NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Petrol engine
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. Do not use
methanol blended fuels.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.

•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.
WARNING
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.)

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
(4) Emergency Fastening Device
(EFD) (if equipped)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 to 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
illuminated or illuminates when
the vehicle is being driven, we rec-
ommend the pre-tensioner seat
belts and/or SRS air bags be
inspected by an authorised
HYUNDAI dealer as soon as possi-
ble.
Information
• Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal or side
collisions.
• The pre-tensioners will be activated
even if the seat belts are not worn at
the time of the collision.
• 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 condi-
tions and are not hazardous.
• Although it is non-toxic, the fine
dust may cause skin irritation and
should not be breathed for pro-
longed periods. Wash all exposed
skin areas thoroughly after an acci-
dent 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)/
Rollover sensor (8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Driver’s and front passenger’s
seat belt buckle sensors (if
equipped).
The SRSCM continually monitors
SRS components except for buckle
sensor whilst the ignition switch is in
the ON position to determine if a
crash impact is severe enough to
require air bag deployment or pre-
tensioner seat belt deployment.
OTL035079L/H
Do not place any objects over
the air bag. Also, do not attach
any objects around the area
the air bag inflates such as
the door, side door glass,
front and rear pillar, roof side
rail.
Do not hang hard or breakable
objects on the clothes hanger.
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 turned 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.
There is no single speed at which
the air bags will inflate. Generally,
air bags are designed to inflate
based upon the severity of a colli-
sion and its direction. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/inflation signal. 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.
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.

Why didn’t my air bag go off in
a collision?
There are certain types of accidents
in which the air bag would not be
expected to provide additional pro-
tection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehi-
cle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should
have inflated.
Air bag collision sensors
(if equipped)
To reduce the risk of an air bag
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.
WARNING
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, speed or angles of
impact of the front collision.
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, speed or
angles 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.

Safety system of your vehicle
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 deceleration
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.
Information
Vehicles equipped with rollover sensor
The side and curtain air bags may
inflate in a rollover situation, when it
is detected by the rollover sensor.
