Petrol engine
Unleaded
For the optimal vehicle performance, we recommend you use unleaded petrol which
has an octane rating of RON (Research Octane Number) 95 / AKI (Anti Knock Index)
91 or higher. You may use unleaded petrol with an octane rating of RON 91-94 / AKI
87-90 but it may result in slight performance reduction of the vehicle. (Do not use
methanol blended fuels)
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimise 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 a HYUNDAI authorised repairer for
details.)
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 accident.

Safety system
8KMB3311/H
The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration above:
(1) SRS air bag warning light
(2) Front retractor pre-tensioner
(if equipped)
(3) SRS control module
OBC3030012R
„Rear
(4) Rear retractor pre-tensioner
(if equipped)
NOTICE
The sensor that activates the SRS
air bag is connected with the pre–
tensioner seat belts. The SRS air bag
warning light on the instrument panel
will illuminate for approximately 6
seconds after the ignition switch is
placed to 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 air bags
be inspected by a HYUNDAI authorised
repairer as soon as possible.

Safety system
How does the air bags system
operate?
OBC3030023R
The SRS consists of the following
components:
(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*
(10) Side pressure sensors*
(11) Passenger’s front air bag OFF
indicator (front passenger’s seat
only) *
(12) Passenger’s front air bag ON/OFF
switch *
* : if equipped
The SRSCM continually monitors SRS
components whilst the ignition switch
is in the ON position to determine if a
crash impact is severe enough to require
air bag deployment or pre-tensioner seat
belt deployment.
SRS warning light
The SRS (Supplement Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your air
bag system.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:

[The light does not turn on for
approximately six seconds when the
ignition switch is in the ON position.

[The light stays on after illuminating
for approximately six seconds.

[The light comes on whilst the vehicle
is in motion.

[The light blinks when the engine is
running.
We recommend that a HYUNDAI
authorised repairer inspect the SRS
as soon as possible if any of these
conditions occur.

During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact.

[Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.

[Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.

[Generally, air bags are designed to
inflate based upon the severity of a
collision and it’s direction etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.

[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.
[To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
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 and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken 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 air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to reduce the risk of
being injured by an inflating air bag. The
greatest risk is sitting too close to the air
bag. An air bag needs space to inflate.
It is recommended that drivers sit as far
as possible between the centre of the
steering wheel and the chest whilst still
maintaining control of the vehicle.
