Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Petrol engine
Unleaded
Yo u r n e w v e h i c l e i s d e s i g n e d t o u s e
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. Do not use
methanol blended fuels.
Yo u r n e w v e h i c l e i s d e s i g n e d t o
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WA R N I N G
NEVER USE LEADED FUEL.
The use of leaded fuel is detri-
mental to the catalytic converter
and will damage the engine
control system’s oxygen sensor
and affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been spec-
ified. We recommend that you
consult an authorised HYUNDAI
dealer for details.
CAUTION
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
(1) SRS air bag warning light
(2) Retractor pre-tensioner
(3) SRS control module
The sensor that activates the SRS
air bag is connected with the
pre–tensioner seat belts. The SRS
air bag warning light on the instru-
ment panel will illuminate for
approximately 6 seconds after the
ignition switch is placed in the ON
position, and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate even if the SRS air bag is
not malfunctioning. If the warning
light does not illuminate, stays illu-
minated or illuminates when the
vehicle is being driven, we recom-
mend the pre-tensioner seat belts
and/or SRS air bags be inspected
by an authorised HYUNDAI dealer
as soon as possible.
•Both the driver's and front pas-
senger's pre-tensioner seat
belts may be activated in certain
frontal or side collisions.
•The pre-tensioners will be acti-
vated even if the seat belts are
not worn at the time of the colli-
sion.
•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
compartment. These are normal
operating conditions and are not
hazardous.
•Although it is non-toxic,the fine
dust may cause skin irritation
and should not be breathed for
prolonged periods. Wash all
exposed skin areas thoroughly
after an accident in which the
pre-tensioner seat belts were
activated.

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)
(8) Front impact sensors
(9) Side impact sensors
(10) Side Pressure sensors
The SRSCM continually monitors
SRS components whilst the ignition
switch is in the ON position to deter-
mine if a crash impact is severe
enough to require air bag deploy-
ment or pre-tensioner seat belt
deployment.
To r e d u c e t h e r i s k o f s e r i o u s
injury or death from an inflating
curtain air bag, take the follow-
ing precautions:
•All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly.
•Properly secure child restraints
as far away from the door as
possible.
•Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
•Do not open or repair the side
curtain air bags.

SRS warning light
The SRS air bag warning light on the
instrument panel will illuminate for
about 6 seconds after the ignition
switch is tur ned to the ON position,
after which the air bag warning light
should go out.
During a frontal collision, sensors will
detect the vehicle’s deceleration. If
the rate of deceleration is high
enough, the control unit will inflate
the front air bags, at the time and
with the force needed.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact.
•Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON posi-
tion.
•Air bags inflate in the event of cer-
tain frontal or side collisions to help
protect the occupants from serious
physical injury.
•Generally, air bags are designed to
inflate based upon the severity of a
collision it’s direction etc. These
two factors determine whether the
sensors produce an electronic
deployment/inflation signal.
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:
•The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
•The light stays on after illumi-
nating for approximately six
seconds.
•The light comes on whilst the
vehicle is in motion.
•The light blinks when the
engine is running.
We recommend that an autho-
rised HYUNDAI dealer inspect
the SRS as soon as possible if
any of these conditions occur.

Why didn't my air bag go off in
a collision?
Air bags are not designed to inflate in
ever y collision.
There are certain types of accidents
in which the air bag would not be
expected to provide additional protec-
tion. These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehicle
indicates a collision energy absorp-
tion, and is not an indicator of whether
or not an air bag should have inflated.
Air bag collision sensors
(if equipped)
To r e d u c e t h e r i s k o f a n a i r b a g
deploying unexpectedly and
causing serious injury or death:
•Do not hit or allow any objects
to impact the locations where
air bags or sensors are
installed.
•Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
•Do not install bumper guards
or replace the bumper with a
non-genuine part. This may
adversely affect the collision
and air bag deployment per-
formance.

(Continued)
•Place the ignition switch to
the LOCK/OFF or ACC posi-
tion, when the vehicle is being
towed to prevent inadvertent
air bag deployment.
•We recommend that all air bag
repairs are conducted by an
authorised HYUNDAI dealer.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the severity of impact of the front col-
lision.
.
Side and curtain air bags
Side and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the severity of impact
resulting from a side impact collision.
Although the driver’s and front pas-
senger’s air bags are designed to
inflate only in frontal collisions, they
also may inflate in other types of col-
lisions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed to
inflate only in side impact collisions,
but they may inflate in other colli-
sions if the side impact sensors
detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.

In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.
Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to “ride” under a vehicle
with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because decel-
eration forces that are detected by
sensors may be significantly reduced
by such “underride” collisions.
Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
