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
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.)
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 acci-dent.
CAUTION
Never use ethanol which contains
methanol. Discontinue use of anyethanol 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
Pre-tensioners are designed to operate only one time. After acti-
vation, 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.
The pre-tensioner seat belt assembly mechanisms become
hot during activation. Do not
touch the pre-tensioner seat belt
assemblies for several minutes
after they have been activated.
Do not attempt to inspect or replace the pre-tensioner seat
belts yourself. This must be done
by an authorised HYUNDAI dealer.
Do not strike the pre-tensioner seat belt assemblies.
Improper handling of the pre-ten- sioner seat belt assemblies, andfailure to heed the warnings not
to strike, modify, inspect, replace,
service or repair the pre-tension-
er seat belt assemblies may lead
to improper operation or inadver-
tent activation and serious injury.
(Continued)CAUTION
If the pre-tensioner seat belt is notworking properly, this warning light
will illuminate even if there is nomalfunction 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 isbeing driven, please have an autho-rised HYUNDAI dealer inspect thepre-tensioner seat belt or 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 serious frontal or side collision in order
to help protect the occupants from seri-
ous 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 bag
inflation is a consequence of extreme-
ly short time in which a collision occursand the need to get 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 colli-
sion 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 possible
(at least 250 mm (10 inches)
away). The front passenger should
always move their seat as far
back as possible and sit back intheir seat.
Air bag inflates instantly in an event of a collision, passengers
may be injured by the air bag
expansion force if they are not in
a proper position.
Air bag inflation may cause injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

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 impact 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 The SRSCM continuously monitors all SRS components whilst 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. Have an authorised
HYUNDAI dealer inspect the air bag
system as soon as possible.
The light does not turn on briefly when you turn the ignition ON.
The light stays on after illuminat- ing 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.

Curtain air bag (if equipped)
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 andthe rear outboard seat occupants in cer-
tain side impact collisions.
(Continued)
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 seat or seat cover is damaged, have the vehicle checked and
repaired by an authorised
HYUNDAI dealer. Inform the deal-
er that your vehicle is equipped
with side impact air bags.WARNING
The side impact air bag is sup- plemental to the driver's and the
passenger's seat belt systems
and is not a substitute for them.
Therefore your seat belts must be
worn at all times whilst the vehi-
cle 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 seat occupants shouldsit in an upright position with the
seat belt properly fastened. Thedriver's hands should be placedon the steering wheel at the 9:00
and 3:00 positions. The passen-
ger's arms and hands should beplaced on their laps.
Do not use any accessory seat covers.
Use of seat covers could reduce or prevent the effectiveness ofthe system.

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.
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.
(Continued)(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B pillar
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 aftermarket bumper
guards or replacing a bumper
with non-genuine parts may
adversely affect your vehicles
collision and air bag deployment
performance.

Safety features of your vehicle
Side air bags
Side air bags (side impact and/or curtain air bags) are designed to inflate when an
impact is detected by side collision sen-sors depending 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 air bags (side
impact and/or curtain air bags) aredesigned to inflate only in side impact
collisions, but they may inflate in othercollisions if the side impact sensorsdetect a sufficient impact.
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 sur-
faces 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.

Frontal air bags are not designed to
inflate in rear collisions, because occu-
pants are moved backward by the
force of the impact. In this case, inflat-
ed air bags would not be able to pro-
vide any additional benefit. Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, frontal air bag
deployment would not provide addi-tional occupant protection.
However, side impact or curtain air
bags may inflate depending on the
intensity, vehicle speed and angles ofimpact. In a slant or 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 bene-
fit, and thus the sensors may not
deploy any air bags.

Safety features of your vehicle
Just before impact, drivers often brakeheavily. 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 signifi-
cantly reduced by such “under-ride”
collisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, side and/or curtain air bags may inflate when the vehicle is rolled
over by a side impact collision, if the
vehicle is equipped with side impact air
bags and curtain air bags. Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehicle
structure.
