Introduction
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask to an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane Rating of leaded gasoline is
same with unleaded one.
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 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 to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability 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.
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 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.)
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

Safety features of your vehicle
✽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 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.
• 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 approximate-
ly 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 seat belt 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 prop-
erly.
CAUTION
If the pre-tensioner seat belt is not
working 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, have an authorized
HYUNDAI dealer inspect the pre-
tensioner seat belt and SRS air bag
system as soon as possible.

Safety features of your vehicle
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
a 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 based upon the severity of a col-
lision and its direction. These two fac-
tors 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 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 the
extremely short time in which a collision
occurs and the need 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 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 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 passengers
should always move their seats
as far back as possible and sit
back in their seat.
• Air bags inflate instantly in the
event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
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 warning 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.
• The light blinks when the ignition
switch is in ON position.
SRS components and functions
The SRS consists of the following com-
ponents:
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*
*: if equippedThe SRSCM continually monitors all
SRS components while 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.
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 SRS air bag warning light " "
should go out.

WARNING
If any of the following conditions
occurs, this indicates a malfunction
of the SRS. Have an authorized
HYUNDAI dealer inspect the air bag
system as soon as possible.
• The light does not turn on briefly
when you turn the ignition ON.
• The light stays on after illuminat-
ing for approximately 6 seconds.
• The light comes on while the
vehicle is in motion.
• The light blinks when the ignition
switch is in ON position.

Safety features of your vehicle
Curtain air bag (if equipped)
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 occupants in cer-
tain side impact collisions.
WARNING
• The side impact air bag is sup-
plemental to the seat belt sys-
tems 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 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 and all rear (if
equipped) 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 the 9:00
and 3:00 positions. The passen-
ger’ arms and hands should be
placed on their laps.
• Do not use any accessory seat
covers.
(Continued)
(Continued)
• Use of seat covers could reduce
or prevent the effectiveness 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 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 the seat or seat cover is dam-
aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags.

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.

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.
1JBA3513
(Continued)
• Problems may arise if the sensor
installation angles are changed
due to the deformation of the
front bumper, body or B and C pil-
lars 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-gen-
uine parts may adversely affect
your vehicle’s collision and air
bag deployment performance.WARNING
• Do not hit or allow any objects to
impact the locations where air
bags 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.

Safety features of your vehicle
Side impact and curtain air bags
(if equipped)
Side impact and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
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 impact and 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,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces 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.
