Introduction
Petrol engine
Unlead
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 ethanol 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
drivability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the useof:
1. Ethanol containing more than 10%.
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 tothe catalytic converter and willdamage the engine control sys-
tem’s oxygen sensor and affectemission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consult
an authorised Hyundai dealer fordetails.)
CAUTION
Do not "top off" after the nozzle
automatically shuts off whenrefuelling.
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 containsmethanol. Discontinue use of any
ethanol product which impairs dri- vability.

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.
Do not attempt to service or repair the pre-tensioner seat belt
system in any manner.
(Continued)(Continued)
Improper handling of the pre-ten-sioner seat belt assemblies, and failure 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.
Always wear the seat belts when driving or riding in a motor vehi-
cle.
If the vehicle or pre-tensioner seat belt must be discarded, con-tact an authorised Hyundai deal-
er.CAUTION
Because the sensor that activates
the SRS air bag is connected withthe pre-tensioner seat belt, the SRS air bag warning light on the
instrument panel will illuminatefor approximately 6 seconds afterthe ignition key has been turned to the "ON" position, and then it
should turn off.
If the pre-tensioner seat belt is not working properly, this warninglight will illuminate even if there is
no malfunction of the SRS air bag.If the SRS air bag warning lightdoes not illuminate when the igni- tion key is turned to "ON", or if it
remains illuminated after illumi-nating for approximately 6 sec- onds, or if it illuminates while thevehicle is being driven, please
have an authorised Hyundai deal-er inspect the pre-tensioner seat belt or SRS air bag system assoon as possible.

SRS components and functions
The SRS consists of the following com- ponents:
1. Front Impact Sensors
2. SRS Air Bag Warning Light*
3. Passenger's Air bag Module*
4. Driver's Air Bag Module
5. SRS Control Module (SRSCM)
6. Side Impact Sensors*
7. Retractor Pre-tensioner Assemblies*
8. Side Air Bag Modules*
9. Curtain Air Bag Modules** If equippedThe SRSCM continually monitors all ele-
ments while the ignition switch is ON to
determine if a frontal or near-frontal
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.
The air bag modules are located both in
the centre of the steering wheel and in
the front passenger's panel above the
glove box. When the SRSCM detects a
sufficiently severe impact to the front of
the vehicle, it will automatically deploy
the front air bags.

Safety system of your vehicle
The side air bags are designed to deploy
only during certain side-impact collisions,
depending on the crash severity, angle,
speed and point of impact. The side air
bags are not designed to deploy in all
side impact situations.
Important safety notes on the sideairbag system
Following is a number of safety points
concerning this system which should
always be observed to ensure risk of
injury is reduced in an accident.
(Continued)
For best protection from the side air bag system and to avoid being
injured by the deploying side air
bag, both front seat occupantsshould sit in an upright position
with the seat belt properly fas-
tened. The driver's hands shouldbe placed on the steering wheelat the 9:00 and 3:00 positions.
The passenger's arms and handsshould be placed on their laps.
Do not use any accessory seat covers.
Use of seat covers could reduce or prevent the effectiveness ofthe system.
Do not install any accessories on the side or near the side 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 air
bag inflates.
(Continued)(Continued)
To prevent unexpected deploy-ment of the side air bag that may
result in personal injury, avoidimpact to the side impact sensor
when the ignition key is on.
WARNING
The side air bag is supplemental to the driver's and the passen-
ger's seat belt systems and is not
a substitute for them. Therefore
your seat belts must be worn at
all times while the vehicle is in
motion. The air bags deploy only
in certain side impact conditions
severe enough to cause signifi-
cant injury to the vehicle occu-pants.

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 bag
Front air bags are designed to inflate in a frontal collision depending on the intensi-
ty, speed or angles of impact of the front
collision - generally from an area a little
to the left to a little to the right of straightahead.
1JBA3513M
WARNING
Do not hit or allow any objects to impact the locations where air bag
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.

Side air bags (if equipped)
Side air bags (side 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 side
impact collision or rollover. 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
and/or curtain air bags) are designed to
inflate only in side impact collisions, but
they may inflate in other collisions if theside impact sensors detect a sufficientimpact.
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.

Safety system of your vehicle
Frontal air bags are not designed toinflate 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 or curtain air bags may
inflate depending on the intensity, vehi-cle speed and angles of impact. 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.
