FEATURES OF YOUR HYUNDAI 1- 27
NOTE:o Both the driver's and front passenger's
pre-tensioner seat belts will be activated
in certain frontal collisions. The pre-
tensioner seat belts can be activated
alone or, where the frontal collision is
severe enough, together with the
airbags.
o When the pre-tensioner seat belts are
activated, a loud noise may be heard and
fine dust, which may appear to be smoke,
may be visible in the passenger com-
partment. 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 periods. Wash
your hands and face thoroughly after an
accident in which the pre-tensioner seat
belts were activated.
CAUTION:o Because the sensor that activates the
SRS airbag is connected with pre-
tensioner seat belt, the SRS airbag warn-
ing light on the instrument panel will
blink 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 work-
ing properly, this warning light will illu-
minate even if there is no malfunction of
SRS airbag system. If the SRS airbag
warning light does not illuminate when
the ignition key is turned to "ON" or if it
remains illuminated after blinking for
approximately 6 seconds, or if it illumi-
nates while the vehicle is being driven,
please have an authorized Hyundai dealer
inspect the pre-tensioner seat belt or
SRS airbag system as soon as possible.

WARNING:o Pre-tensioners are designed to operate
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 assembly
mechanisms become hot during activa-
tion. 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 yourself. This
must be done by an authorized 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, in-
spect, replace, service or repair the pre-
tensioner seat belt assemblies may lead
to improper operation or inadvertent
activation and serious injury.
o Always wear the seat belts when driving
or riding in a motor vehicle.

B240A03Y-AATSUPPLEMENTAL RESTRAINT
(AIRBAG) SYSTEM (SRS)NOTE:Be sure to read information about the SRS
on the labels provided on the backside of
the sun visor and in the glove box.
o Front airbags are not intended to deploy
in side-impact, rear-impact or rollover
crashes. In addition, airbags will not
deploy in frontal crashes below the de-
ployment threshold speed.
o The driver should sit back as far as
possible while still maintaining control
of the vehicle. If you are sitting too close
to the airbag, it can cause death or seri-
ous injury when it inflates.
o No objects should be placed over or near
the airbag modules on the steering 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 re-
placed by an authorized Hyundai dealer. Your Hyundai is equipped with a Supplemental
Restraint (Airbag) System. 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 the
front passenger with additional protection when
used together with the seat belt, in case of a
frontal impact.
WARNING:o As its name implies, the SRS is designed
to work with, and be supplemental to,
the driver’s and the passenger’s three
point seat belt systems and is not a
substitute for them. Therefore your seat
belts must be worn at all times while the
vehicle is in motion. In addition, the
airbags deploy only in certain frontal
impact conditions severe enough to likely
cause significant injury to the vehicle
occupants.
o The SRS is designed to deploy the
airbags only when an impact is suffi-
ciently severe and when the impact angle
is less than 30° from the forward longi-
tudinal axis of the vehicle. Additionally,
the airbags will only deploy once. Thus,
seat belts must be worn at all times.
o Front airbags are not intended deploy in
light collisions in which protection can
be provided by the seat belt.

!
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 considerable im-
pact to the front of the vehicle, it will automatically
deploy the airbags.
Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure 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 or the
passenger's forward motion, thus reducing the
risk of head or chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.
CAUTION:When installing the container of liquid air
freshener inside a vehicle, do not place it
near the instrument cluster nor on the in-
strument panel pad surface. If there is any
leakage from the air freshener onto these
areas (Instrument cluster, instrument panel
pad or air ventilator), it may damage these
parts. If the liquid from the air freshener
does leak onto these areas, wash them with
water immediately.
WARNING:o When the SRS is activated, there may be
a loud noise and fine dust will be re-
leased throughout the vehicle. These
conditions are normal and are not haz-
ardous. However, the fine dust gener-
ated during airbag deployment may
cause skin irritation. Be sure to wash
your hands and face thoroughly with
lukewarm water and a mild soap after an
accident in which the airbags were de-
ployed.
o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS SRI does not come on, or continu-
ously remains on, after flashing for about
6 seconds when the ignition key is
turned to the "ON" position, or after the
engine is started, or comes on while
driving, the SRS is not working properly.
If this occurs, have your vehicle immedi-
ately inspected by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position or remove the
ignition key. Never remove or replace the
air bag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS SRI
to illuminate.

tem, temporarily set the air intake control at
the position. Be sure to return the control
to the position when the irritation has
passed to keep fresh air in the vehicle. This
will help keep the driver alert and comfort-
able.
o Air for the heating/cooling system is drawn
in through the grilles just ahead of the wind-
shield. Care should be taken that these are
not blocked by leaves, snow, ice or other
obstructions.
