Introduction
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.
Gasoline containing alcohol andmethanol
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 to 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.
CAUTION
NEVER USE LEADED FUEL. The use of leaded fuel is detrimental tothe catalytic converter and willdamage the engine control sys-tem’s oxygen sensor and affect emission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consultan authorized HYUNDAI dealer fordetails.)
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 containsmethanol. Discontinue use of anygasohol product which impairs dri- vability.

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 approximately 6
seconds after the ignition switch has
been turned to the ON position, and
then it should turn off.CAUTION
If the pre-tensioner seat belt is not
working properly, this warning lightwill illuminate even if there is no malfunction of the SRS air bag. Ifthe SRS air bag warning light doesnot illuminate when the ignition key is turned to ON, or if it remains illu-minated after illuminating for approximately 6 seconds, or if itilluminates while the vehicle is being driven, please have anauthorized HYUNDAI dealer inspectthe pre-tensioner seat belt or SRSair bag system as soon as possible.
WARNING
Pre-tensioners are designed to operate only one time. After acti-
vation, pre-tensioner seat belts
must be replaced. All seat belts,
of any type, should always be
replaced after they have been
worn during a collision.
(Continued)
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.

How does the air bag system
operate
Air bags are activated (able to inflate ifnecessary) 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 impact 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 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 injuryor death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possible
(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.

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*
10. Driver’s knee air bag module*
11. Passenger’s front air bag ON/OFFindicator* 12. Passenger’s front air bag ON/OFF
switch*
* : if equipped
The SRSCM continually monitors all ele-
ments while the ignition switch is ON to
determine if a frontal, near-frontal impact
or side 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
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.

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. The curtain air bags are designed to
deploy during certain side impact colli-
sions, depending on the crash severity,
angle, speed and point of impact. The
curtain air bags are not designed to
deploy in all side impact situations, colli-
sions from the front or rear of the vehicle
or in most rollover situations.

(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 key is
on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer. Inform that 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. 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 toimpact 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)
(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B pillar and
C pillars where side collision sen-
sors are installed. Have the vehi-
cle 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 vehicles collision and air
bag deployment performance.

Side impact and curtain air bags
(if equipped)
Side impact and/or 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 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
or sidewalks, air bags may deploy. Drive
carefully on unimproved roads or on sur-
faces 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.

Safety system of your vehicle
Air bags are not designed to inflate inrear collisions, because occupants are
moved backward by the force of the
impact. In this case, inflated air bags
would not be able to provide any addi-
tional 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, frontal air bag
deployment would not provide addi-
tional occupant protection.
However, if equipped with side impact and 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 bene-
fit, 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 signifi-
cantly replaced by such “under-ride”
collisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, side 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 air
bags 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.
