Introduction
A020102APB
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane Rating of leaded gasoline is
same with unleaded one.
A020103APB
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage the fuel system.
Discontinue using gasohol 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 use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
(Except for vehicle designed to use
leaded gasoline for some countries)
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized 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 gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

✽NOTICE
• Both the driver's and front passen-
ger's pre-tensioner seat belts will be
activated in certain frontal collisions.
• 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.
✽NOTICE
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 approximately 6 sec-
onds after the ignition switch has been
turned to the ON position, and then it
should turn off.
CAUTION
If the pre-tensioner seat belt does
not work properly, this warning
light will illuminate even if there is
no malfunction of the SRS air bag. If
the SRS air bag warning light does
not illuminate when the ignition
switch is turned to ON, or if it
remains illuminated after illuminat-
ing for approximately 6 seconds, or
if it illuminates while the vehicle is
being driven, please have an
authorized HYUNDAI dealer inspect
the pre-tensioner seat belt or SRS
air bag system as soon as possible.
WARNING
To obtain maximum benefit from a
pre-tensioner seat belt:
1. The seatbelt must be worn cor-
rectly and adjusted to the proper
position. Please read and follow
all of the important information
and precautions about your vehi-
cle’s occupant safety features –
including seat belts and air bags
– that are provided in this manu-
al.
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 collision (if
equipped with side air bag or curtain
air bag) in order to help protect 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 by the severity of a collision and
its direction. These two factors deter-
mine 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 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 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 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 collision
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 broken bones
because 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 to
the 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 possi-
ble (at least 250 mm (10 inches)
away). The front passenger
should always move their seat as
far back as possible and sit back
in their 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.

Air bag warning light
The purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the indicator light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
• The light does not turn on briefly when
you turn the ignition ON.
• The light stays on after illuminating for
approximately 6 seconds.
• The light comes on while the vehicle is
in motion.

WARNING
• Extreme Hazard! Do not use a
rearward facing child restraint on
a seat protected by an air bag in
front of it!
• Never put a child restraint in the
front passenger’s seat. If the
front passenger air bag inflates, it
can cause serious or fatal
injuries.
• When children are seated in the
rear outboard seats of a vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,
and securely lock the child
restraint system in position.

The side impact air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and point of impact. The
side impact air bags are not designed to
deploy in all side impact situations.(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 switch
is on.
• If seat or seat cover is damaged,
have the vehicle checked and
repaired by an authorized
HYUNDAI dealer. Inform that your
vehicle is equipped with side
impact air bags.WARNING
• The side impact air bag is supple-
mental 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 while the vehicle
is in motion. The air bags deploy
only in certain side impact condi-
tions 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 should
sit in an upright position with the
seat belt properly fastened. The
driver's hands should be placed
on the steering wheel at 9:00 and
3:00 positions. The passenger's
arms and hands should be
placed on their laps.
• Never place accessory seat cov-
ers, blankets or aftermarket seat
warmers on the passenger seat
as these may interfere with the
side impact air bag deployment.

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
expected to provide additional protec-
tion.
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 front
collision.
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 injury
or 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
authorized HYUNDAI dealer.
(Continued)
• Problems may arise if the sensor
installation 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
authorized HYUNDAI dealer.
• Your vehicle has been designed
to absorb impact and deploy the
air bag(s) in certain collisions.
Installing 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 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 or
angles of impact resulting from a side
impact 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) are
designed to inflate only in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
air bags may deploy. Drive carefully on
unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
C040802APB
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.
OSA038120

Safety system of your vehicle
• Front 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, front air bag
deployment would not provide addi-
tional occupant protection.
However, if equipped with side impact
or curtain air bags, the air bags may
inflate depending on the intensity, vehi-
cle speed and angles of impact.• 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 ben-
efit, 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 high-
er ground clearance. Air bags may not
inflate in this "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly replaced by such “under-ride”
collisions.• Air bags may not inflate in rollover
accidents because air bag deployment
would not provide protection to the
occupants.
However, side impact 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 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 to one area and
the full force of the impact is not deliv-
ered to the sensors.
