Introduction
Petrol engine
Unleaded
For the optimal vehicle performance,
we recommend you to use unleaded
petrol which has an EN 228 and has
an octane rating of RON (Research
Octane Number) 95 / AKI (Anti
Knock Index) 91 or higher.(Do not
use methanol blended fuels.)
You may use unleaded petrol with an
octane rating of RON 91-94 / AKI 87-
90 but it may result in slight perform-
ance reduction of the vehicle.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and
ethanol (also known as grain alco-
hol), and petrol or gasohol containing
methanol (also known as wood alco-
hol) are being marketed along with or
instead of leaded or unleaded petrol.
Do not use gasohol containing more
than 10% ethanol, and do not use
petrol or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasohol containing more than
10% ethanol.
2. Petrol or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
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 speci-
fied (We recommend that you
consult a HYUNDAI authorised
repairer for details.)
WARNING
• 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.

Safety features of your vehicle
Pre-tensioner seat belt
(if equipped)
Your vehicle is equipped with driver's
and front passenger's pre-tensioner
seat belts (retractor pretensioner and
EFD (Emergency Fastening Device)).
The pre-tensioner seat belts can be
activated, where the frontal collision
is severe enough, together with the
air bags.
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal
collisions, the pre-tensioner will acti-
vate and pull the seat belt into tighter
contact against the occupant's body.(1) Retractor Pretensioner
The purpose of the retractor pre-
tensioner is to make sure that the
shoulder belts fit in tightly against
the occupant's upper body in cer-
tain frontal collisions.
(2) EFD (Emergency Fastening Device)
The purpose of the EFD is to
make sure that the pelvis belts fit
in tightly against the occupant's
lower body in certain frontal colli-
sions.
If the system senses excessive ten-
sion on the driver or passenger's
seat belt when the pre-tensioner sys-
tem activates, the load limiter inside
the retractor pre-tensioner will
release some of the pressure on the
affected seat belt. (if equipped)
✽NOTICE - if equipped with
rollover sensor
The pre-tensioner will activate not
only in a frontal collision but also in
a side collision or rollover, if the
vehicle is equipped with a side or
curtain air bag.
✽NOTICE - without rollover
sensor
The pre-tensioner will activate not
only in a frontal collision but also in a
side collision, if the vehicle is equipped
with a side or curtain air bag.
WARNING
For your safety, be sure that the
belt webbing is not loose or
twisted and always sit properly
on your seat.

The seat belt pre-tensioner system
consists mainly of the following com-
ponents. Their locations are shown in
the illustration:
1. SRS air bag warning light
2. Retractor pre-tensioner assembly
3. SRS control module
4. Emergency fastening device (EFD)
✽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 operating condi-
tions and are not hazardous.
• Although it is harmless, the fine
dust may cause skin irritation and
should not be breathed for pro-
longed periods. Wash all exposed
skin areas thoroughly after an
accident in which the pre-tension-
er seat belts were activated.
• 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 instru-
ment panel will illuminate for
approximately 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 seatbelt must be worn
correctly and adjusted to the
proper position. Please read
and follow all of the important
information and precautions
about your vehicle’s occupant
safety features – including
seat belts and air bags – that
are provided in this manual.
2. Be sure you and your passen-
gers always wear seat belts
properly.

How does the air bag system
operate
• Air bags are activated (able to
inflate if necessary) only when the
ignition switch is turned to the ON
or START position.
• Air bags inflate instantly in the
event of serious frontal or side col-
lision (if equipped with side impact
air bag or curtain air bag) in order
to help protect the occupants from
serious physical injury.
✽NOTICE - if equipped with
rollover sensor
Also, the air bags inflate instantly in
the event of a rollover (if equipped
with a side airbag or curtain air bag)
in order to help protect the occu-
pants 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 vehi-
cles or objects which your vehicle
hits in the collision. The determin-
ing, 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 com-
partments after the 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 extremely short time in which a
collision occurs and the need to
get the air bag between the occu-
pant 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 air bag design.
However, air bag inflation can also
cause injuries which can include
facial abrasions, bruises and bro-
ken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances
under which contact with the
steering wheel air bag can cause
fatal injuries, especially if the
occupant is positioned exces-
sively close to the steering wheel.
(Continued)
• Keep the SRS parts and
wirings away from water or
any liquid. If the SRS compo-
nents are inoperative due to
exposure to water or liquids, it
may cause fire or severe
injury.

Passenger’s front air bag
OFF indicator (if equipped)
The passenger’s front air
bag OFF indicator illumi-
nates for about 4 seconds
after the ignition switch is
turned to the ON position.
The passenger’s front air bag OFF
indicator also comes on when the
passenger’s front air bag ON/OFF
switch is set to the OFF position and
goes off when the passenger’s front
air bag ON/OFF switch is set to the
ON position.
SRS components and func-
tions
The SRS consists of the following
components:
1. Driver's front air bag module
2. Front impact sensors
3. Passenger's front air bag module*
4. Pretensioner seatbelt systems*
5. Side impact sensors*
6. Curtain air bag modules*
7. Side air bag modules*
8. SRS control module (SRSCM)/
Rollover sensor*
9. Air bag warning light
ODMESA2005R
CAUTION
If the passenger’s front air bag
ON/OFF switch malfunctions,
the passenger’s front air bag
OFF indicator will not illuminate
(The passenger's front air bag
ON indicator comes on and goes
off after approximately 60 sec-
onds) and the passenger’s front
air bag will inflate in a frontal
impact even if the passenger’s
front air bag ON/OFF switch is
set to the OFF position.
If this occurs, we recommend
that the passenger’s front air
bag ON/OFF switch and the SRS
air bag system be inspected by
a HYUNDAI authorised repairer.

Curtain air bag (if equipped)
❈The actual air bags in the vehicle may dif-
fer from the illustration.
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.
(Continued)
• Do not use any accessory
seat covers.
• Use of seat covers could
reduce or prevent the effec-
tiveness 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 dangerous projec-
tiles 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 igni-
tion key is on.
(Continued)(Continued)
• If the seat or seat cover is
damaged, we recommend that
the system be serviced by a
HYUNDAI authorised repairer.

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 during certain side impact col-
lisions, depending on the crash sever-
ity, angle, speed and point of impact.
The curtain air bags do not only
deploy on the side of the impact but
also on the opposite side.
✽NOTICE - if equipped with
rollover sensor
Also, both sides of the side impact
air bags and curtain air bags deploy
in certain rollover situations.
• The curtain air bags are not
designed to deploy in all side
impacts.
(Continued)
• 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 are
seated on seats equipped with
side and/or curtain air bags.
• Never try to open or repair any
components of the side cur-
tain air bag system. We rec-
ommend that the system be
serviced by a HYUNDAI autho-
rised repairer.
Failure to follow the above men-
tioned instructions can result in
injury or death to the vehicle
occupants in an accident.WARNING
• In order for side impact and
curtain air bags to provide the
best protection, both front
seat occupants and both out-
board rear occupants should
sit in an upright position with
the seat belts properly fas-
tened.
Importantly, children should
sit in a proper child restraint
system in the rear seat.
• When children are seated in
the rear outboard seats, they
must be seated in the proper
child restraint system.
Make sure to put the child
restraint system as far away
from the door side as possible,
and secure the child restraint
system in a locked position.

Why didn’t my air bag go off in
a collision? (Inflation and non-
inflation conditions of the air
bag)
There are many types of accidents
in which the air bag would not be
expected to provide additional
protection.
These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts.
