters "SRS AIRBAG" embossed
on the airbag pad cover in the steering
wheel and the passenger's side front panel
pad above the glove box.
The Hyundai SRS consists of airbags
installed under the pad covers in the center
of the steering wheel and the passenger's
side front panel above the glove box.
The purpose of the SRS is to provide the
vehicle's driver and/or the front passenger
with additional protection than that offered
by the seat belt system alone in case of a
frontal impact of sufficient severity.Driver's Front Airbag

WARNING:
Always use seat belts and child restraints
– every trip, every time, everyone!
Airbags inflate with considerable force
and in the blink of an eye. Seat belts help
keep occupants in proper position to
obtain maximum benefit from the airbag.
Even with advanced airbags, improperly
belted and unbelted occupants can be
severely injured when the airbag inflates.
Always follow the precautions about seat
belts, airbags and occupant safety
contained in this manual.
To reduce the chance of serious or fatal
injuries and receive the maximum safety
benefit from your restraint system:
o Never place a child in any child or
booster seat in the front seat (see
child restraints 1-27).
o ABC – Always Buckle Children in the
back seat. It is the safest place for
children of any age to ride.
o Front and side impact airbags can
injure occupants improperly
positioned in the front seats.
o Move your seat as far back as
practical from the front airbags, while
still maintaining control of the vehicle.
o Never sit or lean unnecessarily close
to the front or side airbags.
!
WARNING:
o Modification to the seat structure can
adversely affect the seat track position
sensor and cause the airbag to deploy
at a different level than should be pro-
vided.
o Do not place any objects underneath
the front seats as they could damage
the seat track position sensor or
interfere with the occupant classifica-
tion system.
o 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.NOTE:o Be sure to read information about the
SRS on the labels provided on the back-
side of the sun visor.
o Advanced airbags are combined with
pre-tensioner seat belts to help provide
enhanced occupant protection in frontal
crashes. Front airbags are not intended
to deploy in collisions in which sufficient
protection can be provided by the pre-
tensioner seat belt.
o If you are considering modification of
your vehicle due to a disability, please
contact the Hyundai Customer Assis-
tance Center at 1-800-633-5151.o Never lean against the door or center
console – always sit in an upright posi-
tion.
o Do not allow an adult passenger to ride
in the front seat when the "Passenger
Airbag OFF" indicator is illuminated,
because the airbag will not deploy in the
event of a moderate or severe frontal
crash.
o Never place objects over or near any
airbag module (front or side impact
airbags), because these objects can
injure passengers in a crash.
o Never place covers, blankets or after-
market seat warmers on the passenger
seat as these may interfere with the
occupant classification system.
o Do not tamper or disconnect SRS wiring
or other components. Injuries could
result from inadvertent deployment or
failure of the airbag to deploy in a crash.
o If the SRS airbag warning light (see pg
1-52) remains illuminated while the ve-
hicle is being driven, have an autho-
rized Hyundai dealer inspect the airbag
system as soon as possible.
o Airbags can only be used once – have
an authorized Hyundai dealer replace
the airbag immediately after
deployment.
WARNING:

1FEATURES OF YOUR HYUNDAI38
!
WARNING:
o Move your seat as far back as
practical from the front airbags, while
still maintaining control of the vehicle.
You and your passengers should
never sit or lean unnecessarily close
to the airbags. Improperly positioned
drivers and passengers can be
severely injured by inflating airbags.
o No objects should be placed over or
near the airbag modules on the steer-
ing wheel, instrument panel, and the
front passenger's panel above the
glove box, because any such object
could cause harm if the vehicle is in a
crash severe enough to cause the
airbags to deploy.
o If the airbags deploy, they must be
replaced by an authorized Hyundai
dealer. Deployed airbags WILL NOT
inflate again and will provide no
protection in subsequent collisions.
o Do not tamper with or disconnect SRS
wiring or other components of the
SRS system. Doing so could result in
injury, due to accidental deployment
of the airbags or by rendering the SRS
inoperative.
!
WARNING:
o The SRS is designed to deploy the
front airbags only when an impact is
sufficiently severe and when the
impact angle is less than 30° from the
forward longitudinal axis of the
vehicle. The front airbags will not
deploy in side, rear or rollover im-
pacts. Additionally, the airbags will
only deploy once. Seat belts must be
worn at all times.
o Front airbags are not intended to de-
ploy in side-impact, rear-impact or
rollover crashes. In addition, front
airbags will not deploy in frontal
crashes below the deployment
threshold.
!
WARNING:
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint
system in the front passenger seat
position. A child restraint system
must never be placed in the front seat.
The infant or child could be severely
injured or killed by an airbag deploy-
ment in case of an accident.
o Children younger than 13 years must
always be properly restrained in the
rear seat. Never allow children to ride
in the front passenger seat. If a child
over 13 must be seated in the front
seat, he or she must be properly belted
and the seat should be moved as far
back as possible.
o For maximum safety protection in all
types of crashes, all occupants in-
cluding the driver should always wear
their seat belts whether or not an
airbag is also provided at their seating
position to minimize the risk of severe
injury or death in the event of a crash.
Do not sit or lean unnecessarily close
to the airbag while the vehicle is in
motion.

