2FUEL RECOMMENDATIONS
B010A02A-AAT
Use Unleaded Gasoline
Unleaded gasoline with a Pump Octane Rating
of 87 (Research Octane Number 91) or higher
must be used in your Hyundai.
If leaded gasoline is used, it will cause the
catalytic converter to become ineffective and
the emission control system to malfunction.
This can also result in increased maintenance
expense.
To avoid accidental use of leaded fuel, the larger
nozzle used with leaded gasoline at service
stations cannot be inserted into the fuel tank
opening of your Hyundai.
B010A03E
UNLEADED
FUEL ONLY
CAUTION:o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o The fuel cap must be tightened at least
3 clicks, otherwise " " light may illu-
minate.
!
B010B01A-AAT
What About Gasohol?
Gasohol (a mixture of 90% unleaded gasoline
and 10% ethanol or grain alcohol) may be used
in your Hyundai. However, if your engine devel-
ops driveability problems, the use of 100%
unleaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
B010C01A-AAT
Use of MTBE
Hyundai recommends that fuels containing
MTBE (Methyl Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight) should not
be used in your Hyundai.
Fuel containing MTBE over 15.0% vol. (Oxygen
Content 2.7% weight) may reduce vehicle per-
formance and produce vapor lock or hard
starting.
B010D01A-AAT
Do Not Use Methanol
Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel
can reduce vehicle performance and damage
components of the fuel system.
!CAUTION:Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuel
system and any performance problems that
are caused by the use of fuels containing
methanol or fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol. (Oxy-
gen Content 2.7% weight.).

NOTE:o Both the driver's and front passenger's
pre-tensioner seat belts will be activated
in certain frontal collisions. The pre-
tensioner seat belts can be activated
alone or, where the frontal collision is
severe enough, together with the
airbags.
The pre-tensioners will not be activated
if the seat belts are not being worn at the
time of the collision.
o 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 com-
partment. These are normal operating
conditions and are not hazardous.
CAUTION:o The sensor that activates the SRS airbag
is connected with the pre-tensioner seat
belt. The SRS airbag warning light on
the instrument panel will blink for ap-
proximately 6 seconds after the ignition
key has been turned to the "ON" posi-
tion, and then it should turn off.
o If the pre-tensioner seat belt is not work-
ing properly, this warning light will illu-
minate even if there is no malfunction of
the SRS airbag system.
If the SRS airbag warning light does not
illuminate when the ignition key is turned
to "ON", or if it remains illuminated after
blinking 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 belts and SRS airbag system as
soon as possible.
WARNING:o Pre-tensioners are designed to operate
only one time. After activation, 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.
o The pre-tensioner seat belt assembly
mechanisms become hot during activa-
tion. Do not touch the pre-tensioner seat
belt assemblies for several minutes after
they have been activated.
o Do not attempt to inspect or replace the
pre-tensioner seat belts yourself. This
must be done by an authorized Hyundai
dealer.
o Do not strike the pre-tensioner seat belt
assemblies.
o Do not attempt to service or repair the
pre-tensioner seat belt system in any
manner.
o Improper handling of the pre-tensioner
seat belt assemblies, and failure to heed
the warnings to not strike, modify, in-
spect, replace, service or repair the pre-
tensioner seat belt assemblies may lead
to improper operation or inadvertent
activation and serious injury.
o Always wear the seat belts when driving
or riding in a motor vehicle.
!
!WARNING:To obtain maximum benefit from a pre-
tensioner seat belt:
1. The seat belt must be worn correctly.
2. The seat belt must be adjusted to the
correct position.
3. Be sure you and your passengers always
wear seat belts and wear then properly.o Although it is harmless, the fine dust
may cause skin irritation and should not
be breathed for prolonged periods. Wash
your hands and face thoroughly after an
accident in which the pre-tensioner seat
belts were activated.

