WARNING:
o Pre-tensioners are designed to op-
erate only one time. After activation,
pre-tensioner seat belts must be
replaced. All seat belts, of any type,
should always be replaced after they
have been worn during a collision.
o The pre-tensioner seat belt assem-
bly mechanisms become hot during
activation. Do not touch the pre-
tensioner seat belt assemblies for
several minutes after they have been
activated.o Do not attempt to inspect or replace
the pre-tensioner seat belts your-
self. This must be done by an autho-
rized Hyundai dealer.
o Do not strike the pre-tensioner seat
belt assemblies.
o Do not attempt to service or repair
the pre-tensioner seat belt system in
any manner.
o Improper handling of the pre-
tensioner seat belt assemblies, and
failure to heed the warnings to not
strike, modify, inspect, replace, ser-
vice or repair the pre-tensioner seat
belt assemblies may lead to improp-
er operation or inadvertent activa-
tion and serious injury.
o Always wear the seat belts when
driving or riding in a motor vehicle.
o If the vehicle or pre-tensioner seat
belt must be discarded, contact an
authorized HYUNDAI dealer.
WARNING:
CAUTION:
o The sensor that activates the SRS
airbag is connected with the pre-
tensioner seat belt. The SRS airbag
warning light on the instrument
panel will illuminate for approximately
6 seconds after the ignition key has
been turned to the "ON" position,
and then it should turn off.
o If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no mal-
function of the SRS airbag.
!
o When the pre-tensioner seat belts
are activated, a loud noise may be
heard and fine dust, which may ap-
pear to be smoke, may be visible in
the passenger compartment. These
are normal operating conditions and
are not hazardous.
o Although it is harmless, the fine dust
may cause skin irritation and should
not be breathed for prolonged peri-
ods. Wash your hands and face thor-
oughly after an accident in which the
pre-tensioner seat belts were acti-
vated.If the SRS airbag warning light does
not illuminate when the ignition key
is turned to the "ON" position, re-
mains 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 pos-
sible.

The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt system alone in
case of a frontal impact of sufficient sever-
ity. The SRS uses sensors to gather infor-
mation 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 (If Installed), 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 con-
trol 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 within two lev-
els. 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.
Additionally, your Hyundai 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
passenger's seat and will turn off the front
passenger's airbag under certain condi-
tions. For more detail, see "Occupant Clas-
sification System" later in this section.
B240A03NF-AATDriver's and Passenger's Front
AirbagYour Hyundai is equipped with an ad-
vanced Supplemental Restraint (Airbag)
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.Driver's Front Airbag

WARNING:
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
warning light is connected with the seat
track position sensor and the occupant
classification system. If the SRS airbag
warning light does not illuminate when
the ignition key is turned to the "ON"
position, remains illuminated after ap-
proximately 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.

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 provided.
o Do not place any objects underneath
the front seats as they could dam-
age the seat track position sensor or
interfere with the occupant classifi-
cation system.
o Do not place any objects that may
cause magnetic fields near the front
seat. These may cause a malfunc-
tion of the seat track position sen-
sor.
NOTE:o Be sure to read information about
the SRS on the labels provided on
the topside of the sun visor.
o Advanced airbags are combined with
pre-tensioner seat belts to help pro-
vide 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 Cus-
tomer Assistance Center at 1-800-

When an adult is seated in the front
passenger seat, if the “PASSENGER AIR
BAG OFF” indicator is on, turn the ignition
switch to the LOCK position and ask the
passenger to sit properly (sitting 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). Restart the
engine and have the person remain in
that position for about 30 seconds. This
will allow the system to detect the person
and to enable the passenger air bag.
If the "PASSENGER AIR BAG OFF" indi-
cator is still on, ask the passenger to
move to the rear seat.
!
WARNING:
Do not allow an adult passenger to ride
in the front seat when the “PASSENGER
AIR BAG OFF” indicator is illuminated
because the air bag will not deploy in the
event of a crash. If the "PASSENGER
AIR BAG OFF" indicator remains illumi-
nated after the adult passenger reposi-
tions themselves properly and the car is
restarted, it is recommended that pas-
senger move to the rear seat because
the passenger's front air bag will not
deploy.
Front seat passengers must stay prop-
erly seated to avoid serious injury from
a deploying air bag.
NOTE:The "PASSENGER AIR BAG OFF" indi-
cator illuminates for about 4 seconds
after the ignition switch is turned to the
ON position or after the engine is started.
If the front passenger seat is occupied,
the occupant classification sensor will
then classify the front passenger after
several more seconds.
Proper position
!
WARNING:
Do not put a heavy load or an active
electronic device (ex. laptop computer,
navigation etc..) in the front passenger
seatback pocket or on the front passen-
ger seat. Do not hang onto the front
passenger seat. Do not hang any items
such as seatback table on the front pas-
senger seatback. Do not place feet on
the front passenger seatback. Do not
place any items under the front passen-
ger seat. Any of these could interfere
with proper sensor operation.

