Introduction
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.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimise exhaust emis-
sions and spark plug fouling.
Petrol containing alcohol andmethanol
Ethanol [E-10], a mixture of petrol and
ethanol (also known as grain alcohol),and petrol or ethanol containing
methanol (also known as wood alcohol)
are being marketed along with or insteadof leaded or unleaded petrol. Do not use petrol containing more than 10% ethanol, and do not use petrol or
ethanol containing any methanol. Either
of these fuels may cause drivability prob-lems and damage to the fuel system.
Discontinue using ethanol of any kind if
driveability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the useof:
1. Petrol containing more than 10% ethanol.
2. Petrol or ethanol containing methanol.
3. Leaded fuel or leaded ethanol.
FUEL REQUIREMENTS
WARNING
• Do not "top off" after the nozzle automatically shuts off when refuelling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and willdamage the engine control sys-tem’s oxygen sensor and affect emission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consultan authorised HYUNDAI dealer for
details.)
CAUTION
Never use ethanol which containsmethanol. Discontinue use of any ethanol product which impairs dri-
veability.

✽✽NOTICE
 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 oper-
ating conditions and are not haz-
ardous.
 Although it is harmless, the fine dust may cause skin irritation and should
not be breathed for prolonged peri-
ods. Wash all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were activat-
ed.
 Because the sensor that activates the SRS air bag is connected with the pre-
tensioner seat belt, the SRS air bag
warning light on the instrument
panel will illuminate for approximate-
ly 6 seconds after the ignition switch
has been turned to the ON position,
and then it should turn off.WARNING
To obtain maximum benefit from a pre-tensioner seat belt:
1. The seat belt must be worn cor- rectly and adjusted to the proper
position. Please read and follow
all of the important information
and precautions about your vehi-
cle’s occupant safety features –
including seat belts and air bags
– that are provided in this manu-al.
2. Be sure you and your passen- gers always wear seat belts prop-
erly.CAUTION
If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no malfunction of the SRS air bag. Ifthe SRS air bag warning light does not illuminate when the ignition
switch is turned to ON, or if itremains illuminated after illuminat- ing for approximately 6 seconds, or
if it illuminates whilst the vehicle is being driven, have an authorisedHYUNDAI dealer inspect the pre-tensioner seat belt and SRS air bag
system as soon as possible.

How does the air bag system operate
Air bags are activated (able to inflate ifnecessary) only when the ignition
switch is turned to the ON or STARTposition.
Air bags inflate instantly in the event of a serious frontal or side collision (if
equipped with side air bag or curtainair bag) 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 col-
lision and its direction. These two fac-
tors determine whether the sensors
produce an electronic deployment/inflation signal.
Air bag deployment depends on a number of factors including vehiclespeed, angles of impact and the densi-
ty 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 sim-ply see the deflated air bags hanging
out of their storage compartments afterthe collision.
In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air baginflation is a consequence of the
extremely short time in which a collisionoccurs and the need to inflate the air
bag between the occupant and the
vehicle structures before the occupant
impacts those structures. This speed of
inflation reduces the risk of serious or
life-threatening injuries in a severe col-
lision and is thus a necessary part of airbag design.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bonesbecause the inflation speed also caus-
es the air bags to expand with a great
deal of force.
There are even circumstances under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close tothe steering wheel.
WARNING
To avoid severe personal injury or death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 250 mm (10 inches)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
Air bags inflate instantly in the event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
proper position.
Air bag inflation may cause injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

Air bag warning light
The purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the warning light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
The light does not turn on briefly whenyou turn the ignition ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on whilst the vehicle is in motion.
The light blinks when the ignition switch is in ON position. SRS components and functions
The SRS consists of the following com- ponents:
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 assemblies*
6. Air bag warning light
7. SRS control module (SRSCM)
8. Front impact sensors
9. Side impact sensors*
*: if equipped
(Continued)
When children are seated in the
rear outboard seats of vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,
and securely lock the childrestraint system in position.
Inflation of side and/or curtain air
bags could cause serious injury
or death to an infant or child.

Safety features of your vehicle
The side impact air bags are designed to
deploy only during certain side-impact
collisions, depending on the crash sever-
ity, angle, speed and point of impact. Theside impact air bags are not designed to
deploy in all side impact situations.
WARNING
Do not allow the 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 passengers when they areseated on seats equipped with side
and/or curtain air bags.
WARNING
The side impact air bag is sup- plemental to the seat belt sys-
tems and is not a substitute for
them. Therefore your seat belts
must be worn at all times whilst
the vehicle is in motion. The air
bags deploy only in certain side
impact conditions severe enough
to cause significant injury to the
vehicle occupants.
For best protection from the side impact air bag system and to
avoid being injured by the
deploying side impact air bag,
both front and all rear (ifequipped) seat occupants shouldsit in an upright position with the
seat belt properly fastened. Thedriver's hands should be placedon the steering wheel at the 9 and
3 o’clock positions. The passen-
gers’ arms and hands should beplaced on their laps.
Do not use any accessory seat covers.
(Continued)(Continued)
Use of seat covers could reduceor prevent the effectiveness of the system.
Do not install any accessories on the side or near the side impact
air bag.
Do not place any objects over the air bag or between the air bag
and yourself.
Do not place any objects (an umbrella, bag, etc.) between the
front door and the front seat.
Such objects may become dan-
gerous projectiles and cause
injury if the supplemental side
impact air bag inflates.
To prevent unexpected deploy- ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switchis on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorised
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags.

Why didn’t my air bag go off in a collision? (Inflation and non-infla-
tion conditions of the air bag)
There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate in a frontal collision depending on the intensi-
ty, speed or angles of impact of the frontcollision.
(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B and C pil-
lars where side collision sensors
are installed. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.
Your vehicle has been designed to absorb impact and deploy the
air bag(s) in certain collisions.
Installing bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicle’s collision and air
bag deployment performance.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 injuryor 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. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.

Side impact and curtain air bags
(if equipped)
Side impact and curtain air bags are designed to inflate when an impact is
detected by side collision sensorsdepending on the strength, speed orangles of impact resulting from a sideimpact collision. Although the front air bags (driver’s and
front passenger’s air bags) are designed
to inflate only in frontal collisions, they
also may inflate in other types of colli-sions if the front impact sensors detect a
sufficient impact. Side impact and curtainair bags are designed to inflate only in
side impact collisions, but they mayinflate in other collisions if the sideimpact sensors detect a sufficientimpact.
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.
Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts
in such collisions.