The SRSCM continually monitors all
elements while the ignition is "ON" to
determine if a frontal or near-frontal impact
is severe enough to require airbag
deployment or pre-tensioner seat belt
deployment.
The SRS airbag warning light on the in-
strument panel will illuminate for about 6
seconds after the ignition key is turned to
the "ON" position or after the engine is
started, after which the airbag warning
light should go out.
!
WARNING:
o Sitting improperly or out of position
can result in serious or fatal injury in
a crash. All occupants should sit
upright with the seat back in an upright
position, centered on the seat cushion
with their seat belt on, legs comfortably
extended and their feet on the floor
until the vehicle is parked and the
ignition key is removed.
o The SRS airbag system must deploy
very rapidly to provide protection in a
crash. If an occupant is out of position
because of not wearing a seat belt, the
airbag may forcefully contact the oc-
cupant causing serious or fatal
injuries.

Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
airbags. Further opening of the covers
then allows full inflation of the airbags.A fully inflated airbag, in combination with
a properly worn seat belt, slows the driver's
forward motion, reducing the risk of head
and chest injury.
After complete inflation, the airbag
immediately starts deflating, enabling the
driver to maintain forward visibility and the
ability to steer or operate other controls.
B240B03L
The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box.
When the SRSCM detects a sufficiently
severe impact to the front of the vehicle, it
will automatically deploy the front airbags.
CAUTION:
o Do not install or place any accesso-
ries (drink holder, cassette holder,
sticker, etc.) on the front passenger's
panel above the glove box in a vehicle
with a passenger's airbag. Such ob-
jects may become dangerous pro-
jectiles and cause injury if the
passenger's airbag inflates.
o When installing a container of liquid
air freshener inside the vehicle, do
not place it near the instrument cluster
nor on the instrument panel surface.
If there is any leakage from the air
freshener onto these areas
(instrument cluster, instrument panel
or air ventilator), it may damage these

!Always wash all exposed skin areas
thoroughly with lukewarm water and
a mild soap after an accident in which
the airbags were deployed.
o The SRS can function only when the
ignition key is in the "ON" position. If
the SRS airbag warning light does not
illuminate, or continuously remains
on after illuminating for about 6
seconds when the ignition key is
turned to the "ON" position, or after
the engine is started, comes on while
driving, the SRS is not working
properly. If this occurs, have your
vehicle immediately inspected by
your Hyundai dealer.
o Before you replace a fuse or discon-
nect a battery terminal, turn the igni-
tion key to the "LOCK" position and
remove the ignition key. Never remove
or replace the airbag related fuse(s)
when the ignition key is in the "ON"
position. Failure to heed this warning
will cause the SRS airbag warning
light to illuminate. parts. If the liquid from the air fresh-
ener does leak onto these areas, wash
them with water immediately.
WARNING:
o If an airbag deploys, there may be a
loud noise followed by a fine dust
released in the vehicle. These
conditions are normal and are not
hazardous - the airbags are packed in
this fine powder. The dust generated
during airbag deployment may cause
skin or eye irritation as well as
aggravate asthma for some persons.
WARNING:OCCUPANT CLASSIFICATION SYS-
TEM
Your vehicle is equipped with an occupant
classification system in the front
passenger's seat.
The occupant classification system is de-
signed to detect the presence of a prop-
erly-seated front passenger and deter-
mine if the passenger's front air bag should
be enabled (may inflate) or not. The driver's
front air bag is not affected or controlled by
the occupant classification system.

1FEATURES OF YOUR HYUNDAI42
B990A04NF-AATMain components of occupant clas-
sification systemo A detection device located within the
front passenger seat cushion.
o Electronic system to determine whether
passenger air bag systems (both front
and side) should be activated or deac-
tivated.
o A warning light located on the instru-
ment panel which illuminates the words
"PASSENGER AIR BAG OFF" indicat-
ing the front passenger air bag system
is deactivated.
o The instrument panel air bag warning
light is interconnected with the occu-
pant classification system.If the front passenger seat is occupied by
a person that the system determines to be
of adult size, and he/she sits properly (sit-
ting upright with the seatback in an upright
position, centered on the seat cushion with
their seat belt on, legs comfortably ex-
tended and their feet on the floor), the
"PASSENGER AIR BAG OFF" indicator
will be turned off and the front passenger's
air bag will be able to inflate, if necessary,
in frontal crashes.
You will find the "PASSENGER AIR BAG
OFF" indicator on the center facia panel.
This system detects the conditions 1~4 in
the following table and activates or
deactivates the front passenger air bag
based on these conditions.
ONF038024N
Always be sure that you and all vehicle
occupants are seated and restrained prop-
erly (sitting upright with the seat in an
upright position, centered on the seat cush-
ion, with the person’s legs comfortably
extended, feet on the floor, and wearing
the safety belt properly) for the most effec-
tive protection by the air bag and the safety
belt.
o The OCS (Occupant Classification Sys-
tem) may not function properly if the
passenger takes actions which can
defeat the detection system. These in-
clude:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center
console.
(3) Sitting towards the sides or the front
of the seat.
(4) Putting legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.