WARNING:
o The side impact airbag is supple-
mental to the driver's and the
passenger's seat belt systems and
is not a substitute for them. There-
fore your seat belts must be worn at
all times while the vehicle is in mo-
tion. The airbags deploy only in cer-
tain side impact conditions severe
enough to cause significant injury to
the vehicle occupants.
o For best protection from the side
impact airbag system and to avoid
being injured by the deploying side
impact airbag, both front seat occu-
pants should sit in an upright posi-
tion with the seat belt properly fas-
tened. The driver's hands should be
placed on the steering wheel at the
9:00 and 3:00 positions. The
passenger's arms and hands should
be placed on their laps.
o Do not use any accessory seat cov-
ers.
Use of seat covers could reduce or
prevent the effectiveness of the sys-
tem.

Important Safety Notes on the Side
Impact Airbag SystemFollowing are a number of safety points
concerning this system which should al-
ways be observed to ensure risk of injury
is reduced in an accident.
!
o Do not install any accessories on the
side or near the side impact airbag.
o Do not place any objects over the
airbag or between the airbag and
yourself.
o Do not place any objects (an um-
brella, bag, etc.) between the front
door and the front seat. Such objects
may become dangerous projectiles
and cause injury if the supplemental
side impact airbag inflates.
o To prevent unexpected deployment
of the side impact airbag that may
result in personal injury, avoid im-
pact to the side impact sensor when
the ignition key is on.

!
CAUTION:
In winter or cold weather, the low
tire pressure telltale may be illumi-
nated if the tire pressure was ad-
justed to the recommended tire in-
flation pressure in warm weather. It
does not mean your TPMS is mal-
functioning because the decreased
temperature leads to a proportional
lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a
cold area to a warm area, or the
outside temperature is greatly
higher or lower, you should check
the tire inflation pressure and ad-
just the tires to the recommended
tire inflation pressure.
WARNING:
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheat
and fail.
TPMS (Tire Pressure Moni-
toring System) Malfunction
Indicator
The TPMS malfunction indicator comes
on and stays on when there is a
problem with the Tire Pressure Moni-
toring System. If the system is able to
correctly detect an under-inflation warn-
ing at the same time as system failure
then it will illuminate both the TPMS
malfunction and the low tire pressure
telltale e.g. if Front Left sensor fails,
the TPMS malfunction indicator turns
on, but if Front Right, Rear Left, or
Rear Right tire is under-inflated, the
low tire pressure telltale may turn on at
!
the same time as the TPMS malfunc-
tion indicator. Have the system
checked by an authorized Hyundai
dealer as soon as possible to deter-
mine the cause of the problem.
NOTE:
o The TPMS malfunction indicator
may be illuminated if the vehicle is
moving around electric power sup-
ply cables or radio transmitters
such as police stations, govern-
ment and public offices, broad-
casting stations, military installa-
tions, airports, or transmitting tow-
ers, etc. which can interfere with
normal operation of the Tire Pres-
sure Monitoring System (TPMS).
o The TPMS malfunction indicator
may be illuminated if snow chains
are used or some separate elec-
tronic devices such as notebook
computer, mobile charger, remote
starter or navigation etc., are used
in the vehicle. This can interfere
with normal operation of the Tire
Pressure Monitoring System
(TPMS).

38WHAT TO DO IN AN EMERGENCYo If there is a failed tire sensor, it is
possible for the TPMS to tempo-
rarily learn a replacement sensor
if closely driven to another ve-
hicle that is also equipped with
TPMS. In rare cases, this may
temporarily delay the TPMS mal-
function indicator from turning
on.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale will turn on. Have the
flat tire repaired by an authorized
Hyundai dealer as soon as possible or
replace the flat tire with the temporary
spare tire.
NOTE:
NEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have
to replace the tire pressure sensor.Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have your
tires serviced by an authorized Hyundai
dealer as soon as possible.
After you replace the low pressure tire
with the spare tire, the TPMS malfunc-
tion indicator or the Low Tire Pressure
telltale may illuminate after restarting
and about 20 minutes of continuous
driving.
Once the low pressure tire is re-in-
flated to the recommended pressure
and installed on the vehicle, the TPMS
malfunction indicator and the low tire
pressure telltale will be extinguished.
If the low pressure and TPMS mal-
function indicators are not extinguished
after about 20 minutes of continuous
driving, please visit an authorized
Hyundai dealer.
You may not be able to identify a low
tire by simply looking at it. Always use
a good quality tire pressure gauge to
measure the tire's inflation pressure.Please note that a tire that is hot (from
being driven) will have a higher pres-
sure measurement than a tire that is
cold (from sitting stationary for at least
3 hours and driven less than 1 mile
during that 3 hour period). Allow the
tire to cool before measuring the infla-
tion pressure.
Always be sure the tire is cold before
inflating to the recommended pres-
sure.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile in that 3 hour period.