!WARNING:
o No objects should be placed over or near
the airbag modules on the steering
wheel, instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to deploy.
o If the airbags deploy, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring, or other components of the SRS
system. Doing so could result in injury,
due to accidental deployment of the
airbags or by rendering the SRS inopera-
tive.
o Do not install a child restraint system in
the front passenger seat position. A
child restraint system must never be
placed in the front seat. The infant or
child could be severely injured or killed
by an airbag deployment in case of an
accident.
o Do not allow children to ride in the front
passenger seat. If older children (teen-
agers and older) must ride in the front
seat, make sure they are always properly
belted and the seat is moved back as far
as possible.o For maximum safety protection in all
types of crashes, all occupants includ-
ing the driver should always wear their
seat belts whether or not an airbag is
also provided at their seating position to
minimize the risk of severe injury or
death in the event of a crash. Do not sit
or lean unnecessarily close to the airbag
while the vehicle is in motion.
o Sitting improperly or out of position can
result in serious or fatal injury in a crash.
All occupants should sit upright in their
seats with their feet on the floor until the
vehicle is parked and the ignition key is
removed.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.

The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal
or near-frontal impact is severe enough to
require airbag deployment or pre-tensioner seat
belt deployment.
The SRS service reminder indicator (SRI) on
the instrument panel will blink for about 6 sec-
onds after the ignition key is turned to the "ON"
position or after the engine is started, after which
the SRI should go out.
The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box. When
the SRSCM detects a considerable impact to
the front of the vehicle, it will automatically
deploy the front airbags.
B240B01L
B240B02L
Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Further
opening of the covers then allows full inflation of
the airbags.A fully inflated airbag, in combination with a
properly worn seat belt, slows the driver's or the
passenger's forward motion, reducing the
risk of head and chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.

SRS Care
o The SRS is virtually maintenance free and
there are no parts you can safely service by
yourself. The entire SRS system must be
inspected by an authorized Hyundai dealer
10 years after the date that the vehicle was
manufactured.
o Any work on the SRS system, such as
removing, installing, repairing, or any work
on the steering wheel or front seats must be
performed by a qualified Hyundai technician.
Improper handling of the airbag system may
result in serious personal injury.!
o For best protection from the side impact
airbag system and to avoid being injured
by the deploying side impact airbag,
both front seat occupants should sit in
an upright position with their feet on the
floor and the seat belt properly fastened.
The driver's hands should be placed on
the steering wheel at the 9:00 and 3:00
o'clock positions.
The passenger's arms and hands should
be placed on their laps.
o Do not use any accessory seat covers.
o Use of seat covers could reduce or prevent
the effectiveness of the system.
o Do not install any accessories on the side
or near the side impact airbag.
o Do not use excessive force on the side of
the seat.
o Do not place any objects over the airbag or
between the airbag and yourself.
o 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 airbag inflates.
o To prevent unexpected deployment of the
side impact air bag that may result in
personal injury, avoid impact to the side
impact airbag sensor when the ignition
key is on.WARNING:
WARNING:o The side impact airbag is supplemental
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 airbags deploy only in cer-
tain side impact conditions severe
enough to cause significant injury to the
vehicle occupants.

!
B260B01A-AAT
SRS (Airbag) Service
Reminder Indicator (SRI)
The SRS service reminder indicator (SRI) comes
on and flashes for about 6 seconds after the
ignition key is turned to the "ON" position or after
the engine is started, after which it will go out.
This light also comes on when the SRS is not
working properly. If the SRI does not come on,
or continuously remains on after flashing for
about 6 seconds when you turned the ignition
key to the "ON" position or started the engine,
or if it comes on while driving, have the SRS
inspected by an authorized Hyundai Dealer.
B260P01E-GAT
ABS Service Reminder
Indicator (SRI) (If installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System will come on and then
go off after three seconds. If the ABS SRI
remains on, comes on while driving, or does not
come on when the key is turned to the "ON"
position, this indicates that there may be a
problem with the ABS.
If this occurs, have your vehicle checked by
your Hyundai dealer as soon as possible. The
normal braking system will still be operational,
but without the assistance of the anti-lock brake
system.
B260D01A-AAT
Turn Signal Indicator Lights
The blinking green arrows on the instrument
panel show the direction indicated by the turn
signals. If the arrow comes on but does not blink,
blinks more rapidly than normal, or does not
illuminate at all, a malfunction in the turn signal
system is indicated. Your dealer should be
consulted for repairs.
B260F01A-AAT
High Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to high beam
of flash position.
WARNING:If the both ABS SRI and Parking Brake/
Brake fluid level warning lights remain "ON"
or come on while driving, there may be a
problem with E.B.D (Electronic brake force
distribution).
If this occurs, avoid sudden stops and have
your vehicle checked by your Hyundai dealer
as soon as possible.
