FUEL REQUIREMENTS
Petrol engine
Unleaded
Your new vehicle is designed to use only
unleaded fuel having an Octane Rating
of RON (Research Octane Number) 91 /
AKI (Anti-Knock Index) 87 or higher. (Do
not use methanol blended fuels)
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The use
of leaded fuel is detrimental 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 specified (We recommend
that you consult an authorized
HYUNDAI dealer for details.)
WARNING
• Do not “top off” after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster 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 illuminate 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 recommend the pre-
tensioner seat belts and/or SRS control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
i Information
• Both the driver’s and front passenger’s
pre-tensioner seat belts may be
activated in certain frontal or side
collisions.
• 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 inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.
Additional seat belt safety
precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat
belt. Pregnant women should always
wear a lap-shoulder seat belt. Place the
shoulder belt across your chest, routed
between your breasts and away from
your neck. Place the lap belt below your
belly so that it fits SNUGLY across your
hips and pelvic bone, under the rounded
part of the belly.
WARNING
To reduce the risk of serious injury or
death to an unborn child during an
accident, pregnant women should
NEVER place the lap portion of the
seat belt above or over the area of the
abdomen where the unborn child is
located.
Seat belt use and children
Infant and small children
Most countries have Child Restraint
System laws which require children
to travel in approved Child Restraint
System devices, including booster seats.
The age at which seat belts can be
used instead of Child Restraint System
differs among countries, so you should
be aware of the specific requirements
in your country, and where you are
travelling. Infant and Child Restraint
System must be properly placed and
installed in a rear seat. For more details
refer to the “Child Restraint Systems”in
this chapter.

Safety system
WARNING
• Even in vehicles with air bags, you
and your passengers must always
wear the safety belts provided
in order to minimize the risk and
severity of injury in the event of a
collision or rollover.
• SRS and pretensioners contain
explosive chemicals.
If scraping a vehicle without
removing SRS and pretensioners
from a vehicle, it may cause fire.
Before scraping a vehicle, we
recommend that you contact an
authorized Hyundai dealer.
• Keep the SRS parts and wirings away
from water or any liquid. If the SRS
components are inoperative due to
exposure to water or liquids, it may
cause fire or severe injury.
How does the air bag system
operate
• Air bags are activated (able to inflate
if necessary) only when the ignition
switch is placed to the ON or START
position.
• Air bags inflate instantly in the event
of serious frontal or side collision in
order 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
collision and its direction. These two
factors determine whether the sensors
produce an electronic deployment/
inflation signal.
• Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles or
objects which your vehicle hits in the
collision. The determining, factors are
not limited to those mentioned above.
• The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to see
the air bags inflate during an accident.
It is much more likely that you
will simply see the deflated air
bags hanging out of their storage
compartments after the collision.

SRS components and functions
OBI3030006OBI3030006
The SRS consists of the following
components:
(1) Driver’s front air bag module
(2) Passenger’s front air bag module
(3) Pre-tensioner seatbelt system*
(4) Air bag warning light
(5) SRS control module (SRSCM)
(6) Front impact Sensor
(7) Side air bag modules*
(8) Curtain air bag modules *
(9) Side impact sensors *
* : if equippedThe SRSCM continuously monitors all
SRS components while the ignition
switch is ON to determine if a crash
impact is severe enough to require air
bag deployment or pre-tensioner seat
belt deployment.
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. WARNING
If any of the following conditions
occurs, this indicates a malfunction
of the SRS. We recommend that the
system be inspected by an authorized
HYUNDAI dealer.
• The light does not turn on briefly
when you turn the ignition ON.
• The light stays on after illuminating
for approximately 6 seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the ignition
switch is in ON position.

Safety system
• Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.
• Do not place any objects between the
door and the seat. They may become
dangerous projectiles if the side air
bag inflates.
• Do not put any objects between the
side air bag label and seat cushion. It
could cause harm if the vehicle is in a
crash severe enough to cause the air
bags to deploy.
• To prevent unexpected deployment
of the side air bag that may result in
personal injury, avoid impact to the
side impact sensor when the ignition
switch is on.
• If the seat or seat cover is damaged,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.
• Inform the dealer that your vehicle is
equipped with side air bags.Curtain air bag (if equipped)
OQXI039024OQXI039024
OQXI039025OQXI039025
The actual air bags in the vehicle may differ
from the illustration.
Curtain air bags are located along both
sides of the roof rails above the front
and rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash
severity, angle, speed and impact. The
curtain air bags are not designed to
deploy in all side impact situations,
collisions from the front or rear of the
vehicle or in most rollover situations.

WARNING
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
This may cause unexpected air bag
deployment, which could result in
serious personal injury or death.
• If the installation location or angle
of the sensors is altered in any way,
the air bags may deploy when they
should not or they may not deploy
when they should, causing severe
injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. We recommend that the
system be serviced by an authorized
HYUNDAI dealer.
• Problems may arise if the sensor
installation angles are changed
due to the deformation of the front
bumper and body. We recommend
that the system be serviced by an
authorized HYUNDAI dealer.
• Your vehicle has been designed to
absorb impact and deploy the air
bag(s) in certain collisions. Installing
aftermarket bumper guards or
replacing a bumper with non-
genuine parts may adversely affect
your vehicles collision and air bag
deployment performance.
Air bag inflation conditions
OBC3030027OBC3030027
Front air bags
Front air bags are designed to inflate in
certain frontal collision depending on
the crash severity, speed or angles of
impact of the front collision.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads
or sidewalks, air bags may deploy.
Drive carefully on unimproved roads
or on surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.
