Introduction
Petrol engine
Unleaded
We recommend to use unleaded
petrol which has 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 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.
•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.
WARNING
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.)

Safety system of your vehicle
The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:(1) SRS air bag warning light
(2) Retractor pre-tensioner (front)
(3) SRS control module
(4) Retractor pre-tensioner (rear)
(if equipped)
The sensor that activates the SRS
control module is connected with
the pre–tensioner seat belts. The
SRS air bag warning light on the
instrument cluster will illuminate
for approximately 6 seconds after
the ignition switch is placed in the
ON position, and then it should
turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminat-
ed or illuminates when the vehicle
is being driven, we recommend the
pre-tensioner seat belts and/or SRS
control module be inspected by a
HYUNDAI authorised repairer as
soon as possible.
NOTICE
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioner can become hot
and can burn you.
WARNING
Body work on the front area of
the vehicle may damage the
pre-tensioner seat belt system.
Therefore, we recommend the
system to be serviced by a
HYUNDAI authorised repairer.

Curtain air bags
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
and the rear outboard seat occu-
pants in certain side impact colli-
sions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.
The curtain air bags on both sides of
the vehicle are designed to deploy
when a rollover is detected by a
rollover sensor.
The curtain air bags are not
designed to deploy in all side impact
or rollover situations.
OTM038058
OTM038059
To reduce the risk of serious
injury or death from an inflating
curtain air bag, take the follow-
ing precautions:
•All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly.
WARNING
•Properly secure Child Restraint
System as far away from the
door as possible.
•Do not place any objects over
the air bag. Also, do not attach
any objects around the area the
air bag inflates such as the
door, side door glass, front and
rear pillar, roof side rail.
•Do not hang other objects
except clothes, especially
hard or breakable objects.
In an accident, it may cause
vehicle damage or personal
injury.
•Do not allow 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 seats.
•Do not open or repair the side
curtain air bags.

How does the air bags system
operate?
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 (front)
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors(10) Side pressure sensors
(11) Retractor pre-tensioner (rear)
(if equipped)
(12) Passenger’s front air bag OFF
indicator (front passenger's seat
only)
(13) Passenger’s front air bag
ON/OFF switch
The SRSCM continually 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.
SRS warning light
The SRS (Supplemental 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 elec-
trical system for malfunctions. The
light indicates that there is a potential
problem with your air bag system,
which could include your side and/or
curtain air bags used for rollover pro-
tection.

Safety system of your vehicle
During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driv-
er 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 or rollover by
supporting the side upper body area.
• 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 pro-
tect 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 collision and its direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic 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 vehicles
or objects which your vehicle
impacts during a 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 acci-
dent. 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 addition to inflating in serious
side collisions, vehicles equipped
with a rollover sensor, side and/or
curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, curtain
air bags will remain inflated longer
to help provide protection from ejec-
tion, especially when used in con-
junction with the seat belts. 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 condi-
tions occur, your SRS is mal-
functioning:
•The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
•The light stays on after illumi-
nating 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.
WARNING

Safety system of your vehicle
Why didn't my air bag go off in
a collision?
There are certain types of accidents
in which the air bag would not be
expected to provide additional protec-
tion. These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehicle
indicates a collision energy absorp-
tion, and is not an indicator of whether
or not an air bag should have inflated.
Air bag collision sensors
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
•Do not hit or allow any objects
to impact the locations where
air bags or sensors are
installed.
•Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
•Do not install bumper guards
or replace the bumper with a
non-genuine part. This may
adversely affect the collision
and air bag deployment per-
formance.
WARNING
•Place the ignition switch to
the LOCK/OFF or ACC posi-
tion, when the vehicle is being
towed to prevent inadvertent
air bag deployment.
•We recommend that all air bag
repairs are conducted by a
HYUNDAI authorised repairer.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the severity, speed or angles of
impact of the front collision.
Side and curtain air bags
Side and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the severity, speed or
angles of impact resulting from a
side impact collision.Although the driver’s and front pas-
senger’s air bags are designed to
inflate in frontal collisions, they also
may inflate in other types of colli-
sions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed to
inflate in side impact collisions, but
they may inflate in other collisions if
the side impact sensors detect a suf-
ficient impact.
Also, the side and curtain air bags
are designed to inflate when a
rollover is detected by a rollover sen-
sor.
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.

Safety system of your vehicle
In an 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
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. 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 significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
Information
The side and curtain air bags may
inflate in a rollover situation, when it
is detected by the rollover sensor.

the button extinguishes) the sys-
tem judges that the driver unlocked
the door acknowledging the rear
status and the lock is released
regardless of the rear status.
3. When an approaching vehicle from
the rear is detected the moment the
door is opened, the “Watch for traf-
fic” warning message appears on
the cluster and a warning sounds.
- The above 2 and 3 functions are
activated when you select “Driver
assistance →Blind-spot safety →
SEA (Safe Exit Assist)” from the
User Settings mode on the cluster.
- The Electronic child safety lock
system will operate for approxi-
mately 10 minutes after the igni-
tion key is removed or turned to
the LOCK (or OFF) position. After
about 10 minutes, the indicator
on the button turns off and you
can not deactivate the Electronic
child safety lock system. To deac-
tivate the Electronic child safety
lock system, press the Electronic
child safety lock button again with
the ignition switch in the ON posi-
tion or after starting the engine.- When the power is supplied
again after removing the battery
or battery discharge whilst the
child safety lock in the lock posi-
tion, press the rear door lock but-
ton once again to match the state
of the indicator on the rear door
lock button and actual status of
the rear door child safe lock.
- If the airbag is activated whilst the
rear door lock button is ON (the
indicator on the button illuminates)
it automatically switches OFF and
the rear door is unlocked.
